aah okay. But that could be solved easier then catching the entire event I suppose. Just add the icons in place inside your ion-item. Then hide them through css.
If you look at the HTML of the opened sliding-item, you notice these specific classes:
item-wrapper active-slide active-options-right
So, on the top level you have active-options-right (if sliding-item is opened on the right side), and active-options-left (if sliding-item is opened on the left side). Just change the display property inside the item for the corresponding icon.
If you don’t want to use options but just detect if an item is sliding at all, you could use the classes active-swipe-left and active-swipe-right.
