The most applications start with a main form, wich provides a genaral menu and a broadly application frame.
By interacting with the user in the life cycle of the application, dialogs are opened or core parts of the main window are changed.
For the application wizards the form Formulare/Start.form is the respective main window, with wich the applicatione can be startet (see Figure 1).

Fig. 305: Start Window at Execution
The main window (see Figure 2) in this example describes the partitioning of the form panels. This happens with the properties SidePanel and ToolBarPanel. Also the main window defines the entrys of the Menubar what picture will be on the left side.
As to see, the labels of the Menubar, the links and the
form title at execution (Figure 1) differ from them in the
preview(Figure 2). The labels in eva/3
forms and reports are evacuated in propertie files. E.g. the label
%Datei.text for the first entry in menubar will be localized by the file
Formulare/Start.properties >. This way the label Datei will be
found for the menu entry.

In addition the preview (Figure 2) differs from the execution (Figure 1) by the right button with application specifig user informations. They will be imported from the form Formulare/Optionen.form at opening ( WindowOpened ) (see Figure 3)
