The following members return XtraMdiTabPage objects:
An XtraMdiTabPage object represents an MDI child form when the main MDI form is managed by the XtraTabbedMdiManager component.
You can access all tab pages with the XtraTabbedMdiManager.Pages collection. Use the XtraMdiTabPage.MdiChild property to access the MDI child form to which the tab page corresponds.
Tab pages support animated images (animated GIF files). You can specify images for pages via the XtraMdiTabPage.ImageOptions property. Animation starts automatically at runtime. To stop and then restart animation, use the XtraMdiTabPage.StopAnimation and XtraMdiTabPage.StartAnimation methods, respectively.
This example shows how to use an XtraTabbedMdiManager component to implement the tabbed interface in an MDI application.
The Load event handler of the main form (MDI Parent) binds an XtraTabbedMdiManager object to the form via the XtraTabbedMdiManager.MdiParent property.
The example creates a bar with the New command. An MDI child form created by this command is automatically displayed as a tab by the XtraTabbedMdiManager.
The XtraTabbedMdiManager.PageAdded event handler customizes tooltips of created tab pages.
