Cursor not changing

I have a class that inherits from QMainWindow called CMainForm.

I have a menu action that triggers a method called menuPackageLogs().

At the begining of the method I set the cursor to Qt::WaitCursor, and at the end I set it back to Qt::ArrowCursor. In between I call a routine that blocks for a while. The problem is that my cursor never changes. It is always an arrow, never an hour glass.

I must be missing something fundemental here.
Here is an example of the method that gets called:

Code:

---

void CMainForm::menuPackageLogs()
{
    // Change cursor to wait cursor
    setCursor(QCursor(Qt::WaitCursor));
 
    bool bRet = UpgradeUtils::PackageLogs();
 
    // Change cursor back to standard arrow
    setCursor(QCursor(Qt::ArrowCursor));
 
    if (bRet == true)
    {
        QMessageBox::warning(this, tr("Package Logs"),
                            "Upgrade log files successfully packaged.");
    }
    else
    {
        QMessageBox::warning(this, tr("Package Logs"),
                            "Could not package Upgrade log files.");
    }
}

If anyone has any ideas, I am all ears. Thanks.

Are you sure this function is executed?
If it is, then maybe the PackageLogs exits very fast so you don't have time to see the difference.

Try adding QThread::msleep(5000); before or after the function call.See if you notice any difference.

I did a sleep() for 15 seconds... with no luck. My application just hangs till it is done sleeping. The cursor never changes.

Yes, use QApplication::setOverrideCursor to set the busy cursor and QApplication::resoreOverrideCursor to restore the arrow cursor.

Both these functions are static.

Just a lame idea which might work. Add this before calling bool bRet = UpgradeUtils::PackageLogs();

Code:

---

qApp->processEvents()
