Active window

[mrjj]

looks fine

So MainWindow::newfile is called ?

but newF is not shown or ?

@mrjj Everything works. Just tell me how to do it the way I asked? if you know

[mrjj]

@TETTRA
I really dont understand what u ask, else i would tell you.

void MainWindow::newfile() does nothing but showing the dialog so i dont understand your sentence

"the window is open, but the button that called it does not work. Until the window disappears."

But its not a button that calls it, its the QAction

So i do not know what is not working.

@mrjj In various programs there is a button that creates a new window in which you can for example draw and when creating this window a window appears that requests additional parameters (name, etc.) and that these windows would not have much, the button that called this window Is turned off. Like this.

@TETTRA said in Active window:

the button that called this window Is turned off

What you mean ? Like if u click it once, the window open. And the button is grey so u cant click on it again?
(before windows is closed ?)
is it to prevent to get multiple windows if u click many times on the button?

Yes

@TETTRA
You can use
button->setEnabled(false);
when you open dialog.

You must then catch when dialog closes and set button back to active.

@mrjj

I tried, but I did not succeed, you can write.

@TETTRA
What part did not work?

Here is sample using QDialog and a custom signal.

What part don't you understand ?
I put in comments in sample.

Ask about the places you are unsure about.
