[Qt-interest] Focus on a hidden widget.

[Malyushytsky, Alex]

According to my impression you can’t simply call setFocus() right after show().
What you can do is to make sure setFocus is called after widget is displayed ( as a result  of show ).

Few ways come in mind:

 -Put setFocus in custom slot ( for example myslot() )
Replace setFocus( … ) call with
QTimer::singleShot(0, this, SLOT(myslot()));

myslot() will be called when event loop take care about all events .

-Another possible way to handle it (never tried but logically should work )
 - is to enforce application event loop  to process events before setFocus:

show() ;
QCoreApplication::processEvents();
setFocus(…)

Hi

I am facing a very peculiar problem. My widget is not getting focus.
When i create the widget i call following two functions on it
show()
setFocus()

this kind of code used to work. But all of a sudden i am in a situation where it doesnt seem to work. As I understand " if set focus is called on a widget that is not shown yet, it will get focus as soon as it becomes visible". Am i wrong here?
