Full Transparency Support

F-IN-BOX allows you to create applications that use transparent Flash movies, including windows with non-rectangular shapes and layered effects.
This enables building modern user interfaces where Flash is combined with native application logic.

Transparency is implemented through layered windows (WS_EX_LAYERED), which let Flash content blend with custom backgrounds or the desktop.

Example

HFPC hFPC = FPC_LoadRegisteredOCX();
 
RECT rc = { 0, 0, 640, 480 };
 
HWND hwndFlashPlayerControl = 
   FPC_CreateWindow(hFPC, 
                    WS_EX_LAYERED, 
                    NULL, 
                    WS_POPUP | WS_VISIBLE, 
                    nLeft, 
                    nTop, 
                    nWidth, 
                    nHeight, 
                    hWnd, 
                    NULL, 
                    NULL, 
                    NULL);
 
ShowWindow(hwndFlashPlayerControl, SW_SHOW);
UpdateWindow(hwndFlashPlayerControl);

With this approach, Flash movies can be used as part of custom-shaped forms, enabling translucent effects and non-standard UI designs.
