[英]Change ImageBrush Imagesource programmatically with conditions (WPF)
我得到了这样的XAML
<Window x:Class="Imagebind.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Background="#FF3F3B51">
<Window.Resources>
<Style x:Key="ButtonStyle1" TargetType="{x:Type Button}">
<Setter Property="FocusVisualStyle">
<Setter.Value>
<Style>
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="2" SnapsToDevicePixels="True" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Setter.Value>
</Setter>
<Setter Property="Background" Value="#FFDDDDDD"/>
<Setter Property="BorderBrush" Value="#FF707070"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Padding" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" SnapsToDevicePixels="True">
<Border.Background>
<ImageBrush ImageSource="Cancel.bmp"/>
</Border.Background>
<ContentPresenter x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentStringFormat="{TemplateBinding ContentStringFormat}" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsDefaulted" Value="True">
<Setter Property="BorderBrush" TargetName="border" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" TargetName="border">
<Setter.Value>
<ImageBrush ImageSource="Cancel (Mouseover).bmp"/>
</Setter.Value>
</Setter>
<Setter Property="BorderBrush" TargetName="border" Value="#FFDDDDDD">
</Setter>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Background" TargetName="border">
<Setter.Value>
<ImageBrush ImageSource="Cancel (Pressed).bmp"/>
</Setter.Value>
</Setter>
<Setter Property="BorderBrush" TargetName="border" Value="#FF2C628B"/>
</Trigger>
<Trigger Property="ToggleButton.IsChecked" Value="True">
<Setter Property="Background" TargetName="border" Value="#FFBCDDEE"/>
<Setter Property="BorderBrush" TargetName="border" Value="#FF245A83"/>
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Background" TargetName="border" Value="#FFF4F4F4"/>
<Setter Property="BorderBrush" TargetName="border" Value="#FFADB2B5"/>
<Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="#FF838383"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<Button Content="" HorizontalAlignment="Left" Margin="174,226,0,0" VerticalAlignment="Top" Width="161" Height="24" Style="{DynamicResource ButtonStyle1}"/>
以及这样的C#代码
using System.Windows;
namespace Imagebind
{
public partial class MainWindow : Window
{
private string language;
public MainWindow()
{
string language = "english";
InitializeComponent();
if (language == "english")
{
/* Here I need to change Imagesource of ImageBrush of 3 state buttons programmaticaly
For example this Cancel (Mouseover).bmp for Cancel(english) (Mouseover).bmp
*/
}
}
}
}
因此,我所希望的是,如果用户使用不同的语言,则界面中的所有图像都将使用我设置的语言。 所以我需要将所有状态下按钮的所有图像更改为c#代码中的new。
如果要本地化应用程序,则应考虑研究现有的库来帮助您,例如WPFLocalizationExtension 。
为了回答您的紧迫问题,您可以将所有图像定义为静态属性或应用程序中某处的资源,然后根据语言将它们分配给正确的值。 如果在应用程序运行时不需要支持更改语言,则静态属性将更易于设置。
只需定义如下属性:
internal static class Images
{
public static Uri CancelMouseOver { get; set; }
}
像这样设置它们:
Images.CancelMouseOver = new Uri("Cancel(english) (Mouseover).bmp", UriKind.Relative);
然后像这样使用它们:
<ImageBrush ImageSource="{x:Static local:Images.CancelMouseOver}"/>
