[Qt-interest] layout and QTreeWidget

[Tony Rietwyk]

1) I used QtDesigner to learn how to set layouts - they are very powerful,
but the documentation is so sparse, and does not cover the interaction of
all the variables involved. 
 
2) The documentation of the model views is also really bad. I used
itemChanged to trap changes to checkState. But it is not obvious when this
signal is fired - is it fired when the flags change? when the expanded state
changes? whenever setData is called? etc. 
 
It seems Trolltech spent so much time getting new features in, then let
themselves down by poor doco. It's a shame! 
 
Hope that helps.

Hi,
I have two problems.
1. I use QVBoxLayour to align two widgets. I want the bottom one to
maintain square shape as I resize.  How to do it?

    What are the widgets ??Is it a tree view and checkbox


2. I use QTreeWidge with check box. I want to send a single when I
change the state of the checkbox. However I try all the signals
mentioned in QTreeWidget class reference and only signal
itemSelectionChanged() can connect to my slot, but it is not what I want
signal.

   If you cannot then create your own signal by creating a class which
inherits the QTableWidget. or the other way.Not clear what exactly you want.



Thank.

Yixun
