StackPanel 中的 WPF RichTextBox + 按钮 =>真是一团糟? [英] A WPF RichTextBox + Button in a StackPanel => what a mess?

问题描述

此代码:

<StackPanel Orientation="Horizontal">
                <RichTextBox />
                <Button Content="Dialog" />  
            </StackPanel>

在 StackPanel 左侧某处显示按钮到 RichTextBox 上，为什么?

shows the button somewhere on the left side of the StackPanel ONTO the RichTextBox, WHY?

哦，我刚刚看到它的宽度问题.RTB 几乎没有宽度，按钮位于其右侧.

edit: Oh I just saw its a width problem. The RTB has nearly no width and the button is righthand of it.

似乎我遇到了这个错误:WPF RichTextBox 没有设置宽度

edit: seems I run into this bug: WPF RichTextBox with no width set

解决方案对我不起作用！

solution does not work for me!

推荐答案

最好使用 Grid 和 RTB 的 Horizo​​ntalAlignment(和 VerticalAlignment)属性.

You'd be better off using a Grid and the HorizontalAlignment (and VerticalAlignment) properties of the RTB.

<Grid HorizontalAlignment="Stretch"
      VerticalAlignment="Stretch">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="Auto" />
    </Grid.ColumnDefinitions>
    <RichTextBox HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
    <Button Grid.Column="1" 
            Content="Dialog" 
            HorizontalAlignment="Right" 
            VerticalAlignment="Bottom" />
</Grid>
