Status bar message tend to disappear

[maverick_pol]

Hi,

I have a custom MainWindow class coded by hand, not .ui file used.
I display a sample message:

statusBar()->showMessage(tr("----- This is status bar position -----"));

It's shown ok. When I move mouse over a menu the message disappears.

This is the only line when I use the statusBar.
[*]
When I add a widget to the status bar and set its test( Qlabel) then the message is the same []

Thanks
