我正在使用动态资源词典来翻译我的 GUI 元素。字典在启动时加载,或者可以在运行时更改。效果很好!
现在我必须以编程方式添加一些 GUI 元素..但更改翻译后它们不会更新..
下面是我如何“翻译”XAML 中的 GUI 元素:
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:tests.Dialogs" x:Class="tests.Dialogs.Dlg_Main"
xmlns:Translator="clr-namespace:tests.Translation"
Title="{DynamicResource DLG_MAIN_TITLE}"
Height="356" Width="711"
/>
这是我添加到 ListBox 的 MenuItem 类:
public class MenuItem : FrameworkElement
{
public MenuItem (string resourceKey, ClickAction action)
{
Action=action;
this.SetResourceReference(ContentProperty, resourceKey);
}
public void DoAction ()
{
if (Action!=null)
{
Action();
}
}
public delegate void ClickAction ();
private ClickAction Action;
public Object Content
{
get { return (Object)GetValue(ContentProperty); }
set { SetValue(ContentProperty, value); }
}
// Using a DependencyProperty as the backing store for Name. This enables animation, styling, binding, etc...
public static readonly DependencyProperty ContentProperty=DependencyProperty.Register("Content", typeof(Object), typeof(MenuItem), new PropertyMetadata("leer?"));
}
这是 ListBox 的 XAML 样式:
<SolidColorBrush x:Key="ItemBrush" Color="Transparent" />
<SolidColorBrush x:Key="SelectedItemBrush" Color="Orange" />
<Style x:Key="RoundedItem" TargetType="ListBoxItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<Border Name="ItemBorder" BorderBrush="Transparent" BorderThickness="8,0,0,0" Margin="0" Padding="5" Background="{StaticResource ItemBrush}">
<StackPanel Orientation="Horizontal">
<TextBlock Margin="10,0,0,0" Text="{Binding Content.Content, RelativeSource={RelativeSource TemplatedParent}}" FontSize="18" FontWeight="Normal" VerticalAlignment="Center" />
</StackPanel>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
ListBox 在 XAML 中像这样使用:
<ListBox
x:Name="gui_listbox_menu"
ItemContainerStyle="{StaticResource RoundedItem}"
Background="Transparent"
SelectionChanged="gui_listbox_menu_SelectionChanged"
Margin="0,20,0,0"
ItemsSource="{Binding MenuItems, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:Dlg_Main}}}"
/>
启动后,MenuItems 有正确的翻译,所以参考有效?!但是如果我在运行时更改语言,只有 MenuItems 仍然显示旧语言!
如果我以编程方式添加一个 Button 并将其 ReferenceSource 设置为 DynamicResource 它的内容也会在运行时发生变化!
Button btn_test=new Button();
btn_test.Content="test";
btn_test.Width=100;
btn_test.Height=100;
gui_tab_settings_grid.Children.Add(btn_test);
btn_test.SetResourceReference(Button.ContentProperty, "DLG_MAIN_TITLE");
但是我的 MenuItems 在运行时不会改变??!
欢迎任何帮助!
