The SelectObject function selects an object into the specified device context. The new object replaces the previous object of the same type.
HGDIOBJ SelectObject(
HDC hdc, |
// handle of device context |
HGDIOBJ hgdiobj |
// handle of object |
); |
Object |
Functions |
Bitmap |
CreateBitmap, CreateBitmapIndirect, CreateCompatibleBitmap, CreateDIBitmap, CreateDIBSection |
(Bitmaps can be selected for memory device contexts only, and for only one device context at a time.) | |
Brush |
CreateBrushIndirect, CreateDIBPatternBrush, CreateDIBPatternBrushPt, CreateHatchBrush, CreatePatternBrush, CreateSolidBrush |
Font | |
Pen | |
Region |
CombineRgn, CreateEllipticRgn, CreateEllipticRgnIndirect, CreatePolygonRgn, CreateRectRgn, CreateRectRgnIndirect |
If the selected object is not a region and the function succeeds, the return value is the handle of the object being replaced. If the selected object is a region and the function succeeds, the return value is one of the following values:
Value |
Meaning |
SIMPLEREGION |
Region consists of a single rectangle. |
COMPLEXREGION |
Region consists of more than one rectangle. |
NULLREGION |
Region is empty. |
If an error occurs and the selected object is not a region, the return value is NULL. Otherwise, it is GDI_ERROR.
This function returns the previously selected object of the specified type. An application should always replace a new object with the original, default object after it has finished drawing with the new object.
An application cannot select a bitmap into more than one device context at a time.
