我是靠谱客的博主清秀镜子，最近开发中收集的这篇文章主要介绍Pyqt - Button，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

Listening 繁华的寂静！

来小例子：

点击AA，BB按钮后会弹出文件选择框，点击Show按钮后会弹出文本输入框，输入后点击确认，然后你输入的东东显示在右侧的显示框框。

Show me the code: -- ui框架的力量啊：

import sys
import os
from PyQt5.QtWidgets import (
    QWidget, QMainWindow, QPushButton, QLineEdit, QInputDialog, QApplication, QFrame, QColorDialog,
    QVBoxLayout, QSizePolicy, QLabel, QFontDialog, QTextEdit, QAction, QFileDialog
)
from PyQt5.QtGui import QColor
from PyQt5.QtGui import QIcon
import compareData


class MyForm(QMainWindow):
    def __init__(self):
        super(MyForm, self).__init__()
        self._init_ui_1()
        self.file_a=''

    def _init_ui_1(self):
        self.btn = QPushButton('AA', self)
        self.btn.move(20, 20)

        self.btn2 = QPushButton('BB', self)
        self.btn2.move(20, 60)

        self.btn3 = QPushButton('Show', self)
        self.btn3.move(20, 120)

        self.btn3.clicked.connect(self.showDialog_1)
        self.btn.clicked.connect(self.a_file_sel)
        self.btn2.clicked.connect(self.b_file_sel)

        self.le = QLineEdit(self)
        self.le.move(130, 120)

        self.setGeometry(800, 300, 500, 300)
        self.setWindowTitle('Input dialog')
        self.show()

    def showDialog_1(self):

        text, ok = QInputDialog.getText(self, 'Input Dialog', 'Enter your name:')

        if ok:
            self.le.setText(str(text))
        else:
            self.le.setText(str(ok))

    def a_file_sel(self):
        # Please do not: self.QFileDialog.getOpenFileName,because this will cause break down
        fileName, fileType = QFileDialog.getOpenFileName(self, "data", os.getcwd(), "All Files(*);;json Files(*.json)")
        self.file_a = fileName
        print(self.file_a)
        print(fileType)

    def b_file_sel(self):
        fileName, fileType = QFileDialog.getOpenFileName(self, "data", os.getcwd(), "All Files(*);;json Files(*.json)")
        print(fileName)
        print(fileType)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    form = MyForm()
    sys.exit(app.exec_())
    pass
