SetWindowExtEx
The SetWindowExtEx function sets the horizontal and vertical extents of the window for a device
context by using the specified values.
BOOL SetWindowExtEx(
HDC hdc,
| // handle of device context
| int nXExtent,
| // new horizontal window extent
| int nYExtent,
| // new vertical window extent
| LPSIZE lpSize
| // original window extent
| );
|
|
Parameters
hdc
Identifies the device context.
nXExtent
Specifies the window's horizontal extent in logical units.
nYExtent
Specifies the window's vertical extent in logical units.
lpSize
Points to a SIZE structure. The previous window extents (in logical units) are placed in this
structure. If lpSize is NULL, nothing is returned.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
Remarks
When the following mapping modes are set, calls to the SetWindowExtEx and SetViewportExtEx functions are ignored:
- MM_HIENGLISH
- MM_HIMETRIC
- MM_LOENGLISH
- MM_LOMETRIC
- MM_TEXT
- MM_TWIPS
When MM_ISOTROPIC mode is set, an application must call the SetWindowExtEx function before calling SetViewportExtEx.
