[Gambas-user] How to create an array of checkbox?

[vuott at tutanota.com]

I did not use an array.

With my code you have to identify a feature, more specifically a Property that identifies the graphic Object, whose background color you want to change.

Example:
[code]
Private cb As CheckBox

Public Sub Form_Open()
  
  For b As Byte = 0 To 3
    With cb = New CheckBox(Me) As "CheckCheck"
      .X = (b + 1) * 70
      .Y = 100
      .W = 50
      .H = 10
      .Name = "CheckBox n. " & CStr(b)
    End With
  Next
 
End

Public Sub CheckCheck_MouseDown()
 
  Print Last.Name
 
End

Public Sub Button1_Click()

  Dim ob As Object

  For Each ob In Me.Children
' Identify the name of the first "CheckBox" and changes its background color:
    If ob.Name = "CheckBox n. 0" Then ob.Background = Color.Red
  Next

End
