我进行了简单的尝试,似乎在设置无边框窗体的WindowState.Maximized
时忽略了Windows
Left
和Top
属性。
一个解决方法是忽略WindowState
函数并创建自己的Maximize
/Restore
函数。
下面是一个简单的示例。
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);
}
}
Xaml:
<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,您希望清理这段代码,但它似乎可以在任何任务栏
位置工作。但是,如果用户的字体DPI大于100%,则可能需要添加一些逻辑来获取正确的Left
,Top
。
