Widget->show() place widget to top left corner (not on the top of mainwindow)

[Zlatomir]

I'm not sure that i understand your code, but:
this:

this->about = new DialogAbout(parent);

this->about = new DialogAbout(parent);

To copy to clipboard, switch view to plain text mode 

shouldn't be like this?

this->about = new DialogAbout(this);

this->about = new DialogAbout(this);

To copy to clipboard, switch view to plain text mode

Hi,

it doesn't help. Any other advices ? Thanks

[Zlatomir]

If you can't post your code, please make a small project that has that behavior and post it.

No problem. See attachment.

Your form should inherit from QDialog, so it can be a top-level window, have a parent and be centered on top of that parent.

And as Zlatomir said, you should pass this to its constructor:

this->form = new Form(this);

this->form = new Form(this);

To copy to clipboard, switch view to plain text mode

Hi,

I think (parent) is OK. If I use your proposals then my mainwindow is mixed with form widget. Did you try it you just assume it should be in that way? Thanks

If you make it a dialog it works like you want (or at least like i think you want)

And i don't recommend to make the Form member in MainWindow (check the code)
You can emit a signal (a MainWindow signal) when member button is clicked, and connect that with the show() slot of your Form (that's what on_bla_bla slots do with auto-connect, or you can manualy connect them)

Hmm, I think this doesn't solve my situation. I need to mention I use 5 same widgets which I show with show() method and only 1 of them make a problem (is displayed at the top left corner). With my attachment I would like to show you whats the problem. It's rather strange for me why this happens because I use it is same way.
