- Actually, from having just looked at the viola code, I don't see that it
- uses a text widget anywhere. They have their own code to figure out the
- visible text, and draw it each time.

- How many X text widgets are you aware of? Certainly the Motif Text widget
- does NOT do what you describe. The Athena Text widget does. You have some
- other text widget somewhere you are referring to?
-
-
- As the author of the HTMLwidget (yes, it IS a widget, and you could link it
- into either Athena or Motif and it will work with the other widgets) I
- suppose I should defend it a little here.
-
- In general the criticisms of my design decision are correct, in specifics
- they have all been wrong. As I believe others have pointed out by now, your
- X server is NOT allocating some huge chunk of memory. Motif made the same
- decision I did, and Athena did not. There are many reasons behind the
- decision, I will only mention one important one here that no one else has
- covered yet. I wanted my widget to work with other widgets sets
- (specifically with either Athena or Motif). In order to do the kind of
- viewport scrolling Bill would like, the widget, has to know intimate details
- about the internals of a second scrollbar widget which it is going to
- display for scrolling. This ties you to whatever widgets set's scrollbar
- you end up using.
-
- In the long run (xmosaic 2.0 or 3.0 if the project lasts that long) the
- widget will be changed to do pretty much what Bill describes. This will
- tie it to the Motif widget set, and make it unusable in other widget
- sets. I personally dislike this because I disapprove of OSF's frequently
- heavy handed methods, and don't like to see all my work benefitting them,
- and only them, but other design decisions override my personal preferences,
- and simple practicality forces the widget re-write.
-
-
- As to the heated argument that seems to have resulted. Sigh........
- It would be nice if everyone double checked their facts before posting
- them to thousands of people world-wide, but the majority of the people
- on the net do not (including me at times). This is unfortunate.
-
- Marc,
- It seems to be human nature that if something works and they like
- it, most say nothing. But if they don't like it, most yell loudly.
- Someone once told me you can tell a software success by how many people
- were complaining, the more complaints, the more successful it was. I
- believe this is true. So far we are in the envious position of receiveing
- MORE praise than complaints. Think a moment about how many happy quiet
- people this means, compared to how few unhappy noisy people
