Salut les gens,
bon, j'ai (très) grandement revisité mon widget de batterie. L'apparence habituelle ne change quasiment pas (si ce n'est un affichage plus propre du temps restant (affiche seulement les minutes s'il reste moins d'une heure) mais en revanche, j'ai apporté les modifications suivantes:
- si la batterie atteint une charge infèrieure à 15%, une pop-up de notification rouge apparait avec un message d'avertissement (il m'arrivait de ne pas faire attention à mon widget de batterie...).
- si le voltage est trop faible, une pop-up prévient.
- lors du survol du widget avec la souris, une popup apparait et affiche les informations que l'on peut voir dans les deux screenshots ci-dessous:
Si on sur secteur, on voit ceci:
Si on est sur la batterie, on dispose d'une information supplémentaire nous indiquant depuis combien de temps c'est le cas:
La nouvelle version du widget se trouve sur mon dépôt mais voici le code au cas où:

Bon, ce n'est qu'un début: j'ai prévu de revisiter d'autres de mes widgets en allant dans le même sens. Je vous tiendrais au courant.
Par ailleurs, si vous avez des suggestions d'améliorations intéressantes, je suis preneur. 😉
EDIT: je viens de r'ajouter un % à l'affichage du "health". Il s'agit de l'état de la batterie que je définis en calculant le rapport de la charge maximale que peut avoir la batterie actuellement sur la charge qu'elle pouvait avoir en sortant de l'usine.
