Re: Qt 6.0 development and qelectrotech
For the KColorButton, we use it only because the button he is colored according to the current color. If you want to remove the dependency, we can copy the code of kcolorbutton to qet (I think it's very little) but we need make it available in Qt Designer.
For KAutoSaveFile class, we need to keep it because we use the stalesFiles funtion when Qet crash to restore a backup file.
Also we alreday use QSaveFile in Qelectrotech, see QET::writeXmlFile.
