Retrieve the system bitmap object by identifier.

This function retrieves and returns the system bitmap object by its identifier id for the specified window hWnd.

Parameters
hWndThe handle to the window.
idThe identifier of the system bitmap object, can be one of the following values: 
- SYSBMP_RADIOBUTTON\n
- SYSBMP_CHECKBUTTON\n
- SYSBMP_BGPICTURE\n

◆ GetSystemBitmapEx()

const BITMAP *GUIAPI GetSystemBitmapEx ( const char *  rdr_name,
const char *  id 
)
inlinestatic

Retrieve the system bitmap object by identifier.

This function retrieves and returns the system bitmap object by the renderer name rdr_name and the identifier id. This function returns a BITMAP object which complies which is compliant to HDC_SCREEN.

Parameters
rdr_nameThe renderer name.
idThe identifier of the system bitmap object, can be one of the following values:

Definition at line 9203 of file window.h.

◆ GetSystemBitmapEx2()

const BITMAP *GUIAPI GetSystemBitmapEx2 ( HDC  hdc,
const char *  rdr_name,
const char *  id 
)

Retrieve the system bitmap object by identifier.

This function retrieves and returns the system bitmap object specified by the renderer name rdr_name and the identifier id. This function returns the BITMAP object which is compliant to the specified device context hdc.

Parameters
hdcThe handle to the device context.
rdr_nameThe renderer name.
idThe identifier of the system bitmap object, can be one of the following values:
  • SYSBMP_RADIOBUTTON
  • SYSBMP_CHECKBUTTON
  • SYSBMP_BGPICTURE
    Returns
    The pointer to the system bitmap object.
    Note
    Since 5.0.0, if you use the compositing schema, a main window may use a private surface which is not compliant to the screen surface. Under this situation, you should use this function to load the system bitmap object instead of using GetSystemBitmapEx.
