Bait & switch ?

in this youtube video posted from the recent Developer Retreat
https://youtu.be/mWEH0kjXZiA?t=2091
geoff talks about the roadmap in the screen shot below I took a screen shot since I knew it was going to change.

Items highlighted in red have disappeared from the new roadmap

Yet, on the testers channel, they already had a complete replacement for it
(also screen shot when I learned of this)

I was more surprised that they talked about it in the keynote knowing that the roadmap was going to change and drop many items.… Read the rest

2019r3

I’ll admit that I really haven’t seriously touched R3 since most of its focus was on iOS and dark mode which isn’t something that matters to me.

The times I did start it I found it to still be slow like R2.1 and otherwise not many significant differences in the things I was trying.

Autocomplete is still glaringly bright in dark mode on macOS.… Read the rest

Operator_Convert

Operator_Convert is a very handy method to implement on a lot of classes. It not only lets you create a mechanism to make your classes convert themselves into other types but it also lets you create new instances FROM other data types.

So let’s start with the simple forms of operator_convert – the “convert TO” forms.… Read the rest

Thanks !

Flat out I’ll say Thanks to Xojo for the 2.1 decision to revert the event name changes. Of all the changes that one was probably the hardest one to deal with as there’s no easy way to #if around an event definition or event handler.

Properties may still cause some grief if you start a project in 2019r2 or r2.1 since they don’t retain the “old” values” so going back to an old version can be tricky if you start in 2019r2 or 2.1.… Read the rest

Spot the bug

You might run into this one from time to time. I know it has bitten a LOT of people and it’s not intuitive at all.

In a new desktop app add a new Class. The default name of Class1 will work fine. And create a new subclass of this. Again the default of CustomClass1 will work fine.… Read the rest

About incremental compilation

There are ways to see what is / isnt being recompiled

Its one of those many temporary files xojo creates

First thing you need is the PID of the specific instance of xojo you’re interested in.
It makes life simpler IF you just run one version at a time
Once you start Xojo you can look in Activity Monitor & get its PID

If you find the dir referred to by SpecialFolder.Temporary… Read the rest

ByVal and ByRef

A recent thread on the forums made it clear there is some lack of clarity about ByVal and ByRef

So here’s yet another attempt.

Value types are ones that the data assigned to them is stored right IN the memory location the compiler set aside for them.

A statement like

dim i as integer

reserves a spot in memory when you compile.… Read the rest

Final(ly)

Some languages have to notion of FINAL for methods, events, properties and many other aspects of the language.

But what exactly does FINAL do or mean ?

In other languages, like Java, FINAL has other uses like creating “constants” which there is no need for in Xojo. In those languages a FINAL property is a constant.… Read the rest
