Introduction

This is an example of dialog creation with PySide.

In this example, the entire interface is defined in Python. Although this is possible for small interfaces, for larger interfaces the recommendation is to create .ui files through Qt Designer, and load these in the program. See Interface creation with UI files.

Use QColorDialog to get a color

Complete code:

# -*- coding: utf-8 -*-
# https://deptinfo-ensip.univ-poitiers.fr/ENS/pyside-docs/PySide/QtGui/QColor.html
import PySide
from PySide import QtGui ,QtCore
from PySide.QtGui import *
from PySide.QtCore import *
path = FreeCAD.ConfigGet("UserAppData")

couleur = QtGui.QColorDialog.getColor()
if couleur.isValid():
    red   = int(str(couleur.name()[1:3]),16)    # decode hexadecimal to int()
    green = int(str(couleur.name()[3:5]),16)    # decode hexadecimal to int()
    blue  = int(str(couleur.name()[5:7]),16)    # decode hexadecimal to int()

    print(couleur)                              # 
    print("hexadecimal ",couleur.name())        # color format hexadecimal mode 16
    print("Red   color ",red)                   # color format decimal
    print("Green color ",green)                 # color format decimal
    print("Blue  color ",blue)                  # color format decimal

Use QColorDialog to create a palette of colors (standard and custom)

This example modify the Standard color and the Customize color with the Tango FreeCAD guide.
