Notes

Sliders default to a height of 23 pixels so they use the normal size on all platforms.

On macOS Sierra (10.12) and later, vertical sliders no longer appear automatically when the height is greater than the width. To enable a vertical slider, put this code in the Open event handler for the Slider:

Declare Sub setVertical Lib "Cocoa" Selector "setVertical:" (windowRef As Integer, id As Boolean)
setVertical(Me.Handle, True)

Examples

Changing the maximum value of a Slider at runtime:

Slider1.Maximum = 200

Setting the text of TextField1 to the value of the slider when the user scrolls.

Sub ValueChanged()
TextField1.Text = Str(Slider1.Value)
End Sub
