状态栏中的WPF ProgressBar无法拉伸

本文关键字：ProgressBar WPF 状态栏 | 更新日期: 2023-09-27 18:10:37

新的WPF &我有以下XAML

<Window x:Class="Wpf.RossKiosk.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Topmost="True" WindowStartupLocation="CenterScreen" WindowState="Maximized" ResizeMode="NoResize" WindowStyle="None">
<DockPanel LastChildFill="True">
    <StatusBar Name="StatusBarMain" Height="30"  DockPanel.Dock="Bottom">
        <StatusBarItem HorizontalContentAlignment="Left">
            <TextBlock x:Name="TextBlockStatus" Margin="5,0,0,0" />
        </StatusBarItem>
        <StatusBarItem HorizontalContentAlignment="Stretch">
            <ProgressBar x:Name="ProgressBarMain" IsIndeterminate="True" Height="15" />
        </StatusBarItem>
        <StatusBarItem HorizontalContentAlignment="Right">
            <TextBlock x:Name="TextBlockInfo" Margin="5,0,0,0" TextAlignment="Right" />
        </StatusBarItem>
    </StatusBar>
    <Grid Name="GridMain">
        <!-- Dynamically Created buttons -->

    </Grid>

</DockPanel>

我想让进度条填充状态条的中心部分，但它只显示自己的宽度几个像素。什么好主意吗?

这是由于StatusBar在默认情况下使用DockPanel来布局其子节点。

您将需要使用Grid。DockPanel或StackPanel对你来说是不够的。试一试:

    <Grid>
    <StatusBar Name="StatusBarMain" Height="30" HorizontalAlignment="Stretch">
    <StatusBarItem HorizontalContentAlignment="Left">
        <TextBlock x:Name="TextBlockStatus" Margin="5,0,0,0" />
    </StatusBarItem>
    <StatusBarItem HorizontalContentAlignment="Stretch">
        <ProgressBar x:Name="ProgressBarMain" IsIndeterminate="True" Height="15" />
    </StatusBarItem>
    <StatusBarItem HorizontalContentAlignment="Right">
        <TextBlock x:Name="TextBlockInfo" Margin="5,0,0,0" TextAlignment="Right" />
    </StatusBarItem>
   </StatusBar>
    </Grid>

这对我很有帮助，但我需要添加网格行和列定义以使其正常工作。

<Grid VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Height="Auto" ToolTip="abc213">
          <Grid.RowDefinitions>
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="*"></RowDefinition>
        </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*"></ColumnDefinition>

这会将进度条延伸到它的容器

<StatusBarItem  Name="progressBarContainer">
    <ProgressBar Height="{Binding ElementName=progressBarContainer, Path=ActualHeight}" Width="{Binding ElementName=progressBarContainer, Path=ActualWidth}" Value="50" />
</StatusBarItem>
