Remarks

OIV.Inventor.Draggers.SoTabPlaneDragger is a dragger which allows the user to interactively translate and scale in a plane. It looks like a square white outline with smaller green squares (or tabs ) set in the corners and along the center of each edge.

Dragging a corner tab scales the dragger in 2D by scaling about the opposite corner. Holding the SHIFT key while while dragging a corner tab forces uniform scaling.

Dragging an edge tab performs 1D scaling about the opposite edge.

Uniform scaling can also be forced by setting the OIV.Inventor.Draggers.SoTabPlaneDragger.scaleUniform field to true.

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.

The dragger tries to keep the small tabs a constant size in screen space. Before version 7.0, this adjustment was only done when a drag operation started and ended, or when the OIV.Inventor.Draggers.SoTabPlaneDragger.AdjustScaleTabSize() method was called. Now as long as the OIV.Inventor.Draggers.SoTabPlaneDragger.resizeHandles field is set to true (the default), the tab size is automatically recalculated whenever the view matrix changes (normally because the camera position or orientation changed).

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.

When the translator part drags, the dragger updates its OIV.Inventor.Draggers.SoTabPlaneDragger.translation field. The various scaling parts cause changes to both the OIV.Inventor.Draggers.SoTabPlaneDragger.scaleFactor and OIV.Inventor.Draggers.SoTabPlaneDragger.translation field, since scaling about a point other than the center adds translation to the center of the dragger. If you set the field, the dragger will move accordingly. You can also connect fields of other nodes or engines from this one to make them follow the dragger's motion.

You can not change the shape used to draw the tabs. This part is kept privately and may not be changed; the coordinates for the tabs are edited during OIV.Inventor.Draggers.SoTabPlaneDragger.AdjustScaleTabSize().

The OIV.Inventor.Draggers.SoTabPlaneDragger class does contain three other parts you can change: tabPlaneTranslator , tabPlaneScaleTabMaterial and tabPlaneScaleTabHints .

Each of these is set by default from a resource described in the Dragger Resources section of the online reference page for this class. You can change the parts in any instance of this dragger using OIV.Inventor.Nodekits.SoBaseKit.SetPart(System.String, OIV.Inventor.Nodes.SoNode).

You can make your program use different default resources for the parts by copying the file $OIVHOME/data/draggerDefaults/tabPlaneDragger.iv into your own directory, editing the file, and then setting the environment variable SO_DRAGGER_DIR to be a path to that directory.

See OIV.Inventor.Draggers.SoDragger for more information about using and customizing draggers, including code examples, using draggers in an immersive VR environment and using WYSIWYG draggers.
