Re: [Iup-users] Problem with Executeleaf_cb Callback

I made some progress (figured out how to get the current node id) but I think I’m somehow calling the “leaffunc(t)” function wrong.

I adapted it from this old code that created a button for each module:

local dlg = {}

for cat in pairs(cats) do

for _,module in pairs(cats[cat]) do

local modbtnfunc = module.bindsettings

local modbtn = iup.button{title = module.label}

modbtn.action = "" modbtnfunc(t) end --"t" is the current profile table, which gets passed to module.bindsettings(profile)

table.insert(dlg, modbtn)

end

Those buttons worked fine, but when I tried to adapt it into a tree, I couldn’t figure out how to write the equivalent of the “modbtn” line.

The closest I can come is this:

for cat in pairs(cats) do

modtree.addbranch = cat --add a branch for each module category

for _,module in pairs(cats[cat]) do --iter thru each category and populate branches with modules

modtree.addleaf1 = module.label

local leaffunc = module.bindsettings

function modtree:executeleaf_cb(id)

iup.Message(id,modtree.title) -- this works and gives me the module name and the node id

leaffunc(t) --this doesn’t work and all leaves only open the same module

end

I tried a few ways of typing the function, but it didn’t work. How do I make it work like the button version?

I suggest you to store in each node some information that will allow you to retrieve the correct module and be able to show it.

Best,

I’m trying to populate a tree with the names of modules (leaves) so when you double-click on the name, the module dialog should pop up.
It almost works, but for some reason, every leaf opens the same module. How can I fix that?
This is the part of the code I have:

local modtree = iup.flattree{rastersize = "400x500"} --are there any more-flexible options than rastersize?
        modtree["addbranch-1"] = "MODULES" --add root node

        for cat in pairs(cats) do
                modtree.addbranch = cat --add a branch for each module category
                for _,module in pairs(cats[cat]) do --populate branches with modules
                       modtree.addleaf1 = module.label
                       function modtree:executeleaf_cb() module.bindsettings(t) end
                end
        end

Each module script starts with this code:

local module = {}
function module.bindsettings(profile)
…contains code about the dialog
