selection color of the items delegated in a tree widget

[fulbay]

If "row" item is selectable on the tree widget, when the row is selected, the row is highlighted, that is, it is colored with a color (blue as default). If the tree widget has some delegated items (like comboboxes, spinboxes), the delegated items do not seem as if they were selected - they are not highlighted -.

How can we handle this? I mean, when I select the row, I want all the items to have been selected, and also, when I select a delegated item, I want the row item to have been selected. Is the only way to implement it via signal & slot mechanism? I mean, if one delegate item is clicked, the row and all the delegated items included should go into 'selected' status and vice versa (if the tree widget is selected, all the delegate items are selected.).

Thanks for your guidance...
