Hello,Everyone:
I am a newbie guy in QT development, and now i face a problem which frustrated me a few days.
I use QT s60 version for E6/E7. The application is actually a totally full screen app, and i use the QTabWidget and QListView class for my most of widgets.
I descripted the widget flow like this:
mainWindows->QTabWidget->QWidget1(contain a QListView)
->QWidget2(contain a QListView)
->QWidget3(contain a QListView)
Each time when click a item in QListView, it will show a full screen QWidget above, it can also return to the root Tab Widget by a QPushButton.
Now the problem is:
This app must support keyboard event and touch event, the touch event work perfert, but the keyboard focus event works very weird, i only use the up/down/left/right/select key to navigate between each widget and item.
1. I set focusPolicy value StrongFocus for all the needed widget included the QListView.
2. When I set all the new full screen widget as the child of the last one, This new widget will be hard to be focued and weird, i mean the parent widget is always in the focus chain, but i want the new full screen own its focus chain,that means modal.
By the way i also use setTabOrder and set focus to the new one, it does not work.
3. When I set all the full screen widget as the model, which means it is a new windows, the focus chain can cycle well in this new windows, but it display weird, it will own a flash black screen time when switch between 2 widgets.
I perfer to use the child/parent method to switch between every widget, but i want to the child widget own his cycle widget in itself, How can i achieve that target.
Thanks anyway.
(The navigation widget in iphone is a good example)
