QFileDialog Error

[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.

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

I want links for this

[saitej]

@mrjj
QColorDialog works fine!!

[mrjj]

@saitej
Ok very strange..

Im not into QML but this seems to be sample

@mrjj

Thanks!!

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

@saitej
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

[mrjj]

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

[saitej]

@mrjj

:)
It's a custom class widget to display variables on real time

[mrjj]

@saitej
Just for test.
Could you try with a normal QpushButton for wid1 just to see if
it was something to do with the actual widget.
My brain cannot find any reason that a layout should do stuff to a dialog.?!

[saitej]

@mrjj

Ya. I think something is wrong in the custom class that is influencing the filedialog.

[mrjj]

@saitej
Hmm, im dying to know what that can be since
its hard to imagine other class affecting a dialog that way.
:)

[kshegunov]

@mrjj

its hard to imagine other class affecting a dialog that way.

All classes share the event loop, so that's why I mentioned it earlier.
