|
|---|
| 55 | <p> This class is defined in the <b>Qt <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 Qt API.
|
|---|
| 56 | <p>
|
|---|
| 57 |
|
|---|
| 58 | The QXtWidget class allows mixing of Xt/Motif and Qt widgets.
|
|---|
| 59 | <b>This class is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
|
|---|
| 60 | <p>
|
|---|
| 61 | <p> QXtWidget acts as a bridge between Xt and Qt. For utilizing old Xt
|
|---|
| 62 | widgets, it can be a <a href="qwidget.html">QWidget</a> based on a Xt widget class. For
|
|---|
| 63 | including Qt widgets in an existing Xt/Motif application, it can be
|
|---|
| 64 | a special Xt widget class that is a QWidget. See the constructors
|
|---|
| 65 | for the different behaviors.
|
|---|
| 66 | <p> <h4> Known QXtWidget Problems
|
|---|
| 67 | </h4>
|
|---|
| 68 | <a name="1"></a><p> This class is unsupported and has many known problems and
|
|---|
| 69 | limitations. It is provided only to keep existing source working;
|
|---|
| 70 | it should not be used in new code. Note: These problems will <em>not</em>
|
|---|
| 71 | be fixed in future releases.
|
|---|
| 72 | <p> Below is an imcomplete list of know issues:
|
|---|
| 73 | <p> <ol type=1>
|
|---|
| 74 | <p> <li> <a href="focus.html#keyboard-focus">Keyboard focus</a> navigation is impossible when using QXtWidget.
|
|---|
| 75 | The mouse must be used to focus widgets in both Qt and Xt/Motif
|
|---|
| 76 | widgets. For example, when embedding a QXtWidget into an Xt/Motif
|
|---|
| 77 | widget, key events will go to the QXtWidget (and its children) while
|
|---|
| 78 | the mouse is over the QXtWidget, regardless of where Xt/Motif has
|
|---|
| 79 | placed the focus.
|
|---|
| 80 | <p> <li> Reparenting does not work. You cannot use
|
|---|
| 81 | <a href="qwidget.html#reparent">QWidget::reparent</a>(). This includes the functions
|
|---|
| 82 | <a href="qwidget.html#showFullScreen">QWidget::showFullScreen</a>() and <a href="qwidget.html#showNormal">QWidget::showNormal</a>(), which use
|
|---|
| 83 | QWidget::reparent().
|
|---|
| 84 | <p> </ol>

| 87 | <h3 class=fn><a name="QXtWidget"></a>QXtWidget::QXtWidget ( const char * name, Widget parent, bool managed = FALSE )
|
|---|
| 88 | </h3>
|
|---|
| 89 | Constructs a QXtWidget of the special Xt widget class known as
|
|---|
| 90 | "QWidget" to the resource manager.
|
|---|
| 91 | <p> Use this constructor to utilize Qt widgets in an Xt/Motif
|
|---|
| 92 | application. The QXtWidget is a <a href="qwidget.html">QWidget</a>, so you can create
|
|---|
| 93 | subwidgets, layouts, etc. using Qt functionality.
|
|---|
| 94 | <p> The <em>name</em> is the object name passed to the QWidget constructor.
|
|---|
| 95 | The widget's parent is <em>parent</em>.
|
|---|
| 96 | <p> If the <em>managed</em> parameter is TRUE and <em>parent</em> in not null,
|
|---|
| 97 | XtManageChild it used to manage the child.
|
|---|
| 98 |
|
|---|
| 99 | <h3 class=fn><a name="QXtWidget-2"></a>QXtWidget::QXtWidget ( const char * name, WidgetClass widget_class, <a href="qwidget.html">QWidget</a> * parent = 0, ArgList args = 0, Cardinal num_args = 0, bool managed = FALSE )
|
|---|
| 100 | </h3>
|
|---|
| 101 | Constructs a QXtWidget of the given <em>widget_class</em> called <em>name</em>.
|
|---|
| 102 | <p> Use this constructor to utilize Xt or <a href="motif-extension.html#Motif">Motif</a> widgets in a Qt
|
|---|
| 103 | application. The QXtWidget looks and behaves
|
|---|
| 104 | like the Xt class, but can be used like any <a href="qwidget.html">QWidget</a>.
|
|---|
| 105 | <p> Note that Xt requires that the most top level Xt widget is a shell.
|
|---|
| 106 | This means, if <em>parent</em> is a QXtWidget, the <em>widget_class</em> can be
|
|---|
| 107 | of any kind. If there isn't a parent or the parent is just a normal
|
|---|
| 108 | QWidget, <em>widget_class</em> should be something like <tt>topLevelShellWidgetClass</tt>.
|
|---|
| 109 | <p> The arguments, <em>args</em>, <em>num_args</em> are passed on to XtCreateWidget.
|
|---|
| 110 | <p> If the <em>managed</em> parameter is TRUE and <em>parent</em> in not null,
|
|---|
| 111 | XtManageChild it used to manage the child.

|---|
| 112 |
|
|---|
| 113 | <h3 class=fn><a name="~QXtWidget"></a>QXtWidget::~QXtWidget ()
|
|---|

|

| 115 | Destructs the QXtWidget.

|
|---|
| 117 | <h3 class=fn>bool <a name="isActiveWindow"></a>QXtWidget::isActiveWindow () const
|

|

| 119 | Different from <a href="qwidget.html#isActiveWindow">QWidget::isActiveWindow</a>()
|
|---|
| 120 |
|
|---|
| 121 | <h3 class=fn>void <a name="setActiveWindow"></a>QXtWidget::setActiveWindow ()<tt> [virtual]</tt>
|
|---|
| 122 | </h3>
|
|---|
| 123 | Implement a degree of focus handling for Xt widgets.
|
|---|
| 124 |
|
|---|
| 125 | <p>Reimplemented from <a href="qwidget.html#setActiveWindow">QWidget</a>.
|
|---|
| 126 | <h3 class=fn>bool <a name="x11Event"></a>QXtWidget::x11Event ( XEvent * e )<tt> [virtual protected]</tt>
|
|---|
| 127 | </h3>
|
|---|
| 128 | Reimplemented to produce the Xt effect of getting focus when the
|
|---|
| 129 | mouse enters the widget. The event is passed in <em>e</em>.
|
|---|
| 130 |
|
|---|
| 131 | <p>Reimplemented from <a href="qwidget.html#x11Event">QWidget</a>.
|
|---|
| 132 | <h3 class=fn>Widget <a name="xtWidget"></a>QXtWidget::xtWidget () const
|
|---|
| 133 | </h3>
|
|---|
| 134 |
|
|---|
| 135 | <p> Returns the Xt widget equivalent for the Qt widget.
