Python Scripting-Help with GeDialog.AddComboBox add child option

s_bach

Hello and welcome to the PluginCafe,

please post your questions regarding the Cinema 4D APIs in the "Cinema 4D Development" category. Also, please use tags and the Q&A system. You find all that information in "Read Before Posting".

Is your question how to get the currently selected item of the combo box?

You can implement the "Command" function of your dialog to be informed when the selected value changed. This way you could rename the object when that happens.

Alternatively, you can access the selected element using a custom member function of the dialog. You can use the returned value to do what you want in the caller code.

Something like this:

class TestDialog(gui.GeDialog):
    
    def CreateLayout(self):

        self.AddComboBox(5000, c4d.BFH_LEFT, 100, 10, False)
        self.AddChild(5000, 0, "Child 0")
        self.AddChild(5000, 1, "Child 1")
        self.AddChild(5000, 2, "Child 2")

        return True

    def Command(self, id, msg):

        # print currently selected "child""
        if id == 5000:
            value = self.GetInt32(5000)
            print("got value: " + str(value))


        return c4d.gui.GeDialog.Command(self, id, msg) 
    
    # custom function
    def GetSelectedChild(self):
        return self.GetInt32(5000)

def main():
    dialog = TestDialog()
    
    dialog.Open(c4d.DLG_TYPE_MODAL_RESIZEABLE, 132456, -1 ,-1 ,400 ,400)
    
    value = dialog.GetSelectedChild()
    
    op.SetName(str(value))
    c4d.EventAdd()

best wishes,

Hi Sebastian! Thanks a lot for your reply!!!

and for clarifying me about posting and categories

I couldn't figure out at the end to add command and that all complete script works by example that you send me here.

Maybe I wasn't clear enough of what I trying to do and to get as the final result.

My goal is that I make preset with names e.g child 0-or final name "Bath" and when I run script and chose from dropping menu of combo box e.g name "Bath" or some other next selection child 2 or final name "Patio" by selection from item with ready name "Patio" script and code automatically rename new spline based on selection from combobox eg I draw new Spline> and when I select from combo box child's selection Patio command will automatically rename spline to Patio,if is that possible? Plugin cafe is simply awesome,and I am happy so happy to discover it.
Thanks a lot for your reply!

Best Wishes

Hello,

a GeDialog of a Python script must be a modal dialog. This means that while this dialog is opened, you can only interact with that dialog.

Therefore you can use your script to change the name of any previously created (active) object.

@s_bach Hello Sebastian!

The main issue is when I implement command and custom member function into the whole script how you suggest in to previously reply, nothing happening and the script wouldn't work.Or when I just copy your code example in to script manager nothing happening,I am using R17 if that can maybe be one of the reasons why script not work?

class TestDialog(gui.GeDialog):

def CreateLayout(self):

    self.AddComboBox(5000, c4d.BFH_LEFT, 100, 10, False)
    self.AddChild(5000, 0, "Child 0")
    self.AddChild(5000, 1, "Child 1")
    self.AddChild(5000, 2, "Child 2")

    return True

def Command(self, id, msg):

    # print currently selected "child""
    if id == 5000:
        value = self.GetInt32(5000)
        print("got value: " + str(value))


    return c4d.gui.GeDialog.Command(self, id, msg) 

# custom function
def GetSelectedChild(self):
    return self.GetInt32(5000)

def main():
dialog = TestDialog()

dialog.Open(c4d.DLG_TYPE_MODAL_RESIZEABLE, 132456, -1 ,-1 ,400 ,400)

value = dialog.GetSelectedChild()

op.SetName(str(value))
c4d.EventAdd()

Thank you for reply!

Hello,

you have to add

if __name__=='__main__':
    main()

as usual to execute the script.

best wishes,
Sebastian

Hello,

It is not working, and script isn't executable as I said in previously message,

thank you for your reply,

Regards

Working fine for me, once I correct all the indentations. I am not sure whether your script's indents are okay, since the code is broken up into several code-quotes, but in case it's not: the methods of the class need to be indented under the class definition.

I don't see anything that would work under R19 (my current test) but not under R17 (your version) so this is a bit of guesswork. What is the console saying when you try to execute the code?

You will need to add a line to close the dialog, too, and to transform the returned value into the proper string instead of the index number as string... maybe use a dictionary for value/string pairs.

import c4d
from c4d import gui

dropdown_values = {
                   0:"Child 0",
                   1:"Child 1",
                   2:"Child 2"
                  }

class TestDialog(gui.GeDialog):

    pass_value = 0

    def CreateLayout(self):

        self.AddComboBox(5000, c4d.BFH_LEFT, 100, 10, False)
        self.AddChild(5000, 0, dropdown_values.get(0))
        self.AddChild(5000, 1, dropdown_values.get(1))
        self.AddChild(5000, 2, dropdown_values.get(2))
        return True

    def Command(self, id, msg):
        # print currently selected "child""
        if id == 5000:
            value = self.GetInt32(5000)
            print("got index: " + str(value) + ", value: " + dropdown_values.get(value))
            self.pass_value = value
            self.Close()
        return c4d.gui.GeDialog.Command(self, id, msg) 

    # custom function
    def GetSelectedChild(self):
        return self.pass_value

def main():
    dialog = TestDialog()

    dialog.Open(c4d.DLG_TYPE_MODAL_RESIZEABLE, 132456, -1 ,-1 ,400 ,400)

    value = dialog.GetSelectedChild()
    print "Value after call: ", value
    op.SetName(dropdown_values.get(value))
    c4d.EventAdd()

if __name__=='__main__':
    main()
