[RESOLVED] Is it possible to nest properties ?

[KBConsole]

In this case I have a point (HexLocation) which I want to get/set as property for my class.

Private HexLocation As Point
 
    Public Property Location As Point
        Get
            Return HexLocation
        End Get
        Set(HexLocation As Point)
        End Set
    End Property

Then this works just fine afterwards:

Hexagon1.Location = New Point(0, 0)

The problem comes when trying to modify only one of those two values, for example:

Hexagon1.Location.X = 33

"This expression is a value and cannot be the target of an assignation."
So I then tried nesting properties but created a demon:

This didn't work either:

I can't simply have it as a public variable because I need to execute code when it is modified but not enough for it to require a method, I think, so I'm lost.

The Point data type is a Structure, and therefore cannot be edited. Instead you need to replace it with a whole new value, eg:

    Public Property X As Integer
...
        Set(NewX As Integer)
            HexLocation = New Point(NewX, HexLocation.Y)
        End Set

Thanks for the tip, that would work great except it would be acessible this way:

Hexagon1.Location = New Point(0, 0)
Hexagon1.X = 33

But I would want X to be a member of Location as such:

Hexagon1.Location = New Point(0, 0)
Hexagon1.Location.X = 33

In that case either create a new Class with similar properties to Point (and use that instead of Point), or possibly call the new property LocationX (and live without the dot).

Thanks I created a structure for it similar to point but with the property blocks I needed.
Also the last reply got sent twice mb.

Can you show us your code because I don't see how that could work either.
