Re: [VW] Widegtry 1.0 documentation

Hi,

I would also be interested in documentation about how to build custom
widgets.

Until now, the only documentation I know of consists of the nice how
to's from the blog of Sam Shuster:

Re: [VW] Widegtry 1.0 documentation

All,

The decision to release Widgetry 1.0 was made knowing it would be without updated documentation, and this because
of a number of prioritizations over the previous number of months. The plans at the moment, however, are to do an
update to the documentation and make it available as a web-based document. Updating will start probably
sometime in August, though I don't have an estimate of exactly when it will become available. September might
be a reasonable guess, but it is only that at this point.

What kind of custom widget example would you like?

Re: [VW] Widegtry 1.0 documentation

Hi,

I would like to build a canvas that has scrollbars based on the
bounds of the drawn content, and then I want to use it as a backend
for Mondrian rendering.

Mondrian is an engine for scripting interactive visualizations:
http://smallwiki.unibe.ch/moose/tools/mondrian/

At the moment, Mondrian features Nodes and Edges which are subclasses
of VisualPart, and it uses as a backend a View Holder from the
Wrapper framework.

I guess that I need to have a ScrollingCanvas that perhaps is a
subclass of Canvas and that has scrollbars. I looked a bit at the
code from the other widgets that use scrollbars (e.g., Form) but I
did not understand the entire mechanism yet. I also guess I need to
have an ScrollingCanvasArtist that deals with the current visible part.

As I also need interaction, I also need a MondrianAgent that deals
with dragging and dropping of elements on the canvas.

Any hints are welcome.

Cheers,
Doru

Re: [VW] Widegtry 1.0 documentation

I'd like to see how to do a Canvas with scrollbars too. I have a
CairoCanvas for drawing with Cairo, and at some point, need to add
scrolling to this.

Re: [VW] Widegtry 1.0 documentation [Nice example]

In reply to this post by Samuel S. Shuster <sames@interaccess.com>

Well I would know of a nice Blog example (I love the blog examples).

Imagine a Grid (dataset) which scrolls through a scrollbar which hangs on a custom view. (something like the enclosed image).
Now the dataset is actually the result of a GlorpQuery, so more or less initiated. If I scroll down the view the dataset scrolls in an equivalent way respecting the datasaet grid. Now I could tell glorp to query using limit and offset based on the scrollbar position, the problem is that this does not work on all platforms (both ACCES and SQLServeur ignore offsets) or find a cool way to declare all glorp rows to be un initiated and having the widget decide who is actually called from the database.

Notice that this all does work in wrapper (after having shot yourself in the foot for a couple of times) so it must be an easy job in Widgetry ;-)

Rgrds,

Good! And a very focused requirement!

I have one or two more more basic widget posts to go and then this
would be one to three posts!

It is an interesting proposal since it mostly consists of working
with Scrollbars which are part of the Internal Decoration. This is a
level lower than the "top" API, and a good place to start the drill
down of understanding how Widgetry works.

Thank you all for the suggestion!

And So It Goes
