You can take the data from a table sqlite?

Yes. You can issue a query with Command.ExecuteReader and then go over the results and and the items to the list.

Is it possible to add text alignment to the item properties ?

I am using text padding to do it but alignment would be much nicer :

item.TextPadding = (2*form4.Width/3 - StrLength(item.Text) * 7) / 2

Thanks

We thought about it, but then, what would the exact preferences be? Suppose I align left (right in your case...), than should the list attach the text to pixel x=0? Same goes with top - I guess nobody wants to attach the text right to the very top of the item. So you must allow some padding. It got too coplicated at a certain point, so I preferred letting the programmer the absolute freedom. What do you think? I may be wrong. What I can do, anyhow, is to add TextCeneredPadding method that will return the x position for centring the text on a given default. You will have to recalc when you change the font/text, but that's usually rare. I would be glad to have suggestions.

I think it should work in the same way as in textbox (in which I don't know how it is implemented ), so you shouls allow for 2-3 pixels on each side , or half the font width, something like that.

I didn't think about vertical alignment - I believe ther the padding is enough.

Another problem:

The clicking on the device for activating an item requires a very hard tick. is it possible to play with the sensitivity of it ? I guess you control the difference between a click and a touch for moving the list.
Edit: I checked again and found that the click on the device just needs to stay a little bit longer on the item in order to activate it smoothly. No need to change anything.

In many cases the text will be displayed together with an image. A simple alignment such as the textbox alignment will not be powerful enough.

You can use ImageLib.StringWidth to find the exact width of the text.

As for the Click event you mentioned: I agree there is a fine tuning required there. There is actually a threshold for the minimal amount of time without movement that differentiates between a tick and the initial touch of a movement. If it's too short every touch raises the tick. I agree it's a bit too long now.

Thank you both for the info and advice.

I was not aware of the stringwidth function, but I don't think I need to be so exact.

Here is how I use the list with images in my family tree program. I like this library

derez - it's looking good!

I have been waiting for a control like this - can't wait to try it!
