@Tag("vaadin-horizontal-layout") @NpmPackage(value="@vaadin/horizontal-layout", version="25.0.0-alpha19") @JsModule("@vaadin/horizontal-layout/src/vaadin-horizontal-layout.js") public class HorizontalLayout extends com.vaadin.flow.component.Component implements ThemableLayout, FlexComponent, com.vaadin.flow.component.ClickNotifier<HorizontalLayout>
Horizontal Layout places components side-by-side in a row. By default, it has undefined width and height, meaning its size is determined by the components it contains.

    • setSpacing

      public void setSpacing(boolean spacing)
      Toggles spacing theme setting for the element. If a theme supports this attribute, it will apply or remove spacing to the element.

      This method adds medium spacing to the component theme, to set other options, use ThemableLayout.getThemeList(). List of options possible:

      • spacing-xs
      • spacing-s
      • spacing
      • spacing-l
      • spacing-xl

      Spacing is enabled by default for horizontal layout.

      Specified by:
      setSpacing in interface ThemableLayout
      Parameters:
      spacing - adds spacing theme setting if true or removes it if false

    • setVerticalComponentAlignment

      public void setVerticalComponentAlignment(FlexComponent.Alignment alignment, com.vaadin.flow.component.Component... componentsToAlign)
      Sets a vertical alignment for individual components inside the layout. This individual alignment for the component overrides any alignment set at the setDefaultVerticalComponentAlignment(Alignment).

      It effectively sets the "alignSelf" style value.

      The default alignment for individual components is FlexComponent.Alignment.AUTO.

      It's the same as the setAlignSelf(Alignment, HasElement...) method

      Parameters:
      alignment - the individual alignment for the children components. Setting null will reset the alignment to its default
      componentsToAlign - The components to which the individual alignment should be set
      See Also:

    • getVerticalComponentAlignment

      public FlexComponent.Alignment getVerticalComponentAlignment(com.vaadin.flow.component.Component component)
      Gets the individual vertical alignment of a given component.

      The default alignment for individual components is FlexComponent.Alignment.AUTO.

      It's the same as the getAlignSelf(HasElement) method.

      Parameters:
      component - The component which individual layout should be read
      Returns:
      the alignment of the component, never null
      See Also:

    • setDefaultVerticalComponentAlignment

      public void setDefaultVerticalComponentAlignment(FlexComponent.Alignment alignment)
      Sets the default vertical alignment to be used by all components without individual alignments inside the layout. Individual components can be aligned by using the setVerticalComponentAlignment(Alignment, Component...) method.

      It effectively sets the "alignItems" style value.

      The default alignment is FlexComponent.Alignment.STRETCH.

      It's the same as the setAlignItems(Alignment) method.

      Parameters:
      alignment - the alignment to apply to the components. Setting null will reset the alignment to its default
      See Also:

    • getDefaultVerticalComponentAlignment

      public FlexComponent.Alignment getDefaultVerticalComponentAlignment()
      Gets the default vertical alignment used by all components without individual alignments inside the layout.

      The default alignment is FlexComponent.Alignment.STRETCH.

      This is the same as the getAlignItems() method.

      Returns:
      the general alignment used by the layout, never null

    • setAlignItems

      public void setAlignItems(FlexComponent.Alignment alignment)
      This is the same as setDefaultVerticalComponentAlignment(Alignment).
      Specified by:
      setAlignItems in interface FlexComponent
