UNSOLVED How to use GeUserArea.DrawCustomButton()

Hi,

I looked at the Python SDK and could not find a detailed explanation, so let me ask two questions about DrawCustomButton().

  1. What is the 5th argument "ids" for?

  2. Is there a way to receive a message or something when I click on the button?

Here is a simple script that opens a dialog with a UserArea and draws a button.
It looks like just a rectangle is drawn, but I wish I could create an interactive button that can receive triggers with InputEvent() or Message().

Thank you!

import c4d

class MyUserArea(c4d.gui.GeUserArea):
    def DrawMsg(self, x1, y1, x2, y2, msg_ref):
        # Initializes draw region
        self.OffScreenOn()
        self.SetClippingRegion(x1, y1, x2, y2)
        self.DrawRectangle(x1, y1, x2, y2)
        # Draws black background
        self.DrawSetPen(color=c4d.Vector(0))
        self.DrawRectangle(x1, y1, x2, y2)
        # Draws a button
        self.DrawCustomButton(x=20, y=20, w=80, h=40, ids=[0], nofill=False, focus=False)


class MyDialog(c4d.gui.GeDialog):
    ua = MyUserArea()
    def CreateLayout(self):
        area = self.AddUserArea(id=0, flags=c4d.BFH_SCALEFIT|c4d.BFV_SCALEFIT)
        self.AttachUserArea(ua=self.ua, id=area)
        return True

def main():
    dialog = MyDialog()
    dialog.Open(dlgtype=c4d.DLG_TYPE_MODAL, defaulth=200, defaultw=200)

if __name__ == '__main__':
    main()

Hi @ferdinand ,
I originally just asked out of curiosity, so no problem.
As for the topic, I would like to know the solution for when the time comes to use this gadget in the future.
Thank you.

Hi @kng_ito, I jsut checked with the original dev that implemented this function and this function should have been marked as private as Ids are not stable, so we will not communicate on them and we will fix documentation to reflect that this method is private.

With that's said I'm afraid , in any case it is not possible to automatically wire InputEvent, in a GeUserArea you have the drawing part and then it's up to you with pixel coordinate to know where the user clicked in InputEvent and then redraw your area accordingly.

Cheers,
Maxime.

Hi @m_adam ,
It is unfortunate because I thought it would be useful if it were available, but I understand.
Thank you for your prompt response!
