This article describes the criteria Windows 95 uses to determine whether or
not the task bar is hidden when a window becomes full screen.
The criteria are as follows:
| • | The window is not a tool window.
|
| • | The window is either not maximized, or it is maximized but doesn't
have a caption.
|
| • | The window is being sized such that it covers the entire work area.
|
| • | The window is being sized such that one or more sides extend outside the
work area.
|
If all four conditions are met, a state bit is set on that window. Then,
whenever a window with that state bit (or a window that is owned by a
window with that state bit) is activated, the task bar is hidden to allow
the full-screen window to be displayed.
