How do i extend or overwrite standard methods in sap ui5? sap.m.carousel

[former_member190063]

Hi,

There is a standard method in sap.m.carousel setActivePage() in sapui5 carousel control. How do i overwrite this method. Because this setActivePage method fires an event called pageChanged. Also when they press arrow button , same event gets triggered.

1) setActivePage ----> Trigggers --> pageChanged event

2) Press ArrowButton in carousel --- > Triggers ---- > pageChanged event

Both 1 and 2 triggers same event. I need to identify which one has triggered the event. Is there possibility to overwrite setActivePage method which fires pageChanged event?

You could extend the caroussel Control to a CustomCaroussel and overwrite the method there.

You also could (maybe should) open an incident for feature request. Maybe keeping same event for backward compatibility reasons, but adding a parameter to event payload, which tells the reason why page changed, or something like that.

Hi Segei Haller,

I have created an incident for the issue.

Do we have any working example for overwriting the standard methods in sap ui5 control?
