1、ini参数设置
if not os.path.exists('setting.ini'):
config = configparser.ConfigParser()
config.add_section('Directories')
config.set('Directories', 'last_used_directory', 'c:')
with open('setting.ini', 'w') as configfile:
config.write(configfile)
config = configparser.ConfigParser()
config.read('setting.ini')
last_used_directory = config.get('Directories', 'last_used_directory')
2、打开目录
def get_directory(self, last_used_directory):
# root = tk.Toplevel()
# root.withdraw()
if not last_used_directory:
last_used_directory = os.getcwd()
directory = filedialog.askdirectory( initialdir=last_used_directory,)
return directory
3、ui界面 简单界面，直接用代码实现
class MyApp(QApplication):
FileName=""
def __init__(self, argv):
super().__init__(argv)
self.loop = asyncio.get_event_loop()
self.queue = asyncio.Queue()
self.timer = QTimer()
self.timer.timeout.connect(self.update_text)
self.timer.start(100)
self.initUI()
def initUI(self):
self.window = QWidget()
self.log = QTextEdit()
self.btnOpenFile = QPushButton('打开文件')
self.btnOpenFile.clicked.connect(self.browseFile)
self.btnOutputDir = QPushButton('设置输出目录')
self.btnOutputDir.clicked.connect(self.setOutputDir)
self.btnMake = QPushButton('生成语句')
self.btnMake.clicked.connect(self.on_click)
self.hbox = QHBoxLayout()
# hbox = QHBoxLayout()
self.hbox.addWidget(self.btnOpenFile)
self.hbox.addWidget(self.btnOutputDir)
self.hbox.addWidget(self.btnMake)
self.vbox = QVBoxLayout()
# vbox = QVBoxLayout()
self.vbox.addLayout(self.hbox)
self.vbox.addWidget(self.log)
self.window.setLayout(self.vbox)
self.window.setWindowTitle('数据处理')
self.window.setGeometry(300, 300, 800, 1000)
self.window.setWindowIcon(QIcon('icon.png'))
self.window.show()
if __name__ == '__main__':
import sys
app = MyApp(sys.argv)
sys.exit(app.exec_())
4、复杂的界面，在qtcreator 添加文件-》 qt-》Qt Designer Form
直接加界面和槽函数，参考Pyqt5一小时速成精髓_哔哩哔哩_bilibili中的处理方法。
# This Python file uses the following encoding: utf-8
import sys
from PyQt5.QtWidgets import QApplication,QMainWindow,QWidget,QAbstractItemView
from PyQt5.Qt import QWidget,QApplication,QTableWidgetItem
from PyQt5.uic import loadUi
from PyQt5 import QtCore,QtGui
from PyQt5.QtGui import QPixmap
QtCore.QCoreApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling) #QtCore.Qt.AA_EnableHighDpiScaling
class MainWindow(QWidget):
def __init__(self):
super(QWidget,self).__init__()
loadUi("./form.ui",self)
def slot1(self):
print("aaaaaaaaaaa")
return
if __name__ == "__main__":
QtCore.QCoreApplication.setAttribute(QtCore.Qt.AA_ShareOpenGLContexts)
QtCore.QCoreApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling)
app = QApplication(sys.argv)
app=QApplication.instance()
if app is None:
QtCore.QCoreApplication.setAttribute(QtCore.Qt.AA_ShareOpenGLContexts)
Widget=MainWindow()
Widget.show()
# ...
sys.exit(app.exec())
