Hi,
I was trying to learn how to use the formatting capabilities of
iuptext and I modified the multiline.wlua example in the examples
directory. Here is what I did:
-- IupMultiline Simple Example in IupLua
-- Shows a multiline that ignores the treatment of the 'g' key, canceling
its effect.
require( "iuplua" )
ml = iup.text{MULTILINE = "YES", FORMATTING = "YES", expand="YES", value="I
ignore the 'g' key!", border="YES"}
tags = iup.user { bulk = "Yes", cleanout = "Yes" }
ml.action = function(self, c, after)
if c == iup.K_g then
iup.Append(tags, iup.user { selectionpos = "0:3", fgcolor = "255 0 0"})
print("removed formatting")
ml.addformattag = tags
print("added format tag")
return iup.IGNORE
elseif c == iup.K_b then
iup.Append(tags, iup.user { selectionpos = "4:7", fgcolor = "0 255 0"})
ml.addformattag = tags
return iup.DEFAULT;
else
return iup.DEFAULT;
end
end
dlg = iup.dialog{ml; title="IupMultiline", size="QUARTERxQUARTER"}
dlg:show()
if (iup.MainLoopLevel()==0) then
iup.MainLoop()
end
The 1st g press works fine and I get the foreground color then i press b
that although changes the next foreground color Lua crashes. It crashes
even if g is pressed the second time.
I am trying to dynamically change the formatting of the text in the
text box. What am I doing wrong?
Thanks,
Milind
