Class IzCCombo0
- All Implemented Interfaces:
org.eclipse.swt.graphics.Drawable
CCombo was written to work around certain limitations in the native combo box. Specifically, on win32, the height of a CCombo can be set; attempts to set the height of a Combo are ignored. CCombo can be used anywhere that having the increased flexibility is more important than getting native L&F, but the decision should not be taken lightly. There is no strict requirement that CCombo look or behave the same as the native combo box.
Note that although this class is a subclass of Composite
, it does not make sense to add children to it, or set a layout on it.
- Styles:
- BORDER, READ_ONLY, FLAT, LEAD, LEFT, CENTER, TRAIL, RIGHT
- Events:
- DefaultSelection, Modify, Selection, Verify
