__Delete is not called for any object which has the key "__Class". Class objects have this key by default.

counter := new SecondCounter
Msgbox, % counter.HasKey("__Class") "`n" SecondCounter.HasKey("__Class")
counter.Start()
Sleep 5000
counter.Stop()
Sleep 2000
counter =   ; I would expect a ToolTip to show up as a result of this operation
Sleep 2000
Return

; From https://autohotkey.com/docs/commands/SetTimer.htm#ExampleClass

class SecondCounter {
   __New() {
     this.interval := 1000
     this.count := 0
     this.timer := ObjBindMethod(this, "Tick")   ; of this.Tick.Bind(this)
   }
   Start() {
      timer := this.timer
      SetTimer % timer, % this.interval
      ToolTip % "Counter started"
   }
   Stop() {
      timer := this.timer
      SetTimer % timer, Off
      ToolTip % "Counter stopped at " this.count
   }
   Tick() {
      ToolTip % ++this.count
   }
   ; This function is the only addition to the example
   __Delete() {
      ToolTip Deleting object ...
   }
}

__Delete is not called for any object which has the key "__Class" or contains a bound method. Class objects have this key by default.

I agree that the quote from the docs is not relevant. What I am trying to say is that the docs are incomplete. In my opinion, it would be useful to alert the user of a condition where __Delete is not called.

Cheers!

class SecondCounter {
   __New() {
	;[...]
	ObjBindMethod(this, "Tick")
	this.that:=this			; Another self-reference that needs to be deleted before __delete() can be called	
   }

although i don't see any harm with docs being more verbose rather than concise. repetition is not a Bad Thing when it comes to docs. it just makes information easier to find and reinforces the learning of the reader, and as a result reduces help questions in the forum

Code: Select all

delete the object?

Counter := []
Counter := ""
ListVars
MsgBox, % IsObject(Counter)

Counter := []
OtherVar := Counter
Counter := ""
ListVars
MsgBox, % IsObject(OtherVar)  ; Object is not freed because a reference still exists.

1. Deleting an object requires freeing all its references (now I understand guest3456's reference to freeing objects)
2. SetTimer stores a reference to objects internally and that reference is freed only with a SetTimer, Label, Delete command

When an object is destroyed, including freeing all its references to release the object, __Delete is called. Note that, if the label name in a SetTimer command is a reference to a function object that is part of the object, the reference can only be freed with a SetTimer, Label, Delete command.

I feel this would be an extremely efficient way to ask/answer questions on very specific areas of AHK and clarify the meaning of the scripts as well for all page visitors.

I know this is probably an enormous task, but just figured I'd throw it out there because I always have small questions that I'm sure could be very quickly answer with such a technology. Until then, I'll keep browsing the forums and documentation!

This is a great idea, and something that PHP does. At the bottom of all of their online docs pages, users can add their own comments, and quirks, and gotcha's. Actually now that I think of it, even MSDN has this

The escape sequences `s and `t may be used if leading or trailing spaces/tabs are needed in one of #IfWin's parameters.
