A little problem defining a variable

[Jean-Luc Arnaud]

Hi all,

I'm facing a little problem when defining a variable.

My project has two ContainerControls, each of them representing
graphically two objects very equivalent but not totally identical.

In my code, I have to define a variable representing only one of these
objects, but I don't know, when defining it, what object.

Here is my problem: How to define a variable I don't know the type
(Object1 or Object2), based on class ContainerControl?

I tried to define it as ContainerControl, but can't assign it later the
type Object1 or Object2.

I tried to define it as Object1, but can't redefine it as Object2 is needed.

I'm sure the solution is obvious, but can't figure it out.

TIA for your help.

[François Van Lerberghe]

Hello Jena-Luc,

I see 2 ways :
1) you can cast the ContainerControl object :

dim obj1 As Object1
dim obj2 As Object2

if myContainerControlObject isa Object1 then
obj1 = Object1(myContainerControlObject)
elseif myContainerControlObject isa Object1 then
obj2 = Object2(myContainerControlObject)
end if

2) you can use ClassInterface and play with method defined in this ClassInterface

Have a good day.

Thanks for these ideas, François. I will test that.

Have a good day, too. Very hot currently around Paris.

Yes, maybe!

[Jon Ogden]

I had a situation where I had to do this myself and what I did was I created a master subclass for my two objects that had all the “common” items. I then created two subclasses of that custom subclass and put what was different in those.

Now you can treat them as a common subclass of type MySubclassObject for example. But then in your code you can check which you are dealing with using IsA. So your property is of type MySubclassObject but each on is say MySubclassObject1 and MySubclassObject2.

Then you do:

If MyProperty IsA MySubclassObject1 Then

// Do this

Else

// Do something else

End If

Now you can also use class methods and events to help define the master property/variable as well.


Hope this helps.

Something is wrong with these emails. I have one here where it looks like I
can unsubscribe myself and the person who the email was sent to. Also, not
sure why they started coming out individually when they used to be a daily
digest.

Weird.

1.) Xojo moved to a new list server software.

2.) It appears that the digest mode does not exist any longer or maybe needs to be reset.

3.) You don’t get a copy of the emails you send yourself (NOT GOOD).

4.) I see your point about unsubscribing - this is NOT good as well.

Xojo really wants to get rid of the mailing lists and get everyone on the forums

Hi all,
I'm facing a little problem when defining a variable.
My project has two ContainerControls, each of them representing

graphically two objects very equivalent but not totally identical.

In my code, I have to define a variable representing only one

of these objects, but I don't know, when defining it, what object.

Here is my problem: How to define a variable I don't know the

type (Object1 or Object2), based on class ContainerControl?

I tried to define it as ContainerControl, but can't assign it

later the type Object1 or Object2.

I tried to define it as Object1, but can't redefine it as

Object2 is needed.

I'm sure the solution is obvious, but can't figure it out.
TIA for your help.

Thanks for replying, Jon.

I tried that but had some issues. Probably something I did wrong. Well,
will try again.

I think my mistake was to create the SuperClass AFTER creating the
SubClass. I guess I have to do that in the natural way, that is
SuperClass BEFORE SubClass.

Thanks a lot.

In my code, I have to define a variable representing only one of these objects, but I don't know, when defining it, what object.
Here is my problem: How to define a variable I don't know the type (Object1 or Object2), based on class ContainerControl?
I tried to define it as ContainerControl, but can't assign it later the type Object1 or Object2.
I tried to define it as Object1, but can't redefine it as Object2 is needed.
I'm sure the solution is obvious, but can't figure it out.
TIA for your help.

Yes, I would do that. I can send you an example file if you like…

Thanks for replying, Jon.
I tried that but had some issues. Probably something I did wrong. Well, will try again.
I think my mistake was to create the SuperClass AFTER creating the SubClass. I guess I have to do that in the natural way, that is SuperClass BEFORE SubClass.
Thanks a lot.

I had a situation where I had to do this myself and what I did was I created a master subclass for my two objects that had all the “common” items. I then created two subclasses of that custom subclass and put what was different in those.
Now you can treat them as a common subclass of type MySubclassObject for example. But then in your code you can check which you are dealing with using IsA. So your property is of type MySubclassObject but each on is say MySubclassObject1 and MySubclassObject2.
If MyProperty IsA MySubclassObject1 Then
// Do this
Else
// Do something else
End If
Now you can also use class methods and events to help define the master property/variable as well.
Hope this helps.

Hi all,
I'm facing a little problem when defining a variable.
My project has two ContainerControls, each of them representing graphically two objects very equivalent but not totally identical.
In my code, I have to define a variable representing only one of these objects, but I don't know, when defining it, what object.

Yes, with pleasure.

Off list, of course.

Thanks a lot, Jon.
