WPF实现抽屉菜单效果的示例代码
WPF 实现抽屉菜单
- 框架使用大于等于
.NET40； Visual Studio 2022;- 项目使用 MIT 开源许可协议；
- 更多效果可以通过GitHub[1]|码云[2]下载代码;
- 由于在WPF中没有现成的类似UWP的抽屉菜单，所以我们自己实现一个。
1） DrawerMenu.cs 代码如下。
using System.Collections.Generic;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;
namespace WPFDevelopers.Controls
{
public class DrawerMenu : ContentControl
{
public new static readonly DependencyProperty ContentProperty =
DependencyProperty.Register("Content", typeof(List<DrawerMenuItem>), typeof(DrawerMenu),
new FrameworkPropertyMetadata(null));
public static readonly DependencyProperty IsOpenProperty =
DependencyProperty.Register("IsOpen", typeof(bool), typeof(DrawerMenu), new PropertyMetadata(true));
public static readonly DependencyProperty MenuIconColorProperty =
DependencyProperty.Register("MenuIconColor", typeof(Brush), typeof(DrawerMenu),
new PropertyMetadata(Brushes.White));
public static readonly DependencyProperty SelectionIndicatorColorProperty =
DependencyProperty.Register("SelectionIndicatorColor", typeof(Brush), typeof(DrawerMenu),
new PropertyMetadata(DrawingContextHelper.Brush));
public static readonly DependencyProperty MenuItemForegroundProperty =
DependencyProperty.Register("MenuItemForeground", typeof(Brush), typeof(DrawerMenu),
new PropertyMetadata(Brushes.Transparent));
static DrawerMenu()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(DrawerMenu),
new FrameworkPropertyMetadata(typeof(DrawerMenu)));
}
public new List<DrawerMenuItem> Content
{
get => (List<DrawerMenuItem>)GetValue(ContentProperty);
set => SetValue(ContentProperty, value);
}
public bool IsOpen
{
get => (bool)GetValue(IsOpenProperty);
set => SetValue(IsOpenProperty, value);
}
public Brush MenuIconColor
{
get => (Brush)GetValue(MenuIconColorProperty);
set => SetValue(MenuIconColorProperty, value);
}
public Brush SelectionIndicatorColor
{
get => (Brush)GetValue(SelectionIndicatorColorProperty);
set => SetValue(SelectionIndicatorColorProperty, value);
}
public Brush MenuItemForeground
{
get => (Brush)GetValue(MenuItemForegroundProperty);
set => SetValue(MenuItemForegroundProperty, value);
}
public override void BeginInit()
{
Content = new List<DrawerMenuItem>();
base.BeginInit();
}
}
}
2） DrawerMenuItem.cs 代码如下。
using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;
using System.Windows.Media;
namespace WPFDevelopers.Controls
{
public class DrawerMenuItem : ListBoxItem
{
public static readonly DependencyProperty TextProperty =
DependencyProperty.Register("Text", typeof(string), typeof(DrawerMenuItem),
new PropertyMetadata(string.Empty));
public static readonly DependencyProperty IconProperty =
DependencyProperty.Register("Icon", typeof(ImageSource), typeof(DrawerMenuItem),
new PropertyMetadata(null));
public static readonly DependencyProperty SelectionIndicatorColorProperty =
DependencyProperty.Register("SelectionIndicatorColor", typeof(Brush), typeof(DrawerMenuItem),
new PropertyMetadata(DrawingContextHelper.Brush));
public static readonly DependencyProperty SelectionCommandProperty =
DependencyProperty.Register("SelectionCommand", typeof(ICommand), typeof(DrawerMenuItem),
new PropertyMetadata(null));
static DrawerMenuItem()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(DrawerMenuItem),
new FrameworkPropertyMetadata(typeof(DrawerMenuItem)));
}
public string Text
{
get => (string)GetValue(TextProperty);
set => SetValue(TextProperty, value);
}
public ImageSource Icon
{
get => (ImageSource)GetValue(IconProperty);
set => SetValue(IconProperty, value);
}
public Brush SelectionIndicatorColor
{
get => (Brush)GetValue(SelectionIndicatorColorProperty);
set => SetValue(SelectionIndicatorColorProperty, value);
}
public ICommand SelectionCommand
{
get => (ICommand)GetValue(SelectionCommandProperty);
set => SetValue(SelectionCommandProperty, value);
}
}
}
3） DrawerMenu.xaml 代码如下。
