Hi,

It depends on how you use it.

Show your code.

I use this functioin, when all windows hiden:

SGaist

So you hide all your application windows and only show the dialog ? Correct ?
And there's no entry on the desktop bar related to your dialog ?

Mikeeeeee

@SGaist said in QDialog in Windows haven't icon in taskbar:

Correct

Yes, it is correct

SGaist

Please provide a minimal runnable script that shows your issue.

Mikeeeeee

I create QAplication, create object class with Qwidget (this class QDialog), show QDialog (QWidget is hiden)

SGaist

As I already requested: please provide a minimal runnable script that shows that behaviour.

Mikeeeeee

    # print(sys.argv)

    if len(sys.argv) >= 2:

    default_qgis_path = '/usr'

    if conda_prefix is not None:
        default_qgis_path = conda_prefix

    boolEnter = mainWindow.dialogRegistrationFunction()
    if boolEnter == None:
        boolEnter = True

    if boolEnter:
        app.exec()

SGaist

You know that this is neither a minimal nor runnable script that shows your issue ?

There's no definition of MainWindow.
It requires an installation of QGIS
You are using a conda environment somewhere but it's not clear whether your script runs within it or just makes use of it at some point.

@Mikeeeeee You think this is "minimal" script to reproduce the issue?

Mikeeeeee

@jsulm said in QDialog in Windows haven't icon in taskbar:

You think this is "minimal" script to reproduce the issue?

Yes

Mikeeeeee

Need do this

self.dialogRegistration = QDialog()

@Mikeeeeee
You are asking other people to spend their time looking through your code and figuring what might be wrong. "Minimal" essentially means "the minimum number of lines to reproduce the problem; all extraneous lines have been removed". Yes, that means to get an answer you are expected to spend some time going through what you are working on and reduce it to the minimum necessary to reproduce your problem. Yes, that takes a bit of effort. Just like you are asking other people to spend in order to help you....

Purely as an example, in your code why do I have to wade through lines & lines of lineEditName and lineEditPassword code, with fixed widths, stylesheets and everything else, to reproduce your question about a dialog not having an icon in the taskbar? Did you try removing them before you posted to see whether they affect the issue?

Good luck finding someone who will care to take the time to answer, given how much time you have taken to produce the example.
