<h2>Detailed Description</h2>
<p>The QDesignerPropertyEditorInterface class allows you to query and manipulate the current state of Qt Designer's property editor.</p>
<p>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, <a href="qdesignerpropertyeditorinterface.html#propertyChanged">propertyChanged</a>(), which is emitted whenever a property changes in the property editor. The signal's arguments are the property that changed and its new value.</p>
<p>For example, when implementing a custom widget plugin, you can connect the signal to a custom slot:</p>
<pre> QDesignerPropertyEditorInterface *propertyEditor = 0;
propertyEditor = formEditor->propertyEditor();
connect(propertyEditor, SIGNAL(propertyChanged(QString, QVariant)),
this, SLOT(checkProperty(QString, QVariant)));</pre>
<p>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:</p>
<pre> void checkProperty(QString property, QVariant value) {
QDesignerPropertyEditorInterface *propertyEditor = 0;
propertyEditor = formEditor->propertyEditor();
QObject *object = propertyeditor->object();
MyCustomWidget *widget = qobject_cast<MyCustomWidget>(object);
if (widget && property == aProperty && value != expectedValue)
{...}
}</pre>
<p>The QDesignerPropertyEditorInterface class is not intended to be instantiated directly. You can retrieve an interface to <i>Qt Designer</i>'s property editor using the <a href="qdesignerformeditorinterface.html#propertyEditor">QDesignerFormEditorInterface::propertyEditor</a>() function. A pointer to <i>Qt Designer</i>'s current <a href="qdesignerformeditorinterface.html">QDesignerFormEditorInterface</a> object (<tt>formEditor</tt> in the examples above) is provided by the <a href="qdesignercustomwidgetinterface.html#initialize">QDesignerCustomWidgetInterface::initialize</a>() function's parameter. When implementing a custom widget plugin, you must subclass the <a href="qdesignercustomwidgetinterface.html">QDesignerCustomWidgetInterface</a> to expose your plugin to <i>Qt Designer</i>.</p>
<p>The functions accessing the property editor are the <a href="qdesignerpropertyeditorinterface.html#core">core</a>() function that you can use to retrieve an interface to the form editor, the <a href="qdesignerpropertyeditorinterface.html#currentPropertyName">currentPropertyName</a>() function that returns the name of the currently selected property in the property editor, the <a href="qdesignerpropertyeditorinterface.html#object">object</a>() function that returns the currently selected object in <i>Qt Designer</i>'s workspace, and the <a href="qdesignerpropertyeditorinterface.html#isReadOnly">isReadOnly</a>() function that returns true if the property editor is write proteced (otherwise false).</p>
<p>The slots manipulating the property editor's state are the <a href="qdesignerpropertyeditorinterface.html#setObject">setObject</a>() slot that you can use to change the currently selected object in <i>Qt Designer</i>'s workspace, the <a href="qdesignerpropertyeditorinterface.html#setPropertyValue">setPropertyValue</a>() slot that changes the value of a given property and the <a href="qdesignerpropertyeditorinterface.html#setReadOnly">setReadOnly</a>() slot that control the write protection of the property editor.</p>
