I’m still struggling with how to customize the selection color for items on a
QTableView
I use a QStyledItemDelegate.
In the paint(painter,option,index) method I create my own QPalette based
on
selection etc and then call the base class paint function.
QStyleOptionViewItemV4 subop = option;
QPalette pal = qApp->palette();
if( selected ) {
pal.setColor(QPalette::Highlight,Qt::darkGray);
pal.setColor(QPalette::WindowText,Qt::white);
pal.setColor(QPalette::HighlightedText,Qt::white);
pal.setColor(QPalette::Text,Qt::white);
subop.state |= QStyle::State_Selected;
subop.palette = pal;
}
BaseClass::paint(painter,subop,index); // Note: subop.
(previously posted as
http://lists.qt-project.org/pipermail/interest/2016-January/020760.html). I
currently color the rows with custom colors based on the data being shown
in
each row in my model’s data(const QModelIndex &currIndex, int role)
when role ==
Qt::BackgroundRole.
For future readers, which will probably be me again 6 months from now, all I
needed was
to do exactly what I told you to do on the 5th:
to create a QStyledItemDelegate with paint() reimplemented as follows:
"A QStyledItemDelegate doing a similar trick would work as well."
void customStyledItemDelegate::paint(QPainter *painter, const QStyleOptionViewItem
&option, const QModelIndex &index) const
{
QStyleOptionViewItem subop(option);
" Just make a copy of the style option,"
subop.state &= ~(QStyle::State_Selected);
" reset the selection flag in the state variable"
QStyledItemDelegate::paint(painter, subop, index);
"and pass that on to the base class."
}
Then when an item is selected, it just gets painted the same as the model's
Background and Foreground roles was already telling it to.
