问题 I had drawn up an UI using the QT Designer but found out that there are no parameters for me to set QLineEdit inputs to be uppercase. After doing some online searching, I have only seen a very few handful of results that cater to my needs, however all are coded in Qt. Example, this link And so, are there ways for me to do this in the pythonic way? 回答1: Try this, I believe this serves your purpose. I won't call it much pythonic. More like PyQt override. #minor code edit from PyQt4 import QtGui

问题 I have a QListWidget and a QTreeWidget and I want to be able to drag one or multiple list items around within each one as well as between them. I have the internal drag and drop working, but I'm not sure how to drag between them. When I print event.mimeData().formats() in my code below it says ['application/x-qabstractitemmodeldatalist'] . I am stuck on how to extract the text and index of that item (it should be a QListWidgetItem or QTreeWidgetItem, right?) so I can delete the original from

问题 The following Python 3 resp. UI XML code shows 4 QProgessBar for each mouse direction (labeled X+, X-, Y+, Y-). Fast mouse movements (in circles) will make the 4 QProgessBar move up to 99% and then some of the QProgessBar take a break until the mouse movements are slowed down to finally reach 100%. What's the reason for this behavior ? How can the code be fixed so that no QProgessBar takes a break at 99% ? main.py import sys from PyQt5.QtCore import Qt from PyQt5.QtGui import QCursor from

问题 I'm trying to add rows to a table from Python. I'm using a TableView described with QML. I can't figure out how to add a model to the table, unless the model is also in QML. But I can't figure out how to add values to the model. import sys from PyQt5.QtCore import QAbstractTableModel, QObject, QUrl from PyQt5.QtQml import QQmlApplicationEngine from PyQt5.QtQuick import QQuickView from PyQt5.QtWidgets import QApplication myApp = QApplication(sys.argv) engine = QQmlApplicationEngine() context =

问题 I want to show a loading gif until a function is completed. The code I have is self.LoadingGif = QtGui.QLabel(MainWindow) movie = QtGui.QMovie("hashUpdate.gif") self.LoadingGif.setMovie(movie) self.LoadingGif.setAlignment(QtCore.Qt.AlignCenter) self.gridLayout_2.addWidget(self.LoadingGif, 4, 1, 1, 1) movie.start() self.MYFUNCTION() The problem is that the gif shows but it is not playing. It starts to play only when the function is completed. How can I make the gif play while the function is
