Wpf window 显示对话框没有获得焦点

Question

I am calling a method using delegate to show a color window but that window not getting focus,It is working fine with mouse but for touch it requires one extra click to get focus.

 ColorPickerWindow colorPicker = new ColorPickerWindow ();
        colorPicker.Owner = this;
        colorPicker.ShowInTaskbar = false;
        colorPicker.SetColor(MenuColor);
        colorPicker.ShowDialog();

Answer 1

Just call Element.Focus() on the element you want to focus.

If you mean bring focus to the window try calling window.Activate()

Source: WPF Window set Focus

Answer 2

I found that window.ShowDialog() fails to get window focus (pops under) when .ShowDialog() is called on a thread other than the UI thread for your main window.

For me the problem went away when I made sure to .Invoke() my .ShowDialog() on the correct UI thread.
