QFileDialog::getOpenFileName linux doesn't work
-
Hello
I have a problem using QFileDialog::getOpenFileName and it does the same for QFileDialog in general.I have linux ubuntu 12.04 64 bits, Qt Creator 2.4.1 , Qt 4.8.0 (64 bit).
I have a simple code with one button:
void MainWindow::on_pushButton_3_clicked()
{QString cheminFichier = QFileDialog::getOpenFileName(this, "Ouvrir un fichier", QString(), "Text file (*.txt)",0,QFileDialog::DontResolveSymlinks|QFileDialog::DontUseNativeDialog|QFileDialog::DontUseSheet );}
There are no errors in compilation , no crashes , but when I press the button , nothing happens. I tried with other QFileDialog function and it doesn't work also.
(When I try to use QFileDialog on windows 7 64 bit , QT crashes during compilation)
Could you help me to solve this , to open FileDialog window on linux ? Maybe there are other solutions.
thanks :) -
Hi and welcome to devnet,
The question might be silly but: are you sure that this slot is called ?
You should also consider updating your Qt version, the latest (and last) version of Qt 4 is 4.8.7.
What version of Qt are you using on Windows ? What do you mean by crash during compilation ?

Problem solved , thanks to your silly question :p
In deed the slot wasn't called because before I probably put an other button that I deleted with the same name .
So I changed name here and deleted the previous switch case of the previous button in "moc_mainwindow.cpp".On windows I have Qt5.5 and I meant that Qt is frozen. Probably with the right file now it won't do anymore.
Thanks :)

@bejard You should never edit moc_*.cpp files, they are generated during compilation!
What do you mean by "Qt is frozen"? Do you mean QtCreator is frozen? Qt is a framework, it cannot be frozen during compilation.@jsulm yes but as I deleted in wrong way the previous button I had still it in this file and it did some errors ^^ now it works I saved it.
I meant QtCreator yes : loading loading loading at middle of compilation ...then "not responding"
Forced to kill the task -
Instead of editing the moc file you can just rebuild you project completely (you can delete the build folder before you rebuild).
