about script

why not use script in mygui . for example: tolua++

who could have add scrpit in mygui?

this is lua scrpit.

function sliderHandler(args)
CEGUI.System:getSingleton():getGUISheet():setAlpha(CEGUI.toSlider(CEGUI.toWindowEventArgs(args).window):getCurrentValue())
end


function panelSlideHandler(args)
local scroller = CEGUI.toScrollbar(CEGUI.toWindowEventArgs(args).window)
local demoWnd = CEGUI.WindowManager:getSingleton():getWindow("Demo8")

local relHeight = demoWnd:getHeight():asRelative(demoWnd:getParentPixelHeight())

scroller:setPosition(CEGUI.UVector2(CEGUI.UDim(0,0), CEGUI.UDim(scroller:getScrollPosition() / relHeight,0)))
demoWnd:setPosition(CEGUI.UVector2(CEGUI.UDim(0,0), CEGUI.UDim(-scroller:getScrollPosition(),0)))
end
function colourChangeHandler(args)
local winMgr = CEGUI.WindowManager:getSingleton()

local r = CEGUI.toScrollbar(winMgr:getWindow("Demo8/Window1/Controls/Red")):getScrollPosition()
local g = CEGUI.toScrollbar(winMgr:getWindow("Demo8/Window1/Controls/Green")):getScrollPosition()
local b = CEGUI.toScrollbar(winMgr:getWindow("Demo8/Window1/Controls/Blue")):getScrollPosition()
local col = CEGUI.colour:new_local(r, g, b, 1)
local crect = CEGUI.ColourRect(col)

winMgr:getWindow("Demo8/Window1/Controls/ColourSample"):setProperty("ImageColours", CEGUI.PropertyHelper:colourRectToString(crect))
end

function addItemHandler(args)
local winMgr = CEGUI.WindowManager:getSingleton()

local text = winMgr:getWindow("Demo8/Window1/Controls/Editbox"):getText()
local cols = CEGUI.PropertyHelper:stringToColourRect(winMgr:getWindow("Demo8/Window1/Controls/ColourSample"):getProperty("ImageColours"))

local newItem = CEGUI.createListboxTextItem(text, 0, nil, false, true)
newItem:setSelectionBrushImage("TaharezLook", "MultiListSelectionBrush")
newItem:setSelectionColours(cols)

CEGUI.toListbox(winMgr:getWindow("Demo8/Window1/Listbox")):addItem(newItem)
end


local guiSystem = CEGUI.System:getSingleton()
local schemeMgr = CEGUI.SchemeManager:getSingleton()
local winMgr = CEGUI.WindowManager:getSingleton()

-- load our demo8 scheme
schemeMgr:loadScheme("Demo8.scheme");
-- load our demo8 window layout
local root = winMgr:loadWindowLayout("Demo8.layout")
-- set the layout as the root
guiSystem:setGUISheet(root)
-- set default mouse cursor
guiSystem:setDefaultMouseCursor("TaharezLook", "MouseArrow")
-- set the Tooltip type
guiSystem:setDefaultTooltip("TaharezLook/Tooltip")

-- subscribe required events
winMgr:getWindow("Demo8/ViewScroll"):subscribeEvent("ScrollPosChanged", "panelSlideHandler")
winMgr:getWindow("Demo8/Window1/Controls/Blue"):subscribeEvent("ScrollPosChanged", "colourChangeHandler")
winMgr:getWindow("Demo8/Window1/Controls/Red"):subscribeEvent("ScrollPosChanged", "colourChangeHandler")
winMgr:getWindow("Demo8/Window1/Controls/Green"):subscribeEvent("ScrollPosChanged", "colourChangeHandler")
winMgr:getWindow("Demo8/Window1/Controls/Add"):subscribeEvent("Clicked", "addItemHandler")

I think, right now, its easy to bind required functions to your scripting language. I've already done that for some (not directly, but through my game's functions).

Check out Squirrel if you're not so inclined to Lua. I personally like it more.

i dont't know where did mygui register the CEGUI.toScrollbar lua script function ;
for example i can use tolua_function(tolua_S,"addElementWindow",tolua_CEGUI_CEGUI_FrameWindow_addElementWindow00);
to register "getScrollPosition" and use this function in lua script;
but i haven't found some this about CEGUI.toScrollbar in the source code of mygui

Heh, this is sample code from CeGUI and it is not from MyGUI
