- Modal windows
- Non-modal windows
- MDI windows
5. Modal, non-modal or MDI windows
The applications created with WINDEV can use several types of windows (and mix each one of these types). Modal windows A modal window is opened in the foreground of the application and it locks the access to the other windows that are already opened (if any). In most cases, modal windows are used as: - main windows of an application,
- dialog boxes whose validation triggers an action.
With WINDEV, when a modal window is opened, a gray shadow appears on the windows displayed in the background: it is the DDW feature or Dim Disabled Windows. Non-modal windows A non-modal window is opened in parallel with other application windows. Each window remains accessible. In most cases, non-modal windows are used: - as tool palettes,
- as dialog boxes that affect the main window when modified.
In this example, each description window of a chair opens the description window of another chair. All open windows remain accessible. MDI windows In a Multiple Document Interface (MDI) application, all the windows of the application are displayed in one main window: the MDI parent window. Two types of windows can be found in the MDI applications: | | |
| MDI parent window: All the other application windows are displayed in this window. This window allows the user to handle the main menu of the application. | | MDI child window: Application window displayed in the parent window. The user will be able to type information in these windows. | | |
