QFileDialog

Punt

Hi,

i'm doing

    QString homePath = QDir::currentPath();
    QString filename = QFileDialog::getSaveFileName(this, "Enregistrer sous...", homePath, "Configuration (*.xml)");

    saveConf(filename);  //which create a XML etc... (this function is working)

But here, if I manually close the QFileDialog, what happen ?

I would like to do something like :

if( myQFileDialogIsClosedOrFailedOrWhateverYouWant ){
    QMessageBox::warning(......);
else
    saveConf(filename);
}

is it possible to do that ?

By the way, is there a problem with QFileDialog on W10 ?

When I use it there's warning like

shell\comdlg32\fileopensave.cpp(9456)\comdlg32.dll!74260750: (caller: 74253458) ReturnHr[PreRelease](1) tid(2b88) 80070490 Élément introuvable.
    CallContext:[\PickerModalLoop\InitDialog\FileDialogInitEnterpriseData]

Test this:

if(filename.isEmpty())
QMessageBox::warning(....)

What about warnings ?

@HenrikSt.

Sorry I was busy..

these warnings :

shell\comdlg32\fileopensave.cpp(9456)\comdlg32.dll!74260750: (caller: 74253458) ReturnHr[PreRelease](3) tid(5f4) 80070490 Élément introuvable.
    CallContext:[\PickerModalLoop\InitDialog\FileDialogInitEnterpriseData] 
shell\comdlg32\fileopensave.cpp(9456)\comdlg32.dll!74260750: (caller: 74253458) ReturnHr[PreRelease](4) tid(5f4) 80070490 Élément introuvable.
    CallContext:[\PickerModalLoop\InitDialog\FileDialogInitEnterpriseData]

When I use getSaveFileName(...);

My French is pretty rudimentary, but "Élément introuvable" is a bit confusing. I don't understand what element can't be found, and somehow this comes from comdlg32 ...
I think you're safe to ignore these warnings for now, but if you find any strange effects do tell.

Maybe you cab post your completely code here for understanding the error ?

@HenrikSt.

void myClass::on_pushSaveCom_clicked(){ //On click QPushButton (save my configuration)
      
      //set some variable according to my UI
            
      QString homePath = QDir::currentPath();
      QString path = QFileDialog::getSaveFileName(this, "Enregistrer sous...", homePath, "Configuration (*.xml)");
      if(path.isEmpty())
            return;

      saveConf(path); //which create the new XML according to my new value set earlier in this function
}

@Punt
Your code looks fine to me. So as I said, I think it's safe to ignore those warnings for now. If you observe some side effect, report it here again so we could attempt to track it down.
