Detailed Description

This class is defined in the Qt Motif Extension, which can be found in the qt/extensions directory. It is not included in the main Qt API. +

+ +The QXtWidget class allows mixing of Xt/Motif and Qt widgets. +This class is obsolete. It is provided to keep old source working. We strongly advise against using it in new code. +

QXtWidget acts as a bridge between Xt and Qt. For utilizing old Xt +widgets, it can be a QWidget based on a Xt widget class. For +including Qt widgets in an existing Xt/Motif application, it can be +a special Xt widget class that is a QWidget. See the constructors +for the different behaviors. +

Known QXtWidget Problems +

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 not +be fixed in future releases. +

Below is an imcomplete list of know issues: +

Keyboard focus navigation is impossible when using QXtWidget. +The mouse must be used to focus widgets in both Qt and Xt/Motif +widgets. For example, when embedding a QXtWidget into an Xt/Motif +widget, key events will go to the QXtWidget (and its children) while +the mouse is over the QXtWidget, regardless of where Xt/Motif has +placed the focus. +
Reparenting does not work. You cannot use +QWidget::reparent(). This includes the functions +QWidget::showFullScreen() and QWidget::showNormal(), which use +QWidget::reparent(). +

+ +

Member Function Documentation

QXtWidget::QXtWidget ( const char * name, Widget parent, bool managed = FALSE ) +

+Constructs a QXtWidget of the special Xt widget class known as +"QWidget" to the resource manager. +

Use this constructor to utilize Qt widgets in an Xt/Motif +application. The QXtWidget is a QWidget, so you can create +subwidgets, layouts, etc. using Qt functionality. +

The name is the object name passed to the QWidget constructor. +The widget's parent is parent. +

If the managed parameter is TRUE and parent in not null, +XtManageChild it used to manage the child. + +

QXtWidget::QXtWidget ( const char * name, WidgetClass widget_class, QWidget * parent = 0, ArgList args = 0, Cardinal num_args = 0, bool managed = FALSE ) +

+Constructs a QXtWidget of the given widget_class called name. +

Use this constructor to utilize Xt or Motif widgets in a Qt +application. The QXtWidget looks and behaves +like the Xt class, but can be used like any QWidget. +

Note that Xt requires that the most top level Xt widget is a shell. +This means, if parent is a QXtWidget, the widget_class can be +of any kind. If there isn't a parent or the parent is just a normal +QWidget, widget_class should be something like topLevelShellWidgetClass. +

The arguments, args, num_args are passed on to XtCreateWidget. +

If the managed parameter is TRUE and parent in not null, +XtManageChild it used to manage the child. + +

QXtWidget::~QXtWidget () +

+Destructs the QXtWidget. + +

bool QXtWidget::isActiveWindow () const +

+Different from QWidget::isActiveWindow() + +

void QXtWidget::setActiveWindow () `[virtual]` +

+Implement a degree of focus handling for Xt widgets. + +

Reimplemented from QWidget. +

bool QXtWidget::x11Event ( XEvent * e ) `[virtual protected]` +

+Reimplemented to produce the Xt effect of getting focus when the +mouse enters the widget. The event is passed in e. + +

Reimplemented from QWidget. +

Widget QXtWidget::xtWidget () const +

+ +

Returns the Xt widget equivalent for the Qt widget. + + +
