Detailed Description

A widget for previewing text formatting settings.

QgsTextPreview provides a widget for previewing the appearance of text rendered using QgsTextRenderer. The preview includes all settings contained within a QgsTextFormat, including shadow, background and buffer.

In order to preview the exact appearance of text which uses sizes in map units, the scale and map units must be set by calling setScale() and setMapUnits().
