Examples with BoxSelectionPlugin au.gov.asd.tac.constellation.graph.interaction.plugins.select.BoxSelectionPlugin used on opensource projects

Example 1 with BoxSelectionPlugin

use of au.gov.asd.tac.constellation.graph.interaction.plugins.select.BoxSelectionPlugin in project constellation by constellation-app.

the class DefaultInteractionEventHandler method performBoxSelection.

/**
 * Performs a selection based on a given start and end point.
 *
 * If the start and end point are equal, a point selection is performed
 * based on the hit tester.
 *
 * If the start and end point differ, a box selection is performed with the
 * two points representing diagonally opposite corners of the box.
 *
 * In the latter case, the 2d box is actually converted to a 3d frustrum in
 * order to make the correct selection on the 3 dimensional graph.
 *
 * @param selectTo the point where selection ends
 * @param selectFrom the point where selection begins.
 * @param appendSelection whether or not the selection will be appended to
 * the current selection
 * @param toggleSelection whether or not the selection will toggle the
 * current selection. Note that if appendSelection is true, this parameter
 * has no effect.
