disable item in RC menu and in dropdownList menu

By artrender.info · 2013-05-05

Description

I have a RCmenu and It's working fine, but I don't know how to disable item in some circumstances


fn createMenu =
(
	rcMenu rcTest
	(
		menuItem miItem1 "name1"
		menuItem miItem2 "name2"
		menuItem miItem3 "name3"
		seperator menuSep01
		menuItem miItem4 "name4"
	)
        if a==0 then
           miItem1.enabled = false  --<<<<<< ??????????????????? >>>>>
        on miItem1 picked do  
	   print "1"
        ...

)

and a dropdownList menu where I want to disable items:


 dropdownList FilterSelect pos:[427,21] width:110 height:200
items:#("001", "002", "003", "004")
if a == 0 then item "002".enabled = false

it's my fault! I wanted to call delete item in another function but inside yours it's working!!

i've tried

artrender.info · 2013-05-13


deleteItem BitmapLister.FilterSelect.items[9]
and 
deleteItem BitmapLister.FilterSelect.items(finditem BitmapLister.FilterSelect.items "Map Intances")

and first gives error, the second does not delete!

when you use deleteItem method then you need:

deleteItem array index

I get error for deleteitem

>> MAXScript Rollout Handler Exception:
-- No "deleteItem" function for "Map Intances" <<

this is what I've came up with

artrender.info · 2013-05-06


try(form.close()) catch()
(
	global form = dotnetobject "MaxCustomControls.Maxform"
	form.ShowInTaskbar = form.MinimizeBox = form.MaximizeBox = off
	form.StartPosition = form.StartPosition.Manual
	form.Bounds = dotnetobject "System.Drawing.Rectangle" 800 200 100 60
 
	cm = dotNetObject "ContextMenu"
 
	fn onPopup s e = 
	(
		--fn onClick s e = undo "Delete" on deletemodifier s.parent.tag.value s.tag.value
		fn onClick s e = print "haha"
			
		for n in selection do
		(
			item = dotnetobject "MenuItem" n.name
			item.tag = dotnetmxsvalue n
			item.enabled = true--(n.modifiers.count > 0)
			s.menuitems.add item
			dotnet.addEventHandler item "Click" onClick
		)
	)
	fn onCollapse s e = s.menuitems.Clear()
 
	dotnet.addEventHandler cm "Popup" onPopup
	dotnet.addEventHandler cm "Collapse" onCollapse
 
	form.ContextMenu = cm	
	form.showmodeless()
)		
 
(
	delete objects 
	for k=1 to 8 do
	(
		n = #(box, sphere, cylinder, cone)[random 1 4] pos:(random -[50,50,50] [50,50,50]) wirecolor:(random red green)
		for i=1 to (random 0 5) do addmodifier n (#(UVWmap, Unwrap_UVW, Edit_Poly, Edit_Normals, XForm)[random 1 5]())  
	)
	redrawviews()
)

But how to use this menu in maxscript with rollout? How to add separator, how to detect which item was picked like in standard rcmenu?

Oh, yeeeeeeeeeeeeeees!!!

Help me please to disable items in RCMenu or to add them at a certain level (for example between item 2 and 3)

barigazy · 2013-05-05

I told you I not use RCMenu
Better way

fn defDDListItems ddlist choise: itm: =
(
ddlist.items = case choise of
(
(0): deleteItem ddlist.items (finditem ddlist.items itm)
(1): deleteItem ddlist.items (finditem ddlist.items itm)
(2):
(
local arr = ddlist.items
appendIfUnique arr itm ; sort arr
)
default:#("001", "002", "003", "004") -- if not used 0,1,2 or any other choise
)
)

dropdownList FilterSelect pos:[427,21] width:110 height:200 items:#("001", "002", "003", "004")

defDDListItems testroll.FilterSelect choise:0 itm:"002"
defDDListItems testroll.FilterSelect choise:1 itm:"004"
defDDListItems testroll.FilterSelect choise:2 itm:"006"
defDDListItems testroll.FilterSelect choise:#default itm:

In second example you can see how to disable items.
Select some yellow object and press rightclick on form

BUT

artrender.info · 2013-05-05

Is it possible to add items?

barigazy · 2013-05-05

I not like RCMenu but it's posible to disable a item. Never mind, let's continue with dd list

dropdownList FilterSelect pos:[427,21] width:110 height:200 items:#("001", "002", "003", "004")

testroll.FilterSelect.items = case a of
(
(0): deleteItem testroll.FilterSelect.items (finditem testroll.FilterSelect.items "002")
(1): deleteItem testroll.FilterSelect.items (finditem testroll.FilterSelect.items "004")
(2):
(
local arr = testroll.FilterSelect.items
appendIfUnique arr "005" ; sort arr
)
default:#("001", "002", "003", "004") -- if not used 0,1,2 or any other choise
)

ok!

I will try now!

Thx Barigazy! Again YOUUUUUUUUU save me!

artrender.info · 2013-05-05

do you mean to remove items? Will this work for rcmenu also?

barigazy · 2013-05-05

You can't disabled item in dropdown list. But you can do this

--load on creation
dropdownList FilterSelect pos:[427,21] width:110 height:200
itmArr = case a of
(
(0): #("001", "003", "004")
(1): #("001", "002", "003")
)
FilterSelect.items = itmArr

-- or remove affter creation
--Let's say your rollout name is testroll
dropdownList FilterSelect pos:[427,21] width:110 height:200 items:#("001", "002", "003", "004")
