/* QDesignerDialog / QDesignerWidget are used to paint a grid on QDialog and QWidget main containers | |
* and container extension pages. | |
* The paint routines work as follows: | |
* We need to clean the background here (to make the parent grid disappear in case we are a container page | |
* and to make palette background settings take effect), | |
* which would normally break style sheets with background settings. | |
* So, we manually make the style paint after cleaning. On top comes the grid | |
* In addition, this code works around | |
* the QStyleSheetStyle setting Qt::WA_StyledBackground to false for subclasses of QWidget. | |
