A DUH! question that should be a snap

[elitistnot]

I know this is going to be one of those DUH! question that should be snap for anyone with a little bit of experience with B4A, being new to it I'm still figuring out the basics;

How do you access the properties of objects (views or whatever they are called) within code?

Something like;

label1.text="Testing"

does not work. So, what am I doing wrong here? How can I change the text of the label within the code?

Thank you for answering my DUH! question, but I can't seem to find an answer in the B4A help document.

Actually the line you posted is correct, of course, if you've declared that label, for example, this will change the text of the label:

Sub Globals

    Dim Label1 As Label

End Sub

Sub Activity_Create(FirstTime As Boolean)

    Label1.Initialize("")

    Activity.Addview(Label1, 0dip, 0dip, 320dip, 40dip)

    Label1.Text = "Hi There"

End Sub

Ok, so the objects created in the Designer are not auto Declared?

Ok, so the objects created in the Designer are not auto declared?

Or is the label1 you declared in code a different label1 from the one created in the designer?

Just sorting out the confusion in my head. I was assuming the objects created in the designer were auto declared in the code. I guess I am wrong there.

See, what I am getting at is if I create a label (named label1) in the designer, how can I change the properties (such as the text) in the code in various Subs?


Thanks.

When you create a view in the designer you have to click on Tools -> Generate members, that will create the line you see in Sub Globals in my sample (Dim Label1 As Label).

The views in the designer are not auto-declared but auto-initialized, you should read the documentation to get a better understanding, is not really difficult.

Ahhh....

Ahhh.... See I knew is was a DUH! question. Thanks for helping with that. Your help is very much appreciated.

Now, I am off to work on my program feeling idiotic... but all the wiser thanks to you!
