是否可以在标题栏中显示没有图标的wpf窗口？ [英] Is it possible to display a wpf window without an icon in the title bar?

问题描述

众所周知，如果wpf窗口的图标未定义，则会显示默认图标。我想在标题栏中显示没有任何图标的窗口。我意识到我可以使用一个空白的图像，但这会导致标题栏中的文本被偏移到右边。

有谁知道一个完全的方法删除图标？

（我尝试搜索类似的问题，但找不到任何东西。）

解决方案

简单的，将这段代码添加到你的窗口中：

  [DllImport（user32.dll ）] 
 static extern uint GetWindowLong（IntPtr hWnd，int nIndex）; 
 
 [DllImport（user32.dll）] 
 static extern int SetWindowLong（IntPtr hWnd，int nIndex，uint dwNewLong）; 
 
 private const int GWL_STYLE = -16; 
 
 private const uint WS_SYSMENU = 0x80000; 
 
 protected override void OnSourceInitialized（EventArgs e）
 {
 IntPtr hwnd = new System.Windows.Interop.WindowInteropHelper（this）.Handle; 
 SetWindowLong（hwnd，GWL_STYLE，
 GetWindowLong（hwnd，GWL_STYLE）&（0xFFFFFFFF ^ WS_SYSMENU））; 
 
 base.OnSourceInitialized（e）; 
} 
  

As we all know, if the icon for a wpf window is undefined then the default icon is displayed. I want to display a window without any icon in the title bar. I realise that I could use a blank image, however this would cause the text in the title bar to be offset to the right.

Does anyone know of a way to completely remove the icon?

(I tried searching for a similar question but couldn't find anything.)

解决方案

Simple, add this code to your window:

[DllImport("user32.dll")]
static extern uint GetWindowLong(IntPtr hWnd, int nIndex);

[DllImport("user32.dll")]
static extern int SetWindowLong(IntPtr hWnd, int nIndex, uint dwNewLong);

private const int GWL_STYLE = -16;

private const uint WS_SYSMENU = 0x80000;

protected override void OnSourceInitialized(EventArgs e)
{
    IntPtr hwnd = new System.Windows.Interop.WindowInteropHelper(this).Handle;
    SetWindowLong(hwnd, GWL_STYLE,
        GetWindowLong(hwnd, GWL_STYLE) & (0xFFFFFFFF ^ WS_SYSMENU));

    base.OnSourceInitialized(e);
}
