TSVGElement Class

Create(TSVGDocument)

Initializes a new instance of the TSVGElement class.

Destroy

Represents the destructor of the TSVGElement class.

Attributes

Represents property Attributes.

BoundsRect

Returns the bounding rectangle for the SVG element unmodified by any transformations

To retrieve the "true" bounding rectangle which has been modified by any transformations, use the GetBoundsRect method

Classes

Specifies the 'classes' that the SVG element belongs to. The classes property assigns one or more class names to an element. The element may be said to belong to these classes. A class name may be shared by several element instances.

Description

Specifies a non-visual Description for the SVG element. When generating FMX controls, the FMX control's Hint property is set to the Description. If the Description is empty, the Hint is set to the Title

ID

Unique name for the SVG element. The SVG document's   AllItems property uses the ID as the unique hash for returning SVG elements

Items

The child SVG Items of the current element. The Parent and Items properties define the hierarchy of a SVG document fragment.

Language

Specifies the Language of the SVG element

Owner

Returns the Owner SVG document for the SVG element.

Parent

The Parent SVG Element of the current element. The Parent and Items properties define the hierarchy of a SVG document fragment.

RequiredExtensions

Specifies a list of required language extensions. Language extensions are capabilities within a user agent that go beyond the feature set defined in this specification. Each extension is identified by an IRI reference.

The RSCL supports no extensions.

RequiredFeatures

Defines a list of feature strings. Determines whether all of the named features are supported by the RSCL.

SystemLanguages

Specifies a list of language names as defined in BCP 47

Title

Specifies a non-visual Title of the SVG element. When generating FMX controls, the FMX control's Hint property is set to Title if the Description property is empty

UpdateCount

Represents property UpdateCount.

ApplyStyles

Applies all styles that match the element to the element. All child elements also have their styles applied.

Assign(TPersistent)

Represents method Assign(TPersistent).

AssignProperties(TPersistent)

Copies the properties of source to the current element (but not children)

AssignTo(TPersistent)

Represents method AssignTo(TPersistent).

BeginUpdate

Marks the start of an update session of the element and its children.
 
No change events occur after the BeginUpdate call. A call to BeginUpdate must be complemented by calls to EndUpdate after the update is finished.
 
 

Change

Represents method Change.

Clear

Clears the SVG element and resets its properties back to their defaults

Clone(TSVGDocument)

Clones the element and all of its child elements. The aOwner parameter should be a different document

CreateControl(TControl)

Represents method CreateControl(TControl).

DoLoadFromXML(IXMLNode)

Represents method DoLoadFromXML(IXMLNode).

DoModifyControl(TControl,TSVGMatrix,TRSRect,TSVGControlElementEvent)

Represents method DoModifyControl(TControl,TSVGMatrix,TRSRect,TSVGControlElementEvent).

DoOnParsedNode(TSVGElement)

Represents method DoOnParsedNode(TSVGElement).

DoOnParsingNode(TSVGElement,IXMLNode)

Represents method DoOnParsingNode(TSVGElement,IXMLNode).

Draw(TCanvas,TRect)

Overloaded. Draw the SVG to the specified canvas inside the specified rectangle

Draw(TSVGCanvas,TSVGRect)

Overloaded. Draw the SVG to the specified canvas inside the specified rectangle

ElementNotification(TObject,TSVGElement,TCollectionNotification)

Represents method ElementNotification(TObject,TSVGElement,TCollectionNotification).

EndUpdate

Marks the end of an update session of the element and its children.
 
The update session must be started first by calling BeginUpdate.
 
EndUpdate decreases a updating semaphore. If all update sessions end and the semaphore is 0, EndUpdate signals a OnChange event.
 

FitToRect(TSVGRect)

Overloaded. Returns a transformation matrix that will properly scale and translate the SVG element's   BoundsRect so that it fits within the input rectangle

FitToRect(TSVGRect,TSVGRect)

Overloaded. Returns a transformation matrix that will properly scale and translate the TargetRect so that it fits within the input rectangle

GenerateChildControls(TControl,TSVGMatrix,TRSRect,TSVGControlElementEvent)

Represents method GenerateChildControls(TControl,TSVGMatrix,TRSRect,TSVGControlElementEvent).

GenerateControls(TControl,TRSRect,TSVGControlElementEvent)

Overloaded.  Generates FMX controls to represent this SVG element and its children. The Parent parameter specifies the parent control for the generated FMX control.

The FMX control is transformed by a matrix returned from the GetViewMatrix function

GenerateControls(TControl,TSVGMatrix,TRSRect,TSVGControlElementEvent)

Overloaded. Generates FMX controls to represent this SVG element and its children. The Parent parameter specifies the parent control for the generated FMX control.

GetBoundsRect

Overloaded. Represents method GetBoundsRect.

GetBoundsRect(TSVGMatrix)

Overloaded. Returns the "true" BoundsRect where the boundaries of the element are modified by the input matrix plus (for graphic elements) its transformation Matrix

GetNearestViewBox

Returns the nearest ancestor (Parent, or Parent of Parent, or etc) element that is a TSVGCustomViewBox element

GetUnitFactors

Represents method GetUnitFactors.

GetViewMatrix(TRect)

Overloaded. Returns a transformation matrix for viewing this element

GetViewMatrix(TSVGMatrix,TRect)

Overloaded. Returns a transformation matrix for viewing this element

GetViewMatrix(TSVGMatrix,TSVGRect)

Overloaded. Returns a transformation matrix for viewing this element

GetViewMatrix(TSVGRect)

Overloaded. Returns a transformation matrix for viewing this element

HasAncestor(TSVGElement)

Returns true if the input element is an ancestor of the current SVG element

HasChild(TSVGElement)

Returns true if the input element is a direct child of the current SVG element

HasDescendant(TSVGElement)

Returns true if the input element is a descendant of the current SVG element

HasExtensions

Returns true if the required extensions are present. The RSCL supports no extensions at this time, if RequiredExtensions is not empty, this method will return False

HasFeatures

Returns true if the Owner document supports all of the features of the element. If all of the given features are supported, then the function evaluates to true; otherwise, the current element and its children are skipped and thus will not be rendered.

HasFollowing(TSVGElement)

Returns true if the input element follows the current SVG element

HasLanguage(String)

Returns True if the Language property matches the language IDs in the input parameter. Multiple languages can be specified by separating the language IDs with commas and/or spaces.

HasLanguages

Returns True if the Owner SVG document fragment supports the Language property or one of the SystemLanguages

HasPreceding(TSVGElement)

Returns true if the input element precedes the current SVG element

HasSibling(TSVGElement)

Returns true if the input element is a sibling (share same Parent) of the current SVG element

LoadFromXML(IXMLNode)

Loads the SVG element's attributes and child nodes from the XML node

Matches(String)

Returns the specificity (>=0) of the match with the selector string or -1 if there is no match.

A selector's specificity is calculated as follows:

ControlConstructor

Represents field ControlConstructor.

FAttributes

Represents field FAttributes.
