Getting filename by QFileDialog

[yogeshm02]

Are not you better off using QFileDialog::getOpenFileName()?

filename = QFileDialog::getOpenFileName(this);

filename = QFileDialog::getOpenFileName(this);

To copy to clipboard, switch view to plain text mode 

EDIT: Sorry, did not read your entire post. You can go about this like:
Mainwindow.cpp
Void Mainwindow::XXXX
{
QFileDialog filedia;
filedia.

filedia.resize(200,320);
filedia.exec();

filename=filedia.XXXXXXXXXXXXXXXXXXXXXXXXXXXX

filedia.close();
if(filename.count() == 0 || filename.at(0).isEmpty())//Not sure if second condition is necessary, you can check it yourself, i'm currently away from my PC
{
QMessageBox msg;
msg.setText("no input file specified");
msg.exec();
return;
}
le->setText(filename.at(0));

}
