Get state of a QIcon?

Calicoder

Howdy fellow QT'ers folks, hope everyone is doing well. Been playing with creating QIcons for the past week, checked the official docs and don't see how one can fetch the state the icon is currently in?

app.h

private:
    QIcon goSign;

app.cpp

goSign.addPixmap(QPixmap(":/img/go.png"), QIcon::Normal, QIcon::On);
goSign.addPixmap(QPixmap(":/img/stop.png"), QIcon::Normal, QIcon::Off);

I can set the QIcon by using the proper QIcon::State value but can this be fetched afterwards? I figured I could grab the int value of the enum QIcon::State but the QIcon goSign doesn't have a getState function.

Any ideas on how to handle this would be greatly appreciated. Thanks

I agree that from what I can see in the docs there are no getters for the QIcon::Mode or QIcon::State: they seem to be passed into constructor/methods only. So if you need that information suggest subclass from QIcon and save mode/state into a member variable. Or in your case I think you just need to create a wrapper class for the QPixmap you create saving the icon state/mode with it.

@JonB Appreciate the 2nd set of eyes to look that over. That's what I'll do before setting the icon. Thanks so much!

Further, it's not really a QIcon which has the state or mode. It is that it can generate icons for them from the pixmaps it has available.

A QIcon can generate smaller, larger, active, and disabled pixmaps from the set of pixmaps it is given. Such pixmaps are used by Qt widgets to show an icon representing a particular action.

You went

goSign.addPixmap(QPixmap(":/img/go.png"), QIcon::Normal, QIcon::On);

So it's the QPixmap you are adding which has the Normal/On attributes.
