| \brief The SystemPalette element provides access to the Qt palettes. |
| |
| The SystemPalette element provides access to the Qt application |
| palettes. This provides information about the standard colors used |
| for application windows, buttons and other features. These colors |
| are grouped into three \e {color groups}: \c Active, \c Inactive, |
| and \c Disabled. See the QPalette documentation for details about |
| color groups and the properties provided by SystemPalette. |
| |
| This can be used to color items in a way that provides a more |
| native look and feel. |
| |
| The following example creates a palette from the \c Active color |
| group and uses this to color the window and text items |
| appropriately: |
