Prevent QStyledItemDelegate from drawing focus rectangle

**stefanadelbert** · 15th July 2010, 02:32

I would like to prevent my derived QStyledItemDelegate from painting the focus rectangle.

I have achieved this before using a QItemDelegate by overriding its drawFocus function and doing nothing.

However QStyledItemDelegate does not implement drawFocus. Is there another way to prevent the QStyledItemDelegate from not painting the focus rectangle?

In the paint function of your custom QStyledItemDelegate class -

Qt Code:

Switch view

QStyleOptionViewItem newOption = option;
newOption.state = option.state & (~QStyle::State_HasFocus);
QStyledItemDelegate::paint(painter,newOption,index);

QStyleOptionViewItem newOption = option;
newOption.state = option.state & (~QStyle::State_HasFocus);
QStyledItemDelegate::paint(painter,newOption,index);

To copy to clipboard, switch view to plain text mode

Hi,

please also note our search function, because this question is asked every month...

But why I am replying is, because I wonder what is "better" or if there is a significant difference between
making a local copy of option as above
and
casting the const of option away?

I guess depends on habit too. I usually wont prefer to break something that wasn't meant to be broken.
