GetObject with toggle option in menu

Scripting
1

Hi guys, I’m stuck here. Trying to create a custom getobject with a toggle option. The toggle option should be flipable forever until I select an object. When I select a single object I want to check in which state that toggle option is and depending on that call the function belonging to that option using the selected object.

After calling the function I want it to return back to the getobject menu with the toggle option.
This repeats until I press Enter or Esc to exit the command.

Anybody that can help out here? I’ve had a look this old topic but I couldn’t solve it based on that.

import Rhino

def Option1(obj):
    print "Do this to obj"
    GetObjectOption()

def Option2(obj):
    print "Do that to obj"
    GetObjectOption()

def GetObjectOption():
    go = Rhino.Input.Custom.GetObject()
    go.SetCommandPrompt("Select object")
    
    go.GeometryFilter = Rhino.DocObjects.ObjectType.Curve
    
    option = Rhino.Input.Custom.OptionToggle(True,"Option1","Option2")
    go.AddOptionToggle("Mode",option)
    
    go.Get()
    
    
    if I select an object while Option1 is activated:
        Option1(obj)
    
    elif I select an object while option2 is activated:
        Option2(obj)
    
    elif I press ESC or Enter:
        return

GetObjectOption()

I have something like this:

import Rhino
import rhinoscriptsyntax as rs
import scriptcontext as sc

def GetObjectPlusBoolean(prompt,b_opts,g_filt=None):
    go = Rhino.Input.Custom.GetObject()
    go.SetCommandPrompt(prompt)
    blnOption0=Rhino.Input.Custom.OptionToggle(b_opts[1],b_opts[2],b_opts[3])
    go.AddOptionToggle(b_opts[0],blnOption0)
    #allow preselected object
    go.EnablePreSelect(True,True)
    #main object type filter
    if g_filt: go.GeometryFilter=g_filt
    
    while True:
        get_rc = go.Get()
        if get_rc==Rhino.Input.GetResult.Cancel: return
        if get_rc==Rhino.Input.GetResult.Object:
            rhobj=go.Object(0)
            break
        elif get_rc==Rhino.Input.GetResult.Option:
            continue
    return (rhobj,blnOption0.CurrentValue)
    
def TestFunction():
    prompt="Select a surface or polysurface object"
    gf=Rhino.DocObjects.ObjectType.Brep
    a="OptionA" ; b="OptionB"
    bool_ini=["ChooseYourOption",True,b,a]
    result=GetObjectPlusBoolean(prompt,bool_ini,gf)
    if result is None:
        print "Function aborted"
    else:
        obj_Id=result[0].ObjectId
        msg="You chose object {} and {}".format(obj_Id,a if result[1] else b)
        print msg

TestFunction()

You can set go.EnablePreSelect(False,True) if you don’t want to accept a pre-selected object - which will short-circuit the option choice and take the default. I’ts also possible to set it up to remember the last used value via “sticky” but I didn’t do that here. You can also eliminate the geometry filter if you don’t care about the object type; or, you can also use a sub filter by setting up a go.SetCustomGeometryFilter() which I don’t have in the above example.

HTH, --Mitch

Thanks Mitch, I don’t have the time to look at it now but I think I can work from this.

Ok. I’m trying to dig through this and there’s quite some stuff that looks pretty advanced to me on first sight. But as I slowly go over each step I’m start to understand more and more. There’s some very nice tricks in there I didn’t know about, thanks!
