> Hi all,

> Here is the test ui file:
> https://gist.github.com/4119155#file_test.ui
> It's a simple main window with a QHBoxLayout inside a QWidget. Margins 
> are all set to the same value: 5. Now, the generated code contains 2 
> calls to setMargin, one for 5 (correct) and another one with 0 
> (incorrect) for the layout:
> https://gist.github.com/4119155#file_test.py
> See lines 28-29.
> By inspecting uiparser.py, in function createLayout, an extra 'margin' 
> element is added (~line 433) because the layout is child of a QWidget 
> which is not the child of the main window. The code in that function 
> checks if there are individual margin elements but looks like fails in 
> the case where there is a single 'margin' element, that is, when all 
> margins are equal. If at least one margin is different then problem 
> doesn't appear.
> Is this a bug in the ui parser or am I doing something wrong here?

Should be fixed in tonight's snapshot.
