Displaying Glyphs

  • 8 minutes to read

You can display icons within bar items. Such icons are called glyphs. This topic explains how to display glyphs and configure their appearance, and contains the following sections.

Specifying Glyphs

To specify a bar item’s glyph, use the BarItem.Glyph and BarItem.LargeGlyph properties. The resulting glyph depends on the available space.

The following example demonstrates a toolbar that displays large glyphs and a submenu that displays small glyphs.

<Window ...
        xmlns:dxb="http://schemas.devexpress.com/winfx/2008/xaml/bars"
        xmlns:dxc="http://schemas.devexpress.com/winfx/2008/xaml/core" >
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>
        <dxb:ToolBarControl Grid.Row="0" VerticalAlignment="Top">
            <dxb:BarButtonItem Name="itemCut" Content="Cut" Glyph="{dxc:DXImage Image=Cut_16x16.png}" LargeGlyph="{dxc:DXImage Image=Cut_32x32.png}"/>
            <dxb:BarButtonItem Name="itemCopy"  Content="Copy" Glyph="{dxc:DXImage Image=Copy_16x16.png}" LargeGlyph="{dxc:DXImage Image=Copy_32x32.png}"/>
            <dxb:BarButtonItem Name="itemPaste" Content="Paste" Glyph="{dxc:DXImage Image=Paste_16x16.png}" LargeGlyph="{dxc:DXImage Image=Paste_32x32.png}"/>
            <dxb:BarSubItem Content="SubItem" Glyph="{dxc:DXImage Image=Properties_16x16.png}" LargeGlyph="{dxc:DXImage Image=Properties_32x32.png}">
                <dxb:BarButtonItemLink BarItemName="itemCut"/>
                <dxb:BarButtonItemLink BarItemName="itemCopy"/>
                <dxb:BarButtonItemLink BarItemName="itemPaste"/>
            </dxb:BarSubItem>
        </dxb:ToolBarControl>
    </Grid>
</Window>

The following image demonstrates the result.

Specifying Glyphs

Glyph Display Mode

You can specify the glyph visibility for individual bar items or entire toolbars and menus using the BarItemDisplayMode properties. The display mode specified for a child object overrides the display mode of a parent. The following table lists the properties that control the display mode of bar items. Properties that have the highest precedence are listed first.

Property Description
BarItemLinkBase.BarItemDisplayMode Specifies the glyph visibility for an individual bar item link represented by a BarItemLink descendant.
BarItem.BarItemDisplayMode Specifies the glyph visibility for an individual bar item represented by a BarItem descendant.
Bar.BarItemDisplayMode Specifies the glyph visibility for all items within theBar container.
ToolBarControlBase.BarItemDisplayMode Specifies glyph visibility for all items within a container represented by a ToolBarControlBase descendant.
BarContainerControl.BarItemDisplayMode Specifies the glyph visibility for all items within the BarContainerControl.

The BarItemDisplayMode property must be set to one of the BarItemDisplayMode enumeration values. The following table lists the available options.

BarItemDisplayMode

property value

Bar item appearance

Default

Bar items display a glyph within toolbars.

Bar items display both content and glyph within menus and ribbon.

Content

Bar items display content only.

ContentAndGlyph

Bar items display both content and glyph.

Note

If the BarItemDisplayMode property is set for a container and an item within this container has the Default display mode, the container’s BarItemDisplayMode value is used for the item.

The following example demonstrates glyph visibility customizations and the BarItemDisplayMode property precedence.

Specifying Glyph Visibility

Glyph Size

If you assign both small and large glyphs to a bar item, you can specify the glyph size explicitly.

The following table lists properties that allow you to specify the required glyph size for bar items and item containers.

Property

Description

BarItem.GlyphSize

Specifies the glyph size for a specific bar item represented by an instance of BarItem or its descendant.

Bar.GlyphSize

Specifies the glyph size for all items within the Bar container.

ToolBarControlBase.GlyphSize

Specifies the glyph size for all bar items within a container that is a ToolBarControlBase descendant.

BarLinkContainerItem.SubItemsGlyphSize

Specifies the glyph size for all subitems within the BarLinkContainerItem container and its descendants.

BarSubItem.SubItemsGlyphSize

Specifies the glyph size for all bar items within the BarSubItem container.

BarManager.ToolbarGlyphSize

Specifies the glyph size for toolbar items within the BarManager container.

BarManager.MenuGlyphSize

Specifies the glyph size for menu items within the BarManager container.

BarItem.GlyphSize

(via RibbonGalleryBarItem.GlyphSize)

Specifies the glyph size for items within the RibbonGalleryBarItem.DropDownMenuItems collection.

The GlyphSize properties must be set to one of the GlyphSize enumeration values. The following table lists the available options.

GlyphSize property value

Resulting glyph

Default

In toolbars, bar items display large glyphs.

In menus, bar items display small glyphs.

Large

A bar item displays a glyph specified by the BarItem.LargeGlyph property.

Small

A bar item displays a glyph specified by the BarItem.Glyph property.

Custom

The glyph size is specified by the Size value.

See Custom glyph size to learn more.

Note

If the GlyphSize property is set for a container and an item within this container has the Default glyph size, the container’s GlyphSize value is used for the item.

The following example demonstrates the GlyphSize property precedence.

Specifying glyph size

Custom Glyph Size

If the GlyphSize property is set to Custom, you can set the exact width and height of the bar item’s glyph. To specify a custom glyph size, assign a Size value to one of the CustomGlyphSize properties.

The following table lists properties that allow you to specify the custom glyph size. Properties that have the highest precedence are listed first.

Property

Description

BarItemLinkBase.CustomGlyphSize

Specifies the exact width and height of the BarItemLink‘s glyph.

BarItem.CustomGlyphSize

Specifies the exact width and height of the BarItem‘s glyph.

ILinksHolder.CustomItemsGlyphSize

Specifies the exact width and height of the glyph for all bar items within a container that is the ILinksHolder implementation.

BarItemLinkHolderBase.CustomItemsGlyphSize

Specifies the exact width and height of the glyph for all bar items within a container that is a BarItemLinkHolderBase descendant.

BarLinkContainerItem.SubItemsCustomGlyphSize

Specifies the exact width and height of the glyph for all bar items within the BarLinkContainerItem container and its descendants.

BarSubItem.SubItemsCustomGlyphSize

Specifies the exact width and height of the glyph for all bar items within the BarSubItem container.

BarItem.CustomGlyphSize

(via RibbonGalleryBarItem.CustomGlyphSize)

Specifies the exact width and height of the glyph for items within the RibbonGalleryBarItem.DropDownMenuItems collection.

The following example illustrates the bar item glyph size customization capabilities.

Hide and Display Glyphs in Popup Menus

Use the BarManager.ShowGlyphsInPopupMenus attached property to display or hide the popup bar item’s glyph.

You can apply the BarManager.ShowGlyphsInPopupMenus attached property for the following items:

Note

Applying the BarManager.ShowGlyphsInPopupMenus attached property to individual items in a popup menu does not cause any changes.

When setting the property on BarSplitButtonItem and on the nested PopupMenu, the value set on the popup menu has the higher priority.

The BarManager.ShowGlyphsInPopupMenus attached property value is not taken into account in the following cases.

  • Showing items in the radial menu.
  • Showing items horizontally in the simple popup menu (using the BarItemMenuHeader with the Orientation property set to Horizontal).

Tip

You can use the BarManager.ShowGlyphsInPopupMenus property to hide the space reserved for the menu item glyphs when the items’ glyphs are not specified.

Bars_ShowGlyphsInPopupMenus

The following example demonstrates the BarManager.ShowGlyphsInPopupMenus property set for a BarSubItem object.
