    \class QDesignerPropertyEditorInterface

    \brief The QDesignerPropertyEditorInterface class allows you to

    query and manipulate the current state of Qt Designer's property

    editor.

    \inmodule QtDesigner

    QDesignerPropertyEditorInterface contains a collection of

    functions that is typically used to query the property editor for

    its current state, and several slots manipulating it's state. The

    interface also provide a signal, propertyChanged(), which is

    emitted whenever a property changes in the property editor. The

    signal's arguments are the property that changed and its new

    value.

    For example, when implementing a custom widget plugin, you can

    connect the signal to a custom slot:

    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractpropertyeditor.cpp 0

    Then the custom slot can check if the new value is within the

    range we want when a specified property, belonging to a particular

    widget, changes:

    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractpropertyeditor.cpp 1

    The QDesignerPropertyEditorInterface class is not intended to be

    instantiated directly. You can retrieve an interface to \QD's

    property editor using the

    QDesignerFormEditorInterface::propertyEditor() function. A pointer

    to \QD's current QDesignerFormEditorInterface object (\c

    formEditor in the examples above) is provided by the

    QDesignerCustomWidgetInterface::initialize() function's

    parameter. When implementing a custom widget plugin, you must

    subclass the QDesignerCustomWidgetInterface to expose your plugin

    to \QD.

    The functions accessing the property editor are the core()

    function that you can use to retrieve an interface to the form

    editor, the currentPropertyName() function that returns the name

    of the currently selected property in the property editor, the

    object() function that returns the currently selected object in

    \QD's workspace, and the isReadOnly() function that returns true

    if the property editor is write proteced (otherwise false).

    The slots manipulating the property editor's state are the

    setObject() slot that you can use to change the currently selected

    object in \QD's workspace, the setPropertyValue() slot that

    changes the value of a given property and the setReadOnly() slot

    that control the write protection of the property editor.
