问题 i am trying to insert/edit a python list that is subclassed from QAbstractListModel in pyqt5. this python list is read in the model property of ListView element in qml. i have no issues displaying the data in qml. problem arises when i try to append new data into the python list. the following is what i have done so far: main.py: import sys, model2 from PyQt5.QtCore import QUrl from PyQt5.QtWidgets import QApplication from PyQt5.QtQuick import QQuickView class MainWindow(QQuickView): def _

问题 My starting point is the following QML source, where GridView is showing ListModel with nice animation of item swaps: import QtQuick 1.1 GridView { id: mainGrid width: 825; height: 400; cellWidth: 165; cellHeight: 95 model: myModel delegate: myButton ListModel { id: myModel function createModel() { for (var i=1; i<=20; i++) { append({"display":i}) } } function listItems() { console.log("LIST OF ITEMS") for (var i=0; i<=19; i++) { console.log("model["+i+"]="+get(i).display) } } function

问题 I'm trying to build an app using pyinstaller, PyQt5 and qml (see files below) using the following command. pyrcc5 pyqt5_qml.qrc > pyqt5_qml_qrc.py pyinstaller -w -F --noupx pyqt5_qml.py (OSX 10.11.1, python 3.5.0, qt 5.5.1, pyinstaller 3.0) The pyqt5_qml.py runs fine (open an "Hello world!" window) but the built app complains about module "QtQuick" version 2.4 is not installed . I guess the module has not been included into the built app but I'm not sure how to tell pyinstaller to do it.

问题 again, well i have a question (and maybe a problem), i make a program with qt and qml in qt5 and qml with qtquick 2.0, and i have a c++ model qlist, and i need modify the list in runtime, i use q QQmlListProperty and show the items in qml, but they are not hide and show in the moment when i add or remove my code is next: class ConceptsList: public QObject{ Q_OBJECT Q_PROPERTY(QQmlListProperty<Concept> concepts READ concepts NOTIFY conceptsChanged) Q_CLASSINFO("DefaultProperty", "concepts")

问题 I've figured out how to bind a model derived from QAbstractListModel to a QML view. But the next thing I tired does not work. If a new Item is added to the model the QML view will not update. Why is that? DataObject.h class DataObject { public: DataObject(const QString &firstName, const QString &lastName): first(firstName), last(lastName) {} QString first; QString last; }; SimpleListModel.h class SimpleListModel : public QAbstractListModel { Q_OBJECT enum /*class*/ Roles { FIRST_NAME = Qt:

问题 I'm trying to create a correct Treeview with Qml Qt 5.5. I succeed to have a Treeview with a global root. But impossible to find how to add child for row item. For the moment I got something like that : TreeView { id:listTree anchors.fill: parent anchors.leftMargin: 1 headerVisible: false backgroundVisible: false selection: ItemSelectionModel { model: myModel } TableViewColumn { role: "name" } itemDelegate: Item { Text { anchors.verticalCenter: parent.verticalCenter color: styleData.textColor
