B4J Library jGauges

This is a wrapper for Medusa gauges library: https://github.com/HanSolo/Medusa
License: https://github.com/HanSolo/Medusa/blob/master/license.txt

It includes many types of gauges. The gauges are implemented as custom views.

The gauges can be further customized. You can use JavaObject to access the various methods (see the source code of Gauge.java: https://github.com/HanSolo/Medusa/blob/master/src/main/java/eu/hansolo/medusa/Gauge.java).

Library: www.b4x.com/b4j/files/jGauges.zip

Example is attached.

Updates:

v1.10 - Based on latest version of the open source projects. Includes three new skins (TILE_KPI, TILE_TEXT_KPI, TILE_SPARK_LINE)

Any idea ?

It doesn't crash the program, right?
Looks like an issue inside the library.

Right, work, but every time you click on the button, you get the same problem.
