<p> This class is defined in the <b>TQt <a href="motif-extension.html#Motif">Motif</a> Extension</b>, which can be found in the <tt>qt/extensions</tt> directory. 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This class is obsolete.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="qwidget.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="qwidget.html#reparent">TQWidget::reparent</a>(). This includes the functions
<a href="qwidget.html#showFullScreen">TQWidget::showFullScreen</a>() and <a href="qwidget.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&nbsp;char&nbsp;*&nbsp;name, Widget&nbsp;parent, bool&nbsp;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="qwidget.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&nbsp;char&nbsp;*&nbsp;name, WidgetClass&nbsp;widget_class, <a href="qwidget.html">TQWidget</a>&nbsp;*&nbsp;parent = 0, ArgList&nbsp;args = 0, Cardinal&nbsp;num_args = 0, bool&nbsp;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="qwidget.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="qwidget.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="qwidget.html#setActiveWindow">TQWidget</a>.
<h3 class=fn>bool <a name="x11Event"></a>TQXtWidget::x11Event ( XEvent&nbsp;*&nbsp;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="qwidget.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.
