I am using PB 2019 R3 2703 Trail.

I am trying to switch an MDI application to the RibbonBar. I start the application and select a window from the Ribbonbar, it is called but it is not visible. With the old menu everything works.
The call in the program code is done with "opensheet" or "opensheetwithparm". If the call is made with "open" the window is displayed.

Hi Ewald;

  That could happen if you are not resizing MDI_1 object class to account for RibbonBar correctly within the MDI frame. The PB help has more information & example code to use for this.  HTH

Hello Chris,

Thanks for your support!

Do you mean the "resize event" in the MDI? I have copied this from the example. The ribbonbar is displayed correctly, also my resizing the window.

Or could you describe your hint a bit more detailed.

Hi Ewald;

I was referring to the Resize event of the MDI Frame window that resizes the MDI_1 object. If this is not done properly, no sheet will appear as sheets are attached inside of MDI_1 when opened.

A quick test would be to remove the ribbonbar object and if the sheets now open OK, then the likely issue is the RibbonBar object & the way it's placed inside the MDI Frame or how MDI_1 is moved & resized around the Ribbon Bar's space inside the MDI Frame.

Regards... Chris
