I see that the checkbox svg image drawn using the delegate paint method (subclassed from QStyledItemDelegate) in a QTreeView column looks different than drawn using the css file. I mean the borders drawn are thin.
In the attached picture, column B checkbox is drawn using the svg file declared in the css file which is as expected. Column A is drawn using the paint method and I expect it to look same as the column A.
When the monitor display scale settings is 125%, the drawn image in column A using the the below paint code looks the same as the column B and is ok. But when the settings is 100%, the column A image looks thin and does not look same as column B which is not good.
How do I resolve this issue ? I am not sure if I am missing anything here. Thanks in advance.Below is the snippet of my paint method implementation.
void ModelDelegate::paint( QPainter* painter, const QStyleOptionViewItem& option, const QModelIndex& index) const { .... else if (index.column() == Model::DisabledColumn) { painter->save(); QStyleOptionViewItem option_copy(option); option_copy.icon = QIcon(":/icon/checkbox_empty.svg");; QRect rect = option_copy.rect; rect.adjust(3, 0, 0, 0); option.widget->style()->drawItemPixmap( painter, rect, Qt::AlignLeft | Qt::AlignVCenter, icon.pixmap(16, 16)); painter->restore(); return; } }
