Detailed Description

The SoQtFullViewer class adds some user interface components to the viewer canvas.

The SoQtFullViewer is an abstract viewer class which extends it's superclass (the basic SoQtViewer class) with two major user interface additions:

o decorations around the render canvas, with buttons and thumbwheels to: control camera interaction and various other aspects of model / scene viewing
o a popup menu, invoked with the right mouse button, which controls yet: more aspects of the rendering and the viewer
The user interface features listed above are the common parts of the
user interfaces of the SoQtFullViewer's non-abstract subclasses.
For 'real' application programs, the viewers / components from this
class onwards and further down in the inheritance hierarchy is usually not all that interesting, as they enforces too much extra user
interface cruft not compatible with the look and feel of the other
parts of the application user interface. So most 'real' applications
will use either the SoQtViewer or the SoQtRenderArea as their baselevel component, and then inherit one of these down into one's own
'proper' viewer classes.
The non-abstract subclasses of the SoQtFullViewer class are viewer components often used as a test-bed for prototyping / rapid application development when doing quick testing of scenes, stand-alone 3D-models, animation techniques, etc etc.

Member Enumeration Documentation

enum SoQtFullViewer::BuildFlag Valid values for the constructor argument: that decides how much of the user interface features to set up. The enum values are bitflags that can be OR'ed together. Enumerator:
BUILD_NONE
Do not add any of the user interface components.; BUILD_DECORATION
Only build and set up the decorations around the OpenGL canvas.; BUILD_POPUP
Only build the popup menu. (Activated with the right
mousebutton.); BUILD_ALL
Build all user interface components of the SoQtFullViewer.

Constructor & Destructor Documentation

SoQtFullViewer::SoQtFullViewer (QWidget * parent, const char * name, SbBool: embed, SoQtFullViewer::BuildFlag buildFlag, SoQtViewer::Type type, SbBool build) [protected] Constructor. See parent class for explanation of arguments.
Subclasses will probably usually call with the buildNow flag set to FALSE to be able to do delayed building of the OpenGL canvas after
other setup tasks has been performed.

// 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

}

One important note if you want to override this method to add your own buttons to the list (in the explanation below, it is assumed that you
know how virtual function table pointers are handled by C++):
createViewerButtons() is called (indirectly) from the constructors of the viewer classes. This means that you need to delay it's invocation
until your own subclass's constructor is run, because otherwise your
re-implementation won't have been added to the internal virtual
function table yet.
Delaying a superclass viewer from building it's decorations is done by passing build==FALSE as the last argument of the protected
constructors. You will then have to explicitly trigger the building in your own constructor.
Here's a minimal example that shows the steps needed to be able to
override createViewerButtons() from SoQtExaminerViewer:
class MyExaminerViewer : public SoQtExaminerViewer {

public:
MyExaminerViewer(QWidget * parent);

protected:

virtual void createViewerButtons(QWidget * parent, SbPList * buttonlist);

};

MyExaminerViewer::MyExaminerViewer(QWidget * parent)

: SoQtExaminerViewer(parent, NULL, TRUE,
SoQtFullViewer::BUILD_ALL, SoQtFullViewer::BROWSER, // build == FALSE, to delay creation of decorations FALSE)

{

// Explicitly trigger the construction of viewer decorations.
QWidget * widget = this->buildWidget(this->getParentWidget());
this->setBaseWidget(widget);

}

void
MyExaminerViewer::createViewerButtons(QWidget * parent, SbPList * buttonlist) {

SoQtExaminerViewer::createViewerButtons(parent, buttonlist);
// [now add your own button(s) to the buttonlist]

}

SoQtPlaneViewer::createViewerButtons(), and
SoQtExaminerViewer::createViewerButtons().

void SoQtFullViewer::buildPopupMenu (void) [protected, virtual] Make a

popup menu with preferences settings. One important note as for when you want to override this function in a subclass: be aware that it will usually be invoked (indirectly) from
this class's constructor. That is before the table of virtual function pointers has been set up for the subclass, and because of this, the
function will not be called in the subclass even though it is virtual. To make the overriding actually be in effect, you need to delay
building the widgets of this class. For information on how to do that, see the documentation of SoQtFullViewer::createViewerButtons(). References prefmenu.

SbBool SoQtFullViewer::processSoEvent (const SoEvent *const event)

[protected, virtual] Toolkit-native events are attempted converted to Coin-generic events in the SoQtRenderArea::processEvent() method. If this succeeds, they are forwarded to this method. This is a virtual method, and is overridden in it's subclasses to catch events of particular interest to the viewer classes, for instance.
Return TRUE iff the event was processed. If not it should be passed on further up in the inheritance hierarchy by the caller. This last point is extremely important to take note of if you are expanding the toolkit with your own viewer class.
This method is not part of the original SGI InventorXt API. Note that
you can still override the toolkit-native processEvent() method instead of this 'generic' method.
