Rect | |
uType | The control type, e.g. DFC_CAPTION. |
uState | The control state, e.g. DFCS_CAPTIONCLOSE (close button). |
Function result
False on failure.Description
A window frame includes these components (uType):
- title bar (DFC_CAPTION)
- menu bar (DFC_MENU)
- popup menus (DFC_POPUPMENU)
- scrollbars (DFC_SCROLL)
Window managers do not normally allow the user to paint the components for a window frame, and do not supply a DC for that purpose.
The available features depend on the window manager for the platform, and the capabilities for the widgetset.
