| 19 | * | |
| 20 | * DefaultModalGraphMouse is a PluggableGraphMouse class that | |
| 21 | * pre-installs a large collection of plugins for picking and | |
| 22 | * transforming the graph. Additionally, it carries the notion | |
| 23 | * of a Mode: Picking or Translating. Switching between modes | |
| 24 | * allows for a more natural choice of mouse modifiers to | |
| 25 | * be used for the various plugins. The default modifiers are | |
| 26 | * intended to mimick those of mainstream software applications | |
| 27 | * in order to be intuitive to users. | |
| 28 | * | |
| 29 | * To change between modes, two different controls are offered, | |
| 30 | * a combo box and a menu system. These controls are lazily created | |
| 31 | * in their respective 'getter' methods so they don't impact | |
| 32 | * code that does not intend to use them. | |
| 33 | * The menu control can be placed in an unused corner of the | |
| 34 | * GraphZoomScrollPane, which is a common location for mouse | |
| 35 | * mode selection menus in mainstream applications. | |
