Tool-palette Questions
« on: December 19, 2011, 09:19:00 pm »
1. I'm using the tool-palette function to make a menu. Most of the time when I go to open the menu on my calculator (it's always fine on the PC) it just doesn't open. Is this anything I can fix, or does it just work like that because it's an undocumented feature?
2. Is there any way to get a TI.image as an "icon" in the menu?
3. How likely is it that this feature will be taken out of the next firmware update?

ok i can answer at least one of your questions.
1. i tried it on onclua and after you register the menu you have to enable it.
if your menu structure is called "menu" and you have a menu called "Structures" then you have to se this function:
toolpalette.enable("menu", "Structures", true)
2. i dont think you can

Reo, the next firmware update shouldn't concern you unless it adds features or fixes deadly bugs (of which there are currently 0, deadly ones, that is). You can totally ignore them otherwise. The community's concern is accidental upgrades or new calcs coming with them.

Code: [Select]
function option1()
    --Write the commands here
end

function option2()
    --Write the commands here
end

menu = {
    {"Options Menu",
        {"option 1", option1},
        {"option 2", option2}
    }
}
 
toolpalette.register(menu)
this should work..

No, it isn't possible to but an image as icon.
You could however create your own menu system which supports that :)

You're all right about these questions.

Somethin I want to add, with Jimbauwens' remark is that Levak already implemented his own menu system withcomplete recursive-ness and image/icon support.

You can find some info here :
http://levak.free.fr/ftp/nspire/Make3D/Menu.lua

Here's the code directly :

Code: [Select]
-----------------------------

-----------------------------

------ Menu

Menu = class(Screen())

function Menu:init(items, convert)
if convert then -- the given format is a non-recursive toopalette, convert it
self.items = {}
local Btype2 = 1
for j, button in ipairs(items) do
local subitems, pic = {}, nil
if #button > 1 then
local Btype = 1
for i=2, #button do
if type(button[i]) == "table" then
table.insert(subitems, Button(0, 0, 0, 1.5, normal, button[i][2], button[i][1], button[i][3] or nullButton, nil, Btype))
if not pic and #button[i] > 2 then
pic = button[i][3]
end
if Btype < 3 then
Btype = 3
end
else
Btype = 1
end
end
subitems[#subitems].Btype = subitems[#subitems].Btype and subitems[#subitems].Btype == 1 and 0 or 2
end
self.items[j] = Button(0, 0, 0, 1.5, normal, function() end, button[1], pic or nullButton, Menu(subitems), Btype2)
Btype2 = 3
end
self.items[#self.items].Btype = 2

self.items = items
end

end

function Menu:format()
local i, xmax, ymax = 1, 0, 0

-- Get the maximum width
for _, button in ipairs(self.items) do
if type(button.text) ~= "string" or button.text == "" then
button.active = false
else
button.active = true

button.text = (i < 10 and tostring(i) or string.uchar(55 + i))..":"..button.text
if gc:getStringWidth(button.text) + button.h + 5 + 10 > xmax then
