MultiDisplay : choose specific display on boot

[weabow 6]

Hi there,

 

Closing myapp, I save in the ini the current screen with :

Screen.DisplayFromForm(self).Index (self is mainform).

 

It runs fine.

 

I'd like on boot to display the app on the same screen, using my Screen.DisplayFromForm(self).Index saved.

 

I can't see anywhere how to do that.

An idea ?

You cannot directly set a specific display. Instead you position the form so that it is shown on the desired display.

Thanks.

 

I tried to set Self.Left := -10000; but the form stays on the main screen.

It works as expected when I place the following code in FormCreate:

  var displayIndex := Screen.DisplayCount - 1;
  var display := Screen.Displays[displayIndex];
  SetBoundsF(display.Workarea.Left, display.Workarea.Top, Width, Height);

It runs perfectly ! Thanks a lot

Best to remember position instead of displaynumber (and windowmode (maximized or not)).

You also want to check if the position you set your form on still is visible, user could have disconnect a display for instance., so you can make sure your app is visible on startup.

Sure. After several checks, it works fine.

 

Thanks
