EditField, ArrayCtrl, LineEdit, DocEdit, ColumnList, TreeCtrl now have "NoBackground" option.
If active, background is no painted, so anything begind widget is visible.
Method activates Transparent too. Anyway, alternative use is to override Paint method (drawing the background and then original Paint method) - in this case it is more optimal to setup the mode back to Opaque.
What is the difference between NoBackground and Transparent then?
Bas
Good question. I was sitting at the issue for 20 minutes before deciding that two are distinct.
The reason is described above: You might want to provide thr background by overriding Paint method. In that case, Transparent is not necessary. And it is slower than "direct" painting. So by keeping features distinct, you can achieve better performance in special cases.
