Listbox gadget

Does anyone knows how many items a listbox gadget can populate?
Thanks!

It looks like the item index count is held in an int so 2147483647 could well be the limit.

thanks tonyg.

Good luck with that though... I doubt you'll get much response from it if you go anywhere near that kind of figure :-)

Yeah, you would want to break that up into two lists.

Just use a listbox of listboxes, then you can store an infinite amount of items...

Suppose you have to access 1000 items from the hard disk.
Which is the right method to populate a listbox gadget?
Is it right to populate for once or partially while the user browses the listbox?

anyone found a way to speed up adding items to a listbox, it seems realy slow.

@TaskMaster, can you explain a little more?

You may want to have a look at SetDataSource() which is a BETA TGadget method implemented by Skidracer a while back. It supposedly provided a faster way to populate gadget items using arrays, but I have never used it.

Sorry, I was trying to be funny...

If you wanted to populate a listbox with the contents of a directory, I would do it all at once. If a user has a thousand or more items in a directory, they have no right to complain about it being slow to access it.

thanks SebHoll, much faster :)

never mind.

Why a list box is only for reading directory entries?
Which gadget is suitable for reading entries from a data file?

You can list anything you want in a listbox. It was just mentioned earlier in the thread about listing contents of a directory.

ok thats fair, however when you add lots of items to your listbox the visable affect of maxgui while populating the listbox does not look professional. i sorted this by using a cache and loading it when the app starts up, the cache is only updated when the server is refreshed.
