Summary

Slider - Overflow error

Type             : Bug
Priority         : Medium
Gambas version   : Unknown
Product          : GUI components


Description
-----------

This issue only occurs in Gambas 3.20.? (Note:- The Gambas version on the 'Bug Report' does not have 3.20 in the dropdown list)

If you run the code below then move the slider, an "overflow" error occurs at about 25% along.
To avoid this being an error on my PC only I asked other users to check, and they found the same issue. See here: - https://forum.gambas.one/viewtopic.php?t=1963

Public Sub Form_Open()
  
  Dim Slider1 As Slider
  
   With Me
    .Arrangement = Arrange.Vertical
    .H = 40
    .W = 1000
    .Padding = 5
  End With
  
  With Slider1 = New Slider(Me)
    .H = 28
    .MinValue = 0
    .MaxValue = 16777215
  End With
  
End
