Hello,
Does someone know how to make a text window using widgets? I need make a
window (or something like it) in which I can put all sort of text, like in a
text editor but non-editable. I hope you've understood me.
Thanks.

You are right, there�s no problem with it. But I wanted to put more than one
line.
The solution is very easy, using the /APPEND keyword, as someone wrote me:
Widget_Control, textID, Set_Value='Add to the text', /APPEND
So, this is the end of the problem.

I guess I'm not following you at all. That stuff is text isn't it?
Or, at the very least, is can be *made* into text. Why are you
having trouble putting it in a text widget?
dimensions = Size(image, /Dimensions)
newText = 'My Image -- Dimensions: [' + StrTrim(dimensions,2) + ']'
Widget_Control, textID, Set_Value=newText
Cheers,
David
