| data | | int data(Code) | | Used by native code as a pointer to the Qt widget.
|
| canBeFocusedByClick | | static boolean canBeFocusedByClick(Component component)(Code) | | |
| 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 Qt themes where a button, for example, may hava a pixmap
background.

| create | | abstract protected void create(QtComponentPeer parentPeer)(Code) | | Creates this component peer. This requires setting the data
field to point to a struct QtComponentData.
