View Full Version : QTreeWidgetItem background

16th September 2008, 13:24
QTreeWidgetItem *familyItem = new QTreeWidgetItem(fontTree);

familyItem->setText(0, family);
familyItem->setCheckState(0, Qt::Unchecked);
familyItem->setBackground(0,QColor(202, 0, 0, 255));

I want to color each item,but setbackground is changing only the color of first item.Any guess,why its not painting the item?.Looking for help

setBackground takes column as the first argument.
If you want to set color for the whole row, u will need to call setBackground on all columns :)

I guess you will need to iterate all items and set the color.

Other mehtod is to use delegates. I tried using it, but was not able to set the background color.
QTreeWidget uses delegates to render the items. I used QItemDelegate, but its drawBackground function was not being called. Only paint() was called. Also tried QStyledItemDelegate, but it doesnt have drawBackground function. Seems have to use paint() only.. :(

I will let u know if i succeed. its late now... gotta sleep
