COleControl::GetControlFlags

virtual DWORD GetControlFlags( );

Return Value

An ORed combination of the flags in the ControlFlags enumeration:

enum ControlFlags {
   fastBeginPaint = 0x0001,
   clipPaintDC = 0x0002,
   pointerInactive = 0x0004,
   noFlickerActivate = 0x0008,
   windowlessActivate = 0x0010,
   canOptimizeDraw = 0x0020,
};

Remarks

Override this function to specify the control flag settings. By default, GetControlFlags returns fastBeginPaint | clipPaintDC.

fastBeginPaint

If set, uses a begin-paint function tailored for OLE controls instead of the BeginPaint API (set by default).

clipPaintDC

If not set, disables the call to IntersectClipRect made by COleControl and gains a small speed advantage. If you are using windowless activation, the flag has no effect.

pointerInactive

If set, provides mouse interaction while your control is inactive by enabling COleControl's implementation of the IPointerInactive interface, which is disabled by default.

noFlickerActivate

If set, eliminates extra drawing operations and the accompanying visual flicker. Use when your control draws itself identically in the inactive and active states. If you are using windowless activation, the flag has no effect.

windowlessActivate

If set, indicates your control uses windowless activation.

canOptimizeDraw

If set, indicates that the control will perform optimized drawing, if the container supports it.
