[QGIS-Developer] How to transfer data between QGIS Python plugins?

[Ismail Sunni]

Hi Zac,

In PyQGIS you can access the plugin using something like this:

the_plugin_a = qgis.utils.plugins['the_plugin_a']

After that, you can access all stuff in the plugin a.

Perhaps that can solve the problem.

Best Regards
