void addResource	(	Widget &	widget,
		const std::string &	resources
	)

overridevirtual

Parses a resource description string.

Parameters

widget	Widget to associate resources with.
resources	String describing the style resources.

Implements lysa::ui::Style::addResource()

virtual float borderSize ( ) const

inlineprotectedvirtual

Size of the borders inserted by resize() around the content of the bordered widgets.

Expressed in vertical units but applied to both axes, so it eats into the width of a widget far more than into its height : the horizontal unit is compressed by the aspect ratio. Keep it small, an icon button is barely a dozen units wide.

virtual std::string buttonResource ( ) const

virtual

Resource string of a push button.

virtual std::string checkMarkResource ( ) const

virtual

Resource string of the mark of a check box.

Reimplemented in lysa::ui::StyleMaterial::checkMarkResource()

virtual std::string containerResource ( ) const

virtual

Resource string of a sunken container (list boxes, tree views, text areas)

Reimplemented in lysa::ui::StyleMaterial::containerResource()

virtual float4 disabledTextColor ( ) const

void draw	(	const Widget &	widget,
		UIResource &	resources,

	)		const

overridevirtual

Draws a widget by dispatching on its Widget::Type.

Parameters

widget	Widget to draw.
resources	Resources used for drawing.
renderer	The 2D renderer.
before	True when called before drawing children, false after.
