Class XbpTabPage() Foundation
Class function of the XbpTabPage class.
The XbpTabPage class provides objects that manage tabbed dialogs (index tabs). These are dialog elements that look like index cards:
Any dialog element can be placed within a tab page. The tab is used to activate the page of the XbpTabPage object which brings the page to the foreground. All dialog elements available within the page then become visible. The position and width of the tab are defined by the instance variables :preOffset and :postOffset. Numeric values specifying the offset for the left and right edge of the tab (as a percent of the total width) must be assigned to the instance variables before the :create() method is called.
Two or more XbpTabPage objects are generally displayed at the same position in the window with different positions for each of their tabs. This allows all the tabs to be visible while only one page is active. When a tab is clicked, the corresponding page is brought to the foreground making its dialog elements available. This process is accomplished using the methods :maximize() and :minimize().
The instance variables in this group configure system resources. If changes are made to the default values, they must be made before the :create() method is executed or :configure() must be called to activate the changes.
