问题 I Started new project with Qt5 , and tried Qt Quick Project( QML ) on Windows10(64bit). Because I want to use various animations & effects. But I hit a brick wall, that I can't run & debug QML projects. First, I want to use swiping so I try swipe example, but the project makes an error. The run error is first image, and the debug error is second image. p.s - I tried somthing to solve the errors, which are updating NVIDIA driver, trying to release mode and making a new Qt Quick Application

问题 I am currently working with Qt 5.2.1... and I have a (maybe stupid?) question: What is the difference between QQuickView and QQuickWindow ? I read the documentation but it is still not clear to me... 回答1: From the Qt documentation: The QQuickView class provides a window for displaying a Qt Quick user interface. QQuickView is a convenience subclass of QQuickWindow which will automatically load and display a QML scene when given the URL of the main source file. So QQuickView is a subclass of

问题 I am new to Qt Designer Studio. I just created a simple button in Qt Design Studio and I am trying to use the QML file with PySide2 but I am getting multiple import errors. Is there a specific way to implement Qt Design Studio qml files with PySide2. The project name is Demo that I created in Qt Design Studio The Demo Project structure: Demo.qml Demo.qmlproject Demo.qmlproject.qtds imports qtquickcontrols2.conf Screen01.ui.qml The PySide2 project structure (main.py files includes the code):

问题 I have a combobox in qml in a as a TableViewColummn and I define it as follows: import QtQuick 2.3 import QtQuick.Window 2.2 import QtQuick.Layouts 1.1 import QtQuick.Controls 1.4 import QtQuick.Controls.Styles 1.4 ListModel { id: comboModel ListElement { text: "" Index: -1 Dims: -1 } } TableViewColumn { id: imageTypeList role: "ImageType" title: "Image Type" width: 100 delegate: Rectangle { ComboBox { anchors.verticalCenter: parent.verticalCenter anchors.margins: 2 model: comboModel

问题 The QT document had implied that any implementation of QAbstractItemModel can be used for TreeView. These models are usually in C++, which is inconvenient for now. So is there an native QML model which can be utilized in treeview? Can I set a QStandardItemModel model from C++, and use this model in qml? 回答1: The QStandardItemModel reference gives an example of how to use it for a TreeView: QStandardItemModel model; QStandardItem *parentItem = model.invisibleRootItem(); for (int i = 0; i < 4;

问题 I am using Qt 5.9.3. I have following property declared in my app's main.qml Code: //main.qml MyQuickItem { property color nextColor onNextColorChanged: { console.log("The next color will be: " + nextColor.toString()) } } // MyQuickItem.h class MyQuickItem : public QQuickItem { } Question: How can I make onNextColorChanged be defined in the C++ side? I know that I can also make nextColor as a property inside C++ class MyQuickItem . like so // MyQuickItem.h class MyQuickItem : public
