Hi all, I'm developing a small module to display informations about the currently playing song. I'm aware about the Eloquence module : my module is not a replacement of it but just a exercise to learn more about the EFL. I created an .edc file with only one part of type TEXT. I've added an ecore timer in the .c file to check the eventual change of the song. However, the use of edje_object_part_text_set gives me a segmentation fault, crashing e17.
I've attached the .c file and the .edc file. Thanks in advance for your help, Olivier
