Hi Vampirbcn,

Thank you so much for this library .

One Kind Request.

1. Can you Please add a method by which we can set the height (BubbleLabel.Height)of each label. This will help to adjust the height based on the text it has.

2. The Bubble Label Click function you mentioned is not working. Kindly give us the right Click Syntax.

3. It would be great if you can add BubbleLabel.Top and BubbleLabel.Height. This would be of great use when setting the inner height of scrollview on which the bubble labels are created.

Regards,
SK

Hi Vampirbcn

I like your library but I could not get thebubble_Click to work, is there an update to your library for this.
I am using your sample program to test.
