Hello,
I needed a not modal dialog so i could not use iupGetParam.
I made a function to be called as
NM = NotModal(function() iup.Update(cnv) end,
{
{"angle",0.0,iup.dial,{orientation="CIRCULAR"}}, --
name,default,creation,arguments
{"zcam",50,iup.val,{min=0,max=500}},
{"radspersecond",math.pi,iup.dial,{orientation="CIRCULAR"}},
{"fogDensity",0,iup.val,{min=0,max=0.005}}
})
and then use NM.fogDensity to know actual value.
Every time I used sliders CPU time got worse and did not go down when
stoping interaction.
This problem disappeared when I changed
function ctrl:valuechanged_cb()
labelval.title = self.value ;
this[name] = self.value;
fun(name,self.value)
end
for
function ctrl:mousemove_cb(val)
labelval.title = val ;
this[name] = val;
fun(name,val)
end
It seems that the relevant line is this[name] = self.value;
Here are both versions
--------------------good one
function NotModal(fun,telems)
local elems = {}
local this = {}
this.vars = {}
for i,elem in ipairs(telems) do
local name = elem[1]
local inival = elem[2]
local verb = elem[3]
local args = elem[4] or {}
local label = iup.label{title=name}
local labelval = iup.label{title=tostring(inival),size = "100x10"}
local ctrl = verb(args)
function ctrl:mousemove_cb(val)
labelval.title = val ;
this[name] = val;
fun(name,val)
end
ctrl.value = inival
this[name] = inival
this.vars[#this.vars + 1] = {name = name, ctrl = ctrl, inival = inival}
elems[i] = iup.hbox{label,ctrl,labelval}
end
local butreset = iup.button{title="Reset"}
function butreset:action()
for i,var in ipairs(this.vars) do
var.ctrl:mousemove_cb(var.inival)
end
end
elems[#elems + 1] = butreset
this.dialog = iup.dialog{iup.vbox(elems),topmost="YES"}
this.dialog:show()
return this
end
-------------problematic one
function NotModal(fun,telems)
local elems = {}
local this = {}
this.vars = {}
for i,elem in ipairs(telems) do
local name = elem[1]
local inival = elem[2]
local verb = elem[3]
local args = elem[4] or {}
local label = iup.label{title=name}
local labelval = iup.label{title=tostring(inival),size = "100x10"}
local ctrl = verb(args)
function ctrl:mousemove_cb(val)
labelval.title = val ;
this[name] = val;
fun(name,self.value)
end
ctrl.value = inival
this[name] = inival
this.vars[#this.vars + 1] = {name = name, ctrl = ctrl, inival = inival}
elems[i] = iup.hbox{label,ctrl,labelval}
end
local butreset = iup.button{title="Reset"}
function butreset:action()
for i,var in ipairs(this.vars) do
var.ctrl:mousemove_cb(var.inival)
end
end
elems[#elems + 1] = butreset
this.dialog = iup.dialog{iup.vbox(elems),topmost="YES"}
this.dialog:show()
return this
end
-----------------------
why is this happening? I wish iupVal:mousemove_cb() dont gets deprecated!!!
