QFileDialog Error

[saitej]

@mrjj

I tried the same code in the same system. It works on a new project but not on an existing one. I am unable to find a valid reason for this unusual behaviour

[mrjj]

@saitej
ok. its really , really odd.

Could you try with the
QFileDialog::DontUseNativeDialog
flag and see if its the ubuntu dialog that is strange?

[saitej]

@mrjj
It didn't work :(

[saitej]

@mrjj

I will try to implement the same in qml. How to open file dialog in qml through a slot/function?

[mrjj]

@saitej

Same thing happens even with flag?

Hmm. I really have no idea what can do this.

Also since it works normally in default app and
the static call is the same.

Have you tried some of the other dialogs ? like COlorDIalog?

[saitej]

@mrjj
Nope. Any links would help

[mrjj]

@saitej

Its like the getOpenFileName, just to get a color and not a filename.

http://doc.qt.io/qt-5/qcolordialog.html

I just wonder if that is funky too.

@saitej

@mrjj

Thanks!!

I tried through QML also but am getting the same result.

That's really strange. Can your share a minimal runnable code example so that other users can try to reproduce the behaviour on their platforms?

[saitej]

I think this guy might have faced a similar problem. The code that works for him doesnot work for me :( .

[mrjj]

@saitej
But you call the function on a menu click?
not in mainwin constructor ?

since it just in that project, im out of ideas. your Qt should be fine.

[saitej]

@mrjj
Ya!!

Hi,'

Yes, the dialog shows up in full screen and also I am unable to resize it from the bottom

It sounds like the event loop is blocked. I don't see how that might be happening from your snippet, but perhaps you could post the rest of the code - the whole method and how it's called?

Kind regards.

did you try to use the debug mode for track errors and see variables instances ?
Is your two differents projects has same files contents (or the second project is just a test case maybe ?). If this two projects are new, then use a tool for compare files contents to show differences appears.
then... you could also try to use valgrind tool from qtcreator.

Mainwindow.cpp

QAction *loadfile = new QAction("Load File",this);
ui->menuWidgets->addAction(loadfile);

connect(loadfile, SIGNAL(triggered(bool)),this,SLOT(onLoadfile()));

void MainWindow::onLoadfile(){
    QString fileName = QFileDialog::getOpenFileName(this,
                                                        tr("Open File"),QDir::homePath() , tr("Kml Files (*.kml)"));
        qDebug() << "Loading File"<< fileName;
        QFile file( fileName );
        if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
            return;
}

Hi guys

I have boiled down the error to a line which when commented the filedialog works but I don't see any reason how that line is effecting the filedialog. I will need that line in my project so if someone can tell me how it is affecting the filedialog, It will be very helpful.

Thanks

 ui->sideLayout->addWidget(wid1,Qt::AlignBottom);

This line adds a widget to the sidelayout which is a vertical layout added in the mainwindow.ui file through the designer.

Note: There are other layouts along with the side layout but they are not influencing

hi
That is like epic strange.
What type is wid1 ?
