TI is only locking it down because teachers want this, isn't it?
That and programs like OSlauncher and PTT Killer can be created.

yea, I will.
Also it seems to be with the third paramater of the gc:drawString function

not realy, some of the strings dont draw out in the same place as they used to. All I did was change on.create to on.construction in the "UseThisFile.lua" file I uploaded and I got rid of platform.gc() along time ago, but that is ok because it gives me a real good reason to go back and change the looks of some controls.

So after I found out that os 3.2 seems to draw things out diffrently than the os's < 3.2. Well I guess that the light at the end of the tunnel is that I can add some new stuff to the current controls.

It is, but he can use it as a reference once he learns more about how to program.

So here is a very very very basic type of menu. It has no sub-menus because I didnt have the time to do it today.
This should be written as a class, but since you probably dont know how to make classes, I didnt write it that way to make it less confusing.
menu = {{text = "small", selected = true, id = 1},
{text = "larger", selected = false, id = 2},
{text = "even larger", selected = false, id = 3},
{text = "sml", selected = false, id = 4}}--our menu
menuDrawn = false--menu flag
function on.paint(gc)
gc:setFont("serif", "r",7)
if menuDrawn then
--dynamicly find the width
local width = 0
local strHld = 0
for i = 1, table.maxn(menu) do
strHld = gc:getStringWidth(menu[i].text)
if strHld > width then
width = strHld + 1
end
end
strHld = gc:getStringHeight("Hh") --find the strings height
local height = strHld * table.maxn(menu)--find the total height
--fill grey rectangle
gc:setColorRGB(175, 175, 175)
gc:fillRect(0, 0, width, height)
--draw black rectangle
gc:setColorRGB(0, 0, 0)
gc:drawRect(0, 0, width, height)
--draw the strings
local y = 5
for i = 1, table.maxn(menu) do
if menu[i].selected then --reverse video
gc:fillRect(0, y - 6, width, strHld)
gc:setColorRGB(255, 255, 255)
gc:drawString(menu[i].text, 1, y, "middle")
gc:setColorRGB(0, 0, 0)
else
gc:drawString(menu[i].text, 1, y, "middle")
end
gc:drawLine(0, y + 7, width, y + 7)
y = y + strHld
end
end
end
function on.contextMenu() --pressed ctrl+menu
menuDrawn = not(menuDrawn)
end
function on.arrowUp() --up arrow was pressed
local fnd = findCurSelection()
if menu[fnd].id ~= 1 then
menu[fnd - 1].selected = true
else
menu[table.maxn(menu)].selected = true
end
menu[fnd].selected = false
platform.window:invalidate()
end
function on.arrowDown() --down arrow was pressed
local fnd = findCurSelection()
if menu[fnd].id ~= table.maxn(menu) then
menu[fnd + 1].selected = true
else
menu[1].selected = true
end
menu[fnd].selected = false
platform.window:invalidate()
end
function on.enterKey() --enter key was pressed
menu[findCurSelection()].text = "You pressed Enter"
platform.window:invalidate()
end
function findCurSelection() --find the current selected item
for i = 1, table.maxn(menu) do
if menu[i].selected then
return i
end
end
end
since this is a very basic outline, you could do alot with it.

I could probably make a very simple example and post it, also go to inspired-lua.org for the toolpallete question, even though it has been updated for 3.2, not alot has changed when it comes to creating the toolpallete

« on: June 08, 2012, 10:11:28 am »
do you mean like create, one of the toolpallete menus that are in the calculator app, or create your own from scratch?

« on: June 08, 2012, 10:08:17 am »
that would do it, i had just tried it and didnt get any errors

« on: June 08, 2012, 10:03:27 am »

312
« on: June 06, 2012, 10:07:15 pm »

313
« on: June 06, 2012, 04:28:14 pm »

also idk, everyone is saying something diffrent about when the os is comming out

True, but alot of critical stuff cant be written in C/C++. I may start with linux to get an idea about what I would be getting into, but later I would probably write one from scratch.
I probably wont try this though for a couple of years, so I know I have a very good understanding of C/C++ and asm.

That and I would like to write my own OS one day.
