PyQt5 檔案對話方塊
PyQt5 支援（本機）檔案對話方塊：開啟檔案，開啟多個檔案和儲存檔案。通過呼叫 PyQt5 中包含的函式，你將獲得預設檔案對話方塊，你無需從頭開始重新建立這些對話方塊。你需要匯入 QFileDialog。
PyQt5 檔案對話方塊示例
使用的方法是 QFileDialog.getOpenFileName()，QFileDialog.getOpenFileNames()，QFileDialog.getSaveFileName()。方法引數允許你指定預設目錄，檔案型別和預設檔名。
下面的程式碼將顯示所有檔案對話方塊：
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QInputDialog, QLineEdit, QFileDialog
from PyQt5.QtGui import QIcon
class App(QWidget):
def __init__(self):
super().__init__()
self.title = 'PyQt5 file dialogs - tastones.com'
self.left = 10
self.top = 10
self.width = 640
self.height = 480
self.initUI()
def initUI(self):
self.setWindowTitle(self.title)
self.setGeometry(self.left, self.top, self.width, self.height)
self.openFileNameDialog()
self.openFileNamesDialog()
self.saveFileDialog()
self.show()
def openFileNameDialog(self):
options = QFileDialog.Options()
options |= QFileDialog.DontUseNativeDialog
fileName, _ = QFileDialog.getOpenFileName(self,"QFileDialog.getOpenFileName()", "","All Files (*);;Python Files (*.py)", options=options)
if fileName:
print(fileName)
def openFileNamesDialog(self):
options = QFileDialog.Options()
options |= QFileDialog.DontUseNativeDialog
files, _ = QFileDialog.getOpenFileNames(self,"QFileDialog.getOpenFileNames()", "","All Files (*);;Python Files (*.py)", options=options)
if files:
print(files)
def saveFileDialog(self):
options = QFileDialog.Options()
options |= QFileDialog.DontUseNativeDialog
fileName, _ = QFileDialog.getSaveFileName(self,"QFileDialog.getSaveFileName()","","All Files (*);;Text Files (*.txt)", options=options)
if fileName:
print(fileName)
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = App()
sys.exit(app.exec_())
