这篇文章主要介绍“PyQt5 PySide2触摸测试功能如何实现”的相关知识,小编通过实际案例向大家展示操作过程,操作方法简单快捷,实用性强,希望这篇“PyQt5 PySide2触摸测试功能如何实现”文章能帮助大家解决问题。
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:
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
