Sets the widget's 'access key'. This key is used (in conjunction with a browser-specific modifier key) to automatically focus the widget.

@param key the widget's access key

void set accessKey(int key) {
 //Dom.setElementProperty(getElement(), "accessKey", "" + key);
}

Gets whether this widget is enabled.

@return <code>true</code> if the widget is enabled

bool get enabled => !inputElem.disabled;

Sets whether this widget is enabled.

@param enabled <code>true</code> to enable the widget, <code>false</code>

     to disable it

void set enabled(bool val) {
 //Dom.setElementPropertyBoolean(inputElem, "disabled", !val);
 inputElem.disabled = !val;
 if (val) {
   removeStyleDependentName("disabled");
 } else {
   addStyleDependentName("disabled");
 }
}

Explicitly focus/unfocus this widget. Only one widget can have focus at a time, and the widget that does will receive all keyboard events.

@param focused whether this widget should take focus or release it

void set focus(bool focused) {
 if (focused) {
   inputElem.focus();
 } else {
   inputElem.blur();
 }
}

Returns the value property of the input element that backs this widget. This is the value that will be associated with the CheckBox name and submitted to the server if a {@link FormPanel} that holds it is submitted and the box is checked. <p> Don't confuse this with {@link #getValue}, which returns true or false if the widget is checked.

String get formValue => inputElem.value;

Set the value property on the input element that backs this widget. This is the value that will be associated with the CheckBox's name and submitted to the server if a {@link FormPanel} that holds it is submitted and the box is checked. <p> Don't confuse this with {@link #setValue}, which actually checks and unchecks the box.

@param value

void set formValue(String val) {
 inputElem.value = val;
}

Gets this object's contents as HTML.

@return the object's HTML

String get html {
 return directionalTextHelper.getTextOrHtml(true);
}

Sets this object's contents via HTML. Use care when setting an object's HTML; it is an easy way to expose script-based security problems. Consider using {@link #setText(String)} whenever possible.

@param html the object's new HTML

void set html(String val) {
 directionalTextHelper.setTextOrHtml(val, true);
}

Gets the widget's name.

@return the widget's name

String get name => inputElem.name;

Gets the widget's position in the tab index.

@return the widget's tab index

int get tabIndex => inputElem.tabIndex;

Sets the widget's position in the tab index. If more than one widget has the same tab index, each such widget will receive focus in an arbitrary order. Setting the tab index to <code>-1</code> will cause this widget to be removed from the tab order.

@param index the widget's tab index

void set tabIndex(int index) {
 // Need to guard against call to setTabIndex before inputElem is
 // initialized. This happens because FocusWidget's (a superclass of
 // CheckBox) setElement method calls setTabIndex before inputElem is
 // initialized. See CheckBox's protected constructor for more information.
 if (inputElem != null) {
   inputElem.tabIndex = index;
 }
}

Sets the element's text.

String get text => directionalTextHelper.getTextOrHtml(false);

Get the element's text.

void set text(String val) {
 directionalTextHelper.setTextOrHtml(val, false);
}

Gets the title associated with this object. The title is the 'tool-tip' displayed to users when they hover over the object.

@return the object's title

String get title => getElement().title;

Sets the element's title.

void set title(String value) {
 getElement().title = value;
}

Determines whether or not this object is visible. Note that this does not necessarily take into account whether or not the receiver's parent is visible, or even if it is attached to the Document. The default implementation of this trait in UIObject is based on the value of a dom element's style object's display attribute.

@return <code>true</code> if the object is visible

bool get visible => isVisible(getElement());

Sets whether this object is visible.

@param visible <code>true</code> to show the object, <code>false</code> to

     hide it

void set visible(bool visible) {
 setVisible(getElement(), visible);
}

Gets whether word-wrapping is enabled.

@return <code>true</code> if word-wrapping is enabled.

bool get wordWrap => WhiteSpace.NOWRAP.value != getElement().style.whiteSpace;

Sets whether word-wrapping is enabled.

@param wrap <code>true</code> to enable word-wrapping.

void set wordWrap(bool wrap) {
 getElement().style.whiteSpace = wrap ? WhiteSpace.NORMAL.value : WhiteSpace.NOWRAP.value;
}

Adds an AttachEvent handler.

@param handler the handler @return the handler registration

For <a href= "http://code.google.com/p/google-web-toolkit/wiki/UnderstandingMemoryLeaks"

browsers which do not leak</a>, adds a native event handler to the widget.

Note that, unlike the {@link #addDomHandler(EventHandler, com.google.gwt.event.dom.client.DomEvent.Type)} implementation, there is no need to attach the widget to the DOM in order to cause the event handlers to be attached.

Adds a dependent style name by specifying the style name's suffix. The actual form of the style name that is added is:

getStylePrimaryName() + '-' + styleSuffix

@param styleSuffix the suffix of the dependent style to be added. @see #setStylePrimaryName(String) @see #removeStyleDependentName(String) @see #setStyleDependentName(String, boolean) @see #addStyleName(String)

void addStyleDependentName(String styleSuffix) {
 setStyleDependentName(styleSuffix, true);
}

Adds a secondary or dependent style name to this object. A secondary style name is an additional style name that is, in HTML/CSS terms, included as a space-separated token in the value of the CSS <code>class</code> attribute for this object's root element.

The most important use for this method is to add a special kind of secondary style name called a dependent style name. To add a dependent style name, use {@link #addStyleDependentName(String)}, which will prefix the 'style' argument with the result of {@link #k()} (followed by a '-'). For example, suppose the primary style name is gwt-TextBox. If the following method is called as obj.setReadOnly(true):

public void setReadOnly(boolean readOnly) {
  isReadOnlyMode = readOnly;
  // Create a dependent style name.
  String readOnlyStyle = "readonly";
  if (readOnly) {
addStyleDependentName(readOnlyStyle);

  } else {
removeStyleDependentName(readOnlyStyle);

  }
}</pre>

then both of the CSS style rules below will be applied:
// This rule is based on the primary style name and is always active.
.gwt-TextBox {
  font-size: 12pt;
}
// This rule is based on a dependent style name that is only active
// when the widget has called addStyleName(getStylePrimaryName() +
// "-readonly").
.gwt-TextBox-readonly {
  background-color: lightgrey;
  border: none;
}</pre>

The code can also be simplified with
{@link #setStyleDependentName(String, boolean)}:
public void setReadOnly(boolean readOnly) {
  isReadOnlyMode = readOnly;
  setStyleDependentName("readonly", readOnly);
}

Dependent style names are powerful because they are automatically updated
whenever the primary style name changes. Continuing with the example above,
if the primary style name changed due to the following call:
setStylePrimaryName("my-TextThingy");

then the object would be re-associated with following style rules, removing
those that were shown above.
.my-TextThingy {
  font-size: 20pt;
}
.my-TextThingy-readonly {
  background-color: red;
  border: 2px solid yellow;
}</pre>

Secondary style names that are not dependent style names are not
automatically updated when the primary style name changes.

@param style the secondary style name to be added
@see UIObject
@see #removeStyleName(String)
void addStyleName(String style) {
 setStyleName(style, true);

Clears all of the object's style names and sets it to the given style. You should normally use {@link #setStylePrimaryName(String)} unless you wish to explicitly remove all existing styles.

@param style the new style name @see #setStylePrimaryName(String)

void clearAndSetStyleName(String style) {
 setElementStyleName(getStyleElement(), style);
}

Creates the SimpleEventBus used by this Widget. You can override this method to create a custom EventBus.

@return the EventBus you want to use.

EventBus createEventBus() {
 return new SimpleEventBus();
}

Fires an event on a child widget. Used to delegate the handling of an event from one widget to another.

@param event the event @param target fire the event on the given target

void delegateEvent(Widget target, DwtEvent event) {
 target.fireEvent(event);
}

If a widget contains one or more child widgets that are not in the logical widget hierarchy (the child is physically connected only on the DOM level), it must override this method and call {@link #onAttach()} for each of its child widgets.

@see #onAttach()

void doAttachChildren() {
}

If a widget contains one or more child widgets that are not in the logical widget hierarchy (the child is physically connected only on the DOM level), it must override this method and call {@link #onDetach()} for each of its child widgets.

@see #onDetach()

void doDetachChildren() {
}

{@inheritDoc} <p> See note at {@link #setDirectionEstimator(DirectionEstimator)}.

void enableDirectionEstimator(bool enabled) {

Ensures the existence of the event bus.

@return the EventBus.

EventBus ensureHandlers() {
 return _eventBus == null ? _eventBus = createEventBus() : _eventBus;
}

Intended to be used to pull the value out of a CSS length. If the value is "auto" or "inherit", 0 will be returned.

@param s The CSS length string to extract @return The leading numeric portion of <code>s</code>, or 0 if "auto" or

    "inherit" are passed in.

double extractLengthValue(String s) {
 if (s == "auto" || s == "inherit" || s == "") {
   return 0.0;
 } else {
   // numberRegex divides the string into a leading numeric portion
   // followed by an arbitrary portion.
   if(numberRegex.hasMatch(s)) {
     // Extract the leading numeric portion of string
     s = numberRegex.firstMatch(s)[0];
   }
   return double.parse(s);
 }
}

Fires the given event to the handlers listening to the event's type.

Any exceptions thrown by handlers will be bundled into a UmbrellaException and then re-thrown after all handlers have completed. An exception thrown by a handler will not prevent other handlers from executing.

@param event the event

void fireEvent(DwtEvent event) {
//    if (_eventBus != null) {
//      _eventBus.fireEvent(event);
//    }
 if (_eventBus != null) {
   // If it not live we should revive it.
   if (!event.isLive()) {
     event.revive();
   }
   Object oldSource = event.getSource();
   event.overrideSource(getElement());
   try {

     // May throw an UmbrellaException.
     _eventBus.fireEventFromSource(event, getElement());
   } on UmbrellaException catch (e) {
     throw new UmbrellaException(e.causes);
   } finally {
     if (oldSource == null) {
       // This was my event, so I should kill it now that I'm done.
       event.kill();
     } else {
       // Restoring the source for the next handler to use.
       event.overrideSource(oldSource);
     }
   }

DirectionEstimator getDirectionEstimator() {
 return directionalTextHelper.getDirectionEstimator();
}

Gets this object's browser element.

dart_html.Element getElement() {
 assert (_element != null); // : MISSING_ELEMENT_ERROR;
 return _element;
}

Return EventBus.

EventBus getEventBus() {
 return _eventBus;
}

Gets the panel-defined layout data associated with this widget.

@return the widget's layout data @see #setLayoutData

Object getLayoutData() {
 return _layoutData;
}

Gets the object's offset height in pixels. This is the total height of the object, including decorations such as border and padding, but not margin.

@return the object's offset height

int getOffsetHeight() {
 return getElement().offset.height; // Dom.getElementPropertyInt(getElement(), "offsetHeight");
}

Gets the object's offset width in pixels. This is the total width of the object, including decorations such as border and padding, but not margin.

@return the object's offset width

int getOffsetWidth() {
 return getElement().offset.width; // Dom.getElementPropertyInt(getElement(), "offsetWidth");
}

Gets this widget's parent panel.

@return the widget's parent panel

Widget getParent() {
 return _parent;
}

Template method that returns the element to which style names will be applied. By default it returns the root element, but this method may be overridden to apply styles to a child element.

@return the element to which style names will be applied

dart_html.Element getStyleElement() {
 return getElement();
}

Gets all of the object's style names, as a space-separated list. If you wish to retrieve only the primary style name, call {@link #getStylePrimaryName()}.

@return the objects's space-separated style names @see #getStylePrimaryName()

String getStyleName() {
 return getElementStyleName(getStyleElement());
}

Gets the primary style name associated with the object.

@return the object's primary style name @see #setStyleName(String) @see #addStyleName(String) @see #removeStyleName(String)

Determines whether this check box is currently checked. <p> Note that this <em>does not</em> return the value property of the checkbox input element wrapped by this widget. For access to that property, see {@link #getFormValue()}

@return <code>true</code> if the check box is checked, false otherwise.

    Will not return null

bool getValue() {

Returns whether or not the receiver is attached to the {@link com.google.gwt.dom.client.Document Document}'s {@link com.google.gwt.dom.client.BodyElement BodyElement}.

@return true if attached, false otherwise

bool isAttached() {
 return _attached;
}

Has this widget ever been attached?

@return true if this widget ever been attached to the DOM, false otherwise

bool isOrWasAttached() {
 return eventsToSink == -1;
}

This method is called when a widget is attached to the browser's document. To receive notification after a Widget has been added to the document, override the {@link #onLoad} method or use {@link #addAttachHandler}.

It is strongly recommended that you override {@link #onLoad()} or {@link #doAttachChildren()} instead of this method to avoid inconsistencies between logical and physical attachment states.

Subclasses that override this method must call super.onAttach() to ensure that the Widget has been attached to its underlying Element.

@throws IllegalStateException if this widget is already attached @see #onLoad() @see #doAttachChildren()

void onAttach() {
 super.onAttach();

 // Accessibility: setting tab index to be 0 by default, ensuring element
 // appears in tab sequence. We must ensure that the element doesn't already
 // have a tabIndex set. This is not a problem for normal widgets, but when
 // a widget is used to wrap an existing static element, it can already have
 // a tabIndex.
 if (-1 == tabIndex) {
   tabIndex = 0;
 }
}

This method is called when a widget is detached from the browser's document. To receive notification before a Widget is removed from the document, override the {@link #onUnload} method or use {@link #addAttachHandler}.

It is strongly recommended that you override {@link #onUnload()} or {@link #doDetachChildren()} instead of this method to avoid inconsistencies between logical and physical attachment states.

Subclasses that override this method must call super.onDetach() to ensure that the Widget has been detached from the underlying Element. Failure to do so will result in application memory leaks due to circular references between DOM Elements and JavaScript objects.

@throws IllegalStateException if this widget is already detached @see #onUnload() @see #doDetachChildren()

void onDetach() {
 if (!isAttached()) {
   throw new Exception("Should only call onDetach when the widget is attached to the browser's document");
 }

 try {
   // onUnload() gets called *before* everything else (the opposite of
   // onLoad()).
   onUnload();
   AttachEvent.fire(this, false);
 } finally {
   // Put this in a finally, just in case onUnload throws an exception.
   try {
     doDetachChildren();
   } finally {
     // Put this in a finally, in case doDetachChildren throws an exception.
     Dom.setEventListener(getElement(), null);
     _attached = false;
   }
 }
}

This method is called when a widget is attached to the browser's document. onAttach needs special handling for the CheckBox case. Must still call {@link Widget#onAttach()} to preserve the <code>onAttach</code> contract.

void onLoad() {
 setEventListener(inputElem, this);
}

This method is called when a widget is detached from the browser's document. Overridden because of IE bug that throws away checked state and in order to clear the event listener off of the <code>inputElem</code>.

void onUnload() {
 // Clear out the inputElem's event listener (breaking the circular
 // reference between it and the widget).
 setEventListener(inputElem, null);
 setValue(getValue(), false);
}

Removes this widget from its parent widget, if one exists.

If it has no parent, this method does nothing. If it is a "root" widget (meaning it's been added to the detach list via {@link RootPanel#detachOnWindowClose(Widget)}), it will be removed from the detached immediately. This makes it possible for Composites and Panels to adopt root widgets.

@throws IllegalStateException if this widget's parent does not support

      removal (e.g. {@link Composite})

void removeFromParent() {
 if (_parent == null) {
   // If the widget had no parent, check to see if it was in the detach list
   // and remove it if necessary.
   if (RootPanel.isInDetachList(this)) {
     RootPanel.detachNow(this);
   }
 } else if (_parent is HasWidgets) {
   (_parent as HasWidgets).remove(this);
 } else if (_parent != null) {
   throw new Exception("This widget's parent does not implement HasWidgets");
 }
}

Removes a dependent style name by specifying the style name's suffix.

@param styleSuffix the suffix of the dependent style to be removed @see #setStylePrimaryName(Element, String) @see #addStyleDependentName(String) @see #setStyleDependentName(String, boolean)

void removeStyleDependentName(String styleSuffix) {
 setStyleDependentName(styleSuffix, false);
}

Removes a style name. This method is typically used to remove secondary style names, but it can be used to remove primary stylenames as well. That use is not recommended.

@param style the secondary style name to be removed @see #addStyleName(String) @see #setStyleName(String, boolean)

void removeStyleName(String style) {
 setStyleName(style, false);
}

Replaces this object's browser element.

This method exists only to support a specific use-case in Image, and should not be used by other classes.

@param elem the object's new element

void replaceElement(dart_html.Element elem) {
 if (isAttached()) {
   // Remove old event listener to avoid leaking. onDetach will not do this
   // for us, because it is only called when the widget itself is detached
   // from the document.
   Dom.setEventListener(getElement(), null);
 }

 super.replaceElement(elem);

 if (isAttached()) {
   // Hook the event listener back up on the new element. onAttach will not
   // do this for us, because it is only called when the widget itself is
   // attached to the document.
   Dom.setEventListener(getElement(), this);
 }
}

Replace the current input element with a new one. Preserves all state except for the name property, for nasty reasons related to radio button grouping. (See implementation of {@link RadioButton#setName}.)

@param elem the new input element

void replaceInputElement(dart_html.InputElement newInputElem) {
 // Collect information we need to set
 int _tabIndex = tabIndex;
 bool _checked = getValue();
 bool _enabled = enabled;
 String _formValue = formValue;
 String _uid = inputElem.id;
 //String accessKey = inputElem.getAccessKey();
 int sunkEvents = IEvent.getEventsSunk(inputElem);

 // Clear out the old input element
 setEventListener(inputElem, null);

 //getElement().replaceChild(newInputElem, inputElem);
 inputElem.replaceWith(newInputElem);

 // Sink events on the new element
 IEvent.sinkEvents(newInputElem, IEvent.getEventsSunk(inputElem));
 IEvent.sinkEvents(inputElem, 0);
 inputElem = newInputElem;

 // Setup the new element
 IEvent.sinkEvents(inputElem, sunkEvents);
 inputElem.id = _uid;

 formValue = _formValue;

 // Set the event listener
 if (isAttached()) {
   setEventListener(inputElem, this);
 }
}

{@inheritDoc} <p> Note: DirectionEstimator should be set before the label has any content; it's highly recommended to set it using a constructor. Reason: if the label already has non-empty content, this will update its direction according to the new estimator's result. This may cause flicker, and thus should be avoided.

void setDirectionEstimator(DirectionEstimator directionEstimator) {
 directionalTextHelper.setDirectionEstimator(directionEstimator);
}

Sets this object's browser element. UIObject subclasses must call this method before attempting to call any other methods, and it may only be called once.

void setElement(dart_html.Element elem) {
 assert (_element == null);
 this._element = elem;
}

void setEventListener(dart_html.Element e, EventListener listener) {

}

Sets the object's height. This height does not include decorations such as border, margin, and padding.

@param height the object's new height, in CSS units (e.g. "10px", "1em")

void setHeight(String height) {
 // This exists to deal with an inconsistency in IE's implementation where
 // it won't accept negative numbers in length measurements
 assert (extractLengthValue(height.trim().toLowerCase()) >= 0); // : "CSS heights should not be negative";
 Dom.setStyleAttribute(getElement(), "height", height);
}

void setHtml(SafeHtml html, Direction dir) {
 directionalTextHelper.setTextOrHtml(html.asString(), true, dir);

Sets the panel-defined layout data associated with this widget. Only the panel that currently contains a widget should ever set this value. It serves as a place to store layout bookkeeping data associated with a widget.

@param layoutData the widget's layout data

void setLayoutData(Object value) {
 this._layoutData = value;
}

Sets this widget's parent. This method should only be called by {@link Panel} and {@link Composite}.

     assert (isAttached()); // : "Failure of " + this.getClass().getName() + " to call super.onAttach()";
   }
 }
}

Sets the object's size, in pixels, not including decorations such as border, margin, and padding.

@param width the object's new width, in pixels @param height the object's new height, in pixels

void setPixelSize(int width, int height) {
 if (width >= 0) {
   setWidth(width.toString() + "px");
 }
 if (height >= 0) {
   setHeight(height.toString() + "px");
 }
}

Sets the object's size. This size does not include decorations such as border, margin, and padding.

@param width the object's new width, in CSS units (e.g. "10px", "1em") @param height the object's new height, in CSS units (e.g. "10px", "1em")

void setSize(String width, String height) {
 setWidth(width);
 setHeight(height);
}

Adds or removes a dependent style name by specifying the style name's suffix. The actual form of the style name that is added is:

getStylePrimaryName() + '-' + styleSuffix

@param styleSuffix the suffix of the dependent style to be added or removed @param add <code>true</code> to add the given style, <code>false</code> to

     remove it

@see #setStylePrimaryName(Element, String) @see #addStyleDependentName(String) @see #setStyleName(String, boolean) @see #removeStyleDependentName(String)

void setStyleDependentName(String styleSuffix, bool add) {
 setStyleName(getStylePrimaryName() + '-' + styleSuffix, add);
}

Adds or removes a style name. This method is typically used to remove secondary style names, but it can be used to remove primary stylenames as well. That use is not recommended.

@param style the style name to be added or removed @param add <code>true</code> to add the given style, <code>false</code> to

     remove it

@see #addStyleName(String) @see #removeStyleName(String)

void setStyleName(String style, bool add) {
 manageElementStyleName(getStyleElement(), style, add);
}

Sets the object's primary style name and updates all dependent style names.

@param style the new primary style name @see #addStyleName(String) @see #removeStyleName(String)

void setStylePrimaryName(String style) {
 setElementStylePrimaryName(getStyleElement(), style);
}

void setText(String text, Direction dir) {
 directionalTextHelper.setTextOrHtml(text, false, dir);
}

Checks or unchecks the check box, firing {@link ValueChangeEvent} if appropriate. <p> Note that this <em>does not</em> set the value property of the checkbox input element wrapped by this widget. For access to that property, see {@link #setFormValue(String)}

@param value true to check, false to uncheck; null value implies false @param fireEvents If true, and value has changed, fire a

     {@link ValueChangeEvent}

void setValue(bool val, [bool fireEvents = false]) {
 if (val == null) {
   val = false;
 }

 bool oldValue = getValue();
 inputElem.checked = val;
 inputElem.defaultChecked = val;
 if (val != oldValue && fireEvents) {
   ValueChangeEvent.fire(this, val);
 }
}

Sets the object's width. This width does not include decorations such as border, margin, and padding.

@param width the object's new width, in CSS units (e.g. "10px", "1em")

void setWidth(String width) {
 // This exists to deal with an inconsistency in IE's implementation where
 // it won't accept negative numbers in length measurements
 assert (extractLengthValue(width.trim().toLowerCase()) >= 0); // : "CSS widths should not be negative";
 Dom.setStyleAttribute(getElement(), "width", width);
}

Sinks a named event. Note that only {@link Widget widgets} may actually receive events, but can receive events from all objects contained within them.

@param eventTypeName name of the event to sink on this element @see com.google.gwt.user.client.Event

void sinkBitlessEvent(String eventTypeName) {
 Dom.sinkBitlessEvent(getElement(), eventTypeName);
}

This method is overridden so that any object can be viewed in the debugger as an HTML snippet.

@return a string representation of the object

String toString() {
 if (_element == null) {
   return "(null handle)";
 }
 return getElement().toString();
}

Removes a set of events from this object's event list.

@param eventBitsToRemove a bitfield representing the set of events to be

     removed from this element's event set

@see #sinkEvents @see com.google.gwt.user.client.Event

void unsinkEvents(int eventBitsToRemove) {
 Dom.sinkEvents(getElement(), Dom.getEventsSunk(getElement()) & (~eventBitsToRemove));
}
