WPF:删除标题/控件框

Question

我刚从WinForms切换到wpf,在WinForms中删除整个标题框非常简单,只需设置title =""和ControlBox = false.

现在有很多关于如何使用wpf执行此操作的建议,所有这些都使用本机Win32调用.虽然它们确实移除了控制盒,但它们仍然在顶部留下较厚的边框.

这就是我想要的样子.

我确定使用某种原生呼叫是可行的,但是怎么样？

Answer 1

好吧,试试吧

WindowStyle="none"

像这样:

<Window x:Class="Test.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow"  WindowStyle="None"
    MinHeight="350" MaxHeight="350" MinWidth="525" MaxWidth="525">
<Grid>

</Grid>
</Window>

编辑:

它看起来有点愚蠢,但这种方式(Min-和MaxHeight/Width在相同的大小)你可以防止窗口调整大小

Answer 2

这是另一种方法.要删除Max- /最小化,您需要更改ResizeMode此类似的内容

<Window x:Class="MyWpfApplication.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="" Height="350" Width="525" ResizeMode="NoResize">
    <Grid>

    </Grid>
</Window>

之后你可以通过添加这个删除关闭按钮(在这里阅读更多)

private const int GWL_STYLE = -16;
private const int WS_SYSMENU = 0x80000;
[DllImport("user32.dll", SetLastError = true)]
private static extern int GetWindowLong(IntPtr hWnd, int nIndex);
[DllImport("user32.dll")]
private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);

public MainWindow()
{
    SourceInitialized += Window_SourceInitialized;
}

void Window_SourceInitialized(object sender, EventArgs e)
{
    var hwnd = new WindowInteropHelper(this).Handle;
    SetWindowLong(hwnd, GWL_STYLE, GetWindowLong(hwnd, GWL_STYLE) & ~WS_SYSMENU);
}
