Automatic Row Height in QTreeView

[michalos]

Hi,
Does anyone know how to automatically adjust a row height according to the width of the column, and the length of the text in it?
I have a QStandardItemModel with a tree structure.
I only have one column in each row.
At the start of the application, the height of each row is set correctly, but when I resize the widget(and the tree view) the heights of the rows are not recalculated.
I have a custom QStyledItemDelegate that draws the content, and calculates the sizeHint(), but it looks like the tree view only checks it when the model is set.
I've looked for a solution in this and other forums, but there doesn't seem to be an answer.
Everything works fine in a QTableView, but I need my model to be viewed as a tree.
Could anyone help me?

Ok. I've found the answer.

I subclass the QTreeView and override the void resizeEvent(QResizeEvent* e) as shown:

void MyTreeView::resizeEvent(QResizeEvent *e)
{
    if(model() != Q_NULLPTR){
        model()->layoutChanged();
    }
    QTreeView::resizeEvent(e);
}

And it did the trick.

Had help from the Voidrealms Facebook group.
