Detailed Description

A widget for customizing text formatting settings.

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

Additionally, the widget can handle labeling settings due to the large overlap between the text renderer settings and the labeling settings. This mode is possible by subclassing QgsTextFormatWidget and calling the protected constructor with a mode of Labeling.
