Créer un widget avec une couleur spécifiée avec Python + Qt (PySide)
J'ai créé un widget à couleur spécifiée, qui est indispensable lors de la création d'outils de peinture et est l'une des choses pas difficiles mais ennuyeuses.
C'était gênant d'écrire la mise en page moi-même, donc j'ai fusionné la sortie de Qt Creator et l'ai utilisée.
J'ai enregistré la source sur GitHub. https://github.com/tokyo-noctambulist/colorpicker.git
(Mis à jour le 07/03/2017) Modification de la valeur transmise par référence lors de la spécification de la couleur à copier

Dans sample.py, les deux sélecteurs sont liés et affichés.
Brève explication
Je me suis inscrit auprès de PyPI. Vous pouvez l'installer avec pip etc.
function
pip install colorpicker #install
from colorpicker import *
colorSet = QColorSetWidget(self)
color = colorSet.getColor() #Obtenez de la couleur
colorSet.setColor(QColor(255,100,10,200)) #Définir la couleur
colorSet.colorChanged.connect(onUpdateColor) #signal-slot
