<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Thomas, what exactly did you mean with "QDialogButtonBox::addButton should do correctly"? Looking at Qt's code again, I can confirm that QDB::addButton(StandardButton) is the only one invoking the private createButton method which in turn sets an icon if ButtonsHaveIcons is true. The other QDB::addButton methods simply call the private addButton method which will do a layout step by default, but I don't see where an icon would be added.
Should I understand that `style->standardIcon()` is invoked during drawing as a function of button's role?
I cannot find evidence of that in QtCurve. But if that is the case nonetheless, why are we patching KDialogButtonBox again? And how do you explain that removing the icon after a button is created has the effect it has (when the style will continue to see the button role)?</pre>

This was mostly noticeable in applications built on kdelibs4support.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">It seems that the actual culprit is in Qt's QPushButton implementation (https://bugreports.qt.io/browse/QTBUG-49887), but it is possible to work around it in <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">KPushButton::paintEvent</code>, by removing the icon (forcing it to the null icon) in the option instance, before handing off control to the painter.</p></pre>
