StyleSet Class

아티클

A StyleSet is a collection of graphics objects that can be used by an application to specify a set of pens, brushes, and fonts to be used for all of the drawing operations. Within the painting code, you can call StyleSet.GetPen to retrieve a specific pen defined by the system. That pen will be set to the correct color and style defined with the application. Use that pen immediately as it is unique. If you need to hold onto a pen use GetPenCopy. StyleSets can live at multiple levels in the system. There's an ApplicationStyleSet which are the app defined defaults style scheme. There are also ClassStyleSets which exist at the class type level to specify styles for all instances of that class of shape. There can also exist instance StyleSets which contains resource information for each instance of a shape. This should be used when different instances of the same class of shapes can have different appearance. When actually trying to retrieve an object, like a Pen, the StyleSet code goes up the inheritance chain from instance to class to application StyleSets until if finds that first one that contains that resource that you're looking for (as defined by the ResourceId that you're asking for).

Methods

	Name	Description
	AddBrush	Add a new Brush to this StyleSet.
	AddFont	Add a new Font to this StyleSet.
	AddPen	Add a new Pen to this StyleSet.
	ClearBrushOverride	Clears an overriden Brush in the StyleSet.
	ClearFontOverride	Clears an overriden Font in the StyleSet.
	ClearPenOverride	Clears an overriden Pen in the StyleSet.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetBrush	Retrieves a specific Brush from the StyleSet. If it's not in the current one, it looks up the parent chain to see if it can find it there. This is a singleton. Do not dispose - this will crash! Use immediately. Use GetBrushCopy if another brush is needed!
	GetBrushCopy	Retrieves a specific Brush from the StyleSet. If it's not in the current one, it looks up the parent chain to see if it can find it there. This is a copy. Caller is responsible for dispose.
	GetFont	Retrieves a specific Font from the StyleSet. If it's not in the current one, it looks up the parent chain to see if it can find it there.
	GetFontHeight	Returns the line spacing of the specified font (i.e., the height of a line of text) in world units. Line spacing is the ascent + the descent + some recommended extra. The ascent is the height of the character above the baseline, and the descent is the height of the character below the baseline. The extra is below the descent.
	GetFontSize	Returns the em height of the font with the specified id. This is the value specified when the font was created. Use GetFontHeight instead to get the height of a line of text when using this font.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetOverriddenBrushSettings	Gets a BrushSettings object containing settings which have been overriden in this style set. If no settings have been overriden, this method returns null.
	GetOverriddenFontSettings	Gets a FontSettings object containing settings which have been overriden in this style set. If no settings have been overriden, this method returns null.
	GetOverriddenPenSettings	Gets a PenSettings object containing settings which have been overriden in this style set. If no settings have been overriden, this method returns null.
	GetPen	Retrieves a specific Pen from the StyleSet. If it's not in the current one, it looks up the parent chain to see if it can find it there. This is a singleton. Do not dispose - this will crash! Use immediately. Use GetPenCopy if another pen is needed!
	GetPenCopy	Retrieves a specific Pen from the StyleSet. If it's not in the current one, it looks up the parent chain to see if it can find it there. This is a copy. Caller is responsible for dispose.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OverrideBrush	Overrides the specified Brush in the StyleSet.
	OverrideBrushWorker	Overrides the specified Brush in the StyleSet.
	OverrideFont	Overrides the specified Font in the StyleSet.
	OverrideFontWorker	Overrides the specified Font in the StyleSet.
	OverridePen	Overrides the specified Pen in the StyleSet.
	OverridePenWorker	Overrides the specified Pen in the StyleSet.
	RefreshResources	Forces a re-resolution of the resources if necessary. The resources are resolved later when used.
	RemoveBrush	Removes a Brush from this StyleSet.
	RemoveFont	Removes a Font from this StyleSet.
	RemovePen	Removes a Pen from this StyleSet.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
