Clipping of (OR maybe background colour of) QToolbar Icons

[mrjj]

@Perdrix
Ah, its when you hover / click it ?

Its due to the auto raise feature, i believe.

@mrjj The top three icons are checkable. So if I click the second icon and hover over the third one I see:

@Perdrix said in Clipping of (OR maybe background colour of) QToolbar Icons:

{background - color:transparent;}

This may be quite orthogonal to your issue, but are you sure this is acceptable written like that?

[Perdrix]

@JonB I wasn't sure so I changed it. And this is what I now see:

So changing it to:

QString styleSheet(QString(
"QToolButton {background-color:transparent;} "

did change things and not for the better :(

So "background - color" was wrong!

@Perdrix can not you add round radius to that button only on the top part?

Stylesheet: border-top-left-radius: *px; border-top-right-radius: *px;

@Perdrix
I know nothing :) But (provided I understand right) I would expect:

QToolButton{border: none; background-color: transparent;}

(I assume you have the correct transparency on your icons. Perhaps you should confirm this?)

Just OOI isn't that what https://stackoverflow.com/questions/69755056/how-to-set-qaction-to-have-transparent-background-inside-qtoolbar says and is similar enough to yours??

If anything else fails, then you can try setMask
If does make the area round/as the icon but can a bit annoying to align.
More over, the checked default drawing might not be visible.

#include "QBitmap" // must have to use setmask
....
   setStyleSheet(styleSheet);

    auto list = ui->toolBar->findChildren<QToolButton *>();
    for (auto *w : list) {
        w->setAutoRaise(false);
        QIcon ico = w->icon();
        QPixmap pix = ico.pixmap(ui->toolBar->iconSize());
        w->setMask(pix.mask());
    }

@JonB Pretty sure the background of my icons are correct:

Here's one of them to play with:

[Perdrix]

@JonB You sir, are a star! border:none; made the difference!!!

So:

QToolButton {border: none; background-color: transparent;}

worked a treat!

Why did adding border:none; fix it please?

QSS magic/guess/example/makes sense to remove anything not needed.
