AndroidiPhone/iPadIOS Widget

Finding out the value returned by a child window

In the mobile applications, the windows are opened by OpenMobileWindow (or OpenChild) instead of Open up.
You can get the value returned by a child window in the "Close a child window" event of the window that opened it (the one that called OpenMobileWindow or OpenChild).
For example:
  • In the closing code of the child window, Farm is used to return a parameter: 
    Close("", MyParameter)
  • The name of the child window as well as the returned value can be retrieved in the "Close a child window" event of the calling window, using the MyChildWindow keyword: 
    // Close a child window
NameChildWindow = MyChildWindow.Name
ValueChildWindow = MyChildWindow.ReturnedValue

Limits

The ReturnedValue property is applied:
  • WINDEVAndroidWidget Android Java windows,
  • WEBDEV - Código Servidor pages,
  • WINDEVAndroidJava options in Radio Button controls.
  • WINDEV internal windows only if they are opened with Open up.
  • WINDEVReportes y ConsultasiPhone/iPadIOS Widget reports.
  • WINDEVReportes y ConsultasiPhone/iPadIOS Widget internal reports (in read-only).
  • WEBDEV - Código Navegador popups used via a Popup Combo Box control.
