PyQt5 PySide2 触摸测试功能的实现代码

一、前言

该测试功能是linux产测软件的一个子功能，主要涉及：

140行代码

PySide2的Event、信号和槽、QLabel，QWidget。

QLabel实现每个小框，QWidget作为编程客栈主界面

另外发现PySide2和Pyqt5没啥大区别，只要把import的包改好，代码是可以两方通用的。

手指滑动，手指坐标所在方块的颜色发生改变，如果手指划出方块区域，则所有已染色方块清空颜色，松开事件同理

实现效果：

二、实现思路：

1.使用GridLayout,绘制四周方格，方格初始化为黄色，点击到则为红色

2.重写Label，对每个label定义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表示方格四条边的实际坐标

3.重写moveEvent事件和ReleaseEvent事件，

moveEvnet事件：

每次鼠标移动即触发moveEvent,则发出已经定义的信号move_signal

move_singal.connect(self.manager_touch)

manager_touch是判断当前鼠标是否位于方格内，如果在方格内则染色，如果鼠标划入空白部分，则清空所有方块颜色

另对染色label进行计数，如果达到绘制的label的总数量则发出信号返回测试通过

ReleaseEvent事件：

鼠标左键松开（对应手指离开屏幕）即触发ReleaseEvent，则清空已染色方块，另把已染色方块数量清零

4.clear_sources: 在退出页面前应将保存label的列表即self.touch_labels清空，否则重启该界面会报错

三、实现代码：

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_BLUE = "color: rgb(255, 255, 255); background-color:  #0000FF;"
COLOR_PURPLE = "color: rgb(255, 255, 255); background-color: #871F78;"
