Detailed Description

Cubic object you can translate and scale by dragging with the mouse.

SoTabBoxDragger is a composite dragger shaped like a box. Inside it are six SoTabPlaneDraggers which the dragger positions and orients to form a cube. The operations available in an SoTabPlaneDragger (translation, 1D scaling and 2D scaling) are available on each face of the cube. Since they each move in their own local space, the dragger may be easily translated or scaled in any direction.

Clicking and dragging a corner tab does a 2D scaling in the plane of the tab by scaling, centered on the opposite corner of that face of the dragger, meaning that the opposite corner is the only corner that won't move.
Note: Holding the SHIFT key while dragging a corner tab forces uniform scaling.

Clicking and dragging an edge tab does 1D scaling about the opposite edge of that face.

Clicking and dragging a face does translation within the plane of the face. Although the face of the dragger is invisible (using the default dragger geometry) it is pickable.
Note: Holding the SHIFT key while dragging a face forces axis constrained dragging. The drag axis is determined by the initial drag direction.

As a composite dragger, this class makes sure that when one plane is dragged, the entire box moves together.

Each SoTabPlaneDragger tries to keep the small tabs a constant size in screen space. Every time a drag begins or ends, the size is automatically recalculated based on the viewing and modeling matrix. When the resizeHandles field is set to TRUE (the default), the tab size is also recalculated during the render traversal if the view matrix has changed (usually because the camera position and/or orientation changed). The application can also force the tab size to be recomputed by calling the adjustScaleTabSize() method.

If the dragger becomes too small in one dimension to contain all three tabs (two corner tabs plus the edge tab), the middle (edge) tab will not be drawn. If the dragger becomes very small (or flat) in one dimension, it may not be possible for the user to resize using the tabs. One solution for this is to provide a "reset dragger" button in the application.

When dragging the translator part, press the <Shift> key and you can constrain motion to either the local x axis or the y axis . The direction is determined by your initial mouse gesture after pressing the key. Releasing the key removes the constraint.

As each sub-dragger is moved, the SoTabBoxDragger updates its scaleFactor and translation fields. As with all draggers, if you change a field the dragger will move to match the new settings.

Remember: This is not an SoTransform!. If you want to move other objects with this dragger, you can:

• Use an SoTabBoxManip, which is subclassed from SoTransform. It creates one of these draggers and uses it as the interface to change its fields.
• Use an SoROIManip, which is subclassed from SoROI, if your goal is to do volume rendering and interact with a region-of-interest. This is commonly used for medical volume data and seismic volume data.
• Use field-to-field connections to connect the fields of this dragger to those of any SoTransformation node.
• Use the standard dragger callbacks, see for example SoDragger::addValueChangedCallback.

You can change the parts in any instance of this dragger using setPart(). The default part geometries are defined as resources for this SoTabBoxDragger class. They are detailed below in the Dragger Resources section of the online reference page for this class. You can make your program use different default resources for the parts by copying the file $OIVHOME/data/draggerDefaults/tabBoxDragger.iv into your own directory, editing the file, and then setting the environment variable SO_DRAGGER_DIR to be a path to that directory.

This dragger has both a default and a WYSIWYG version:
