setWindowTitle() update title immediately

[vladest]

Hi

I'm trying to update window title immediately with construction like this:
setWindowTitle(tr("bla-bla");
qApp->processEvents();
<some job>
setWindowTitle(tr("bla-bla1");
but this working only once due program runtime. I.e. I can see bla-bla only once. bla-bla1 shows every time

what I'm doing wrong?

Thanks

Hi, vladest

Actually where you are putting this line setWindowTitle() is very important accrording to that it will affect you runtime.
Try this :

qApp->processEvents();
<some job>
setWindowTitle(tr("bla-bla");
<some job>
setWindowTitle(tr("bla-bla1");

Hi rahulvala

Unfortunately, this didnt help

Couldnot interpret your problem. With the above code bla-bla will be shown and the updated with bla-bla1 on subsequent call to setWindowTitle(). Isn't that you want?

Hi
I want to see both bla-bla and bla-bla1, but see only bla-bla1

First you can not see both at the same time .
And second when the title change it's so fast that you can not see it and finally you will see only bla-bla1.

Well, between this two title changes a gap in 2-3 secs. So, too quick it is not my case

It's really bad idea to make a blocking calls for 2-3 seconds. Use threads instead.

Test application

#include <QtGui>

int main (int argc, char **argv)
{
    QApplication app(argc, argv);

    QMainWindow win;
    win.show();

    win.setWindowTitle("1");
    app.processEvents();
    sleep(5);
    win.setWindowTitle("2");

    return app.exec();
}
