Scripting the path in Quick Selection Tool

Question

Hi,
I'm trying to build a JS script which:
1. opens an image
2. selects the quick selection tool
3. does the selection following a pre-defined path
4. puts the unselected area to white
5. saves the image
The problem is in step 3. All the other steps can be recorded with ScriptListener, but the path is not. So the question is:
How can I tell to my script a path to follow while using Quick Selection?
How can I do it, for example, with a very simple path, say a line from pixel (50,50) to (50,200)?
Many thanks!

Answer 1

This would select the first path and stroke it with the Quick Selection Tool, for the second part it uses the Action Manager recorded with ScriptingListener.plugin.
app.activeDocument.pathItems[0].select();

    var idquickSelectTool = stringIDToTypeID( "quickSelectTool" );
    desc7.putClass( idUsng, idquickSelectTool );
    var idPrs = charIDToTypeID( "Prs " );
    desc7.putBoolean( idPrs, true );
executeAction( idStrk, desc7, DialogModes.NO );
