QTreeView selection Style ?

[jpujolf]

Anybody knows how to make selected cell in a row look like this with StyleSheets ? I'm been trying but no success...

I'm using QTreeViews, with row selection. A very thin dotted line appears by default, but I want a more evident rectangle.

try:

QTreeView::item:selected
{
 background-color:transparent;
 color:blue;
}

QTreeView::item:selected
{
 background-color:transparent;
 color:blue;
}

To copy to clipboard, switch view to plain text mode

Thanks, but doesn't work.

ALL cells on the row are in blue, because selection is QAbstractItemView::SelectRows.

I only want the one is selected and focused ( Qt paints a thin dotted line around it ).

that is possible in QTableView

I haven't tested it, but if you make this call :

setSelectionBehavior (QAbstractItemView::SelectRows );

setSelectionBehavior (QAbstractItemView::SelectRows );

To copy to clipboard, switch view to plain text mode 

Is still working ? Anyway, I'm forced to use QTreeView, cannot use QTableView. As I show in the capture screen, my data has a tree structure.

Hi, Will delegates suit you ?
you can try the following -

class ItemDelegate : public QItemDelegate
{
public:
void paint(QPainter *painter,
                          const QStyleOptionViewItem &option,
                          const QModelIndex &index) const
{
    QItemDelegate::paint(painter,option,index);
    if(option.state & QStyle::State_HasFocus)
    {
        painter->save();
        QPen pen = QPen(Qt::green);
        pen.setWidth(2);
        painter->setPen(pen);
        painter->drawRect(option.rect.adjusted(1,1,-1,-1));
        painter->restore();
    }
}
};

class ItemDelegate : public QItemDelegate
{
public:
void paint(QPainter *painter,
                          const QStyleOptionViewItem &option,
                          const QModelIndex &index) const
{
    QItemDelegate::paint(painter,option,index);
    if(option.state & QStyle::State_HasFocus)
    {
        painter->save();
        QPen pen = QPen(Qt::green);
        pen.setWidth(2);
        painter->setPen(pen);
        painter->drawRect(option.rect.adjusted(1,1,-1,-1));
        painter->restore();
    }
}
};

Just set it on your treeview / tree widget.
It works ,, I tested it..

May be you can try with style sheet too... try focus instead of selected.

As usual, I've made a KISS ( Keep It Simple Stupid ), so setting this in the styleSheet works like a charm !!

QTreeView::item:focus
{
  background-color:transparent;
  color:blue;
}

QTreeView::item:focus
{
  background-color:transparent;
  color:blue;
}

To copy to clipboard, switch view to plain text mode 

Thanks a lot !!

jpujolf, how did you make root elements to draw different background?

[jpujolf]

I've done it by overloading QVariant QAbstractItemModel::data ( const QModelIndex & Index, int Role ) const
with role Qt::BackgroundRole. Not all can be done with stylesheets...
