Event for changing attributes

[mluerken]

I'm looking for an event to realize if an field-attribute changes. For example i want to find out if a fieldbias of a button changes from FB_INVISIBLE to FB_LANDABLE.

There is no such an event (though you can send a userevent in the code after you change the bias).

If you just want to know it for debugging purposes you can use the watchpoint feature of the OR2006 debugger, so you can activate the debugger when the value of an exprssion (variable) changes (either for any change or to a specific value).

That was my first idea: calling a procedure or an userevent. But if i have to change attribute very often in our source code, i have to place the codeline after each changing. Having an "attribue-changed-event" will reduce code.
Perhaps i will give this wish to the service desk.

Thank's for your answer.

I'd like to see the same thing in OpenROAD as well. The ability to have either getter/setter methods on user class attributes and/or the ability to have 'on changed' events for attributes.

This actually came from two different requirements, which both came out of wanting to change existing functionality without having to change too much existing code.

1. Being able to take new action when an attribute is changed on a userclass object, without having to re-code existing logic into a method call.

2. As with yourself, being able to code 'generic' Bias changed events into include scripts which would be able to handle application wide changes in Look & Feel.

These features would help in Application re factoring I think.
