Two dialog of qt and parent child relationship | border issue

Question

Hi

I had similar question asked here. It was solved as per my understanding, but it seems I missed an important detail.

When parent child relation is set and made child dialog move independently, I could see child dialog has only right and bottom border, not other two borders. How to get rid off two shown borders?

Answer 1

To remove unwanted borders from a child dialog in Qt, especially when using parent-child relationships, you can try customizing the window flags. For your case, try setting the window flags like this:

childDialog->setWindowFlags(Qt::Dialog | Qt::FramelessWindowHint);

This removes all the borders. If you want to keep specific ones or have better control, you can use Qt::CustomizeWindowHint along with other flags.

Also, ensure that the childDialog isn’t using any stylesheet that could override border settings.

Let me know if you need help with an example implementation.

Answer 2

Windows flag helped me a lot to get rid off the border. But it then makes it impossible to move the window.

How to achieve this
