/* 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.
