Widget

This class is the abstract superclass of all user interface objects. Widgets are created, disposed and issue notification to listeners when events occur which affect them. <dl> <dt><b>Styles:</b></dt> <dd>(none)</dd> <dt><b>Events:</b></dt> <dd>Dispose</dd> </dl> <p> IMPORTANT: This class is intended to be subclassed <em>only</em> within the SWT implementation. However, it has not been marked final to allow those outside of the SWT development team to implement patched versions of the class in order to get around specific limitations in advance of when those limitations can be addressed by the team. Any class built using subclassing to access the internals of this class will likely fail to compile or run between releases and may be strongly platform specific. Subclassing should not be attempted without an intimate and detailed understanding of the workings of the hierarchy. No support is provided for user-written classes which are implemented as subclasses of this class. </p>

Constructors

this this(): Prevents uninitialized instances from being created outside the package.
this this(Widget parent, int style): Constructs a new instance of this class given its parent and a style value describing its behavior and appearance. <p> The style value is either one of the style constants defined in class <code>SWT</code> which is applicable to instances of this class, or must be built by <em>bitwise OR</em>'ing together (that is, using the <code>int</code> "|" operator) two or more of those <code>SWT</code> style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses. </p>

Members

Functions

_addListener void _addListener(int eventType, Listener listener): Undocumented in source. Be warned that the author may not have intended to support it.
addDisposeListener void addDisposeListener(DisposeListener listener): Adds the listener to the collection of listeners who will be notified when the widget is disposed. When the widget is disposed, the listener is notified by sending it the <code>widgetDisposed()</code> message.
addListener void addListener(int eventType, Listener listener): Adds the listener to the collection of listeners who will be notified when an event of the given type occurs. When the event does occur in the widget, the listener is notified by sending it the <code>handleEvent()</code> message. The event type is one of the event constants defined in class <code>SWT</code>.
cellDataProc void cellDataProc(GtkTreeViewColumn* tree_column, GtkCellRenderer* cell, GtkTreeModel* tree_model, GtkTreeIter* iter, void* data): Undocumented in source. Be warned that the author may not have intended to support it.
checkOpen void checkOpen(): Undocumented in source. Be warned that the author may not have intended to support it.
checkOrientation void checkOrientation(Widget parent): Undocumented in source. Be warned that the author may not have intended to support it.
checkParent void checkParent(Widget parent): Throws an exception if the specified widget can not be used as a parent for the receiver.
checkSubclass void checkSubclass(): Checks that this class can be subclassed. <p> The SWT class library is intended to be subclassed only at specific, controlled points (most notably, <code>Composite</code> and <code>Canvas</code> when implementing new widgets). This method enforces this rule unless it is overridden. </p><p> <em>IMPORTANT:</em> By providing an implementation of this method that allows a subclass of a class which does not normally allow subclassing to be created, the implementer agrees to be fully responsible for the fact that any such subclass will likely fail between SWT releases and will be strongly platform specific. No support is provided for user-written classes which are implemented in this fashion. </p><p> The ability to subclass outside of the allowed SWT classes is intended purely to enable those not on the SWT development team to implement patches in order to get around specific limitations in advance of when those limitations can be addressed by the team. Subclassing should not be attempted without an intimate and detailed understanding of the hierarchy. </p>
checkWidget void checkWidget(): Throws an <code>SWTException</code> if the receiver can not be accessed by the caller. This may include both checks on the state of the receiver and more generally on the entire execution context. This method <em>should</em> be called by widget implementors to enforce the standard SWT invariants. <p> Currently, it is an error to invoke any method (other than <code>isDisposed()</code>) on a widget that has had its <code>dispose()</code> method called. It is also an error to call widget methods from any thread that is different from the thread that created the widget. </p><p> In future releases of SWT, there may be more or fewer error checks and exceptions may be thrown for different reasons. </p>
createHandle void createHandle(int index): Undocumented in source. Be warned that the author may not have intended to support it.
createWidget void createWidget(int index): Undocumented in source. Be warned that the author may not have intended to support it.
deregister void deregister(): Undocumented in source. Be warned that the author may not have intended to support it.
destroyWidget void destroyWidget(): Undocumented in source. Be warned that the author may not have intended to support it.
dispose void dispose(): Disposes of the operating system resources associated with the receiver and all its descendants. After this method has been invoked, the receiver and all descendants will answer <code>true</code> when sent the message <code>isDisposed()</code>. Any internal connections between the widgets in the tree will have been removed to facilitate garbage collection. <p> NOTE: This method is not called recursively on the descendants of the receiver. This means that, widget implementers can not detect when a widget is being disposed of by re-implementing this method, but should instead listen for the <code>Dispose</code> event. </p>
error void error(int code): Undocumented in source. Be warned that the author may not have intended to support it.
filterProc int filterProc(XEvent* xEvent, GdkEvent* gdkEvent, void* data): Undocumented in source. Be warned that the author may not have intended to support it.
filters bool filters(int eventType): Undocumented in source. Be warned that the author may not have intended to support it.
fixMnemonic char[] fixMnemonic(String str, bool replace): Undocumented in source. Be warned that the author may not have intended to support it.
fixMnemonic char[] fixMnemonic(String str): Undocumented in source. Be warned that the author may not have intended to support it.
fixedMapProc int fixedMapProc(GtkWidget* widget): Undocumented in source. Be warned that the author may not have intended to support it.
fixedSizeAllocateProc void fixedSizeAllocateProc(GtkWidget* widget, GtkAllocation* allocationPtr): Undocumented in source. Be warned that the author may not have intended to support it.
fontHeight int fontHeight(PangoFontDescription* font, GtkWidget* widgetHandle): Undocumented in source. Be warned that the author may not have intended to support it.
getData Object getData(String key): Returns the application defined property of the receiver with the specified name, or null if it has not been set. <p> Applications may have associated arbitrary objects with the receiver in this fashion. If the objects stored in the properties need to be notified when the widget is disposed of, it is the application's responsibility to hook the Dispose event on the widget and do so. </p>
getData Object getData(): Returns the application defined widget data associated with the receiver, or null if it has not been set. The <em>widget data</em> is a single, unnamed field that is stored with every widget. <p> Applications may put arbitrary objects in this field. If the object stored in the widget data needs to be notified when the widget is disposed of, it is the application's responsibility to hook the Dispose event on the widget and do so. </p>
getDataStr String getDataStr(String key): Undocumented in source. Be warned that the author may not have intended to support it.
getDataStr String getDataStr(): Undocumented in source. Be warned that the author may not have intended to support it.
getDisplay Display getDisplay(): Returns the <code>Display</code> that is associated with the receiver. <p> A widget's display is either provided when it is created (for example, top level <code>Shell</code>s) or is the same as its parent's display. </p>
getListeners Listener[] getListeners(int eventType): Returns an array of listeners who will be notified when an event of the given type occurs. The event type is one of the event constants defined in class <code>SWT</code>.
getName String getName(): Undocumented in source. Be warned that the author may not have intended to support it.
getNameText String getNameText(): Undocumented in source. Be warned that the author may not have intended to support it.
getStyle int getStyle(): Returns the receiver's style information. <p> Note that the value which is returned by this method <em>may not match</em> the value which was provided to the constructor when the receiver was created. This can occur when the underlying operating system does not support a particular combination of requested styles. For example, if the platform widget used to implement a particular SWT widget always has scroll bars, the result of calling this method would always have the <code>SWT.H_SCROLL</code> and <code>SWT.V_SCROLL</code> bits set. </p>
gtk_activate int gtk_activate(GtkWidget* widget): Undocumented in source. Be warned that the author may not have intended to support it.
gtk_button_press_event int gtk_button_press_event(GtkWidget* widget, GdkEventButton* event): Undocumented in source. Be warned that the author may not have intended to support it.
gtk_button_release_event int gtk_button_release_event(GtkWidget* widget, GdkEventButton* event): Undocumented in source. Be warned that the author may not have intended to support it.
