Hello, A question about templates : In a 'data-field window' of my patch, I need two types of elements :
- fixed elements, just created with simple templates and no variable, and
classic object boxes (I can have to redraw them occasionally).
- scalars, some objets created with 'append' from the same template
(polygons that can be moved with the mouse to change some values)
I know I can send a 'clear' message to the data window to clear it's content. But I'd like to clear the scalars only, and keep the fixed elements. (I noticed it's easy to do the opposite: clear the content of every template, and keep the scalars)
For a kind of gui-patch, I need to reorganize my scalars, so to clear them and append them again, but I don't want to clear everything in the data-window and 'redraw' everything.
Is it possible (I mean with Pd-0.34) ? Does Pd-0.35 handle this kind of thing better ?
Thank you, and apologies for my previous post, I was just amazed and happy to discover all the new features in the last test-release. :)

Hi Nicolas,
You can't selectively clear part of a window... I'm curious why you want to though... are you by any chance using the deadly "namecanvas" object? I'll do anything to get people to stop using that one...

No, I don't use namecanvas (pd-messages are ok). I attempt to do some gui stuff with templates. It's possible to clear the data window and object list with a "clear" message to the window, but in a graphic interface, it's usefull to be able to delete or redraw some objects, without clearing it all and redrawing.
(I still don't master the templates terminology well. In what follows, a "graphic object" is a displayed scalar.)
Another thing is to get some fixed objects (that you can't modify with the mouse) in the data window. With pd-0.34.2, I noticed it was possible to add this kind of objects (like a drawpolygon object with fixed values) by sending a message ("pd-template obj X Y ... ... ...") to a template window. The data window was automagically updated, the same if I removed the drawpolygon object box (a bit tricky, but better than nothing :).
Last days I spent some time with templates on pd 0.35, "struct" is a good thing (and all the related bugfixes too) but actually I can do less than before (may be some of it is on your todo list).
I know that a more complete gui-toolkit is not a priority for Pd, but here is my little wish-list:
- a "remove" object (the opposite of "append")
- a parameter to append some graphic objects which can't be modified with
the mouse in the data window, but which you can set parameters to from the patch
- even better : a "focus" method for objects that need to be redrawn on a
the front layer.
- a mechanism to 'point' easily to a graphic object (named scalars ?)
