The SoQtPlaneViewer class is for examining 3D models by moving the camera in orthogonal planes.
The SoQtPlaneViewer is a viewer that is useful for "CAD-style" applications, where you want the end-user to examine your model with the viewpoint set from one of the three principal axes.
Controls:
hold down left mouse button and move mouse pointer to dolly (or hold both left and middle mouse buttons)
hold middle mouse button to pan (or a CTRL-key plus left mouse button, or a SHIFT-key plus left mouse button)
hold down CTRL + middle mouse button to rotate (or CTRL + SHIFT + the left mouse button)
click 's', then pick with the left mouse button to seek
right mouse button open the pop-up menu
click 'ESC' key to switch to and from 'view' mode and 'scene graph interaction' mode (see setViewing() documentation)
hold down the 'ALT' key to temporary toggle from
camera-interaction mode to scene graph-interaction mode
Hitting any of the X, Y or Z buttons in the panel on the right side of the render canvas will "flip" the current camera direction around its focal point to point along the selected axis (towards negative infinity).
The SoQtPlaneViewer also provides a user decoration's button for toggling between orthographic or perspective camera view volumes and projection methods. This is the bottom-most click button on the right decoration border.
It also inherits the decoration buttons from the SoQtFullViewer: the arrow for switching to "scene graph interaction" mode, the hand for setting back to "camera interaction" mode, the house for "reset camera to home position", the blueprint house for "set new camera home position", the eye for "zoom camera out to view full scene" and the flashlight for setting "click to seek" mode.
Note that a common faulty assumption about all the viewer-classes is that user interaction (in the "examine"-mode, not the scene graph-interaction mode) influences the model or 3D-scene in the view. This is not correct, as it is always the viewer's camera that is translated and rotated.
The initial position of the camera is placed such that all of the scene graph's geometry fits within its view.

This method instantly redraws the normal (non-overlay) scene graph by calling SoSceneManager::render().
Subclasses may override this method to add their own rendering before or after Coin renders its scene graph.
The following is a complete example that demonstrates one way of adding both a background image and foreground (overlay) geometry to the "normal" rendering:

A function "hook" / callback invoked just after the window for the component has been realized.
Override this if you need specific initialization for your own component or viewer class to happen right after it has been made visible, but remember to call upwards in the inheritance hierarchy:

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 its 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 its 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:

Toolkit-native events are tried to convert 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 its subclasses to catch events of particular interest to the viewer classes, for instance.
Return TRUE
if 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.

Set the camera we want the viewer to manipulate when interacting with the viewer controls.
The camera passed in as an argument to this method must already be part of the viewer's scene graph. You do not inject viewpoint cameras to the viewer with this method.
You should rather insert a camera into the scene graph first (if necessary, often one will be present already), then register it as the camera used by the viewer controls with this method.
If the application code doesn't explicitly set up a camera through this method, the viewer will automatically scan through the scene graph to find a camera to use. If no camera is available in the scene graph at all, it will set up its own camera.

Set whether or not the mouse cursor representation should be visible in the viewer canvas.

Put the viewer in or out of "waiting-to-seek" mode.
If the user performs a mouse button click when the viewer is in "waiting-to-seek" mode, the camera will be repositioned so the camera focal point lies on the point of the geometry under the mouse cursor.
Reimplemented from SoQtViewer.

Set view mode.
If the view mode is on, user events will be caught and used to influence the camera position / orientation. If view mode is off, all events in the viewer canvas (like for instance keypresses or mouse clicks and -movements) will be passed along to the scene graph.
Default is to have the view mode active.
