I'm using Qt Creator.

Here's the ui code:

Also, I'm in north central Florida, so if I don't get back with you right away, we've lost power :)

Are you sure it's not your stacked widget that is showing the wrong widget ?

That said, I would split that QMainWindow in smaller widgets to improve encapsulation.

[Bob K.]

The stacked widget is not displaying any widgets.

I'm not sure what you mean by splitting the main window into smaller widgets? The main window contains a tab widget, which is where all the data will be displayed.

The dock widget contains a list of database entries. Once an entry is selected, any data manipulation will take place in the tab widget. That's why I wanted dock widget to be moveable.

[ChrisW67]

Your UI works correctly on Linux, Qt 6.3.1.

The dock widget has no controls to navigate between the pages, so you only see pageSession (the currentIndex).

Are you able to post an image of what you see?
Are you able to try a different Qt version?

@Bob-K
The information about Qt Creator is not relevant. That is an IDE to develop your code. What exact version of Qt do you use/your application is configured to build with?

[Bob K.]

Qt 6.3.1 (MSVC 2019, x86_64)

[Bob K.]

Is this being looked at, or have I done something wrong?

[Bob K.]

Now working!

[ChrisW67]

@Bob-K No, nothing wrong. This is not paid Qt support though. For my part life got in the way.

Good to hear that you fixed the problem. Where was the issue?

[Bob K.]

I'm not sure. I did update Qt, so perhaps that did the trick. Anyway, it's working.
