For example: - -\qml -Rectangle { - width: 200; height: 200 - MouseArea { - anchors.fill: parent - onClicked: console.log("clicked") - } -} -\endqml - -\section1 Debugging Transitions - -When a transition doesn't look quite right, it can be helpful to view it in slow -motion to see what is happening more clearly. This functionality is supported -in the \l {QML Viewer} tool: to enable this, -click on the "Debugging" menu, then "Slow Down Animations". - - -\section1 Debugging module imports - -The \c QML_IMPORT_TRACE environment variable can be set to enable debug output -from QML's import loading mechanisms. - -For example, for a simple QML file like this: - -\qml -import QtQuick 1.0 - -Rectangle { width: 100; height: 100 } -\endqml - -If you set \c {QML_IMPORT_TRACE=1} before running the \l {QML Viewer} -(or your QML C++ application), you will see output similar to this: - -\code -QDeclarativeImportDatabase::addImportPath "/qt-sdk/imports" -QDeclarativeImportDatabase::addImportPath "/qt-sdk/bin/QMLViewer.app/Contents/MacOS" -QDeclarativeImportDatabase::addToImport 0x106237370 "." -1.-1 File as "" -QDeclarativeImportDatabase::addToImport 0x106237370 "Qt" 4.7 Library as "" -QDeclarativeImportDatabase::resolveType "Rectangle" = "QDeclarativeRectangle" -\endcode - - -\section1 Debugging with Qt Creator - -\l{http://qt.nokia.com/products/developer-tools}{Qt Creator} provides built-in -support for QML debugging.
