[jaxx-interest] new blog entry: "Reinventing GridBagLayout"

[Anderson, Kelly]

ok, that sounds like what I call a grid. It is also very useful. I'm
glad to hear that you have VBox and HBox.

Do the individual widgets have a minimum, maximum and desired size? How
is the layout computed? Proportional to the maximum size of the widgets?
Or some other mechanism? 

One of the things our geometry model had was top down resizing (that is,
the user resizes the dialog) and bottom up resizing (that is, a widget
asks to have more space). Do you have that? Or is this less a function
of Jaxx, and more a function of the toolkit you are using?

You were mentioning that you wanted to create a real application to
demonstrate Jaxx' capabilities. When I was doing this sort of thing, I
created a visual layout tool using the tool itself. Also a mechanism for
creating Presentation classes, and specifying their attachment to the
GUI. Building the builder with itself, we called it. Others refer to
this as eating your own dogfood. It's great for this sort of
application.
