[Iup-users] Setting the caret position in MultiLine w/Lua?

[Antonio Scuri]

  Hi,

  The followinf code works just fine:

m = iup.multiline{size="200x200"}
b = iup.button{title="Go", action = function() m.caret = "10,10" end}
dg = iup.dialog{iup.vbox{m,b}}
dg:show() 

  Of course assuming that there are characters at line 10, column 10, so the
caret can be positioned.

  But inside the action it could be very confusing. Because the multiline
contents will be changed after the action callback, and I think that the
caret position will be also changed. So setting the caret inside the action
callback will be replaced by the new caret position.

Best,
scuri
