我有一个包含一些非斜体文本的文本块。当鼠标进入文本块时,文本会通过使用后面的代码进行更改。我希望后面的代码也能够将文本更改为斜体。这就是我到目前为止所做的:
XAML:
<TextBlock x:Name="block1"
Background="Cyan"
Foreground="{StaticResource myBrush2}"
Grid.Column="0"
Grid.Row="0"
Height="30"
HorizontalAlignment="Center"
MouseEnter="TextBlock_MouseEnter"
MouseLeave="TextBlock_MouseLeave"
Padding="0,7,0,0"
Text ="Hover Me!"
TextAlignment="Center"
Width="100"/>
背后的代码(C#):
public void TextBlock_MouseEnter(object sender, MouseEventArgs e)
{
string blockName = ((TextBlock)sender).Name;
var block = sender as TextBlock;
if (block != null && blockName == "block1")
{
block.Text = "Yo! I'm TextBlock1";
}
}
我已经研究过使用System.Drawing和使用FontStyle.Italic;虽然我没有成功实际工作。

这是XAML
为
<TextBlock x:Name="block1"
Background="Cyan"
Foreground="{StaticResource myBrush2}"
Grid.Column="0"
Grid.Row="0"
Height="30"
HorizontalAlignment="Center"
MouseEnter="TextBlock_MouseEnter"
MouseLeave="TextBlock_MouseLeave"
Padding="0,7,0,0"
Text ="Hover Me!"
TextAlignment="Center"
Width="100">
<TextBlock.Style>
<Style TargetType="TextBlock">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="FontStyle" Value="Italic" />
</Trigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>
但是,如果你真的想要,这里有一个如何从代码隐藏中实现该功能的例子。
private void block1_MouseEnter(object sender, MouseEventArgs e)
{
SetFontStyle(FontStyles.Italic);
}
private void block1_MouseLeave(object sender, MouseEventArgs e)
{
SetFontStyle(FontStyles.Normal);
}
private void SetFontStyle(FontStyle style)
{
block1.FontStyle = style;
}
