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:

decorations around the render canvas, with buttons and thumbwheels to control camera interaction and various other aspects of model / scene viewing
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 base-level 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.

See Also: SoQtConstrainedViewer, SoQtExaminerViewer, SoQtPlaneViewer

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. 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.

Returns the widget which is used as the parent of application specified buttons. The row of application buttons (if any) will be placed in the upper left corner.

See Also: addAppPushButton(), insertAppPushButton(), removeAppPushButton()

Referenced by addAppPushButton(), insertAppPushButton(), and removeAppPushButton().

void SoQtFullViewer::addAppPushButton ( QWidget * newButton )

Default is to have the view mode active.

void SoQtFullViewer::setComponentCursor ( const SoQtCursor & cursor )

virtual

Sets the cursor for this component.

Note: not part of the original SGI InventorXt API.

Reimplemented from SoQtComponent.

References SoQtGLWidget::getGLWidget(), and SoQtComponent::setWidgetCursor().

void SoQtFullViewer::sizeChanged ( const SbVec2s & size )

protectedvirtual

Called internally from within the SoQt library when the widget embedded in a component changes it size, which is usually triggered by end-user interaction.

This method is then invoked to notify the component that the size has changed. It is called from the top and all the way down to the bottom, the size being adjusted to take into account extra decorations having been added at each level in the component class hierarchy.

Reimplemented from SoQtViewer.

QWidget * SoQtFullViewer::buildWidget ( QWidget * parent )

protected

This method builds the component contents in the given parent widget. For subclasses adding new user interface items, this method is typically overridden in the following manner:

QWidget * MyOwnViewer::buildWidget(QWidget * parent)
{
   QWidget * superw = <superclass>::buildWidget(parent);
   // [then move superw within MyOwnViewer framework and add own
   // user interface components]
}

QWidget * SoQtFullViewer::buildViewerButtons ( QWidget * parent )

References createViewerButtons().

Referenced by buildRightTrim().

void SoQtFullViewer::createViewerButtons	(	QWidget *	parent,
		SbPList *	buttonlist
	)

protectedvirtual

Set up the viewer buttons with pixmaps and event connections.

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]
}

Reimplemented in SoQtExaminerViewer, and SoQtPlaneViewer.

References SoQtViewer::isViewing().

Referenced by buildViewerButtons().

void SoQtFullViewer::buildPopupMenu ( void )

protectedvirtual

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().

void SoQtFullViewer::rightWheelFinish ( void )

protectedvirtual

Called as the user let go of the thumbwheel in the right frame after a drag operation. Override this method in subclassed viewers to provide your own functionality on the thumbwheel.

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

protectedvirtual

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.
