The GetClipBox function retrieves the dimensions of the tightest bounding rectangle that can be drawn around the current visible area on the device. The visible area is defined by the current clipping region or clip path, as well as any overlapping windows.
int GetClipBox(
| HDC hdc, | // handle of the device context |
| LPRECT lprc | // address of structure with rectangle |
| ); |
Parameters
hdc
Identifies the device context.
lprc
Points to a RECT structure that is to receive the rectangle dimensions.
Return Values
If the function succeeds, the return value specifies the clipping box's complexity and can be any one of the following values:
| Value | Meaning |
| NULLREGION | Region is empty. |
| SIMPLEREGION | Region is a single rectangle. |
| COMPLEXREGION | Region is more than one rectangle. |
| ERROR | An error occurred. |
GetClipBox returns logical coordinates based on the given device context.
