Retrieving graphics objects selected into a DC!

Felt the need to retrieve current brush or pen or palette selected into a DC? Sometime back a friend of mine asked me this question, as an answer I gave him a better solution, but the question was a valid one!

So are there any windows api’s that helps us in the regard? Well the answer is yes, use GetCurrentObject and GetObject in tandem to retrieve details of graphics object selected into a dc.

GetCurrentObject signature

[sourcecode language=’cpp’]HGDIOBJ GetCurrentObject( HDC hdc, // handle to DC
UINT uObjectType // object type
);[/sourcecode]

Lookup MSDN for possible values of uObjectType.

GetObject signature

[sourcecode language=’cpp’]int GetObject( HGDIOBJ hgdiobj, // handle to graphics object
int cbBuffer, // size of buffer for object information
LPVOID lpvObject // buffer for object information
);[/sourcecode]

Lookup MSDN for possible values of lpvObject in GetObject. Here is an example of how to use these functions!

[sourcecode language=’cpp’]// Use GetCurrentObject to get current brush selected in to a DC
HBRUSH hCurrentDCBrush = GetCurrentObject( hDC, OBJ_BRUSH );

// Get brush details
LOGBRUSH lCurrentBrushDetails = { 0 };
GetObject( hCurrentDCBrush, sizeof( lCurrentBrushDetails ), &lCurrentBrushDetails );[/sourcecode]
