问题 I have a form where i've done a custom field that only accepts the top, right and bottom arrows. But to accept the tab navigation i'm using the following chain of functions: nextItemInFocusChain().forceActiveFocus() The problem is that this is working on windows but not on mac ... I've a formulary to illustrate the problem where next to that "code text field" i have a comboBox where i want, that when the user clicks on tab in the "code text field" to navigate to. It seems that it only

问题 I'm currently working on creating a QML Calendar that will ideally display events from a Google calendar. This is an example of what I'd like to emulate in python: https://doc.qt.io/qt-5.9/qtquickcontrols-calendar-example.html Right now, a python file is taking dates and event summaries from the Google Calendar API and returning them as a dictionary (the tenevents variable in the python code) of {date: event summary}. I have a very simple QML window displaying a calendar and a rectangle. I

问题 I have a GUI application (made with PyQt5 and QML) and would like to get notify when a usb device is plugged or unplugged from the computer. After some investigation, I have found that pyudev could be the library to use. But I have trouble using it with PyQt5 and QML. I have succeed to use the pyudev example for MonitorObservor, and there are other example provided in the documentation, here with PySide and here with Glib. I have also found an example using PyQt5 and widgets application here.

问题 We are converting some older QT widget code to use QML and I cannot find the equivalent property for the QFont::setStretch() operation. The QML Font page shows only family, bold, italic, underline, pointSize, pixelSize, weight, overline, strikeout, capitalization, letterSpacing, wordSpacing, kerning, preferShaping and hintingPreference. This font selection is being done within a Text object, along the lines of: Text { font.family: "LiberationSans" font.pixelSize: 178 font.weight: 80 //font

问题 How can I include the QML file into my Python project as a single executable. When I run pyinstaller --onefile main.py , running the executable results in an error that the QML file is not found. Unless I use an absolute path or place view.qml in the same directory as my executable. I don't want to have a separate QML file, I want it combined into the executable. main.py: if __name__ == "__main__": app = QGuiApplication(sys.argv) engine = QQmlApplicationEngine() engine.load(QUrl("view.qml"))

问题 I've included to my project : "import QtQuickQontrols 1.4" But now I need to use ScrollBar , and for this, I need to include "import QtQuickControls 2.2" But when I include version 2.2 and delete 1.4, my project is ruined... MenuBar, TableView is under errors! Ok, when I include both this version it's errors , too! I did run qmake, and give me some advice what should I do to implement my ScrollBar. I've tried to add ScrollView, but inside this it doesn't work : .... ScrollBar.vertical:

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 have two custom QML elements for audio, one for playing music (and extends the QML Audio element) and one for playing sound effects (which extends QML's SoundEffect element). I am able to play background music with no problem, but when I try to play a sound effect, the interface freezes for a couple of seconds (the music keeps playing) and then when it unfreezes, I get the Windows error sound. Here is what I have (the music has a similar architecture): MySoundEffect.qml Loader { id:
