Name

Description

public property

Attributes

Represents property Attributes. (Inherited from RSSVG.TSVGElement.)

public property

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

published property

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. (Inherited from RSSVG.TSVGElement.)

published property

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 (Inherited from RSSVG.TSVGElement.)

published property

ID

Unique name for the SVG element. The SVG document's   AllItems property uses the ID as the unique hash for returning SVG elements (Inherited from RSSVG.TSVGElement.)

public method

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:

1. Count the number of ID selectors in the selector (= a)
2. Count the number of class selectors, attributes selectors, and pseudo-classes in the selector (= b)
3. Count the number of type selectors and pseudo-elements in the selector (= c)
4. Ignore the universal selector
5. Selectors inside the negation pseudo-class are counted like any other, but the negation itself does not count as a pseudo-class.


















Concatenating the three numbers a-b-c (in a number system with a large base) gives the specificity.
