Usage Notes
- You cannot hide the canvas that contains the current item.
- You can hide a window that contains the current item.
Note: In some operating systems, it is possible to hide the only window in the form.
- When you use GET WINDOW PROPERTY to determine window visibility, Oracle Forms
uses the following rules:
- A window is considered visible if it is displayed, even if it is entirely
hidden behind another window.
- A window that has been iconified (minimized) is reported as visible to the
operator because even though it has a minimal representation, it is still
mapped to the screen.
- When you use GET VIEW PROPERTY to determine canvas visibility, Oracle Forms
uses the following rules:
- A view is reported as visible when it is a) in front of all other views
in the window or b) only partially obscured by another view.
- A view is reported as not visible when it is a) a stacked view that is behind
the content view in the window or b) completely obscured by a single stacked
view. Note that a view is reported as visible even if it is completely
obscured by a combination of two or more stacked views.
- The display state of the window does not affect the setting of the canvas
VISIBLE property. That is, a canvas may be reported visible even if the window
in which it is displayed is not currently mapped to the screen.
