Methods

ArrangeOverride(SizeF)

Arranges the LayoutElement to its final location. The element must call the Arrange method of each of its children.

C#
protected override SizeF ArrangeOverride(SizeF finalSize)
Parameters:finalSizeSizeF

The size that is available for element.

Returns:

SizeF

The rectangle occupied by the element. Usually finalSize. Should you return different size, the Layout system will restart measuring and rearranging the items. That could lead to infinite recursion.

Overrides: LayoutElement.ArrangeOverride(SizeF)

Remarks:

In this method call to the Arrange method of each child must be made.

CreateLayoutBoxesFromContent()

C#
protected void CreateLayoutBoxesFromContent()

CreateLayoutElement()

Creates a layout element for the paragraph within the layout box.

C#
public override LayoutElement CreateLayoutElement()
Returns:

LayoutElement

Overrides: LayoutBox.CreateLayoutElement()

CreateNewFragment(LayoutBox)

Creates a new fragment within the specified layout box.

C#
public override void CreateNewFragment(LayoutBox currentLineStartNode)
Parameters:currentLineStartNodeLayoutBox

The layout box in which the new fragment will be created.

Overrides: LayoutBox.CreateNewFragment(LayoutBox)

GetPositionHandler()

Retrieves the position of the layout box for the current paragraph.

C#
public override PositionHandler GetPositionHandler()
Returns:

PositionHandler

A Point representing the position of the paragraph layout box.

Overrides: LayoutBox.GetPositionHandler()

InvalidateLongWordsFragmentation()

Invalidates the long words fragmentation for the paragraph layout box. This method recalculates the layout of the paragraph to ensure that long words are rendered correctly, avoiding overflow and maintaining the visual integrity of the text.

C#
public void InvalidateLongWordsFragmentation()

MeasureOverride(SizeF)

Measures the space required by the LayoutElement Used by the layout system.

C#
protected override SizeF MeasureOverride(SizeF availableSize)
Parameters:availableSizeSizeF

The size that is available to the LayoutElement. The available size can be infinity (to take the full size of the element)

Returns:

SizeF

The minimum size required by the element to be completely visible. Cannot be infinity.

Overrides: LayoutElement.MeasureOverride(SizeF)

Remarks:

In this method call to the Measure method of each child must be made.

OnInvalidateMeasure()
