在WPF中,当用户单击Minimize
按钮时,我希望窗口状态仍为正常状态。单击时没有任何反应。但是我不想禁用Minimize
按钮,Minimize
按钮已启用并且可见,单击时什么都不做。
我该怎么办?

您可以在StateChanged事件上实现此目的。 在XAML中:
<Window x:Class="WpfApp.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
StateChanged="Window_StateChanged">
在代码中:
private void Window_StateChanged(object sender, EventArgs e)
{
if (this.WindowState == WindowState.Minimized)
this.WindowState = WindowState.Normal;
}

这是this answer的略微修改形式,由于不必要的调整大小,我将其视为不是重复的形式:
using System.Windows.Interop;
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
this.SourceInitialized += new EventHandler(OnSourceInitialized);
}
private void OnSourceInitialized(object sender, EventArgs e)
{
HwndSource source = (HwndSource)PresentationSource.FromVisual(this);
source.AddHook(new HwndSourceHook(HandleMessages));
}
private IntPtr HandleMessages(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
{
// 0x0112 == WM_SYSCOMMAND, 'Window' command message.
// 0xF020 == SC_MINIMIZE, command to minimize the window.
if (msg == 0x0112 && ((int)wParam & 0xFFF0) == 0xF020)
{
// Cancel the minimize.
handled = true;
}
return IntPtr.Zero;
}
}
