qpushbutton not disabling properly

[jpn]

The shortest possible way to solve the problem is to add a call to QCoreApplication::processEvents().

void RoboSearch::listFiles()
{
    searchButton->setEnabled(false);
    // let the application process its events
    QApplication::processEvents(QEventLoop::ExcludeUserInputEvents);
    //code is searching through files, so it takes ~5s
    searchButton->setEnabled(true);
}

void RoboSearch::listFiles()
{
    searchButton->setEnabled(false);
    // let the application process its events
    QApplication::processEvents(QEventLoop::ExcludeUserInputEvents);
    //code is searching through files, so it takes ~5s
    searchButton->setEnabled(true);
}

To copy to clipboard, switch view to plain text mode 

5s is a long time for a GUI application to be frozen so you might want to call the same method every now and then during the search.

Thank you very much!

I am now trying apply it to another part of my code, where a pushbutton connection opens a dialog, but the dialog won't actually open until I close the original window.... hopefully I'm on the right track.

Hmm sorry, but it's hard to say anything without seeing relevant code.
