我快速玩了一下,似乎在设置无边框表单时忽略了设置Windows
Left
andTop
属性。WindowState.Maximized
一种解决方法是忽略WindowState
函数并创建自己的Maximize
/Restore
函数
粗略的例子。
public partial class MainWindow : Window
{
private Rect _restoreLocation;
public MainWindow()
{
InitializeComponent();
}
private void MaximizeWindow()
{
_restoreLocation = new Rect { Width = Width, Height = Height, X = Left, Y = Top };
System.Windows.Forms.Screen currentScreen;
currentScreen = System.Windows.Forms.Screen.FromPoint(System.Windows.Forms.Cursor.Position);
Height = currentScreen.WorkingArea.Height;
Width = currentScreen.WorkingArea.Width;
Left = currentScreen.WorkingArea.X;
Top = currentScreen.WorkingArea.Y;
}
private void Restore()
{
Height = _restoreLocation.Height;
Width = _restoreLocation.Width;
Left = _restoreLocation.X;
Top = _restoreLocation.Y;
}
private void Button_Click_1(object sender, RoutedEventArgs e)
{
MaximizeWindow();
}
private void Button_Click_2(object sender, RoutedEventArgs e)
{
Restore();
}
protected override void OnMouseMove(MouseEventArgs e)
{
if (e.LeftButton == MouseButtonState.Pressed)
{
DragMove();
}
base.OnMouseMove(e);
}
}
xml:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="74.608" Width="171.708" ResizeMode="NoResize" WindowStyle="None">
<Grid>
<Button Content="Max" HorizontalAlignment="Left" Margin="0,29,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click_1"/>
<Button Content="Restore" HorizontalAlignment="Left" Margin="80,29,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click_2"/>
</Grid>
</Window>
显然你会想要清理这个代码,但它似乎在任何地方Taskbar
都可以工作,但是你可能需要添加一些逻辑来获得正确的Left
,Top
如果用户字体 DPI 大于 100%
