Was helping a fellow Xojo user to try & sort out why updating to a new version of Xojo broke their code.
The code still compiled fine. But it just didnt work as expected any longer.
And it turns out that in some classes Xojo changed a get/set pair of methods, which can be overloaded by a subclass, into actual computed properties, that cant be.… Read the rest
In the case I described the code is in a subclass a Xojo class
The idea here is to INSERT a new subclass between the existing subclass and the new one. And the newly inserted subclass will expose things in a way the OLD existing code wont break
So we never touch the old code
We just modify the inheritance chain in a way we can then alter how things behave
So in his case we can add a new subclass of EmailMessage that exposes the Source as a Method pair ( get & set) and then make the existing class inherit from our new class
And the existing code will then JUST work without ever having had to alter any of it
Next time you have an issue like this consider that as an option !
For the past 3 days I’ve been on a training course and today I got my certification as a CSIA level 1 instructor !!!!!
The other day I was helping a friend with some code that worked fine in several versions of Xojo but then in a newer one wouldn’t compile
Seems he found a compiler regression Whether this _should_ have been caught by regression tests etc is an entirely different question.
It exists. And now his large project doesn’t compile.… Read the rest
Was chatting with a potential client. And they are new to Xojo.
When I mentioned that I had worked at Xojo Inc for more than 10 years they didn’t believe me. And they asked for some proof. I had never encountered this before.
So here’s a quick few references where you can see that I was once a member of their development team.… Read the rest
