Detailed Description

The QIconSelector class provides an icon-based combo box implementation.

QIconSelector operates similarly to a combo box but it has an important difference. It deals with information that is represented as both an icon and as text. The widget itself displays only icons while the pop-up selector displays both icon and text. This makes it suitable for placement in areas where there is limited horizontal space.

Here is a QIconSelector next to a text field. When down, it takes up very little room.

"QIconSelector"

Here is the pop-up selector. Both the icons and text are visible.
