如何继承WPF样式按钮的行为？ [英] How to inherit Button behaviour in WPF style?
本文介绍了如何继承WPF样式按钮的行为？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经重写了WPF默认的最大化，最小化按钮的解释的此处。但是，在我的情况，而不是使用图片覆盖背景图像的按钮，我想补充我自己的模板。
I have overriden the WPF default Maximize, Minimize buttons like explained here. But, in my case, instead of using an Image to override background image for that buttons, I wanted to add my own template.
所以，我创建了一个的ResourceDictionary 适用风格的最大化/最小化/恢复/关闭按钮。
So I created a ResourceDictionary that applies a style for Maximize/Minimize/Restore/Close buttons.
的事情是，我重写的模板。作为一个例子，看到 PART_MINIMIZE 按钮：
The thing is that I override the template. As an example, see the PART_MINIMIZE button:
<Button x:Name="PART_MINIMIZE"
Width="30"
Height="20"
Margin="0,0,4,0"
HorizontalAlignment="Center"
Template="{DynamicResource MinimizeButton}"
VerticalAlignment="Center"
DockPanel.Dock="Right">
</Button>
在 DynamicResource 名为 MinimizeButton stablishes完整的模板。问题来了，当我按一下按钮。正如我重写模板部分，它有没有被我定义默认行为。但是，我想保持最大化/最小化/默认还原/关闭行为，而不覆盖它。所以......
The DynamicResource called MinimizeButton stablishes the full template. The problem comes when I click the button. As I override the Template part, it has no behaviour defined by me by default. But I want to keep Maximize/Minimize/Restore/Close behaviour by default, without overriding it. So...
我怎么能说继承了按钮的行为的模板？或者如何模拟呢？
How can I say in the template to inherit the behaviour of the button? Or how to simulate them?
谢谢！
推荐答案
操作与窗口应放置在一个特殊的类，将可从XAML，像
Operation with the Window should be placed in a special class that would be available from XAML, like that:
工作关闭：
<Trigger Property="IsChecked" Value="True">
<Setter Property="Controls:WindowBehaviours.Close" Value="True" />
</Trigger>
工作隐藏：
<Trigger Property="IsChecked" Value="True">
<Setter Property="Controls:WindowBehaviours.Hide" Value="True" />
</Trigger>
本使用切换按钮，因为他有属性器isChecked 通过触发访问。这些特性 - 连接的不同性质
This uses ToggleButton because he has property IsChecked accessible via a trigger. These properties - attached depending properties.
WindowBehaviours上市类：
public static class WindowBehaviours
{
// Close the Window
public static void SetClose(DependencyObject target, bool value)
{
target.SetValue(CloseProperty, value);
}
public static readonly DependencyProperty CloseProperty =
DependencyProperty.RegisterAttached("Close",
typeof(bool),
typeof(WindowBehaviours),
new UIPropertyMetadata(false, OnClose));
private static void OnClose(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
if (e.NewValue is bool && ((bool)e.NewValue))
{
Window window = GetWindow(sender);
if (window != null)
{
window.Close();
}
}
}
// Hide the Window
public static void SetHide(DependencyObject target, bool value)
{
target.SetValue(HideProperty, value);
}
public static readonly DependencyProperty HideProperty =
DependencyProperty.RegisterAttached("Hide",
typeof(bool),
typeof(WindowBehaviours),
new UIPropertyMetadata(false, OnHide));
private static void OnHide(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
if (e.NewValue is bool && ((bool)e.NewValue))
{
Window window = GetWindow(sender);
if (window != null)
{
window.WindowState = WindowState.Minimized;
}
}
}
// Full the Window
public static void SetFull(DependencyObject target, bool value)
{
target.SetValue(FullProperty, value);
}
public static readonly DependencyProperty FullProperty =
DependencyProperty.RegisterAttached("Full",
typeof(bool),
typeof(WindowBehaviours),
new UIPropertyMetadata(false, OnFull));
private static void OnFull(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
if (e.NewValue is bool && ((bool)e.NewValue))
{
Window window = GetWindow(sender);
if (window != null)
{
window.WindowState = WindowState.Maximized;
}
}
}
// Set the Window in Normal
public static void SetNormal(DependencyObject target, bool value)
{
target.SetValue(NormalProperty, value);
}
public static readonly DependencyProperty NormalProperty =
DependencyProperty.RegisterAttached("Normal",
typeof(bool),
typeof(WindowBehaviours),
new UIPropertyMetadata(false, OnNormal));
private static void OnNormal(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
if (e.NewValue is bool && ((bool)e.NewValue))
{
Window window = GetWindow(sender);
if (window != null)
{
window.WindowState = WindowState.Normal;
}
}
}
// Get the Window
private static Window GetWindow(DependencyObject sender)
{
Window window = null;
if (sender is Window)
{
window = (Window)sender;
}
if (window == null)
{
window = Window.GetWindow(sender);
}
return window;
}
}
使用的ToggleButtons 与 WindowBehaviours 类样品：
CloseButton
<Style x:Key="ToggleButtonWindowClose" TargetType="{x:Type ToggleButton}">
<Setter Property="Background" Value="Transparent" />
<Setter Property="SnapsToDevicePixels" Value="True" />
