QmlDesigner



  • I have my own qml element inherited from QDeclarativeItem and written in C++. It is placed in plugin.
    QmlDesigner can see it. However when I place it on canvas QmlDesigner set it's width and height to 0. How can I tell QmlDesigner to set default width and height?
    In addition to this the element have property named source and I want QmlDesigner display 'three dots' beside it to show dialog 'Open File'. QmlDesigner does it with standart 'Qml Image Element'. I've seen source code of 'Qml Image Element' and I did'n find any special code to do it, including setting width and height.

    I have QtCreator 2.5.2

    And just one more question. Is there way to use QmlDesigner as stand alone app instead as plugin to QtCreator?



  • I've found solution for this question.
    You may control appearance of 'Properties pane' by adding specifics file to your elements in directory '/usr/share/qtcreator/qmldesigner/propertyeditor'.
    You may set default property value by providing plugin to qmldesigner with .metainfo file just like '<QT_CREATOR_SRC_PATH>/src/plugins/qmldesigner/qtquickplugin'.



  • bq. How can I tell QmlDesigner to set default width and height?

    There are two possible solutions.

    Give your custom item a default size in the constructor in C++

    Create a .metainfo file that populates the item library and sets a default size

    Short answer: No
    Qt Quick Designer is integrated into Qt Creator quite heavily.
    A stand alone version would be a huge amount of work.
