Windows are output areas for all output data. You can set the size and position of a window graphically in the Form Painter. There aremain windows and secondary windows. The most important difference is that the output in a main window can cover several pages.
After you created a form, a main window already exists on the first page.
Apage exists on which you want to create a window.
If you create the window in the Form Painter using the context menu, you can use the mouse to position it immediately.
For each page you can indicate only one main window.
You can see the window in the Form Painter and in the tree structure. You can always change the specification of the main window or of a secondary window.
