I need help urgently. Anyone know how I can print a table that comes from a "for" loop in a "MATHEDIT." If you could put a small example

You could put your data in a ClassPad matrix to emulate a datagrid. This is a modified version of CPLua 0.9E's UI Example 2 that puts the data from a 2d table in a matrix with ClassPad syntax and display it in the mathedit. Note that I wrote this from the top of my mind; you could maybe use simpler code for joining the data table:

require("ui", "string")
win = ui.window{ name="Test2", expand = true}
mth = ui.mathedit{ x=0, y=0, width=152, height=75}
win:add( mth )

-- This is your data
data = {}
data[0] = {"0",	  "Count", "Price"}
data[1] = {"Apple",  10,	  20	 }
data[2] = {"Banana", 30,	  40	 }

-- This is how you process your data
s = "["
for _,v in pairs(data) do
	s = s .. "["
	s1 = ""
	for _,c in pairs(v) do
		s1 = s1 .. "," .. tostring(c)
	end
	s = s .. string.sub(s1, 2) .. "]"
end
s = s .. "]"

mth:settext(s)
win:show(true)
ui.start()

MicroPro thank you very much this works very well

I was just glancing at that code.. It looks very similar to luaFX. Maybe we can port some of the less complicated CPLua programs to luaFX. Of course, not having a stylus on FX-9860 might cause some problems, but I think we could use a cursor controlled by the arrow keys to do that. The calculator would probably have to be held sideways also to simulate the ClassPad's portrait screen. But I think it might be possible.

[MicroPro]

Which part looks similar to luaFX?

Yes it's lua but the user interface functions (

win = ui.window{...}

,

mth = ui.mathedit{...}

as well as other ui elements) are exclusive to ClassPad because of its touch screen. However, the text and graphics functions used in games and real programs are designed decently (thanks Orwell!). Download CPLua and read its functions.txt file to see the functions.

The UI functions could be implemented using a cursor, no (Lua libraries)? And I could probably implement them into CalGUI.

[MicroPro]

I didn't say it's impossible to implement that on other calculators but since other calcs don't have native UI controls it would need more effort.

Since fx calculator aren't natively touch-enabled, if I wanted to develop for it, I would note something about User Experience: using a keypad-controlled cursor will make the program more user-friendly, but will slow down advanced people working with programs. Smart arrangement of menus and shortcut keys makes it easier to operate a program for people who are used to pressing keys fast, while the cursor could help beginners in mastering the program.

[flyingfisch]

Yeah you are right. One of the bug complaint with TI touchpads is that you have to use a cursor. I'll think about it.

I could port the program engines though.
