Member Function Documentation

◆ AddStyle()

virtual T iText.Layout.Element.AbstractElement< T >.AddStyle ( Style style )

inlinevirtual

Add a new style to this element.

Add a new style to this element. A style can be used as an effective way to define multiple equal properties to several elements, however its properties have lower priority than properties, directly set on iText.Layout.ElementPropertyContainer Note that if several Style objects are added, iText checks them one by one in the order in which they were added and returns the property's value from the last Style object, which contains this property. So, if there are two Style objects added: the first has set width of 100 points and the second of 200 points, iText will get 200 points as width value.

Parameters

style the style to be added

Returns: this element

◆ CreateRendererSubTree()

virtual IRenderer iText.Layout.Element.AbstractElement< T >.CreateRendererSubTree ( )

inlinevirtual

Creates a renderer subtree with root in the current element.

Creates a renderer subtree with root in the current element. Compared to GetRenderer() , the renderer returned by this method should contain all the child renderers for children of the current element.

Returns: a renderer subtree for this element

Implements iText.Layout.Element.IElement.

◆ GetChildren()

virtual IList<IElement> iText.Layout.Element.AbstractElement< T >.GetChildren ( )

inlinevirtual

Gets the child elements of this elements

Returns: a list of children

Implements iText.Layout.Element.IAbstractElement.

◆ GetProperty< T1 >()

override T1 iText.Layout.Element.AbstractElement< T >.GetProperty< T1 > ( int property )

inlinevirtual

Gets the property from this entity.

Gets the property from this entity. Compared to GetOwnProperty(int) , this method can check parent's properties, styles, etc, depending on the origin of the instance

Template Parameters

T1	the return type associated with the property

Parameters

property the property to be retrieved

Returns: the value of the given property. null will be returned if the property value was not found

Reimplemented from iText.Layout.ElementPropertyContainer< T >.

◆ GetRenderer()

virtual IRenderer iText.Layout.Element.AbstractElement< T >.GetRenderer ( )

inlinevirtual

Gets a renderer for this element.

Gets a renderer for this element. Note that this method can be called more than once. By default each element should define its own renderer, but the renderer can be overridden by SetNextRenderer(iText.Layout.Renderer.IRenderer) method call.

Returns: a renderer for this element

Implements iText.Layout.Element.IElement.

◆ HasProperty()

override bool iText.Layout.Element.AbstractElement< T >.HasProperty ( int property )

inlinevirtual

Checks if this entity has the specified property.

Checks if this entity has the specified property. Compared to HasOwnProperty(int) , this method can check parent's properties, styles, etc, depending on the origin of the instance

Parameters

property the property to be checked

Returns

true if this instance has given property, false otherwise

Reimplemented from iText.Layout.ElementPropertyContainer< T >.

◆ IsEmpty()

virtual bool iText.Layout.Element.AbstractElement< T >.IsEmpty ( )

inlinevirtual

Returns true if this list contains no elements.

Returns: true if this list contains no elements

◆ SetAction()

virtual T iText.Layout.Element.AbstractElement< T >.SetAction ( PdfAction action )

inlinevirtual

Sets an action on this Element.

Sets an action on this Element. An action is a general PDF concept that signifies anything that makes the document interactive, e.g. a hyperlink or a button.

Parameters

action the iText.Kernel.Pdf.Action.PdfAction that should be performed

Returns: this Element

◆ SetNextRenderer()

virtual void iText.Layout.Element.AbstractElement< T >.SetNextRenderer ( IRenderer renderer )

inlinevirtual

Overrides the iText.Layout.Renderer.IRenderer instance which will be returned by the next call to the GetRenderer().

Parameters

renderer the renderer instance

Implements iText.Layout.Element.IElement.

◆ SetPageNumber()

virtual T iText.Layout.Element.AbstractElement< T >.SetPageNumber ( int pageNumber )

inlinevirtual

Explicitly sets the page number this element should be put on.

Explicitly sets the page number this element should be put on. The location on the page will be the same as if it were added at the end of the document, but it will be located on the specified page.

This method should be used very carefully in client code.

Parameters

pageNumber the page number of the page this element should be placed on

Returns: this Element
