Hello,

I am trying to add RibbonBar to my MDI application and following tutorial: https://docs.appeon.com/pb2022/pbug/Replace_an_Application_Menu_with_a_RibbonBar.html#d0e25044

 I am using PB 2022 Build #1892

After changing MDI menu to empty one, I add ribbon control and adding the code to resize event. Unfortunately the code shown in Tutorial (see the link above) is not working as compiler throws error about missing mdi_1 object at lines below:

//resize mdi_1 based on RibbonBar
mdi_1.move (0, rbb_1.height + newheight - this.workspaceheight())
mdi_1.resize (newwidth, newheight - rbb_1.height - ( newheight - this.workspaceheight()))

I downloaded the Ribbon Application example and saw, that mdi_1 corresponds to MDIClient type which is missing on my w_mdi window.

As a result, opening sheets with openshee(..) does not work property as windows are not shown within MDI space.

Is there a way to add MDIClient object to MDI window?

Thanks!

BR,

D.
