Hi all:
Just a heads up on the behaviour of the text widget:
Currently setting the contents of the text widget is done by setting the model value of the widget's model. This causes two steps to be triggered as Tcl commands: 1. Erase text widget to empty display 2. Set new text and display this text
Now, if one is reading file contents to be display to the widget by using consequtive calls to read-line and setting each line as the new text widget content only the last line will be displayed, of course. And if this happens to be an empty line then just nothing will appear on the text widget.
In case you want to dig in deeper on that subject, well, we're here...
