Restore widget default palette color
-
I start life with widgets whose palette has not been altered, so they are at whatever the "default" is for the windowing system. I dynamically change (text color) like:
QPalette palette = lineEdit->palette(); palette.setColor(QPalette::Text, colour); lineEdit->setPalette(palette);At a later date I want to remove/restore it to the original default.
What is the canonical way to do this? E.g.
- I don't wish to have to save what the color was before I changed it.
- I'm not seeing a "restore default color/palette", like say
palette.setDefaultColor(QPalette::Text), that's what I thought there would be, is there something? - Do I have to do something like create a temporary
QLineEditto access its palette for the color to copy?
EDIT Ah, I just saw the default
QPalette::QPalette()says:Constructs a palette object that uses the application's default palette.
That looks good! I thought it would be an "empty" one.
Even better,
QPalette QApplication::palette(const QWidget *widget), https://doc.qt.io/qt-5/qapplication.html#paletteIf a widget is passed, the default palette for the widget's class is returned. This may or may not be the application palette.
So I think have answered my question, that's what I should use with my widget type to get back the original default color value to reset, right?
