Update Windows Title in Embedded Application

[SGaist]

Hi,

Qtopia ? Are you locked to it ? That's a project that has reached EOL 8 years ago so it's not necessarily a good idea to start a new project with it.

Hi @SGaist,
Its a new device for me, and I am following the base code provided by the device vendor. I don't know how to change the architecture and if i do something how to make it work on device.
I tried hello world ui application, compiled successfully but it gives me run time exceptions on device.

Hope this answers your query.

Thanks

You should check with the vendor if you can use something a bit more recent.

As for your error, can you get a stack trace ?

Hi @SGaist,

Sorry for delayed response as I am woking in Qatar and we have weekend for Friday/Saturday.
I tried again the same thing and I am not getting exception now, no idea what I had done before, may be some uninitialized pointer that I may have fixed when moving forward to application logical code.
Currently as I mentioned that I am not getting exception but issue is that the main window title is getting updated when the control is returned back to main constructor. Also to mention that I have disabled the push buttons in the same function and that code is working fine:
For the main window title I have placed following line of code:

    setWindowTitle("PURCHASE");
    centralWidget->update();
    centralWidget->repaint();

Thanks

The QMainWindow title has nothing to do with the central widget.

Hi @SGaist,
Can you please write me a line or reference on how do to update QMainWindow title in my code as I am not using "ui" component so its something unknown for me.

Thanks

[SGaist]

Well:
@Kashif said in Update Windows Title in Embedded Application:

setWindowTitle

of your QMainWindow is the right method AFAIR.

Can you show what you get ?

Hi @SGaist,

I used this function in my code but the title is getting updated only when the control returns back to push button calling event (the class constructor where I have defined central widget and buttons, code is pasted in third comment)

Thanks

[SGaist]

Why are you calling QWidget::setWindowTitle rather than just setWindowTitle ?

Hi @SGaist,

I tried both and the outcome is same.

Thanks
