Suppose you create a custom canvas:
That canvas has a Getter/Setter pair to retrieve/store a string in
a property. Assume the canvas control is called myCanvas.
Sub SetText( theText as string)
MyText = theText
End Sub
and
Sub GetText() as string
return MyText
End Sub
You call the methods externally as such
myCanvas.SetText("some text")
and
someText = myCanvas.GetText()
Now lets say you make the daring decision to put the canvas control
inside a Containercontrol, but you still need to be able to set/get
the string stored in the canvas externally to the Container.
Is it most appropriate to create a Getter/Setter pair of methods
for the Container Control that passes on the values on to the
myCanvas control?
i.e.
Container control methods:
Sub SetText( theText as string )
myCanvas.SetText(theText)
End Sub
Sub GetText() as string
return myCanvas.GetText()
End Sub
Or is there a better way to do this?
I think that this is precisely what you should do. You'll appreciate
it if, for instance, you decide to rename the canvas. Computed
properties are great for this sort of thing.
