[Interest] QTreeWidget displays blank widget

[Nicolas Krieger]

I have finally managed to do what I wanted in using styleSheets. Not 
really beautiful.



If a have a widget containing all other widgets, for which I defined a 
styleSheet, the color will be displayed only for the children (see last 
example).
The "solution" is to have a child widget that contains all other widgets.
In this example, a stylesheet is define for "widget_2". It is correctly 
displayed in the tree.





In this example, no stylesheet for "widget_2" and the palette's 
background color of "SimpleWidget" is blue.




In this example, there is no "widget_2" and a stylesheet is defined for 
"SimpleWidget".
Using the first example can be a solution.
