Inherited Members

controlId int controlId(): The control's command identifier (the hMenu child id at creation).
setText void setText(string text): Set the control's text.
getText string getText(): Get the control's text.
setFont void setFont(HFONT font): Assign a font to the control and request a repaint.
getPreferredSize Size getPreferredSize(): A reasonable default preferred size; override per control type.
processCommand bool processCommand(ushort notificationCode): Handle a WM_COMMAND notification routed from the parent.
processNotify bool processNotify(NMHDR* header): Handle a WM_NOTIFY notification routed from the parent. Return true if it was handled. The default does nothing.
subclass void subclass(): Install a subclass window procedure so the control can intercept its own messages (for example, swallowing the Enter key in a text field). Idempotent. Subclasses override processSubclassed to do the work.
processSubclassed bool processSubclassed(UINT msg, WPARAM wParam, LPARAM lParam, LRESULT result): Intercept a message while subclassed. Set result and return true to consume the message; return false to let default processing continue.
