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 pop-up menu. (Activated with the right mouse button.)

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.

Destructor.

Turn the viewer decorations on or off.

See also

isDecoration()

Return TRUE if the viewer decorations are on, otherwise FALSE.

See also

setDecoration()

Decide whether or not if clicking with the right mouse button on the OpenGL canvas should reveal a preferences pop-up menu when in viewing mode.

See also

isPopupMenuEnabled()

Return TRUE if the pop-up preferences menu is enabled, otherwise FALSE.

See also

setPopupMenuEnabled()

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()

Add an application specific push button to the viewer decorations. Application buttons will be laid out in a vertical row from the upper left corner.

The button will be added bottom-most.

See also

insertAppPushButton(), removeAppPushButton(), getAppPushButtonParent()

Insert an application specific push button to the viewer decorations at the given index.

See also

addAppPushButton(), removeAppPushButton(), getAppPushButtonParent()

Remove one of the application specific buttons.

See also

addAppPushButton(), insertAppPushButton()

Return the index of a particular button that has been specified by the application, or -1 of the button has not been added.

See also

addAppPushButton()

Return number of application specific buttons added.

See also

addAppPushButton(), insertAddAppPushButton()

Returns the render area OpenGL canvas widget.

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.

See also

isViewing()

Reimplemented from SoQtViewer.

Reimplemented in SoQtExaminerViewer, SoQtFlyViewer, and SoQtPlaneViewer.

Sets the cursor for this component.

Note: not part of the original SGI InventorXt API.

Reimplemented from SoQtComponent.

Called internally from within the SoQt library when the widget embedded in a component changes its 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.

Build viewer decorations.

Build decorations on the left of the render canvas. Override this method in subclasses if you want your own decorations on the viewer window.

The decoration will be 30 pixels wide.

Build decorations on the bottom of the render canvas. Override this method in subclasses if you want your own decorations on the viewer window.

Build decorations on the right side of the render canvas. Override this method in subclasses if you want your own decorations on the viewer window.

Build the application specified button row (if any buttons were set up).

Build and layout viewer specified button row.

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:

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.

Make a pop-up 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().

Set title of pop-up menu.

NOTE: This method is not part of the original InventorXt API.

Called when the user starts to drag the thumbwheel in the left frame. Override this method in subclassed viewers to provide your own functionality on the thumbwheel.

See also

leftWheelMotion(), leftWheelFinish()

Called repeatedly as the user drags the thumbwheel in the left frame. Override this method in subclassed viewers to provide your own functionality on the thumbwheel.

Set label of the right thumbwheel.

This method returns the native widget for the label below the right thumb wheel.

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.
