obviously i’v didn’t understand very well OOP
I need to create dictionary that can be read/write by other method
It work only with
dim d As new dictionary inside a method
Won’t work when i create dictionary in property… with no New before
Create a property called mDict, and set it to be of type Dictionary.
Create computed property called Dict, and set it to be of type Dictionary.
Implement the Get part of the computed property:
If mDict Is Nil Then
mDict = New Dictionary()
Now you can use Dict in different methods.
It work… of course you knew
but can you tell me why it’s so complicate
( not very… but more than create a integer in property )
It’s not really all that complicated. Integers, Doubles, Colors, Currency, Strings and a handful of others are native datatypes that only need to be declared with the dim statement.
dim i as integer
The dictionary is a class that has to be instantiated with the new command. There are MANY examples of this in Xojo. There are too many classes to list.
dim d as dictionary
d = new dictionary
Or combined into one line
dim d as new dictionary
This is where using the Xojo Language Reference can be helpful (Look in the help menu). It will have examples of how to use everything.
