the mini window, I wanna make a button which "mouseover" will change button color and text color...
however, I only can change the button color but the word txt was disappear...any suggestion? Thanks.


Original:
WindowText (login, "f2", Char[Char_list]["name"] .. "(" ..  Char[Char_list]["id"] .. ")",
					space_w + 5, b_start + 4, space_w + b_width, b_start + b_height,
					ColourNameToRGB ("blue"), false)

Mouseover:
function mouseover (flags,hotspot_id)
	if hotspot_id == 1 then
		WindowText (login, "f2", Char[Char_list[hotspot_id]]["name"] .. "(" ..  Char[Char_list[hotspot_id]]["id"] .. ")",
					space_w + 5, b_start + 4, space_w + b_width, b_start + b_height,
					ColourNameToRGB ("red"), false)
		WindowText (login, "f2", "Lv: " .. "500",
					space_w + (b_width/3*2) + 5, b_start + 4, space_w + b_width, b_start + b_height,
					ColourNameToRGB ("red"), false)	
Redraw ()
end
CancelMouseover:

function cancelmouseover (flags,hotspot_id)
	if hotspot_id == 1 then
		WindowText (login, "f2", Char[Char_list[hotspot_id]]["name"] .. "(" ..  Char[Char_list[hotspot_id]]["id"] .. ")",
					space_w + 5, b_start + 4, space_w + b_width, b_start + b_height,
					ColourNameToRGB ("white"), false)
		WindowText (login, "f2", "Lv: " .. "500",
					space_w + (b_width/3*2) + 5, b_start + 4, space_w + b_width, b_start + b_height,
					ColourNameToRGB ("white"), false)			
		print(type(hotspot_id),hotspot_id)
	else
		print(type(hotspot_id),hotspot_id)
	end --if
	Repaint ()
end -- cancelmouseover

I don't see where you change the button colour.

Also, before pasting any code into the forum, you need to make sure you're escaping out the forum codes. Right now your code is all italicized because the forum saw [i]. MUSHclient can do this for you automatically by going to Edit->Convert Clipboard Forum Codes

ok sorry...make it simple.

I don't know my approach is correct or not.

1. Want to make a login miniwindow, which have many button, some words describe the Character info on the button
2. when mouseover the button, the color of button change, words color change too
3. click to execute cmds ( This simple)
4. when Cancelmouseover, the the color change back

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

The problem I meet, was when the mouseover, the color of button was change, but the word disappear, and while cancelmouseover, the color change back, but the word still not appear. that's my question, and the code are as below, thanks.
---------------------------------------------------------

require ("db_login")

local char = table.getn(Char_list)
local space_w = 40
local space_h = 15
local b_start = 40

local window_w = space_w * 2 + b_width
local window_h = b_start + (b_height + space_h) * char

function mouseover (flags, hotspot_id)
 print(hotspot_id)
end --function


I just add this code inside, I found the reason why the text why cannot redraw, but why the mouseup can callout the "hotspot_id" be the right id but mouseover and cancelmouseover only return "nil"?

Hotspot IDs are strings, not numbers, so this will never be true:


	if hotspot_id == 1 then

Tkl1129 Hong Kong #6
Oh, you had remind me...its work now


local x = tonumber("" .. hotspot_id)


the local var "x" become a number in "1"
The login miniwindow work now..thanks~

Or even:



local x = tonumber(hotspot_id)
