Constrains the size of a window.
void prefsize(Int32 x, Int32 y)
SUBROUTINE PREFSI(x, y) INTEGER*4 x, y
The prefsize subroutine constrains the size, in pixels, of a window. With the prefsize subroutine, the applications programmer can prevent the user from resizing a window.
To remove constraints from a window, call the winconstraints subroutine immediately after calling the winopen subroutine. Calling winconstraints twice in a row also removes constraints from the window. Note that doing this nullifies all constraints, not just that of size.
If the prefsize subroutine call is followed by a call to the winopen subroutine, the window manager displays a window outline of the suggested size, allowing the user to position the window with the cursor.
If the prefsize subroutine call is followed by a call to the winconstraints subroutine, the current window is resized. The resizing occurs at the time of the winconstraints call; the prefsize subroutine has no effect on the current window until that time.
Note: This subroutine cannot be used to add to a display list.
|x||Specifies the width of the window in pixels.|
|y||Specifies the height of the window in pixels.|
