 \class HbSearchPanel

 \brief The HbSearchPanel widget provides a common look and feel for inputting a search term.

 The searchPanel widget contains the following controls by default:

 \li search term input field

 \li cancel button

 The searchPanel may contain the following optional controls depending on the properties:

 \li ok button

 \li searchOptions button

 The ok button exists when progressive property is false. The ok button emits criteriaChanged()

 when the button is clicked. By default progressive property is true and the ok button is not

 available.

 The searchOptions button exists when searchOptions property is true. The searchOptions button

 emits searchOptionsClicked() when the button is clicked. By default searchOptions property is

 false.

 An example how to create HbSearchPanel with non-progressive mode and searchOptions button

 available.
