Get CustomGUI Data in python

  • Hello plugincafe!
    I have recently created a customgui using the example customgui plugin. The only major thing that I changed, appart from drawing, is that I save a single float value.
    I now need to implement this custom gui into a python plugin but I can't seem to find out how to retrieve my saved data from the gui element.

    Do I need to completely switch to a c++ plugin to do this, or is there a way in python.

    Kind Regards,

  • Hi if your data type is already a know python type you shouldn't have any issue and could use the BaseCustomGui.GetData / BaseCustomGui.SetData.

    So if we take the C++ example of the String Custom GUI.
    You can use it in Python like bellow:

    import c4d
    ID_CUSTOM_GUI = 1001
    ID_BUTTON_DO = 1002
    class myCustomGuiDlg(c4d.gui.GeDialog):
        def CreateLayout(self):
            self._customGui = self.AddCustomGui(ID_CUSTOM_GUI, 1034655, 'my value', c4d.BFH_SCALEFIT, 50, 10)
            self.AddButton(ID_BUTTON_DO,c4d.BFH_SCALEFIT,name = 'Get Data')
            return True
        def InitValues(self):
            self._customGui.SetData("Some custom text")
            return True
        def Command(self, id, msg):
            if id == ID_BUTTON_DO:
                print self._customGui.GetData()
            return True
    if __name__=='__main__':
        dlg = myCustomGuiDlg()


  • Hello Maxime,
    thanks for you answer!
    I actually have my custom gui not in a GeDialog but inside a res file of an ObjectData. How would I be able to access the customgui from there?

    Best Regards,

  • In an ObjectData plugin, you don't access GUIs. You access parameters. So what is the parameter type that is using your custom GUI? Can you show your *.res file?

  • Hello Sebastian,
    basically I have something like this


    that is what I use.

  • Sorry, but this is not how it works. A NodeData's res file looks like this:


    The first symbol is the data type (STRING), the second the parameter ID, The custom GUI can be found after the CUSTOMGUI keyword.

    So in your case, MY_CUSTOMGUI is NOT a custom GUI. It is a custom data type. Is that correct?

  • oh... yeah that is true.

    I edited the customdata_customgui example to fit my needs. (mainly only the drawing).
    So I guess I would have to change my customdata to a REAL customgui?

  • Please make sure you understand the difference between a data type and a GUI. A data type stores data of some type. A GUI displays that data and allows interaction with that data in the UI. But it does not persistently store the data.

    So if you want to have a parameter in your object that stores a float value, just use a REAL parameter. You can display that parameter in the UI using a custom GUI element. See for example customgui_string.cpp.

    best wishes,

  • Hello Sebastian,
    I now understand what the difference is, thank you very much!
    With the customdata_customgui example file I actually made both a GUI and a custom DataType. So I only needed to change my resource file and modifiy my data code a bit!

    Best Regards,
