I agree with this.  Pollock is great.

Is that really the issue?  I wonder how the layout stuff could be causing
such a speed problem.  Do you have any ideas?  Could you possibly donate
your layout stuff?

Fractional's inside Fractional's and the like is extremely slow.
TextEdit's with large amounts of text is extremely slow. Apart from
that, I've not noticed anything really slow in Pollock.

As for donating the WithStyle layout engine? No.

I'm sorry but what's a "layout engine" in this context anyway?

Cheers!

It's a UI builder that runs off XML and lays out the panes created
from the XML using CSS layout rules. That's essentially WithStyle at
its core.

Carl, I was under the impression that it did not take "large amounts" of  
text to slow down a text editor in Pollock. Maybe we could define what  
"large amounts" of text is.

I guess this will force people to write with less lines of code :) i.e.  
LibertyBasic users :)

Seriously, from the demo you gave to us at NYC Smalltalk it did not seem  
that it took what I would consider large amounts of text.

I think it's important that VisualWorks come with supported libraries
for writing various graphics file formats.  I found a post from Eliot
that PNG file writing was going to be included with VW 7.2, but I had to
find it on the web.  Since the PNG file writing code seems to work well
it might not be crucial to have GIF and BMP support, but least it should
be possible to write JPEG files also.

So I went and changed my implementation to use an OriginExtentFrame inside
of a FractionalFrame.  I figured I could just capture the resizing event and
change the extent of the OriginExtentFrame myself.  Unfortunately this
didn't speed anything up.

Any ideas?  Should I just avoid FractionalFrames altogether?

Travis asked me how I was using FractionalFrames, so I sent him the
following.

I'm just using the FractionalFrame and RelationalFrame classes unmodified.
I use a TabControl to hold multiple TextEdit controls.  Here is how I
initialize the TabControl and its frame.  RelationalFrame is a subclass of
FractionalFrame.

 tabs := TabControl new.
 frame := RelationalFrame new.
 frame
  topOffset: 3;
  leftOffset: 3;
  rightOffset: -3;
  bottomOffset: -24.
 tabs frame: frame.

Then each instance of TextEdit get initialized like this:

 editor := TextEdit new.
 frame := FractionalFrame fullyAttached.
 editor frame: frame.

The TextEdit controls get added to the TabControl like so:

 (self mainWindow paneAt: #tabs) addPage: form label: 'tab label'.

Pretty simple.
