busy progress bar without thread ?

[bmn]

Works for me:

// main.cpp
#include <QtGui>
 
int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QProgressBar progressBar;
    progressBar.setMinimum(0);
    progressBar.setMaximum(0);
    progressBar.show();
    return app.exec();
}

// main.cpp
#include <QtGui>

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QProgressBar progressBar;
    progressBar.setMinimum(0);
    progressBar.setMaximum(0);
    progressBar.show();
    return app.exec();
}

To copy to clipboard, switch view to plain text mode 

Don't work... see

QApplication app(argc, argv);
QMainWindow window;
QProgressBar* progressBar = new QProgressBar(&window);
progressBar->setMaximumHeight(16);
progressBar->setMaximumWidth(200);
progressBar->setTextVisible(false);
progressBar->setMaximum(0);
progressBar->setMinimum(0);
 
progressBar->show(); // ??? don't move the bar
 
window.statusBar()->addPermanentWidget(progressBar);
window.statusBar()->showMessage("Loading");
window.show();
app.exec();

QApplication app(argc, argv);
QMainWindow window;
QProgressBar* progressBar = new QProgressBar(&window);
progressBar->setMaximumHeight(16);
progressBar->setMaximumWidth(200);
progressBar->setTextVisible(false);
progressBar->setMaximum(0);
progressBar->setMinimum(0);

progressBar->show(); // ??? don't move the bar

window.statusBar()->addPermanentWidget(progressBar);
window.statusBar()->showMessage("Loading");
window.show();
app.exec();
