Detailed Description
This class is defined in the Qt NSPlugin Extension, which can be found in the qt/extensions directory. It is not included in the main Qt API.
The QNPWidget class provides a QWidget that is a Web-browser plugin window.
Derive from QNPWidget to create a widget that can be used as a Browser plugin window, or create one and add child widgets. Instances of QNPWidget may only be created when QNPInstance::newWindow() is called by the browser.
A common way to develop a plugin widget is to develop it as a stand-alone application window, then make it a child of a plugin widget to use it as a browser plugin. The technique is:
class MyPluginWindow : public QNPWidget { QWidget* child; public: MyPluginWindow() { // Some widget that is normally used as a top-level widget child = new MyIndependentlyDevelopedWidget(); // Use the background color of the web page child->setBackgroundColor( backgroundColor() ); // Fill the plugin widget child->setGeometry( 0, 0, width(), height() ); } void resizeEvent(QResizeEvent*) { // Fill the plugin widget child->resize(size()); } };
The default implementation is an empty window.
Member Function Documentation
QNPWidget::QNPWidget ()
Creates a QNPWidget.QNPWidget::~QNPWidget ()
Destroys the window. This will be called by the plugin binding code when the window is no longer required. The Web-browser will delete windows when they leave the page. The bindings will change the QWidget::winId() of the window when the window is resized, but this should not affect normal widget behavior.void QNPWidget::enterInstance () [virtual]
Called when the mouse enters the plugin window. Does nothing by default.Example: grapher/grapher.cpp.
QNPInstance * QNPWidget::instance ()
Returns the instance for which this widget is the window.void QNPWidget::leaveInstance () [virtual]
Called when the mouse leaves the plugin window. Does nothing by default.Example: grapher/grapher.cpp.
