@m_adam thank you for your answer from the code, it similar to what i already try, but this way looks like not a perfect solution. actually after read most c4d gui sdk and write some examples, i think maybe c4d should update gui model? sometimes it not flexible. just my personal thoughts, don't mind : ) expect python 3.x and pyside2 coming : )

hi,
i write a GUI and use mouse left to refresh GeUserarea , mouse right stop refresh. Unfortunately, when click mouser left, it crash. Somebody can tell me what I did wrong ？ this is my code.
Hope your help!

import c4d
from c4d import gui

class MyArea(gui.GeUserArea):
    def __init__(self) :
        self.leftclick = False

    def GetMinSize(self) :
        return (600, 500)

    def DrawMsg(self,x1, y1, x2, y2, msg):
        self.DrawSetPen(  c4d.Vector(.21) )
        self.DrawRectangle(x1, y1, x2, y2)

    def Message(self, msg, result):
        if msg.GetId():
            if self.leftclick:
                self.Redraw()
        return c4d.gui.GeUserArea.Message(self, msg, result)
    
    def InputEvent(self, msg) :
        if msg[c4d.BFM_INPUT_DEVICE] == c4d.BFM_INPUT_MOUSE:
            if msg[c4d.BFM_INPUT_CHANNEL] == c4d.BFM_INPUT_MOUSELEFT:
                self.leftclick = True
            if msg[c4d.BFM_INPUT_CHANNEL] == c4d.BFM_INPUT_MOUSERIGHT:
                self.leftclick = False
        return True

class Dialog(gui.GeDialog):
    def __init__(self, area) :
        self.area = area

    def CreateLayout(self) :
        self.AddUserArea(10010, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT)
        self.AttachUserArea(self.area, 10010)
        return True

def main():
    area = MyArea()
    MyDialog = Dialog(area)

    MyDialog.Open(c4d.DLG_TYPE_MODAL_RESIZEABLE)

if __name__ == "__main__":
    main()
