The current automatically calculated value of cellWidth is set as the minimum value of the slider

There is no special event for that (and onAfterRender/onAfterUpdate are not fired in this case) but you can use onBeforeTimeHeaderRender to check the cellWidth value. The time header will always get re-rendered after the cell width adjustment.
