WinDeactivate
Declaration:
void
WinDeactivate
(WINDOW *
w
)
Category(ies):
Windows
Description:
Deactivate a window (changes its border to single-line unless full screen).
Inputs:
w
— WINDOW struct of a previously opened window.
Outputs:
None
Assumptions: WinDeactivate
is really only needed if an app has multiple windows. The
purpose is to provide a visual clue to the user that a particular window has
lost the current focus and that another window (which will be activated with
WinActivate
) has received the focus. When
WinActivate
is called, the
window with the current focus (the last one to do a
WinActivate
) is
automatically deactivated with
WinDeactivate
and so it is not necessary to
explicitly call
WinDeactivate
.
Side Effects:
None

Example:
WINDOW win1, win2;
if (WinOpen(&win2, MakeWinRect(5,5,70,50), WF_ROUNDEDBORDER|WF_TTY)) {
WinActivate( &win2 ); /* just to draw the border */
if (WinOpen(&win1, MakeWinRect(75,5,140,50), WF_TTY)) {
WinActivate( &win1 ); WinClr( &win1 );
WinStr( &win1, "ACTIVE\nWINDOW" );
GKeyIn( NULL, 0 );
WinClr( &win1 ); WinStr( &win1, "NOT\nACTIVE");
WinDeactivate( &win1 );
WinStr( &win2, "NO WINDOWS\nACTIVE" );
GKeyIn( NULL, 0 );
WinClose( &win2 );
}
WinClose( &win1 );
}
