Detailed Description

Base class for all viewer nodes in MeVisLab.

Since the SoQtExaminerViewer etc. are not SoNode classes and have no way to save their state persistently, we decided to wrap all viewers and their creation/persistence in the SoViewerNode and it's derived classes. The mostly used SoViewerNodes are located in the SoViewers project, e.g. the SoRenderArea and SoExaminerViewer. In many cases when you want to add a viewer to MeVisLab, you would derive either from the SoRenderArea or SoFullViewer class and not from this base class.

Member Function Documentation

◆ createViewer()

virtual void* SoViewerNode::createViewer	(	void *	hwnd,
		SoNode *	scene
	)

virtual

create a viewer in the given window, the scene is shown in the viewer

void pointer is used to be compatible to any windows system, on Qt it is a QWidget, on TGS SoWin it is a HWND. Only one viewer can be created at a time.

Reimplemented in SoRenderArea, SoFullViewer, and SoExaminerViewer.

◆ deleteViewer()

virtual void SoViewerNode::deleteViewer ( void * viewer )

virtual

delete the viewer that was created with createViewer

Reimplemented in SoRenderArea, and SoFullViewer.

◆ generateMovie()

void SoViewerNode::generateMovie	(	const char *	name,
		const char *	extension,
		int	count,
		float	framerate,
		const char *	targetFile = `nullptr`
	)

inline

run move generation

Definition at line 88 of file SoViewerNode.h.

◆ getCurrentViewer()

virtual void* SoViewerNode::getCurrentViewer ( )

inlinevirtual

returns the currently viewer (or NULL, if none was created)

Definition at line 61 of file SoViewerNode.h.

bool SoViewerNode::handleEventNotify ( void * message )

inline

run handle event cb

Definition at line 79 of file SoViewerNode.h.

◆ initClass()

static void SoViewerNode::initClass ( )

static

◆ keyPressedNotify()

bool SoViewerNode::keyPressedNotify ( void * message )

inline

Definition at line 70 of file SoViewerNode.h.

◆ setGenerateMovieCB()

void SoViewerNode::setGenerateMovieCB	(	InvGenerateMovieCB *	cb,
		void *	data
	)

inline

set movie generation callback

Definition at line 85 of file SoViewerNode.h.

◆ setHandleEventCB()

void SoViewerNode::setHandleEventCB	(	InvHandleEventCB *	cb,
		void *	data
	)

inline

set a handle event callback

Definition at line 76 of file SoViewerNode.h.

◆ setKeyPressedCB()

void SoViewerNode::setKeyPressedCB	(	InvKeyPressedCB *	cb,
		void *	data
	)

inline

Definition at line 67 of file SoViewerNode.h.

◆ syncFromViewerNode()

virtual void SoViewerNode::syncFromViewerNode ( SoViewerNode * )

inlinevirtual

sync field from given src viewer node (derive to add more synched fields)

Reimplemented in SoRenderArea.

Definition at line 64 of file SoViewerNode.h.
