获取 ProgressBar 来填充 StatusBarItem [英] Get ProgressBar to fill StatusBarItem

问题描述

我有一个 StatusBar，我想在其中放置一个停靠在左侧的 TextBlock 和一个填充剩余宽度的 ProgressBar.在我使用 WPF ProgressBar 的所有其他体验中，它会填充给定的容器，但是在这种情况下，它根本不会自动调整大小，它只是显示为一个小圆圈.手动设置其高度和宽度可以正常工作，但我希望它可以缩放到 StatusBar 的剩余宽度.

I have a StatusBar that I'd like to house a TextBlock docked to the left and a ProgressBar filling the remaining width. In all my other experiences with the WPF ProgressBar, it will fill its given container, however in this situation it doesn't auto-size at all, it just appears as a tiny circle. Setting its height and width manually work fine, but I'd like it to scale to the remaining width of the StatusBar.

这是我的 StatusBar 的 XAML:

Here's my XAML for the StatusBar:

<StatusBar DockPanel.Dock="Bottom" Height="25">
    <StatusBarItem DockPanel.Dock="Left">
        <TextBlock x:Name="lblStatus"  Margin="5,0,0,0"/>
    </StatusBarItem>
    <StatusBarItem>
        <ProgressBar x:Name="pgbStatus" />
    </StatusBarItem>
</StatusBar>

推荐答案

您只需要一个额外的属性:StatusBarItem 上的 Horizo​​ntalContentAlignment="Stretch".因此:

You just need one extra attribute: HorizontalContentAlignment="Stretch" on the StatusBarItem. Thus:

<StatusBar DockPanel.Dock="Bottom" Height="25">
  <StatusBarItem DockPanel.Dock="Left">
    <TextBlock x:Name="lblStatus" Margin="5,0,0,0"/>
  </StatusBarItem>
  <StatusBarItem HorizontalContentAlignment="Stretch">  <!-- Note extra attribute -->
    <ProgressBar x:Name="pgbStatus" />
  </StatusBarItem>
</StatusBar>
