Sets the size and screen position of a QuickWin window.
#include <io.h>
int _wsetsize( int wfh, struct _wsizeinfo *wsize );
| wfh | File handle to a QuickWin window | |
| wsize | Pointer to a _wsizeinfo structure |
The _wsetsize function sets the size and position of a QuickWin window. This routine is used only in QuickWin programs; it is not part of the Windows API. For full details about QuickWin, see Chapter 8 of Programming Techniques (in the Microsoft C/C++ version 7.0 documentation set).
The wsize argument points to a _wsizeinfo structure (declared in IO.H) containing the new size and position information. The structure contains a _type field that can have one of the following values:
| Value | Meaning |
| _WINSIZEMIN | Minimize the window |
| _WINSIZEMAX | Maximize the window |
| _WINSIZRESTORE | Restore a previously minimized window |
| _WINSIZECHAR | Use character coordinates for the window size |
If the type is _WINSIZECHAR, you must supply the _x, _y, _h, and _w values in the remainder of the structure. They specify the upper-left corner and the height and width of the window (in characters).
If successful, _wsetsize returns 0. A return value of –1 indicates an error.
