Returns the mouse's position in this [CanvasItem] using the local coordinate system of this [CanvasItem].

<method name="get_screen_transform" qualifiers="const">
<return type="Transform2D" />
<description>
Returns the transform of this [CanvasItem] in global screen coordinates (i.e. taking window position into account). Mostly useful for editor plugins.
Equals to [method get_global_transform] if the window is embedded (see [member Viewport.gui_embed_subwindows]).

<description>
Returns the position of this [Control] in global screen coordinates (i.e. taking window position into account). Mostly useful for editor plugins.
Equals to [member global_position] if the window is embedded (see [member Viewport.gui_embed_subwindows]).
Example usage for showing a popup:
[codeblock]
popup_menu.position = get_screen_position() + get_local_mouse_position()
popup_menu.reset_size()
popup_menu.popup()
[/codeblock]

If [code]true[/code], sub-windows (popups and dialogs) will be embedded inside application window as control-like nodes. If [code]false[/code], they will appear as separate windows handled by the operating system.
