WPF/XAML - Scaling text size to window size

问题:

I'm new to WPF. I have a WPF Window with a bunch of Labels on it as well as a ListBox.

When resizing the window, I want to scale the size of SOME of the Labels, but not all of them. I don't want the ListBox to scale either--just some Labels.

I understand I can use a Viewbox to resize as the Window resizes, but as much as I mess with it, I'm not getting the desired effect. Of course I can't surround the entire thing with a Viewbox because that would resize everything, so I figured I would have to drop a bunch of different Viewboxes throughout the Window surrounding each label I want to expand. But of course... nothing expands at all when I do this.

Along the same lines, when I expand the labels, there are other labels that need to remain right next to those labels because they are identifiers.

So... here's the XAML I have at this point. I don't even know if I'm on the right path. Any help making the labels with number in them expand with the window would be appreciated.

You're on the right path. However, you need to use some column definitions, and your row definitions are a bit wonky. You're using a bunch of different layout panels embedded in each other, which is affecting the Viewbox built-in resizing. You can accomplish this exact same layout with a single, simple, 5x5 grid (no stackpanels).

I have demonstrated this in the following XAML:

<Window x:Class="TestWpfApplication.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:TestWpfApplication"
Title="Window1">
<Window.Resources>
    <Style TargetType="{x:Type Label}" x:Key="{x:Type Label}">
        <Setter Property="HorizontalAlignment" Value="Center"/>
        <Setter Property="VerticalAlignment" Value="Center"/>
    </Style>
</Window.Resources>

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition/>
        <RowDefinition/>
        <RowDefinition/>
        <RowDefinition/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>
        <ColumnDefinition/>
        <ColumnDefinition/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>

    <ListBox Grid.RowSpan="5" Grid.Column="0">
        <ListBoxItem>a</ListBoxItem>
        <ListBoxItem>b</ListBoxItem>
        <ListBoxItem>c</ListBoxItem>
    </ListBox>

    <Label Grid.Row="0" Grid.Column="1" Grid.ColumnSpan="4">Title</Label>

    <Label Grid.Row="1" Grid.Column="1">A</Label>
    <Label Grid.Row="2" Grid.Column="1">B</Label>
    <Label Grid.Row="3" Grid.Column="1">C</Label>
    <Label Grid.Row="4" Grid.Column="1">D</Label>

    <Viewbox Grid.Row="1" Grid.Column="2">
        <Label>1</Label>
    </Viewbox>
    <Viewbox Grid.Row="2" Grid.Column="2">
        <Label>2</Label>
    </Viewbox>
    <Viewbox Grid.Row="3" Grid.Column="2">
        <Label>3</Label>
    </Viewbox>
    <Viewbox Grid.Row="4" Grid.Column="2">
        <Label>4</Label>
    </Viewbox>

    <Viewbox Grid.Row="1" Grid.Column="3">
        <Label>5</Label>
    </Viewbox>
    <Viewbox Grid.Row="2" Grid.Column="3">
        <Label>6</Label>
    </Viewbox>
    <Viewbox Grid.Row="3" Grid.Column="3">
        <Label>7</Label>
    </Viewbox>
    <Viewbox Grid.Row="4" Grid.Column="3">
        <Label>8</Label>
    </Viewbox>

    <Label Grid.Row="1" Grid.Column="4">E</Label>
    <Label Grid.Row="2" Grid.Column="4">F</Label>
    <Label Grid.Row="3" Grid.Column="4">G</Label>
    <Label Grid.Row="4" Grid.Column="4">H</Label>
</Grid>
