Displaying a QStandardItem with its foreground color in a QTreeView even when it is selected

Using Qt 4.6.3 on Linux/X11.

I have a QTreeView widget which uses a QStandardItemModel as its model, with 4 columns and hundreds of rows. Most of the items in the list are to be displayed with a standard color, but a few need to be of a different color. I can change the colors of those few items easily with QStandardItem::setForeground().

However, that only affects the color of the item when it is not selected. When I select a colored item, its background color 开发者_高级运维changes to blue (which is ok), and the text color changes to white (which is not ok). I tried using a stylesheet to affect the foreground color of selected items (with selector QTreeView::item:selected), but it affects all items.

I would like items for which I called item->setForeground(Qt::red) to remain red even when they are selected, and other items to use the default set of colors (which they already do). How can that be done?

The colors being used are (I assume) those for the QPalette's Hightlight and HighlightedText roles. Unfortunately, I don't know of any way to set those on an individual standard item.

However, since standard items are used in the model/view framework, you have another option. You should be able to create a delegate to paint the view however you want to. I would recommend inheriting from the styled delegate, and calling the parent class's functionality as much as possible. Likely, you'll only need to change a few parameters in the cases where an item is selected and has a non-standard foreground color.
