這篇文章主要介紹了PyQt5 PySide2 觸摸測試功能的實(shí)現(xiàn),本文通過示例代碼給大家介紹的非常詳細(xì)，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友可以參考下

一、前言

該測試功能是Linux產(chǎn)測軟件的一個(gè)子功能，主要涉及：
140行代碼
PySide2的Event、信號(hào)和槽、QLabel，QWidget。
QLabel實(shí)現(xiàn)每個(gè)小框，QWidget作為主界面

另外發(fā)現(xiàn)PySide2和Pyqt5沒啥大區(qū)別，只要把import的包改好，代碼是可以兩方通用的。

手指滑動(dòng)，手指坐標(biāo)所在方塊的顏色發(fā)生改變，如果手指劃出方塊區(qū)域，則所有已染色方塊清空顏色，松開事件同理

實(shí)現(xiàn)效果：

請?zhí)砑訄D片描述

二、實(shí)現(xiàn)思路：

1.使用GridLayout,繪制四周方格，方格初始化為黃色，點(diǎn)擊到則為紅色

2.重寫Label，對每個(gè)label定義x,y表示所在gridlayout中的位置
如x = 1,y = 3表示label位于第一行第三列，left,right,top,bottom表示方格四條邊的實(shí)際坐標(biāo)

3.重寫moveEvent事件和ReleaseEvent事件，
moveEvnet事件：
每次鼠標(biāo)移動(dòng)即觸發(fā)moveEvent,則發(fā)出已經(jīng)定義的信號(hào)move_signal
move_singal.connect(self.manager_touch)
manager_touch是判斷當(dāng)前鼠標(biāo)是否位于方格內(nèi)，如果在方格內(nèi)則染色，如果鼠標(biāo)劃入空白部分，則清空所有方塊顏色
另對染色label進(jìn)行計(jì)數(shù)，如果達(dá)到繪制的label的總數(shù)量則發(fā)出信號(hào)返回測試通過

ReleaseEvent事件：
鼠標(biāo)左鍵松開（對應(yīng)手指離開屏幕）即觸發(fā)ReleaseEvent，則清空已染色方塊，另把已染色方塊數(shù)量清零

4.clear_sources: 在退出頁面前應(yīng)將保存label的列表即self.touch_labels清空，否則重啟該界面會(huì)報(bào)錯(cuò)

三、實(shí)現(xiàn)代碼：

sytle.py

COLOR_RED = "color: rgb(255, 255, 255); background-color: #FF0000;"
COLOR_YELLOW = "color: rgb(255, 255, 255); background-color: #FFFF00;"
COLOR_WHITE = "color: rgb(255, 255, 255); background-color: #FFFFFF;"
COLOR_BLACK = "color: rgb(255, 255, 255); background-color: #000000;"
COLOR_GREEN = "color: rgb(255, 255, 255); background-color: #00FF00;"

COLOR_PURPLE = "color: rgb(255, 255, 255); background-color: #871F78;"
