[Qt-interest] Updating the QPlainTextEdit's background color

[NoRulez]

I've forgotten to say that I use these in a function within a subclass of QPlainTextEdit.

This function/slot is triggered if the font settings have changed.

If I open a new QPlainTextEdit, the new palette settings are present, but I want to change the palette settings for already opened QPlainTextEdit's too.

Best Regards
NoRulez
