How to create splitted dialog window

[mikeudin]

Hello guys!
I have to make command plugin dialog window like on this example. How to add two groups with possibility to change size of two separated zones by dragging divider. Thank you!

I will come back with a proper reply when the SDK Team is back from holiday.
Have a happy new year!
Cheers,
Maxime.

Hi @mikeudin sorry to not come back earlier I forget about it.

Since I see it's still open I'm wondering if you have more questions about it.
But in any case, here it's how it works.
So you have to make a group with the flag c4d.BFV_GRIDGROUP_ALLOW_WEIGHTS then each element (gadget) of this group will have a dynamic size and can be dragged.
Then you must define some default parameters (like how many columns the group has).
This is done through a BaseContainer.
Then GeDialog.GroupWeightsLoad will apply the data from the BaseContainer.

Then to retrieve the new values defined when the user resizes something you can use GeDialog.GroupWeightsSave from the Message method by reacting to BFM_WEIGHTS_CHANGED.

Find a complete GeDialog example bellow

class MyDialog(c4d.gui.GeDialog):

    GRP_SUB = 10000

    def __init__(self):
        # A BaseContainer that will store the information about weight information of the group.
        # This is stored in a class member variable, this way if the dialog is closed and re-open 
        # weight information will not be lost and restored as previously
        self.groupWeights = c4d.BaseContainer()
        
    def CreateLayout(self):
        """
        This method is called automatically when Cinema 4D Create the Layout (display) of the Dialog.
        """

        if self.GroupBegin(self.GRP_SUB, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 2, 0, "", c4d.BFV_GRIDGROUP_ALLOW_WEIGHTS):
    
            self.AddStaticText(1000, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 0, 0, "1", c4d.BORDER_THIN_IN)
            self.AddStaticText(1001, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 0, 0, "2", c4d.BORDER_THIN_IN)
    
            self.AddStaticText(1002, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 0, 0, "3", c4d.BORDER_THIN_IN)
            self.AddStaticText(1003, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 0, 0, "4", c4d.BORDER_THIN_IN)
    
            self.AddStaticText(1004, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 0, 0, "5", c4d.BORDER_THIN_IN)
            self.AddStaticText(1005, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 0, 0, "6", c4d.BORDER_THIN_IN)
    
            self.AddEditNumberArrows(1006, c4d.BFH_SCALEFIT)
