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
).
Types
class GObjectClass o => StyleClass o Source
castToStyle :: GObjectClass obj => obj -> Style Source
toStyle :: StyleClass o => o -> Style Source
Methods
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 ofStateType
) theColor
should be retrieved. UsewidgetGetState
to determine the current state of the widget.
