Renders the delegate using the given painter and style option for the item specified by index.
When reimplementing this function in a subclass, you should update the area held by the option's rect variable, using the option's state variable to determine the state of the item to be displayed, and adjust the way it is painted accordingly.
For example, a selected item may need to be displayed differently to unselected items, as shown in the following code:
...
After painting, you should ensure that the painter is returned to its the state it was supplied in when this function was called. For example, it may be useful to call QPainter::save() before painting and QPainter::restore() afterwards.

inlineprotectedvirtual |
Returns the size needed by the delegate to display the item specified by index, taking into account the style information provided by option.
When reimplementing this function, note that in case of text items, QItemDelegate adds a margin (i.e. 2 * QStyle::PM_FocusFrameHMargin) to the length of the text.
