问题 I am trying to make an app which shows 3 pages at a time. The central page shows 3 rectangles displying sql query results 1-3 , the left page is a link to an image from query result 4, and the right page is also built from the same query and has a different layout. Now I am unable to fit these 3 pages into a listmodel and use pathview to make it look like a paginator, because all 3 pages are incongruent and not really a model, hence giving me error ListElement: cannot contain nested elements.

问题 console.log() does not serialize QML objects. I wonder how to do this? 回答1: I use the this function for this. Is there more simple or right way for this task? 来源： https://stackoverflow.com/questions/11990119/dump-or-serialize-object-in-qml

问题 I have my custom list model where I put data which should be displayed on the QML view. But for some kind of reason the view in QML sometimes is updated normally, sometimes with previous data and sometimes updating is not performed. Here is the function where I fill the model - this function is called from some other thread. void MyScreen::fillListModel() { const QString SEPARATOR = " "; myListModel->resetModel(); for (int i = 0; i < MAX_ROWS; ++i) { QString key = QString::fromUtf16(MyData:

问题 I am using QWT library to plot data. It seems that it is not possible to embed QWidget into QML Quick 2 . So, I decided to create QMainWindow as my main window and create its toolbar and menubar using Quick Controls . How should I embed that qml toolbar and menubar into QMainWindow ? 回答1: You should create QML ApplicationWindow with QML MenuBar and ToolBar main.qml ApplicationWindow { visible: false menuBar: MenuBar { Menu { title: "Edit" MenuItem { text: "Cut" } } } toolBar: ToolBar { Row {

问题 I need to intercept requests made in our WebEngine qml component in our Qt application. I have found documentation on QWebEngineUrlRequestInterceptor which seems to do just this here http://doc.qt.io/qt-5/qwebengineprofile.html#details and here http://doc.qt.io/qt-5/qwebengineurlrequestinterceptor.html#details. However I haven't found any code examples on how to do this in Qt/C++. Any help is appreciated. 回答1: Managed to puzzle it together with the help of this post: https://forum.qt.io/topic

问题 The following piece of code generates a white rectangle containing a red rectangle and a grey rectangle. Every rectangle has an associated MouseArea. The grey rectangle becomes blue when the mouse is clicked inside it. The red rectangle prints a console message when the mouse cursor enters inside it and another message when the released signal is emitted. I would like to: press and hold the mouse button inside the grey rectangle (becoming blue) move the cursor outside the grey/blue rectangle

问题 I've got a delegate attached to my TableViewColumn that contains a MouseArea . I use the MouseArea to detect double clicks on individual cells in the table, which allows me to show a TextField for editing purposes. The problem is the delegate MouseArea blocks mouse events from propagating through to TableView . This means that the selection behaviour of TableView no longer works. Specifically, I have SelectionMode.ExtendedSelection enabled. The MouseArea child item is simple and originally
