<div class="descr">
<h2>Detailed Description</h2>
<p>The QDesignerFormWindowCursorInterface class allows you to query and modify a form window's widget selection, and in addition modify the properties of all the form's widgets.</p>
<p>QDesignerFormWindowCursorInterface is a convenience class that provides an interface to the associated form window's text cursor; it provides a collection of functions that enables you to query a given form window's selection and change the selection's focus according to defined modes (<a href="qdesignerformwindowcursorinterface.html#MoveMode-enum">MoveMode</a>) and movements (<a href="qdesignerformwindowcursorinterface.html#MoveOperation-enum">MoveOperation</a>). You can also use the interface to query the form's widgets and change their properties.</p>
<p>The interface is not intended to be instantiated directly, but to provide access to the selections and widgets of <i>Qt Designer</i>'s current form windows. <a href="qdesignerformwindowinterface.html">QDesignerFormWindowInterface</a> always provides an associated cursor interface. The form window for a given widget can be retrieved using the static <a href="qdesignerformwindowinterface.html#findFormWindow">QDesignerFormWindowInterface::findFormWindow</a>() functions. For example:</p>
<pre class="cpp"> <span class="type"><a href="qdesignerformwindowinterface.html">QDesignerFormWindowInterface</a></span> <span class="operator">*</span>formWindow <span class="operator">=</span> <span class="number">0</span>;
formWindow <span class="operator">=</span> <span class="type"><a href="qdesignerformwindowinterface.html">QDesignerFormWindowInterface</a></span><span class="operator">::</span>findFormWindow(myWidget);
formWindow<span class="operator">-</span><span class="operator">></span>cursor()<span class="operator">-</span><span class="operator">></span><a href="qdesignerformwindowcursorinterface.html#setProperty">setProperty</a>(myWidget<span class="operator">,</span> myProperty<span class="operator">,</span> newValue);</pre>
<p>You can retrieve any of <i>Qt Designer</i>'s current form windows through <i>Qt Designer</i>'s <a href="qdesignerformwindowmanagerinterface.html">form window manager</a>.</p>
<p>Once you have a form window's cursor interface, you can check if the form window has a selection at all using the <a href="qdesignerformwindowcursorinterface.html#hasSelection">hasSelection</a>() function. You can query the form window for its total <a href="qdesignerformwindowcursorinterface.html#widgetCount">widgetCount</a>() and <a href="qdesignerformwindowcursorinterface.html#selectedWidgetCount">selectedWidgetCount</a>(). You can retrieve the currently selected widget (or widgets) using the <a href="qdesignerformwindowcursorinterface.html#current">current</a>() or <a href="qdesignerformwindowcursorinterface.html#selectedWidget">selectedWidget</a>() functions.</p>
<p>You can retrieve any of the form window's widgets using the <a href="qdesignerformwindowcursorinterface.html#widget">widget</a>() function, and check if a widget is selected using the <a href="qdesignerformwindowcursorinterface.html#isWidgetSelected">isWidgetSelected</a>() function. You can use the <a href="qdesignerformwindowcursorinterface.html#setProperty">setProperty</a>() function to set the selected widget's properties, and the <a href="qdesignerformwindowcursorinterface.html#setWidgetProperty">setWidgetProperty</a>() or <a href="qdesignerformwindowcursorinterface.html#resetWidgetProperty">resetWidgetProperty</a>() functions to modify the properties of any given widget.</p>
<p>Finally, you can change the selection by changing the text cursor's <a href="qdesignerformwindowcursorinterface.html#position">position</a>() using the <a href="qdesignerformwindowcursorinterface.html#setPosition">setPosition</a>() and <a href="qdesignerformwindowcursorinterface.html#movePosition">movePosition</a>() functions.</p>
