Processo Ok or Cancel in a QFileDialog

[gt.beta2]

Hi

I'm using this function to get a file name.

void class::function(){
     QFileDialog::Options options;
     QString selectedFilter;
     QString fileName = QFileDialog::getOpenFileName(this,
                                 tr("QFileDialog::getOpenFileName()"),
                                 lineEdit->text(),
                                 tr("PNG image format (*.png)"),
                                 &selectedFilter,
                                 options);
     if (!fileName.isEmpty())
         lineEdit->setText(fileName);
}

void class::function(){
     QFileDialog::Options options;
     QString selectedFilter;
     QString fileName = QFileDialog::getOpenFileName(this,
                                 tr("QFileDialog::getOpenFileName()"),
                                 lineEdit->text(),
                                 tr("PNG image format (*.png)"),
                                 &selectedFilter,
                                 options);
     if (!fileName.isEmpty())
         lineEdit->setText(fileName);
}

To copy to clipboard, switch view to plain text mode 

How can i know if the user pressed Ok or Cancel?

Thanks

Basically user can only press OK when a filename is selected.

So filename not empty -> user pressed ok.

But imagine it wad a Dialog made by me ... how to teste if the ok was the button presed?

Use the QDialog::accept() and QDialog::reject() slots by connecting your buttons to these slots. Then you can find out what the user clicked by calling QDialog::result().

So the same thing is valid for the initial question about the QFileDialog?
Instead of testing if the field is empty i can test the accept or reject like said above?

Yes, but then you must use a file dialog instance. It won't work when using the file dialog's static methods.

OK ... now i managed to know if the dialog was terminated with OK or Cancel.

And let me make the last newbie question for today

Imagine a dialog with :

1. lineEdit
2. cancelButton
3. pushButton

I call this dialog from the main application and the i want to use the contents of lineEdit there. Let's sai ... make a copy to lineEdit_2.

How is this managed?

Thanks

Simply add a method to your dialog that returns the contents of the lineedit. Whenever you need the value, call that method. It's the same principle as with QFileDialog: when you need to know what files were selected, you call QFileDialog::selectedFiles()
