It is not included in the main TQt API. <p> The TQXtWidget class allows mixing of Xt/Motif and TQt widgets. <b>This class is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code. <p> <p> TQXtWidget acts as a bridge between Xt and TQt. For utilizing old Xt widgets, it can be a <a href="ntqwidget.html">TQWidget</a> based on a Xt widget class. For including TQt widgets in an existing Xt/Motif application, it can be a special Xt widget class that is a TQWidget. See the constructors for the different behaviors. <p> <h4> Known TQXtWidget Problems </h4> <a name="1"></a><p> This class is unsupported and has many known problems and limitations. It is provided only to keep existing source working; it should not be used in new code. Note: These problems will <em>not</em> be fixed in future releases. <p> Below is an imcomplete list of know issues: <p> <ol type=1> <p> <li> <a href="focus.html#keyboard-focus">Keyboard focus</a> navigation is impossible when using TQXtWidget. The mouse must be used to focus widgets in both TQt and Xt/Motif widgets. For example, when embedding a TQXtWidget into an Xt/Motif widget, key events will go to the TQXtWidget (and its children) while the mouse is over the TQXtWidget, regardless of where Xt/Motif has placed the focus. <p> <li> Reparenting does not work. You cannot use <a href="ntqwidget.html#reparent">TQWidget::reparent</a>(). This includes the functions <a href="ntqwidget.html#showFullScreen">TQWidget::showFullScreen</a>() and <a href="ntqwidget.html#showNormal">TQWidget::showNormal</a>(), which use TQWidget::reparent(). <p> </ol> <hr><h2>Member Function Documentation</h2> <h3 class=fn><a name="TQXtWidget"></a>TQXtWidget::TQXtWidget ( const char * name, Widget parent, bool managed = FALSE ) </h3> Constructs a TQXtWidget of the special Xt widget class known as "TQWidget" to the resource manager. <p> Use this constructor to utilize TQt widgets in an Xt/Motif application. The TQXtWidget is a <a href="ntqwidget.html">TQWidget</a>, so you can create subwidgets, layouts, etc. using TQt functionality. <p> The <em>name</em> is the object name passed to the TQWidget constructor. The widget's parent is <em>parent</em>. <p> If the <em>managed</em> parameter is TRUE and <em>parent</em> in not null, XtManageChild it used to manage the child. <h3 class=fn><a name="TQXtWidget-2"></a>TQXtWidget::TQXtWidget ( const char * name, WidgetClass widget_class, <a href="ntqwidget.html">TQWidget</a> * parent = 0, ArgList args = 0, Cardinal num_args = 0, bool managed = FALSE ) </h3> Constructs a TQXtWidget of the given <em>widget_class</em> called <em>name</em>. <p> Use this constructor to utilize Xt or <a href="motif-extension.html#Motif">Motif</a> widgets in a TQt application. The TQXtWidget looks and behaves like the Xt class, but can be used like any <a href="ntqwidget.html">TQWidget</a>. <p> Note that Xt requires that the most top level Xt widget is a shell. This means, if <em>parent</em> is a TQXtWidget, the <em>widget_class</em> can be of any kind. If there isn't a parent or the parent is just a normal TQWidget, <em>widget_class</em> should be something like <tt>topLevelShellWidgetClass</tt>. <p> The arguments, <em>args</em>, <em>num_args</em> are passed on to XtCreateWidget. <p> If the <em>managed</em> parameter is TRUE and <em>parent</em> in not null, XtManageChild it used to manage the child. <h3 class=fn><a name="~TQXtWidget"></a>TQXtWidget::~TQXtWidget () </h3> Destructs the TQXtWidget. <h3 class=fn>bool <a name="isActiveWindow"></a>TQXtWidget::isActiveWindow () const </h3> Different from <a href="ntqwidget.html#isActiveWindow">TQWidget::isActiveWindow</a>() <h3 class=fn>void <a name="setActiveWindow"></a>TQXtWidget::setActiveWindow ()<tt> [virtual]</tt> </h3> Implement a degree of focus handling for Xt widgets. <p>Reimplemented from <a href="ntqwidget.html#setActiveWindow">TQWidget</a>. <h3 class=fn>bool <a name="x11Event"></a>TQXtWidget::x11Event ( XEvent * e )<tt> [virtual protected]</tt> </h3> Reimplemented to produce the Xt effect of getting focus when the mouse enters the widget. The event is passed in <em>e</em>. <p>Reimplemented from <a href="ntqwidget.html#x11Event">TQWidget</a>. <h3 class=fn>Widget <a name="xtWidget"></a>TQXtWidget::xtWidget () const </h3> <p> Returns the Xt widget equivalent for the TQt widget. <!-- eof --> <hr><p> This file is part of the <a href="index.html">TQt toolkit</a>.
