RibbonCanvas.HideButtonLeft
From Jeremie Leroy - XOJO Controls Wiki
Property (As Integer)
Left position (in pixels) of the HideButton. If set to 0, the Left position will be at the far left. If the Value is greater than the width of the RibbonCanvas, it will be displayed at the far right. To keep the HideButton at the far left whatever the width, set a big value such as 99999. Use the ShowHideButton property to set the visibility of the button.
