QPushButton when disabled becomes grayed out

[alenn.masic]

Hello

When I disable QPushButton it becomes grayed out by default, how can I leave it as it is even if it is disabled. I have icon on QPushButton and when I disable button I want icon to stay as it was before. How can I solve this?

Either reimplement the button's paintEvent() and change the options that get passed to QStyle::drawComplexControl() (or whatever gets called there) or don't make the button disabled but just disable triggering it by intercepting its mouse and key events.

Either subclass and reimplement appropriate event handlers or install an event filter on an existing object.

Shouldn't it be possible just to change the palette? I mean, replace all colors of QPalette::Disabled with those of QPalette::Active. (Not tried.)

No, the icon will still be greyed out. But I think it might be possible to explicitly set the regular icon pixmap as the disabled icon pixmap using QIcon::addPixmap() and passing Disabled as the mode.

I solved it using stylesheet. When I disable button I repeat this command: button->setStyleSheet("background-image: url(path_to_image);");

Aside from the mechanics of how you get this to work, why would you want to show a button as enabled when it isn't? There's a reason why there are various states for UI controls (enabled, disabled, selected, etc.) - it is to give users a visual clue about what they can (or can't) do at a given point, or what will happen by default (the selected button will be "clicked" if you press Enter on a dialog).

Why would you want to implement a GUI that is deliberately confusing to users? I can see someone repeatedly clicking on this button, and getting angrier each time because nothing happens.

Because I'm using my own icon to show that button is disabled. I only need to put big X on top of my button and that will indicate it is disabled (I'm making a game)

OK, that makes sense. As long as you show the user somehow that "You can't press this button now", then that is consistent with what the user expects.
