Detailed Description

widget to show Qt and VTK messages.

This utility class allows us to install a Qt message handler. We are using a signal/slot to ensure that the messages are written on the main thread.

This utility class also helps us support VTK messages coming from different threads.

N.B. This is really a internal class however has to be exported so it can be used inside a message handler function inside Qt.

Constructor & Destructor Documentation

MessageHandler::MessageHandler ( QObject * parent = nullptr )

static void MessageHandler::install ( pqOutputWidget * widget )

static

This function can be used to install a message handler for Qt that forwards all messages generated by Qt to the vtkOutputWindow instance obtained by vtkOutputWindow::GetInstance().

Thus, this is quick way to forward all Qt messages to be forwarded to VTK for output using the same mechanisms setup for handling VTK messages.

static void MessageHandler::handler	(	QtMsgType	type,
		const QMessageLogContext &	,
		const QString &	msg
	)

static

This is the function installed with Qt.

static void MessageHandler::handlerVTK	(	QtMsgType	type,
		const QString &	msg

This function is used for VTK messages that don't have QMessageLogContext.
