Hey, I want to change the default highlight color when item in ListView is selected. The default color is blue. I want to change it to red. I googled, and i found QPalette. QPalette::Highlight - A color to indicate a selected item or the current item. By default, the highlight color is Qt::darkBlue. By default, the highlighted text color is Qt::white. But i have no idea how to implement it. I found a few examples but I have no idea how to do it. QPalette p palette ; p.
Hey thank you for your reply. Now i know how to implement it. When i change the Window to Highlight, it don't work either.
Is this blue color perhaps coming from listDelegate1? I don't think ListView should have any highlight component by default. Does the implementation of Products1Item set a color when pressed, or similar? One way to test where it is coming from would be to replace listDelegate1 with a simple Text item, and see if you still get any default highlight color showing.
Hey mbrasser, really?Contour earring
I didn't know that. However, I tested like you said, replaced listDelegate1 with simple Text, yeah there is blue color showing. In my Products1Item, I did not set any color when pressed, only the settings for the text to show out.
In all my ListView, when selected, there are blue color highlight, even though I did not set any highlight. What about Back button? The back button also have default blue color when selected. The blue highlight is most likely coming from the ListItem.
You are right mbrasser.Who is larz
It came from the ListItem. Thank you for correcting me. I will google from here and see what I can get. Thank you for your reply.
