Hmm, not good! But I don't think I follow: yes you show some "invisibility", but getOpenFileNames() etc. are dialogs which pop up. They would not have your "button furniture", what you show is your own window/dialog, I don't see what you press to cause the "open files" dialog to pop up? I don't see how what you are showing demonstrates getOpenFileNames() is even being called?

@JonB I can show you if you give me your skype or other communication tool.

@Rudo1
No, we answer questions in the forum here, not personally.
You could explain how come QFileDialog::get...() pop up a file selector dialog while what you show seemingly has no popup dialog but instead shows a blank area in an existing widget. And you could also explain how FirstWindow::on_action1_triggered() gets called from what you show.

@JonB In my UI I have seperator, and on_action1_triggered is action of it, when I click to seperator I must have open QFileDialog and select .mp4 file in list. I try it in new project and it works, but in my project it doesn't work.

Then I have no idea how what you describe relates to the screenshot you show, which has no popup QFileDialog.

If you say it works in a standalone program but not your code then you have the answer: you are presumably doing something wrong in your code. Reduce/build it up compared to a standalone example which works to find out what. Have you yet even verified it does call your FirstWindow::on_action1_triggered() at all?

[Rudo1]

@JonB Okay, thanks for your time, if I will solve this problem, I will write about it.

@Rudo1
I would start by placing a qDebug() statement in on_action1_triggered(), I am not convinced it is called.

@JonB said in QFileDialog is works but invisible:

It actually has: look at the bottom, it is next to "FirstWindow" and is called "Archive".

@jsulm OIC!! Very odd.

@JonB Thanks for help, I solved it, I called other method in my constructor and it was blocking everything.
