.PP
The \fBSoQtObject\fP class is the common superclass for all \fBSoQt\fP component classes\&.
.PP
The purpose of making this class the superclass of all \fBSoQt\fP device, component and viewer classes is to be able to do run-time type checking of the \fBSoQt\fP objects\&.

.SH "Detailed Description"
.PP 
The \fBSoQtObject\fP class is the common superclass for all \fBSoQt\fP component classes\&.
.PP
The purpose of making this class the superclass of all \fBSoQt\fP device, component and viewer classes is to be able to do run-time type checking of the \fBSoQt\fP objects\&. 

You can place the macro SOQT_OBJECT_HEADER(classname,parentname) within a class definition header for \fBSoQt\fP extension components to automatically make the necessary definitions for setting up a run-time type system for your extension classes:
.PP
.PP
.nf
  #ifndef MYSPECIALVIEWER_H
  #define MYSPECIALVIEWER_H

  class MySpecialViewer : public SoQtExaminerViewer {
    SOQT_OBJECT_HEADER(MySpecialViewer, SoQtExaminerViewer);
    // [rest of class definition follows]
  };

  #endif // !MYSPECIALVIEWER_H
.fi
.PP
.PP
Then put the SOQT_OBJECT_SOURCE(classname) macro within the actual implementation sourcecode file to include the necessary code for the run-time type system:
.PP
.PP
.nf
  #include <MySpecialViewer\&.h>

  SOQT_OBJECT_SOURCE(MySpecialViewer);

  // [rest of class implementation]
.fi
.PP
.PP

.SS "void \fBSoQtObject::initClass\fP (void)\fC [static]\fP"Sets up initialization for data common to all instances of this class, submitting necessary information to the internal \fBSoQt\fP type system\&. 
.PP
Referenced by init(), SoQtDevice::initClasses(), and SoQtComponent::initClasses()\&.
.SS "SoType \fBSoQtObject::getClassTypeId\fP (void)\fC [static]\fP"This static method returns the SoType object associated with objects of this class\&. 
.PP
Referenced by SoQtViewer::setCameraType(), SoQtViewer::setSceneGraph(), SoQtRenderArea::sizeChanged(), SoQtViewer::SoQtViewer(), and SoQtViewer::toggleCameraType()\&.
.SS "SoType \fBSoQtObject::getTypeId\fP (void) const\fC [pure virtual]\fP"Returns the type identification of an object derived from a class inheriting \fBSoQtObject\fP\&. This is used for run-time type checking and 'downward' casting\&.
.PP
Usage example:
.PP
.PP
.nf
  void foo(SoQtViewer * comp)
  {
    if (comp->getTypeId() == SoQtExaminerViewer::getClassTypeId()) {
      // safe downward cast, knows the type
      SoQtExaminerViewer * exviewer = (SoQtExaminerViewer *)comp;
    }
    else if (comp->getTypeId()\&.isOfType(SoQtFlyViewer::getClassTypeId())) {
      // safe downward cast, knows the type
      SoQtFlyViewer * flyviewer = (SoQtFlyViewer *)comp;
      // then something else
    }
  }
.fi
.PP
 
.PP
Referenced by isOfType(), and SoQtRenderArea::sizeChanged()\&.
.SS "SbBool \fBSoQtObject::isOfType\fP (SoTypetype) const"Returns \fCTRUE\fP if the type of this object is either of the same type or inherited from \fItype\fP\&. 
.PP

.SS "void \fBSoQtObject::init\fP (void)\fC [static]\fP"Initialize the type system of \fBSoQtObject\fP, all \fBSoQt\fP device classes and all \fBSoQt\fP components (including viewers)\&.
