What is the point of the StatusBarItem class in WPF?
How is the StatusBarItem
class supposed to be used? Is every element in a StatusBar
's content supposed to be wrapped with it?
I don't really understand how StatusBarItem
affects the StatusBar
layout. It seems like I can use HorizontalAlignment
on a StatusBarItem
, but not when I put the element in the S开发者_StackOverflow社区tatusBar
directly:
<StatusBar>
<TextBlock HorizontalAlignment="Right" Text="Not right" />
<StatusBarItem HorizontalAlignment="Center">
<TextBlock Text="Center" />
</StatusBarItem>
</StatusBar>
Also if you wrap a Separator
in a StatusBarItem
the Separator
changes to horizontal. Separator
s default to vertical when put in the StatusBar
directly without a StatusBarItem
wrapper.
A StatusBar
is an ItemsControl
. All ItemsControl
s have a container class. For ListBox
es, it's ListBoxItem
. For StatusBar
, it's StatusBarItem
. If you don't explicitly wrap your item in a StatusBarItem
, it will be implicitly wrapped in one for you.
If you need to set properties of an ItemsControl
's containers, you can use the ItemContainerStyle
property:
<StatusBar>
<TextBlock>One</TextBlock>
<TextBlock>Two</TextBlock>
<TextBlock>Three</TextBlock>
<StatusBar.ItemContainerStyle>
<Style TargetType="StatusBarItem">
<Setter Property="HorizontalAlignment" Value="Right"/>
</Style>
</StatusBar.ItemContainerStyle>
</StatusBar>
Finally, note that the StatusBar
uses a DockPanel
by default to lay out its children. This can be frustrating when you're doing intricate layouts. See my blog post here on how to swap it out for a Grid
.
