The UI forms contain a purely declarative subset of the QML language. It is recommended that you edit the forms in the \uicontrol Design mode. \QC enforces the use of the supported QML features by displaying error messages. The following features are not supported: \list \li JavaScript blocks \li Other bindings than pure expressions \li Signal handlers \li States in other items than the root item \li Root items that are not derived from \l QQuickItem or \l [QML]{Item} \endlist The following types are not supported: \list \li Behavior \li Binding \li Canvas \li Component \li Shader Effect \li Timer \li Transform \li Transition \endlist \section1 Supported Methods \QC supports most JavaScript functions that are supported by the QML engine, as well as a subset of Qt QML methods. This section lists the functions that you can use in \e .ui.qml files. \section2 JavaScript Functions As a rule of thumb, \e {pure functions} are supported. They only depend on and modify states of parameters that are within their scope, and therefore always return the same results when given the same parameters. This makes it possible to convert and reformat property bindings without breaking the \e .ui.qml files. The following JavaScript functions are supported: \list \li \c charAt() \li \c charCodeAt() \li \c concat() \li \c endsWith() \li \c includes() \li \c indexOf() \li \c isFinite() \li \c isNaN() \li \c lastIndexOf() \li \c substring() \li \c toExponential() \li \c toFixed() \li \c toLocaleLowerCase() \li \c toLocaleString \li \c toLocaleUpperCase() \li \c toLowerCase() \li \c toPrecision() \li \c toString() \li \c toUpperCase() \li \c valueOf() \endlist In addition, all functions of the \c Math and \c Date objects are supported. For more information, see \l{https://doc.qt.io/qt-5/qtqml-javascript-functionlist.html} {List of JavaScript Objects and Functions}. \section2 Qt QML Methods \QC supports color methods, helper methods for creating objects of specific data types, and translation methods. The following color methods are supported: \list \li \l{Qt::darker()}{Qt.darker()} \li \l{Qt::hsla()}{Qt.hsla()} \li \l{Qt::hsva()}{Qt.hsva()} \li \l{Qt::lighter()}{Qt.lighter()} \li \l{Qt::rgba()}{Qt.rgba()} \li \l{Qt::tint()}{Qt.tint()} \endlist The following helper methods are supported: \list \li \l{Qt::formatDate()}{Qt.formatDate()} \li \l{Qt::formatDateTime()}{Qt.formatDateTime()} \li \l{Qt::formatTime()}{Qt.formatTime()} \li \l{Qt::matrix4x4()}{Qt.matrix4x4()} \li \l{Qt::point()}{Qt.point()} \li \l{Qt::quaternion()}{Qt.quaternion()} \li \l{Qt::rect()}{Qt.rect()} \li \l{Qt::size()}{Qt.size()} \li \l{Qt::vector2d()}{Qt.vector2d()} \li \l{Qt::vector3d()}{Qt.vector3d()} \li \l{Qt::vector4d()}{Qt.vector4d()} \endlist The following translation methods are supported: \list \li \l{Qt::}{qsTr()} \li \l{Qt::}{qsTranslate()} \li \l{Qt::}{qsTranslateNoOp()} \li \l{Qt::}{qsTrId()} \li \l{Qt::}{qsTrIdNoOp()} \li \l{Qt::}{qsTrNoOp()} \endlist For more information about using the methods, see \l{https://doc.qt.io/qt-5/qml-qtqml-qt.html}{Qt QML Methods}. \section1 Using Qt Quick UI Forms You can edit the forms in the \uicontrol {Form Editor} and \uicontrol {Text Editor} tabs in the \uicontrol Design mode. Items that are supposed to be used in QML code have to be exported as properties: \code Item { width: 640 height: 480 property alias button: button Button { anchors.centerIn: parent id: button text: qsTr("Press Me") } } \endcode The property alias exports the button to the QML code that uses the form. You can use the \inlineimage export_checked.png (\uicontrol Export) button in the \uicontrol Navigator to export an item as a property: \image qmldesigner-export-item.png In the QML file that uses the form, you can use the \c button property alias to implement signal handlers, for example. In the following code snippet, the UI form is called \e MainForm.ui.qml: \code MainForm { anchors.fill: parent button.onClicked: messageDialog.show(qsTr("Button pressed")) } \endcode You can also assign properties or define behavior or transitions. To move from the \uicontrol Design mode directly to the implementation of a type in the .qml file, right-click the type in the \uicontrol Navigator and select \uicontrol {Go to Implementation} in the context menu. */
