我想从导入的lineEdit
文件中编辑.ui
。我不希望将.ui
转换为.py
的代码,因为.ui
会经常更改,转换成.py并从.py导入对我来说似乎是一个较长的过程。
运行代码时,似乎在主窗口中生成了两个单独的lineEdit
而不是一个。可能是由于父类ui
导致的父子类关系,但我不明白为什么?
from PyQt5 import QtCore, QtGui, QtWidgets, uic
import sys,re
import pandas as pd
from glob import glob
import os
ui,base=uic.loadUiType("test.ui")
class MainWindow(ui,base):
def __init__(self, parent=None):
base.__init__(self,parent)
# initializes the user interface
self.setupUi(self)
self.lineEdit=lineEdit(self.lineEdit)
class lineEdit(QtWidgets.QLineEdit):
def __init__(self, parent):
super().__init__(parent)
self.parent=parent
self.setAcceptDrops(True)
self.setDragEnabled(True)
def dragEnterEvent(self, event):
if event.mimeData().hasUrls:
event.acceptProposedAction()
else:
event.ignore()
def dragMoveEvent(self, event):
if event.mimeData().hasUrls:
event.setDropAction(QtCore.Qt.CopyAction)
event.acceptProposedAction()
else:
event.ignore()
def dropEvent(self, event):
mymodel=QtGui.QStandardItemModel()
if event.mimeData().hasUrls:
event.setDropAction(QtCore.Qt.CopyAction)
for url in event.mimeData().urls():
links=url.toLocalFile()
self.setText(links)
return links
if __name__ == "__main__":
if not QtWidgets.QApplication.instance():
app = QtWidgets.QApplication(sys.argv)
else:
app = QtWidgets.QApplication.instance()
MainWindow=MainWindow()
MainWindow.show()
app.exec_()
更改后的self.lineEdit=lineEdit(self)
导致两个独立的lineEdit
,而self.lineEdit=lineEdit(self.lineEdit)
导致两个重合的lineEdit
小部件在主窗口的相同坐标处。
任何帮助都很好...

说明:
您假设使用self.lineEdit=lineEdit(self.lineEdit)
行代替QLineEdit,不行。用另一个变量替换一个变量并不意味着消除了先前的变量,因为先前的QLineEdit的所有权拥有它Qt,在您的情况下,您表示您正在创建另一个QLineEdit,它将作为第一个的子代,因为您传递了parent作为第一个参数,因此它将位于QLineEdit的位置。
解决方案:
如果要在.ui中使用自定义窗口小部件,则必须升级该窗口小部件,为此,您可以关注以下信息:
考虑到上述情况,解决方案是:
├── lineedit.py
├── main.py
└── test.ui
main.py
import os
import sys
from PyQt5 import QtCore, QtGui, QtWidgets, uic
current_dir = os.path.dirname(os.path.realpath(__file__))
Ui, Base = uic.loadUiType(os.path.join(current_dir, "test.ui"))
class MainWindow(Base, Ui):
def __init__(self, parent=None):
super().__init__(parent)
self.setupUi(self)
if __name__ == "__main__":
app = QtWidgets.QApplication.instance()
if app is None:
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())
lineedit.py

您将在
中生成下一个QLineEditself.lineEdit=lineEdit(self.lineEdit)
您可以通过代码使用ui进行操作(例如将占位符QWidget替换为LineEdit,并在构造函数中将自定义行编辑放置在此小部件中,或者您可以在QtDesigner中注册自定义小部件。更多信息,请访问:https://doc.qt.io/qt-5/designer-creating-custom-widgets.html
