I found a strange undo behavior in max 2011. In max 2010 this works just fine.
This is the problematic code:
try(destroydialog testR)catch()
rollout testR ""
(
local listItems = #("Translate X","Translate Y","Translate Z","Rotate X","Ratate Y","Rotate Z","Scale X","Scale Y","Scale Z")
dotNetControl attribListLV "System.Windows.Forms.Listbox" height:170 width:96 pos:[2,20]
fn initAttribListLV = (
attribListLV.items.addrange ListItems
)
on attribListLV MouseDown _button do
(
if _button.button==_button.button.right do
(
print "Undo"
max undo
)
)
on testR open do
(
initAttribListLV()
)
)
createdialog testR pos:[200,200]
But when I evaluate “max undo” as the button event, it works:
try(destroydialog testR2)catch()
rollout testR2 ""
(
button testB "Press Me"
on testB pressed do(
print "Undo"
max undo
)
)
createdialog testR2
This looks like bug to me. But maybe there is a workaround of this?
if _button.button==_button.button.right do…
it’s probably never TRUE
if _button.button==_button.button.right
It is true when user right click on the Listbox, but even if we use this instead:
on attribListLV MouseDown _button do
(
print "Undo"
max undo
)
It still does nothing with undo.
Do you want to say that a Listbox control doesn’t fire MouseDown event in MAX 2011?
It fires everything exept ‘undo max’.
I put the print command before and after undo to be sure that max read this command. It looks like max only cann’t run ‘max undo’ from dotNet listbox.
strange… i have no idea how it might be possible. Does it do Undo on MouseUp or MouseClick events?
Yes MouseUp works, but also only without any mouse button check. Others events doesn’t work.
