Detailed Description

A button for customizing QgsTextFormat settings.

The button will open a detailed text format settings dialog when clicked. An attached drop-down menu allows for copying and pasting text styles, picking colors for the text, and for dropping colors from other color widgets.

The button can be used in two different modes(). The default behavior is to include all settings used for configuring QgsTextFormat/QgsTextRenderer classes. A cut down mode (without settings for color) is also available when the resultant font is used only in a QFont object.
