WS_EX_COMPOSITED top-level constant

int const WS_EX_COMPOSITED

Paints all descendants of a window in bottom-to-top painting order using double-buffering.

Bottom-to-top painting order allows a descendent window to have translucency (alpha) and transparency (color-key) effects, but only if the descendent window also has the WS_EX_TRANSPARENT bit set. Double-buffering allows the window and its descendents to be painted without flicker. This cannot be used if the window has a class style of either CS_OWNDC or CS_CLASSDC.

Implementation

const WS_EX_COMPOSITED = 0x02000000;
