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> QDesignerFormWindowInterface *formWindow = 0; formWindow = QDesignerFormWindowInterface::findFormWindow(myWidget); formWindow->cursor()->setProperty(myWidget, myProperty, 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> <p>See also <a href="qdesignerformwindowinterface.html">QDesignerFormWindowInterface</a> and <a href="qdesignerformwindowmanagerinterface.html">QDesignerFormWindowManagerInterface</a>.</p> <hr /> <h2>Member Type Documentation</h2> <h3 class="fn"><a name="MoveMode-enum"></a>enum QDesignerFormWindowCursorInterface::MoveMode</h3> <p>This enum describes the different modes that are used when the text cursor moves.</p> <p><table border="1" cellpadding="2" cellspacing="1" width="100%"> <tr><th width="25%">Constant</th><th width="15%">Value</th><th width="60%">Description</th></tr> <tr><td valign="top"><tt>QDesignerFormWindowCursorInterface::MoveAnchor</tt></td><td align="center" valign="top"><tt>0</tt></td><td valign="top">The anchor moves with the cursor to its new location.</td></tr> <tr><td valign="top"><tt>QDesignerFormWindowCursorInterface::KeepAnchor</tt></td><td align="center" valign="top"><tt>1</tt></td><td valign="top">The anchor remains at the cursor's old location.</td></tr> </table></p> <h3 class="fn"><a name="MoveOperation-enum"></a>enum QDesignerFormWindowCursorInterface::MoveOperation</h3> <p>This enum describes the types of text cursor operation that can occur in a form window.</p> <p><table border="1" cellpadding="2" cellspacing="1" width="100%"> <tr><th width="25%">Constant</th><th width="15%">Value</th><th width="60%">Description</th></tr> <tr><td valign="top"><tt>QDesignerFormWindowCursorInterface::NoMove</tt></td><td align="center" valign="top"><tt>0</tt></td><td valign="top">The cursor does not move.</td></tr> <tr><td valign="top"><tt>QDesignerFormWindowCursorInterface::Start</tt></td><td align="center" valign="top"><tt>1</tt></td><td valign="top">Moves the cursor to the start of the focus chain.</td></tr> <tr><td valign="top"><tt>QDesignerFormWindowCursorInterface::End</tt></td><td align="center" valign="top"><tt>2</tt></td><td valign="top">Moves the cursor to the end of the focus chain.</td></tr> <tr><td valign="top"><tt>QDesignerFormWindowCursorInterface::Next</tt></td><td align="center" valign="top"><tt>3</tt></td><td valign="top">Moves the cursor to the next widget in the focus chain.</td></tr> <tr><td valign="top"><tt>QDesignerFormWindowCursorInterface::Prev</tt></td><td align="center" valign="top"><tt>4</tt></td><td valign="top">Moves the cursor to the previous widget in the focus chain.</td></tr> <tr><td valign="top"><tt>QDesignerFormWindowCursorInterface::Left</tt></td><td align="center" valign="top"><tt>5</tt></td><td valign="top">The cursor moves to the left.</td></tr> <tr><td valign="top"><tt>QDesignerFormWindowCursorInterface::Right</tt></td><td align="center" valign="top"><tt>6</tt></td><td valign="top">The cursor moves to the right.</td></tr> <tr><td valign="top"><tt>QDesignerFormWindowCursorInterface::Up</tt></td><td align="center" valign="top"><tt>7</tt></td><td valign="top">The cursor moves upwards.</td></tr> <tr><td valign="top"><tt>QDesignerFormWindowCursorInterface::Down</tt></td><td align="center" valign="top"><tt>8</tt></td><td valign="top">The cursor moves downwards.</td></tr> </table></p> <hr /> <h2>Member Function Documentation</h2> <h3 class="fn"><a name="dtor.QDesignerFormWindowCursorInterface"></a>QDesignerFormWindowCursorInterface::~QDesignerFormWindowCursorInterface () <tt> [virtual]</tt></h3> <p>Destroys the cursor interface.</p> <h3 class="fn"><a name="current"></a><a href="qwidget.html">QWidget</a> * QDesignerFormWindowCursorInterface::current () const <tt> [pure virtual]</tt></h3> <p>Returns the currently selected widget in the form window.</p> <p>See also <a href="qdesignerformwindowcursorinterface.html#selectedWidget">selectedWidget</a>().</p> <h3 class="fn"><a name="formWindow"></a><a href="qdesignerformwindowinterface.html">QDesignerFormWindowInterface</a> * QDesignerFormWindowCursorInterface::formWindow () const <tt> [pure virtual]</tt></h3> <p>Returns the form window interface associated with this cursor interface.</p> <h3 class="fn"><a name="hasSelection"></a>bool QDesignerFormWindowCursorInterface::hasSelection () const <tt> [pure virtual]</tt></h3> <p>Returns true if the form window contains a selection;
