Css.CssCompositeProperty Class Reference

Detailed Description

A CSS composite property. These are properties like background; one which is simply a shortform way of setting more than one property at the same time. Importantly, they are considered aliases. They do not actually enter the CSS style set because of this.

Public Member Functions
	CssCompositeProperty ()
CssPropertySetInfo	GetPropertySetInfo (CssProperty prop)
	In order to know when certain properties have been set and which have not, each property that a composite property updates has a 'set info' object. When reading a composite value, all the set info values are checked to see which ones were not set. It then proceeds to update those to their initial value. More...
override Css.Value	GetValue (Style styleBlock)
	Called to get a this properties value from the given style. This exists as it may be an alias property. More...
override void	OnReadValue (Style styleBlock, Css.Value value)
	Called when a value is read from the CSS stream. More...
Public Member Functions inherited from Css.CssPropertyAlias
	CssPropertyAlias ()
	CssPropertyAlias (CssProperty target, int[] index)
virtual int	RemapIndex (Css.Style style)
	Used to map a logical index to a physical one. More...
override Css.Value	GetValue (Style styleBlock)
	Called to get a this properties value from the given style. This exists as it may be an alias property. More...
override void	OnReadValue (Style styleBlock, Css.Value value)
	Called when a value is read from the CSS stream. More...
override Css.Value	GetOrCreateValue (Node context, Style styleBlock, bool allowInherit, out Css.Value hostValue)
	Called to get a this properties value from the given style. This exists as it may be an alias property. More...
Public Member Functions inherited from Css.CssProperty
virtual string[]	GetProperties ()
	The set of all properties that this one will handle. Usually just one. e.g. "v-align", "vertical-align". More...
virtual float	GetNormalValue (RenderableData context)
	The value of the 'normal' keyword. More...
CssProperty	GetAliased (int index)
	Gets the aliased property for the given index. E.g. color-r is index 0 of color. More...
CssProperty	GetAliased (int index, bool orThis)
	Gets the aliased property for the given index. E.g. color-r is index 0 of color. More...
virtual void	Aliases ()
	The set of aliases for this property. For example, the border-radius property can declare an alias of border-top-left which maps to e.g. "1", i.e. the first inner index. More...
virtual ApplyState	Apply (ComputedStyle style, Value value)
	Apply this CSS style to the given computed style. Note that you can grab the element from the computed style if you need that. More...
virtual void	ApplyText (TextRenderingProperty text, RenderableData data, ComputedStyle style, Value value)
	Apply this CSS style to the given computed style. Note that you can grab the element from the computed style if you need that. More...
Css.Value	GetOrCreateValue (Node context, Style styleBlock, bool allowInherit)
	Called to get a this properties value from the given style. This overload should not be used with alias properties - it always returns the 'host' value. More...
void	Reapply (ComputedStyle computed, string propertyName)
	Causes the named property to apply its value. More...
void	Reapply (ComputedStyle style, CssProperty property)
	Sets the named css property from the given style if the property exists in the style. More...
BackgroundImage	GetBackground (ComputedStyle style)
	Call this if the current property requires a background image object. More...
BorderProperty	GetBorder (ComputedStyle style)
	Call this if the current property requies a border object. More...
TextRenderingProperty	GetText (ComputedStyle style)
	Call this if the current property requires a text object. NOTE: This one may be null. More...
TextRenderingProperty3D	GetText3D (ComputedStyle style)
	Call this if the current property requires a text object. NOTE: This one may be null. More...
