Hi,
The short question is: How do I add a button to the toolbar in Ptolemy.
I'm working on a add-on for ptolemy to do some specific actions. The goal is for users to click the to-be made button and then let the magic happen: validation of some values against a database. The huge amount of code dazzled me :) Where do I start with extending vergil/ptolemy to fit my needs?
The simplest way to do this is to define an attribute that you drop into your model where double clicking on your attribute invokes your magic. Below is an example of such an attribute that in this case opens its own, custom UI for a verification tool called Chic.
You can also add buttons to the toolbar, but doing so is more involved. You need to subclass the ActorGraphFrame to add to the toolbar, and ActorGraphTableau, which creates the ActorGraphFrame (both in $PTII/ptolemy/vergil/actor). Then you need to create a Configuration (like those in $PTII/ptolemy/configs) to create this tableau rather than the default one.
This latter mechanism is intended for much more drastic changes to the UI than just adding a button to the toolbar (you can create a completely custom UI for a model this way).
Hope this helps... Edward
----------- the attribute that you drop in your model:
public class ChicInvoker extends Attribute {
/** Construct an attribute with the specified container and name.
* @param container The container.
* @param name The name of the attribute.
* @exception IllegalActionException If the factory is not of an
* acceptable attribute for the container.
* @exception NameDuplicationException If the name coincides with
* an attribute already in the container.
*/
public ChicInvoker(NamedObj container, String name)
throws IllegalActionException, NameDuplicationException {
super(container, name); // Create a custom icon.
_attachText("_iconDescription", "<svg>\n" +
"<rect x=\"-50\" y=\"-25\" "
+ "width=\"100\" height=\"50\" "
+ "style=\"fill:white\"/>\n"
+ "<image x=\"-50\" y=\"-25\" width=\"100\" height=\"50\" "
+ "xlink:href=\"ptolemy/chic/chic.gif\"/>\n"
+ "</svg>\n"); // Do not show the actor name.
new SingletonAttribute(this, "_hideName"); // Create the attribute that overrides what you do when you
// double click.
new ChicControllerFactory(this, "_controllerFactory");... }
-------------------------- The controller attribute:
/* An attribute that produces a custom node controller for ChicInvoker.
