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

[vuott at tutanota.com]

...now let's do an analogous example, but with checkbox array:

[code]
Private ccbb As New CheckBox[4]

Public Sub Form_Open()
  
  For b As Byte = 0 To 3
    With ccbb[b] = 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()

  ccbb[2].Background = Color.Red

End
[/code]
