Need help identifying a graphical change on a QLabel

[viamodulo]

When I disable a button the text of the QLabel becomes slightly blurred. Here's a picture : Does anyone know what the name of this effect is ? I noticed it disappears if I put the TextFormat of the QLabel to QRichtext. Here's what it looks like when removed:

I've also discovered that the extra outline color is QPalette::light() (white by default).

Hey thanks ! That was a good idea, I found what it is. It's the QStyleHint::SH_EtchDisabledText that adds that behaviour.

Hi and welcome to devnet,

What is the relation between disabling a button and that QLabel ?

[viamodulo]

The QLabel is the label of that button. It happens on other QLabels in the app that are not necessarily on buttons. It happens when they are disabled. (I disable the whole main window when showing a modal).

You can take a look at the implementation of QLabel's paintEvent to get started.
