DESCRIPTION

23       This class is defined in the Qt Netscape Extension, which can be found
24       in the qt/extensions directory. It is not included in the main Qt API.
25
26       The QNPWidget class provides a QWidget that is a web browser plugin
27       window.
28
29       Derive from QNPWidget to create a widget that can be used as a web
30       browser plugin window, or create one and add child widgets. Instances
31       of QNPWidget may only be created when QNPInstance::newWindow() is
32       called by the browser.
33
34       A common way to develop a plugin widget is to develop it as a stand-
35       alone application window, then make it a child of a plugin widget to
36       use it as a browser plugin. The technique is:
37
38       class MyPluginWindow : public QNPWidget
39       {
40           QWidget* child;
41       public:
42           MyPluginWindow()
43           {
44               // Some widget that is normally used as a top-level widget
45               child = new MyIndependentlyDevelopedWidget();
46               // Use the background color of the web page
47               child->setBackgroundColor( backgroundColor() );
48               // Fill the plugin widget
49               child->setGeometry( 0, 0, width(), height() );
50           }
51           void resizeEvent(QResizeEvent*)
52           {
53               // Fill the plugin widget
54               child->resize(size());
55           }
56       };
57
58       The default implementation is an empty window.

MEMBER FUNCTION DOCUMENTATION

QNPWidget::QNPWidget ()
62       Creates a QNPWidget.
63

QNPWidget::~QNPWidget ()
65       Destroys the window. This will be called by the plugin binding code
66       when the window is no longer required. The web browser will delete
67       windows when they leave the page. The bindings will change the
68       QWidget::winId() of the window when the window is resized, but this
69       should not affect normal widget behavior.
70

void QNPWidget::enterInstance () [virtual]
72       Called when the mouse enters the plugin window. Does nothing by
73       default.
74
75       Example: grapher/grapher.cpp.
76

QNPInstance * QNPWidget::instance ()
78       Returns the instance for which this widget is the plugin window.
79

void QNPWidget::leaveInstance () [virtual]
81       Called when the mouse leaves the plugin window. Does nothing by
82       default.
83
84       Example: grapher/grapher.cpp.
