本期GUI界面，我们继续学习新的控件Qprogressbar。知识回顾 1.滑动控件qslider 控件设置的关键：设置最大值、最小值，绝对范围。 2.核心类库QtCore,枚举类Qt 核心枚举类的使用，可以帮助我们对代码的理解。一、进度条的使用思想进度条qprogressbar 使用思想： 1.载入类库 2.初始化类对象 3.设置最小值和最大值 4.时钟的使用QBasicTimer，槽方法对应类库的timerEvent 5.判断什么时候停止加载进度条这里我们在学习使用进度条的时候，必须要结合使用时钟控件，这样才能让我们看到进度条动的感觉。二、制作案例说明如下： 1.界面由进度条和按钮组成 2.进度条的值范围为0~100 3.按钮的状态为“开始”、“停止”、“完成” 4..按钮需要能够控制进度条的运行三、开发过程知识点介绍 1.导入时钟类 from PyQt5.QtCore import QBasicTimer 2.初始化进度条 self.pgb=QProgressBar(self) 类对象的初始化 self.pgb.move(50,50) 将进度条移动到指定位置 self.pgb.resize(300,20) 设置进度条宽高 3.设置进度条的范围 #设置进度条的范围 self.pgb.setMinimum(0) self.pgb.setMaximum(100)

QProgressBar部件为进度条，进度条方向为水平或者竖直。在处理一个耗时较长的任务时，可能就会用到进度条部件。因为使用进度条可以形象告诉用户当前的任务正在进行中。进度条常用函数如下：函数值内容 setInvertedAppearance True/False 设置进度条的走向。 Ture：从左至右或从上到下 False:从右至左或从下到上默认为True setOrientation Qt.Horizontal/ Qt.Vertical 设置进度条为水平、竖直。默认为水平 setMinimum 0~99 设置最小值，默认0 setMinimum 0~99 设置最大值，默认99 setFormat ％p ％v ％m 设置进度条旁的文本显示：以百分比表示；以当前值表示；以总步长表示。默认为百分比（%p）。示例如下： 1 import sys,time 2 from PyQt5.QtWidgets import QApplication, QWidget, QProgressBar, QPushButton,QVBoxLayout 3 from PyQt5.QtCore import Qt 4 5 6 class Mywin(QWidget): 7 def __init__ (self): 8 super(). __init__ () 9 self
