Customization of widgets.

Synopsis

Description

Styles are attached to widgets and determine how particular parts are drawn and with what color. Thus they are should be seen as mandatory when one implements a new custom widgets via DrawingArea. Although the parameterized drawing function don't have to be used, it is strongly advisable (and more robust) to make use of the predefined graphics contexts for the different states of a widget (retrieved by widgetGetState).

Methods

styleGetForeground :: Style -> StateType -> IO Color Source #

Retrieve the the foreground color.

The parameter state determines for which widget state (one of StateType) the Color should be retrieved. Use widgetGetState to determine the current state of the widget.

styleGetBackground :: Style -> StateType -> IO Color Source #

Retrieve the background color.

The parameter state determines for which widget state (one of StateType) the Color should be retrieved. Use widgetGetState to determine the current state of the widget.

styleGetLight :: Style -> StateType -> IO Color Source #

Retrieve a light color.

The parameter state determines for which widget state (one of StateType) the Color should be retrieved. Use widgetGetState to determine the current state of the widget.

styleGetMiddle :: Style -> StateType -> IO Color Source #

Retrieve a middle color.

The parameter state determines for which widget state (one of StateType) the Color should be retrieved. Use widgetGetState to determine the current state of the widget.

styleGetDark :: Style -> StateType -> IO Color Source #

Retrieve a dark color.

The parameter state determines for which widget state (one of StateType) the Color should be retrieved. Use widgetGetState to determine the current state of the widget.

styleGetText :: Style -> StateType -> IO Color Source #

Retrieve the text color.

The parameter state determines for which widget state (one of StateType) the Color should be retrieved. Use widgetGetState to determine the current state of the widget.

styleGetBase :: Style -> StateType -> IO Color Source #

Retrieve the base color.

The base color is the standard text background of a widget.
The parameter state determines for which widget state (one of StateType) the Color should be retrieved. Use widgetGetState to determine the current state of the widget.

styleGetAntiAliasing :: Style -> StateType -> IO Color Source #

Retrieve the color for drawing anti-aliased text.

The anti-aliasing color is the color which is used when the rendering of a character does not make it clear if a certain pixel shoud be set or not. This color is between the text and the base color.
The parameter state determines for which widget state (one of StateType) the Color should be retrieved. Use widgetGetState to determine the current state of the widget.
