Particularities of the Attributes .sensitive and .visible
Unlike the other object attributes, the attributes .visible and .sensitive get their final shape only in connection with the object hierarchy. This is because the corresponding attributes of the related parent object have a decisive influence on them. This means that an object can only be visible if itself and its parent are visible. The same applies to selectivity.
Remark
The statement Window.visible := true does the following:
- If the window is visible, it will emerge to the foreground after the statement is executed, i.e. it will become the foremost window.
- If the window is invisible, it will appear on the screen after the statement is executed.
