Subject: [Iup-users] Bug with iupText, double newlines, and formatting.

 

Hello,

 

  I'd like to report a weird bug I'm having with the iupText widget, when
formatting is enabled, and the text has double end-of-lines. Here's an
example that demonstrates this problem:

 

text = iup.text { multiline = "Yes", formatting = "Yes", expand = "Yes",
value = "Line1\n\nLine2\n\nLine3\n\nLine4\n\nLine5\n\n" }

b = iup.button { title = "Test", action = function() text.value = text.value
end }

dlg = iup.dialog { size = "100x150", iup.vbox { text, iup.hbox { iup.fill{},
b, iup.fill{} } } }

dlg:show()

 

  Notice how the default value has two \n between each piece of text. If you
run this in LuaConsole, and press the button, you'd get the following
screens:

  Basically, every time we assign something to text.value, the first \n\n is
being transformed to a single \n. So if you have several of them in the
control, and you re-assign the same value over and over (through save'n'load
for example), you'd loose one \n\n couple.

 

  I haven't been able to track this one yet into the source, but I'll try
whenever I have the opportunity. I only tested this under windows, so I
don't know if it's a driver issue or a generic iup issue.

 

  Thanks,
