Added OnChange listener
I had the need to know to color the user selected in real time (while he is dragging the color selector) that is before onOk callback gets called so I implement an onChange callback that is called instantly when the user choses a color.
Hi, thanks for your contribution! Do you think that real-time color update is a general scenario which should go into the core library? Sounds more like an edge use case which can be useful for a particular project, but which will just provide an extra empty method to implement for the majority of people.
You are right that could be some overhead code for most use cases. What do you say if I add another interface OnAmbilWarnaLiveListener that extends OnAmbilWarnaListener and this one has all three methods? Just in case anyone else is ever looking for this same functionality...
It makes sense, but one thing that worries me is that onChange
listener is called so many times during color selection, so it can easily become a performance bottleneck. For this feature's potential consumers I would recommend simply putting a comment into existing OnAmbilWarnaListener
which would suggest that it is also possible to add onChange
method to the interface and briefly describe a place in AmbilWarnaDialog
where such method would be called (you could also put a comment inside AmbilWarnaDialog
itself, something like //onChange would be called here
. The comment should also warn a potential user about performance deterioration that the implementation of onChange
may lead to.
