| data | | int data(Code) | | Used by native code as a pointer to the Gtk widget.
|
| canHavePixmapBackground | | protected boolean canHavePixmapBackground()(Code) | | Decides whether it is possible for this component to have a pixmap background (i.e. a non solid color).
We allow all components except Window, Frame, Dialog, Panel and Canvas to have pixmaps as the user
can, and typically does, override the paint for these components. Thus update can be called which will clear
the background with a solid color for these components. However, we would still like to have support for Gtk
themes where a button, for example, may hava a pixmap background.
|
| create | | abstract protected void create()(Code) | | Creates this component peer. This requires setting the data field to point to a
struct GComponentData.
|
| createImage | | public Image createImage(int width, int height)(Code) | | |
| dispose | | public void dispose()(Code) | | |
| getLocationOnScreen | | native public Point getLocationOnScreen()(Code) | | |
| hide | | native void hide()(Code) | | Hides this widget
|
| isFocusTraversable | | public boolean isFocusTraversable()(Code) | | |
| postMouseEvent | | void postMouseEvent(int id, long when, int modifiers, int x, int y, int clickCount, boolean popupTrigger, int nativeEvent)(Code) | | |
| postPaintEvent | | void postPaintEvent(int x, int y, int width, int height)(Code) | | Posts a paint event for this component. This is called when an area of the component is exposed.
The area that needs to be painted is specified by the parameters.
|
