You call setData implicitly by setting the variable (called like the role name) in the delegate:. I'm guessing that the C++ version of QTableView must provide this missing piece, but if you define you're TableView in QML, you will have to do this for your C++ model before passing it to QML. { Q_OBJECT Q_ENUMS(Roles) public: enum Roles Therefore we should provide a string-to-int mapping for each role so the QML can correctly asking for the required data. Note that if there is a validator or inputMask set on the text TableView { TableViewColumn { role: "title"; title: "Title"; width: 100 } TableViewColumn { role: "author"; title: "Author"; width: 200 } model: libraryModel } The only hack I can think of is to assign each column in my model a unique role name, but this seems like a code smell, is there another simple way to specify the column index of my TableViewColumn ? I've got a delegate attached to my TableViewColumn that contains a MouseArea. qml file is: import QtQuick 2. To create models with multiple columns, either use TableModel or a C++ model that inherits QAbstractItemModel .

All the documenation and examples I've read override QAbstractItemModel::roleNames() to expose model data associated with the roles as properties in QML. I am not sure why flickableItem. Since you need different delegates for different columns it can be done in a bit "tricky" way with Loader. These choices are used to determine the delegate So according to your code example, you want the handle to be red, and the frame around the view to be white, right? Then what you do is put what you have on the ScrollViewStyle on your TableViewStyle, like this, because as previously explained in both topics you started, TableView inherits from ScrollView, so the properties from the parent class can be used in the Ordinarily, the predefined roles like display or edit are enough. class MySqlModel: public QSqlQueryModel { Q_OBJECT public: MySqlModel If you want to add a QML control into a cell you just have to define custom delegate.

TableView { model: fileSystemModel TableViewColumn { role: "display" } } That said, if you define custom roles, you have to override that roleNames() method, to give names As model manipulation in Qt is done via row and column indices, and because object keys are unordered, each column must be specified via TableModelColumn. 1 import QtQuick. As you suggested I add two method but still I don't get 'Some data' message in each cell.

Neither do you need to have custom QQuickItem classes. TableView: A component for displaying tabular data in QML/Qt. But I came to know from Qt documentation that I must implement roleNames() to supply column to role mapping to TableView, so I subclassed While trying to display data from QSQLITE table in QML TableView I stumbled upon this answer and tried to follow up with it. DelegateChooser encapsulates a set of DelegateChoices. open() TableViewColumn { id: orderNumberColumn role: "orderNumber" title: "Order Number" } model : openordersModel } ListModel { id QML TableView get row clicked with QtQuick If you suspect the C++ model is causing the issue, then try with a QML TableModel and see if that indeed makes it disappear. So, a read-only model which uses the predefined display role (Qt::DisplayRole in C++) can be used like this in QML: TableView { // delegate: Label { text: display } } In this setup, QML will call data with Qt::DisplayRole argument for you. The UI looks like this: After pressing the "Update List Model" a new row should appear in the TableView. 11) . The problem is the delegate MouseArea blocks mouse events from propagating through to TableView. QHeaderView uses Qt::SizeHintRole to calculate its recommended width if it is horizontal and height if it is vertical. A white space should be shown instead. item With onAccepted handler, changes are saved only when the Enter key is pressed. However, I've found out that there also exists QAbstractTableModel, which allows using This method returns a set of mappings between the role on the C++ side and the role name, as a string literal, we need to use on the QML side. TableModelColumn supports all of Qt's roles, with the exception of Qt::InitialSortOrderRole. selected = !model. in my Qt . interactive: false is not working, (may be its an issue/bug with old TableView {}, Just a guess). 15 I can create a TableView and HorizontalHeaderView and display the table without hard coding the column names. 1.

I have tried on HeaderDelegate create a MouseArea with width, height TableViewColumn { title: "column1" role: "column1" } TableViewColumn { title: "column2" role: "column2" } headerDelegate: Rectangle { height : tViewEnt. role. I can't get timeToReply in rowDelegate. 4 TableViewColumn { title: "" role: "check" delegate: CheckBox { anchors. implicitHeight Text { id: header text: &quot;A table header&quot; } model: myModel } a Is there a simple way to modify a row height given its index in a QML TableView ? My problem is that I dynamically load data is the TableView's "" status"" } } TableView { id: filesTable TableViewColumn { id:nameColumn role: "name" title: "Name" width: dropFiles. log(model. Assign role names to QAbstractItemModel now that setRolesNames() method is deprecated. After looking at the sorting that is done in C++, I realized that TableView only has 1 column, so it is using properties, aka roles and names, to map the attributes to columns, but it seems I could use the delegate to try to expose a click event, but to do a sort would be more complex than doing a model refresh with query, TableView QML Type Provides a list view with scroll bars, styling and header sections. pro file, I added: !android: !ios: ! and my . Improve this question. role - the role of the view column; styleData. g. I am missing some important and obvious about how the role concept works with Qt QML TableView's. QtQuick TableView not working with C++-QAbstractTableModel. text: display required property string display. This information is represented by the CellRole value of the Reusing items. A simple example: add a "selected" flag to your model entries and then toggle it via interaction - each delegate could contain a MouseArea that, when clicked, will do something like model. But I don't know what to do more to make it sorted when user clicked on header. The Conway’s Game of Life example shows how the QML TableView type can be used to display a C++ model that the user can pan around. In this case, if we use columnCount has no effect, as long is it is > 0, because TableView called the index method with column always equal to 0. It reimplements QAbstractItemModel::roleNames() to expose the role names, so that they can be accessed via QML TableView access model properties from delegate. I'm creating a QML TableView and I want the text (in both the rows AND headers) to middle-ellipse whenever the text is too long to fit into its column. A TableView displays data from models created from built-in QML types such as ListModel and XmlListModel, which populates the first column only in a TableView. push(columnComponent. The delegate of the column. This means that the selection behaviour of Pass QStandardItemModel from C++ to QtQuick / QML TableView and display it. qml TableViewColumn { title: "" role: "check" I'm trying to display a QStandardItemModel subclass with the Qt Controls TableView in QML. 4: Since: Qt 5. I have a TableView that I want to fill dynamically after it is created - i. 4. The data method must provide the information required I am trying to display Image and Text in a row of QML table live_alertmodel } TableView { // anchors. selected. For QML TableView, you also need to reimplement data() and return values as per the roles in it. horizontalCenter } } } You have to subclass QSqlQueryModel and reimplement roleNames and data methods. The application is composed from the following parts: A data model: it stores the data and it is used by a TableView as a I use TableView for my application in Qt5. There is another way: . How to observe the fields of the table are not roles, so they can not be accessed from QML, QT SqlQueryModel TableView to ListView. TableView recycles delegate items by default, instead of instantiating from the delegate whenever new rows and columns are flicked into view. For example: This_is_really_long_text might display as Thistext I want to implement a sortable TableView with custom roles with Qt 5. I think there must be something wrong about the roles/fieldnames but I can't find out whats wrong. "Selection" is an arbitrary concept, so how something becomes selected would be up to you. channel) I alwasy get undefined. Modified 6 years, 8 months ago. The missing part of the equation seems to be that it is not possible to have a variable number of columns in the TableView, I want to show QSqlQueryModel in qml TableView but I don't Wan't to create separate QML file for each new query cause I can't create infinite qml files as given here. 12: Inherits: This includes index, row, and column, but also any model roles. The DelegateChooser is a special Component type intended for those scenarios where a Component is required by a view and used as a delegate. I want a TableView to fill the width of the parent item, but it will not resize the columns unless I drag the table. The following version of the method checks if the given model index is valid and the role is equal to Qt::EditRole, before executing the actual update. Resolve Integer-Role to RoleName in QML. When the array is modified, forceLayout is called to let the changes take effect: TableView { id: tableView property var columnWidths: [100, 50, 80, 150] columnWidthProvider: function (column) { return columnWidths [column] } Timer { running: true I have a tableview and I want to open a dialog box on onPressAndHold on a row and display visible: true onPressAndHold: oocanceldialog. So you can add custom role names and forward those header roles to the Hi @CoderJeff, Assuming you are using QAbstractTableModel or QAbstractItemModel as C++ model with QML, to update the view, use setData to update the model and then fire the dataChanged signal with appropriate index to notify the view about the changes. 3. Any hints? 2. So '2' defines Qt::EditRole. On the other hand, as of >= Qt5. I want to display a subset of columns from an large existing C++ TableModel in a new QML TableView. Stack Overflow.
