You cannot specify the full name of file to open (".WDW" file).

<Parameter 1>: Type of value sent to the window (optional)

First parameter that will be passed to the "Global declarations" event of the window to open. This parameter is passed by value and is considered a variable global to the window.

This parameter cannot correspond to an array variable (arrays can only be passed by reference).

Remarks

Parameters passed to the window to open

The parameters are retrieved in the event "Global declarations" associated with the window. The first line of code of this event must correspond to the following line:

PROCEDURE <Window> (<Parameter 1> [, ... [, <Parameter N>]])

where:

<Window > must correspond to the name of the window.
<Parameter N> must correspond to the parameters expected. Caution: These parameters are passed by value and not by reference.

Window opening mode

The window is opened in non-modal mode:

the opened window becomes the current window.
after the window opening, the processes following the call to OpenMobileWindow in the parent window are run.
the user will have the ability to click one of the parent windows of opened window.
The controls found in the parent windows cannot be accessed by the user as long as a child window is opened.

Limitations

OpenMobileWindow must not be called in the event "Initializing" associated with the project.
OpenMobileWindow must not be called in the event "Closing" of a child window.

Closing a window

A window opened with OpenMobileWindow can be closed with Close (without parameters) from any event associated with the window or a control in the window.

Title of the window to be opened

By default, the window title is the one defined in the editor (in the "General" tab of the description window).

To modify the window title, use NextTitle or CurrentTitle.

Versions 25 and later

Application in the background: Specific case from Android 10

From Android 10, it is no longer possible to open a window when the application is in the background.

OpenMobileWindow can open a window. If this function is used while the application is in the background, a fatal error will occur.

Tips:

It is possible to determine if the application is in the background using InBackgroundMode.
If an application needs to interact with the user while it is in the background, the solution is to display a notification (via the Notification type). The application will be brought back to the foreground when the notification is clicked, if the ActivateApplication property is set to True. You can also open a window from the procedure passed to the ActionClick property.
