sDrop multiple files

Contributed Library Questions

Hi all,

Processing and programming is all very new to me and this is my first question on the forum.

I've been trying to avoid asking question without researching first, but I can't find the answer for this one.

I'll try to be concise without being unclear.

I'm writing a program that uses sDrop, by Andreas Schlegel.

Users drop files and folders onto the sketch. This generates a list that is displayed on the screen.

If the list is bigger than the sketch window, I generate a scrollbar. Users can continuously drop files and folders.

My issue is when the user drops a large amount of files (say 300) at the same time (note that it's not a folder with many files).

For every file, "dropEvent" will register one event and will refresh the list on screen.

For 300 files, this could be a bit heavy, couldn't it?

Is there a way I could refresh the list on the screen only when the group of files I dropped have been loaded?

I hope it was clear enough.

Thanks,

Ennio

By convention, sketches using a contributed library belong to the corresponding section, even though this question is mostly independent of the library (since we don't see code...).

One way is to have a global array list of file paths. You display them by iterating on the list.
On the dropEvent callback, don't refresh the list on screen, just use .add(file) to the ArrayList. Let the draw() to refresh the screen with the current list.

Hi phi.lho,

Thank you so much for answering my question so quickly.

I think I understand what you mean.

I've tried and it works.

I'll clean the code and post in the future.
