我有一个带有一个QLabel,一个QLineEdit和一个QPushButton“ Find”的QDialog。按下按钮后,我想将在QLineEdit中输入的文本发送到另一个函数,该函数将处理“查找”按钮的操作。
# shows and handles the find dialog
def handleFind(self):
findDialog = QDialog()
findDialog.setWindowTitle("Find")
grid = QGridLayout()
findDialog.setLayout(grid)
findLabel = QLabel("Find what", findDialog)
grid.addWidget(findLabel,1,0)
findField = QLineEdit(findDialog)
grid.addWidget(findField,1,1)
enteredText = findLabel.text()
findButton = QPushButton("Find", findDialog)
# how to send enteredText as parameter to the find function
findButton.clicked.connect(self.find)
grid.addWidget(findButton,2,1)
findDialog.exec_()
# find function: search in the first column of the table
def find(self):
#to do
names = NvmQtModel.__imp.parameterNames()
如何将在QLineEdit中输入的文本作为参数发送到函数
find
? 最佳答案
您可以使用lambda
发送查找文本,如下所示:
findButton.clicked.connect(
lambda: self.find(findField.text()))
关于python - 使用QPushButton通过按钮发送参数,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/20694129/
