Solved QToolBar not using QIcon::Mode

[Perdrix]

When I populated my ToolBar I used QIcons with four images, one for each QIcon::Mode.

So the code looks like this:

    QIcon selRect;
    selRect.addFile("C:/Users/amonra/Documents/GitHub/DSS/DeepSkyStacker/Buttons/ButtonSelect_Up.bmp", iconSize, QIcon::Normal);
    selRect.addFile("C:/Users/amonra/Documents/GitHub/DSS/DeepSkyStacker/Buttons/ButtonSelect_Disabled.bmp", iconSize, QIcon::Disabled);
    selRect.addFile("C:/Users/amonra/Documents/GitHub/DSS/DeepSkyStacker/Buttons/ButtonSelect_Active.bmp", iconSize, QIcon::Active);
    selRect.addFile("C:/Users/amonra/Documents/GitHub/DSS/DeepSkyStacker/Buttons/ButtonSelect_Down.bmp", iconSize, QIcon::Selected);

    :
    : Similar for the other Icons
    :
    t.setOrientation(Qt::Vertical);
    QAction * rectAction = t.addAction(selRect, "", &editor, &DEditStars::rectButtonChecked);
    QAction * starsAction = t.addAction(selStars, "", &editor, &DEditStars::starsButtonChecked);
    QAction * cometAction = t.addAction(selComet, "", &editor, &DEditStars::cometButtonChecked);
    QAction * saveAction = t.addAction(saveButton, "", &editor, &DEditStars::saveButtonPressed);

    QActionGroup selectionGroup(&t);
    rectAction->setCheckable(true);
    starsAction->setCheckable(true);
    cometAction->setCheckable(true);
    selectionGroup.addAction(rectAction);
    selectionGroup.addAction(starsAction);
    selectionGroup.addAction(cometAction);
    selectionGroup.setExclusive(true);

But QToolBar appears to use only the QIcon::Normal version for all the buttons, and uses a small offset to indicate an item in the action group has been "checked", rather then using the QIcon::Selected image (I don't mind it keeping the small offset).

Also it doesn't ever use the QIcon::Active image when the mouse is over the button :(

Is it possible to persuade the Toolbar to do this, or do I need to build the tool bar the "hard way" by adding sub-classed QToolButton widgets?

"checked" is QIcon::On from QIcon::State.

"checked" is QIcon::On from QIcon::State.

@Bonnie Oh! OK, that's a surprise! I'd very much have expected the checked state to use QIcon::Selected.

I changed the code to do this:

    QIcon selRect;
    selRect.addFile("C:/Users/amonra/Documents/GitHub/DSS/DeepSkyStacker/Buttons/ButtonSelect_Up.png", iconSize, QIcon::Normal);
    selRect.addFile("C:/Users/amonra/Documents/GitHub/DSS/DeepSkyStacker/Buttons/ButtonSelect_Active.bmp", iconSize, QIcon::Active);
    selRect.addFile("C:/Users/amonra/Documents/GitHub/DSS/DeepSkyStacker/Buttons/ButtonSelect_Down.bmp", iconSize, QIcon::Normal, QIcon::On);

and that does switch the icon for the checked state - thank you for that.

I'm guessing from what you didn't say that I can't get it to switch to the active Icon when the mouse is over the button without going down the sub-class route?

@Perdrix
No, that's because I don't know about that. :)
I've set checked pixmaps, but had never set a "hovered" one.
But I just tested QIcon::Active. Seems to work fine when mouse over.

[Perdrix]

Yes indeed. Once I'd corrected an error in the name of the Active bitmap it works for me too!!

Thanks a lot!
