LineBreak Class

Definition

Namespace:

Microsoft.UI.Xaml.Documents

Represents an inline element that causes a new line to begin in content when rendered in a text container.

Remarks

LineBreak is most commonly used when formatting text within the TextBlock.Inlines collection. RichTextBlock supports the Paragraph element as an element that separately renders text blocks, so you don't typically need to use LineBreak content as often. (LineBreak is supported in the RichTextBlock text model, for example you can place a LineBreak in Paragraph.Inlines, between other Run or Span elements, and a line break will render at that position.)

LineBreak inherits properties from the TextElement class. However, most of these properties don't have any visible effect. It's most common to declare a LineBreak object element in XAML without there being any attributes set, similar to how you might use a <br/> tag in HTML.

Setting properties on LineBreak that otherwise affect the character line height of a text element (such as FontSize, FontFamily) has no effect on the text rendering and appearance. The height of a text line is inferred from the other text elements that precedes the LineBreak, and the properties of a LineBreak don't modify that line height even if set explicitly.

Constructors

LineBreak()

Initializes a new instance of the LineBreak class.

Properties

AccessKey	Gets or sets the access key for this element. (Inherited from TextElement)
AccessKeyScopeOwner	Gets or sets a source element that provides the access key scope for this element, even if it's not in the visual tree of the source element. (Inherited from TextElement)
AllowFocusOnInteraction	Gets or sets a value that indicates whether the element automatically gets focus when the user interacts with it. (Inherited from TextElement)
CharacterSpacing	Gets or sets the uniform spacing between characters, in units of 1/1000 of an em. (Inherited from TextElement)
ContentEnd	Gets a TextPointer that represents the end of the content in the element. (Inherited from TextElement)
ContentStart	Gets a TextPointer that represents the start of content in the element. (Inherited from TextElement)
Dispatcher	Always returns null in a Windows App SDK app. Use DispatcherQueue instead. (Inherited from DependencyObject)
DispatcherQueue	Gets the DispatcherQueue that this object is associated with. The DispatcherQueue represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject)
ElementEnd	Gets a TextPointer that represents the position just after the end of the element. (Inherited from TextElement)
ElementStart	Gets a TextPointer that represents the position just before the start of the element. (Inherited from TextElement)
ExitDisplayModeOnAccessKeyInvoked	Gets or sets a value that specifies whether the access key display is dismissed when an access key is invoked. (Inherited from TextElement)
FontFamily	Gets or sets the preferred top-level font family for the content of the element. (Inherited from TextElement)
FontSize	Gets or sets the font size for the content of the element. (Inherited from TextElement)
FontStretch	Gets or sets the glyph width of the font in a family to select. (Inherited from TextElement)
FontStyle	Gets or sets the font style for the content in this element. (Inherited from TextElement)
FontWeight	Gets or sets the top-level font weight to select from the font family for the content in this element. (Inherited from TextElement)
Foreground	Gets or sets the Brush to apply to the content in this element. (Inherited from TextElement)
IsAccessKeyScope	Gets or sets a value that indicates whether an element defines its own access key scope. (Inherited from TextElement)
IsTextScaleFactorEnabled	Gets or sets whether automatic text enlargement, to reflect the system text size setting, is enabled. (Inherited from TextElement)
KeyTipHorizontalOffset	Gets or sets a value that indicates how far left or right the keytip is placed in relation to the text element. (Inherited from TextElement)
KeyTipPlacementMode	Gets or sets a value that indicates where the KeyTip is placed in relation to the text element. (Inherited from TextElement)
KeyTipVerticalOffset	Gets or sets a value that indicates how far up or down the keytip is placed in relation to the text element. (Inherited from TextElement)
Language	Gets or sets localization/globalization language information that applies to a TextElement. (Inherited from TextElement)
Name	Gets or sets a unique identification for the object. Name can only be set from initial parsing of XAML. (Inherited from TextElement)
TextDecorations	Gets or sets a value that indicates what decorations are applied to the text. (Inherited from TextElement)
XamlRoot	Gets or sets the XamlRoot in which this element is being viewed. (Inherited from TextElement)

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
FindName(String)	Retrieves an object in the object model / runtime object graph by referencing the object's x:Name or Name attribute value. (Inherited from TextElement)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
OnDisconnectVisualChildren()	Override this method to implement how layout and logic should behave when items are removed from a class-specific content or child property. (Inherited from TextElement)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)

Events

AccessKeyDisplayDismissed	Occurs when the access key sequence is complete to notify controls that they should hide access key visuals. (Inherited from TextElement)
AccessKeyDisplayRequested	Occurs when the access key sequence is started to notify controls that they should show access key visuals. (Inherited from TextElement)
AccessKeyInvoked	Occurs when a user completes an access key sequence to notify the element that the access key action should be invoked. (Inherited from TextElement)
