Hi,
I am experimenting with qTreeWidget and change something in the look;

1) how change text look only for the parent item? i have used the following code for rendering a bold text:

#include <QApplication>
#include <QTreeWidgetItem>
#include <QFont>

class TreeWidget : public QTreeWidget
{
protected:
void drawRow(QPainter *, const QStyleOptionViewItem &, const QModelIndex &) const;
};

void TreeWidget::drawRow(QPainter *painter, const QStyleOptionViewItem & option, const QModelIndex & index ) const
{
QFont serifFont("Times", 11);
serifFont.setBold(true);

QStyleOptionViewItem myopt(option);
myopt.font = serifFont;
QTreeView::drawRow(painter, myopt, index);
}

int main( int argc, char **argv )
{
QApplication app( argc, argv );
TreeWidget *tree = new TreeWidget();
tree->setColumnCount(2);

QTreeWidgetItem *item = new QTreeWidgetItem(tree,0);
item->setText(0, "Parent");
item->setText(1, "Parent description");

QTreeWidgetItem *item2 = new QTreeWidgetItem(item,1);
item2->setText(0, "Child");
item2->setText(1, "child description");
tree->show();

return app.exec();
}

but parent and child are both in bold.

2) How change the default expand/collapse symbols with custom images?

Thanks,
Giuseppe

Hi junior,
thanks for your help; your code is what i need (in row 3 and 7 is missing the column number as parameter of the functions font() and setFont()).

The other question is unsolved; among available sub-controls in style sheets nothing is related to qtreewidget.

Bye,
Giuseppe

I was wrong when in the previous post i said that stylesheet hasn't a subcontrol; it is ::branch.

I have added these 2 rows to the code above:



Thanks to Junior and lifthrasir for the precious help.

Here I am again; this time with question #1 for qtreeview.
How can i format a bold text for a parent item in qtreeview?
I have created and populated a model which is passed to treeView.
I was able changing the branch with stylesheet but no luck in changing font weight.

As usual , thanks
Giuseppe
