WindowsFormsHost is a control that hosts the windows form type in WPF. It has a high priority and can cover other types of controls on the same window. The secondary development control of TE is a WindowsFormsHost control.

In order to float the control on the WindowsFormsHost window and achieve the translucent effect, another window can pop up on the wpf window that hosts WindowsFormsHost, the size is the same as the lower window, and the position changes with the change of the lower window.

Specific implementation:

Suppose you have two windows for wpf: MainWindow and FloatWindow, where MainWindow is the window that hosts WindowsFormsHost and FloatWindow is the floating window above.

Initialize the floating window in the Loaded event of MainWindow, and change the size and position of the window. For more information, please see the following code:

_ floatWin = new FloatWindow (this)

_ floatWin.Owner = this

_ floatWin.ShowInTaskbar = false

_ floatWin.Show ()

_ floatWin.Left = this.Left

_ floatWin.Top = this.Top

_ floatWin.Width = this.Width

_ floatWin.Height = this.Height

Above, you can keep the size and position of the floating window consistent with the lower window, and then set the transparency of the floating window.

You also need to set the following two properties of the main window in the Xaml of the floating window:

AllowsTransparency= "True" Background= "Transparent"

After that, the floating window above can add controls at will, set the Opacity property of the control, and then the control can be translucent.
