bList v0.9 (beta) released

[Erel]

I'm very excited to release the first beta version our new complex list control 'bList'.
Allow me to quote Ariel description from the help manual:

bList is a modern UI element used as a basic list viewer. bList is intended to help creating user interface for touch screens and is specifically suited for Basic4ppc. bList allows finger-based operation and is intended to be used for multi-choice elements, list, and the like.

Moving the list is done by dragging the finger (or a stylus) over the screen. The faster dragged the faster the list moves. Lifting the finger will cause the list to reduce speed to a full stop. Clicking an item fires an event and the programmer can handle it in code.

This is a beta version and I'm sure that there are still some improvements required. Also note that some of the method signatures may change in the stable release.
Any feedback about this new control will be highly appreciated.

Setup instructions:
- Download the attached file.
- Copy bList.dll and bList.chm to the libraries folder. By default:
c:\Program Files\Anywhere Software\Basic4ppc Desktop\Libraries

The zip file also includes several examples.

I want to thank Ariel for writing this cool new library .
Edit: v0.93 is attaches. bListItem.CreateNew2 second parameter can be an empty string for items without an image.
Edit: v0.92 is attached. Improves the 'click' sensitivity on VGA devices.
Edit: v0.91 is attached with some minor bug fixes and corrections to the help manual.
Edit: Example file was fixed.

Forgot to mention that this library requires Basic4ppc v6.80 or newer, and it supports both the desktop and the device.

He erm, he didn't answer...

Erel & Ariel, you're distracting me from the work I should be doing with libraries like this

I'm already thinking of a photo viewer where there will be a thumbnail on the left and Exif data on the right; clicking the thumbnail to give you a full screen of your picture and tapping it again to close...

I think a lot of people will be able to do a lot with this library.

I join to Zenerdiode's comlaint.
I now have to upgrade my already finalized programs with this fantastic list.

Thanks a lot Erel & Ariel !

question: I saw that two list can be located side by side, and run independently. Is there possibility to tie them so that they will scroll together, like a table ?

[Ariel_Z]

It's an interesting feature: I haven't thought about it. I will add it as a consideration for next versions. In the meantime, you can only set a timer that will check list1.IndexFirstShown and then will set list2.IndexFirstShow = x. I must say I did not check if this works and depending on the timer interval and the CPU, I might be a bit awkward and jumpy. It works only in multiplications of "integer items" - that is, it will not scroll them smoothly. You might consider, in the meantime, adjusting the right place for an image that will define a vertical separation bar and set the text so that it's around it. It's a bit awkward programming as well but will give better results for the user.

Thanks Ariel, it is not crucial for me. the simple workaround is to combine the two cells to one text string and show them as on list item.
So, don't break your back for this feature , unless you also think of uses for it.

good work Ariel!Big thanks!
and what about a programmble scroll?

[Ariel_Z]

Do you mean a scroll bar to the right of the list or the ability to scroll the list programmaticaly? To scroll it in code use IndexFirstShown (this actually jumps. Do you need it specifically to scroll to the right item?).

excellent library.

You can take the data from a table sqlite?

Latimer is a run with only 6.80 will need to update
