Set TreeView values dynamically

Hi everyone,

I was having a bit of experimentation with the TreeView custom GUI, which btw is preety awesome, but having some difficulty in setting the values correctly to each column.

So will explain the ideas/problems that I have which hopefully someone will be able to help.

Process 1: You add the selected objects to a list, by pressing the "Add" button.

Process 2:  Each selected object and values populate the list, in the correct column.
Issue 2: When I create a list, can't distribute the values correctly to each column. As per the final result example above.

It may be related with some of the code below (taken from a good example by Maxime: https://plugincafe.maxon.net/topic/10654/14102_using-customgui-listview&KW=tree&PID=56287#56287)

I can see that only works for one value, but would like set the 3 values.

    
    
    class PickObjs(object) :
    
        objSel = ""
        _selected = False
    
        def __init__(self, objSel) :
    
            self.objSel = objSel
            print self.objSel <-- PRINTS CORRECTLY THE OBJECT AND VALUES!
    
        @property
        def IsSelected(self) :
            return self._selected
    
        def Select(self) :
            self._selected = True
    
        def Deselect(self) :
            self._selected = False
    
        def __repr__(self) :
            return str(self)
    
        def __str__(self) :
            return self.objSel <--- CAN ONLY RETURN A STRING AT THE TIME?

Process 3: When changing the ComboBox value, change the axis value in list for check marked objects.
Issue 3:  Need to have the values in the correct place and access it to make the change. Not sure how this would be done?

Hopefully this is comprehensive, but please let me know if don't know what I'm talking about .

Thank you in advance!

Hi Andre,

we expect the issue rather in your implementation of the TreeViewFunctions. Maybe you can show us some code of these?

Hi Andre,

terribly sorry, I need to ask for a bit more patience. I'll get back to you as soon as possible. Hopefully still this week.

Hi Andre,

I think, the main problem of your code is, that you are actually storing tuples in the tree content list, not "PickObjs" (as all the rest of your code assumes). This causes all kinds of problems all over the place. This you will need to either debug yourself or ask someone in our community for help.

This is also the reason, why you get the entire tuple shown in the first column.

GetName() delivers only the content of the LV_TREE column (basically the main column).
All LV_USER columns you need to draw yourself in DrawCell(). Which again doesn't work in your code, because the tuples stored in the list have no GetName() function. Also DrawCell() needs to draw only the LV_USER columns, no need to take care of TREE_OBJ in there.

One general advice:
Pay attention to any errors on the Console. These can usually get you already a long way.

I hope, this helps to get you started.

Hi Andreas,

Thank you immensely for your help!

I've managed to correct the code and make it do what I wanted, with your advice, but (apologies if I didn't understand) how can I access the the data for each "cell"? I will get the LV_TREE obj but not the LV_USER data.

I understand that the list is only appending the LV_TREE obj and not the other two, because it is returned by the function.
My question would be how to attach the other LV_USER values to the same list, so I can use it in a later stage?
If this is not possible, should I create a new list/baseContainer?

Thank you so much!

Hi Andre,

I'm not sure I understand your question. if I fail to answer your question, please don't hesitate to ask again.

You need to differentiate two things. One is your data (i.e. a linked list of objects or an array of your PickObjects) and the other is the display in the TreeView.

The tree doesn't care for your data, but instead you need to tell it, what to display in the LV_TREE column (via GetName()) and for all other columns (via DrawCell()). In either function you get the obj parameter, which from the tree point of view is just an opaque reference (it's not used inside by the tree), which provides you with the means to pick whatever needed from your data.

Or to answer your question "how can I access the the data for each cell?" more directly: You don't. The tree does not store any data, it just displays your data.

Similar in the other direction. For example on left click onto the Axis column, you want to have a popup with axis options. Well, you again get the obj reference in MouseDown(). Then you can for example use ShowPopupDialog() and with the result you'd update your data or the entities referred to by your data. Of course you could achieve similar by using the tree's context menu directly (CreateContextMenu()).

Unfortunately here's also a small limitation of the Python API. The C++ API has PopupEditText(), which would allow for overlay text editing, roughly as shown in your screenshot, but that's currently missing in the Python API.

Hi Andreas,

You did answer it and you also gave me some alternative and ideas to use.
Thank you so much! It makes more sense, now.
I'm still getting the grips with Python, but it seems that C++ is the way to go as well.

Appreciate your patience and help! 

Have a great day!

Andre
