如下面動圖所示，點擊取色按鈕后，將滑鼠移動到想要取色的位置，等待兩秒即可取色：

點擊save color按鈕可以將顏色存盤到color library區域，同時如圖所示，

! ! ! !紅框內所有的方形元件其實都是按鈕，點擊后能獲得顏色資訊 ! ! ! !

資訊格式為：(173, 189, 163) #ADBDA3 (48, 35, 189)

1所需python包

PySide2
pyautogui
pyperclip
ctypes

from PySide2.QtWidgets import QApplication,QWidget,QLineEdit
from PySide2.QtWidgets import QLabel,QPushButton
from PySide2.QtGui import QIcon,QFont
from PySide2.QtCore import Qt

import sys
sys.path.append("...")

import time
import pyautogui as pag
import pyperclip
from ctypes import *

2python小技巧

2.1控制元件陣列

和matlab一樣，python得控制元件也能構成陣列，例如我在創建小顏色框時，是這么寫的：

# 存盤顏色框
for i in range(0,2):
    for j in range(0,10):
        storeColorBox=QPushButton(self)
        storeColorBox.setGeometry((0.04+0.093*j)*Width,(0.475+0.07*i)*Height,0.08*Width,0.06*Height)
        storeColorBox.setStyleSheet(self.SS_Color_Box)
        storeColorBox.setProperty("storeId",i*10+j)
        storeColorBox.setProperty("Color",'#FFFFFF')
        storeColorBox.clicked.connect(self.selectedStore)
        self.storeList.append(storeColorBox)

就是將各個顏色框存入了self.storeList這個陣列，
想要例如想要呼叫第i個顏色框，就可以這么寫：

storeBox=self.storeList[i]

2.2將控制元件作為屬性

將控制元件控制元件作為屬性賦給另一個控制元件
因為我們想要點擊左側標簽時獲得對應文本框內資訊：

在這里插入圖片描述
就可以這么寫（舉個例子）：

# 創建文本框
self.CB1=QLineEdit(self) 
self.CB1.setText("255,255,255") 
self.CB1.move(0.62*Width,0.03*Height)  
self.CB1.resize(0.35*Width,0.065*Height)
self.CB1.setFont(qf)
self.CB1.setStyleSheet(self.SS_Inf_Box)

# 創建標簽
self.CL1=QPushButton(self)
self.CL1.setGeometry(0.448*Width,0.025*Height,0.14*Width,0.075*Height)
self.CL1.setStyleSheet(self.SS_Inf_Label)
self.CL1.setText("RGB")
self.CL1.setFont(qf)
self.CL1.setProperty('Children',self.CB1) # 把控制元件作為屬性
self.CL1.clicked.connect(self.copyInf)# 與回呼函式相連

然后我的回呼函式是這樣寫的：

def copyInf(self):
	infLabel=self.sender()
	infBox=infLabel.property('Children') # 通過找到屬性找到對應控制元件
	pyperclip.copy(infBox.text())

2.3怎樣重設控制元件顏色

還是通過setStyleSheet設定嗷，不過把字串部分應該放顏色的部分換成了要重設的顏色：

self.mainBox.setStyleSheet("QPushButton{background:"+self.curColor_HEX
        +";border: 3px solid rgb(150,150,150);border-radius:8px}")

2.4一些用到的字串操作

字串字母大寫

STR=STR.upper()

字串去掉空格
例如把(10, 50, 255)變為(10,50,255)

STR=STR.replace(" ", "")

字串去掉兩頭括號
例如把(10,50,255)變為10,50,255

STR=STR[1:-1]

2.5滑鼠位置像素顏色

如何獲得當前滑鼠位置像素顏色

import pyautogui as pag
from ctypes import *

x,y=pag.position()
RGB=get_color(x,y)

# 獲取x,y位置像素顏色
def get_color(x, y):
    gdi32 = windll.gdi32
    user32 = windll.user32
    hdc = user32.GetDC(None)  # 獲取顏色值
    pixel = gdi32.GetPixel(hdc, x, y)  # 提取RGB值
    r = pixel & 0x0000ff
    g = (pixel & 0x00ff00) >> 8
    b = pixel >> 16
    return [r, g, b]

2.6視窗始終置頂

self.setWindowFlags(Qt.WindowStaysOnTopHint)

2.7文本框不允許編輯但允許復制

用setFocusPolicy(Qt.NoFocus)，例如程式中：

self.CB1.setFocusPolicy(Qt.NoFocus)
self.CB2.setFocusPolicy(Qt.NoFocus)
self.CB3.setFocusPolicy(Qt.NoFocus)
