How to use the "wait" animation?

[Sasler]

I'm working on an app that updates data from the internet. I want give the user some feedback that update is in progress.

How to use the default Maemo 5 "wait" animation? I have in mind that circle with lines.

You need to set atom _HILDON_WM_WINDOW_PROGRESS_INDICATOR of type XA_INTEGER with value 1 to your window to enable progress indicator. Then set 0 or remove atom to disable it.

Thanks, but how can I do it? Would someone be so kind to point me to some sample code?

You should use Xlib's XChangeProperty, there is an example in Maemo wiki.

In case you are using Qt 4.6 there is a wrapper for that:

QWidget::setAttribute(Qt::WA_Maemo5ShowProgressIndicator, true);
