【中文标题】在WPF中,当在无边框窗口中拖动自定义的标题栏时,窗口会恢复,如何实现呢?【英文标题】:In WPF, when drag the customized titlebar in the no-border window, the window will be restored, how to implement it? 【发布时间】:2013-09-22 14:51:30 【问题描述】:我已经定制了一个无边框窗口,它是no style
和no border
和AllowsTransparency="True"
,在这个窗口的顶部有一个矩形功能,而不是内置的标题栏。
一般情况下,拖动最大化窗口的标题栏即可恢复窗口,但在我自定义的无边框窗口中,我不知道如何实现。谁能帮帮我?
这是简单的代码:
<Window x:Class="WpfApplication24.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"
WindowStyle="None"
AllowsTransparency="True">
<DockPanel LastChildFill="False">
<Rectangle DockPanel.Dock="Top" x:Name="DragRectangle" Height="30" Fill="#FF123456" MouseLeftButtonDown="DragRectangle_MouseLeftButtonDown"/>
<Button x:Name="ToMaxButton" Content="ToMaxButton" Click="ToMaxButton_Click" Height="30" Margin="5"/>
<Button x:Name="ToNormalButton" Content="ToNormalButton" Click="ToNormalButton_Click" Height="30" Margin="5"/>
<Button x:Name="CloseButton" Content="CloseButton" Click="CloseButton_Click" Height="30" Margin="5"/>
</DockPanel>
</Window>
和
namespace WpfApplication24
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
public MainWindow()
InitializeComponent();
private void DragRectangle_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
this.DragMove();
private void ToMaxButton_Click(object sender, RoutedEventArgs e)
this.WindowState = System.Windows.WindowState.Maximized;
private void CloseButton_Click(object sender, RoutedEventArgs e)
this.Close();
private void ToNormalButton_Click(object sender, RoutedEventArgs e)
this.WindowState = System.Windows.WindowState.Normal;
已编辑:
通过拖动原来的Window,我们会发现我们需要拖动一点距离然后改变window.state,那么窗口的位置就会和光标的坐标差不多了。
【问题讨论】:
【参考方案1】:您可以添加 MouseUp 和 MouseMove 处理程序
private bool _isMouseDown = false;
private void DragRectangle_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
_isMouseDown = true;
this.DragMove();
private void DragRectangle_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
_isMouseDown = false;
private void DragRectangle_MouseMove(object sender, MouseEventArgs e)
// if we are dragging and Maximized, retore window
if (_isMouseDown && this.WindowState == System.Windows.WindowState.Maximized)
_isMouseDown = false;
this.WindowState = System.Windows.WindowState.Normal;
【讨论】:
请参阅编辑。如果简单地设置_isMouseDown
和WindowState
,位置将被恢复,而不是保持光标位置几乎相同。现在,我正在阅读“archive.msdn.microsoft.com/WPFShell”,也许它会给我一些启发。以上是关于在WPF中,当在无边框窗口中拖动自定义的标题栏时,窗口会恢复,如何实现呢?的主要内容,如果未能解决你的问题,请参考以下文章
