Interface DrawingTool

All Known Implementing Classes:
  OMDrawingTool

public interface DrawingTool

A DrawingTool is an object that can take a request for editing an OMGraphic, or for creating an OMGraphic from a classname, and find a EditTool to do the job. The DrawingTool is responsible for providing any user interface that is needed to adjust the OMGraphic.

Method Summary
`void` | `addLoader(EditToolLoader loader)` Add an EditToolLoader to the DrawingTool, expanding the DrawingTool's capability to handle more graphic types.
`boolean` | `canEdit(java.lang.Class clas)` Check to see if the class type can be created/edited by the DrawingTool.
`OMGraphic` | `create(java.lang.String classname, DrawingToolRequestor requestor)` Given a classname, provide an OMGraphic for that classname.
`OMGraphic` | `create(java.lang.String classname, GraphicAttributes ga, DrawingToolRequestor requestor)` Given a classname, provide an OMGraphic for that classname.
`OMGraphic` | `create(java.lang.String classname, GraphicAttributes ga, DrawingToolRequestor requestor, boolean showGUI)` Same as create(String, GraphicAttributes, DrawingToolRequestor), except that you have to option of supressing the GUI that could be available from the EditableOMGraphic.
`OMGraphic` | `edit(EditableOMGraphic eomg, DrawingToolRequestor requestor)` Given an EditableOMGraphic, direct events to the EditableOMGraphic so that it can modify its OMGraphic.
`OMGraphic` | `edit(EditableOMGraphic eomg, DrawingToolRequestor requestor, java.awt.event.MouseEvent e)` A slightly different edit method, where the EditableOMGraphic is put directly into edit mode, and the mouse events immediately start making modifications to the OMGraphic.
`OMGraphic` | `edit(OMGraphic g, DrawingToolRequestor requestor)` Given an OMGraphic, set things up so that the OMGraphic will be edited.
`OMGraphic` | `edit(OMGraphic g, DrawingToolRequestor requestor, boolean showGUI)` Same as edit(omGraphic, DrawingToolRequestor), except that you have to option of supressing the GUI that could be available from the EditableOMGraphic.
`OMGraphic` | `edit(OMGraphic g, DrawingToolRequestor requestor, java.awt.event.MouseEvent e)` A slightly different edit method, where the EditableOMGraphic is put directly into edit mode, and the mouse events immediately start making modifications to the OMGraphic.
`int` | `getBehaviorMask()` A integer that is looked at internally, bitwise, to determine different behaviors.
`EditToolLoader[]` | `getLoaders()` Get an array of EditToolLoaders that the DrawingTool knows about.
`void` | `removeLoader(EditToolLoader loader)` Remove an EditToolLoader from the DrawingTool.
`void` | `setBehaviorMask(int mask)` A integer that is looked at internally, bitwise, to determine different behaviors.
`void` | `setLoaders(EditToolLoader[] loaders)` Set the loaders within the DrawingTool.

Method Detail

### setBehaviorMask

    public void setBehaviorMask(int mask)

  A integer that is looked at internally, bitwise, to determine different behaviors. If you care about specific behavior of the DrawingTool, you should set this to what you want to make sure the tool acts the way you want.

### getBehaviorMask

    public int getBehaviorMask()

  A integer that is looked at internally, bitwise, to determine different behaviors.

### create

    public OMGraphic create(java.lang.String classname,
                            DrawingToolRequestor requestor)

  Given a classname, provide an OMGraphic for that classname. It's assumed that the DrawingTool will be holding on to an EditableOMGraphic encasing the returned OMGraphic, and that the parameters of the OMGraphic may still change depending on user input.

  Parameters:
    `classname` - the classname of the OMGraphic to create.
    `requestor` - the Component that is requesting the OMGraphic. The requestor gets notified when the user is finished with the DrawingTool and the graphic is ready.
  Returns:
    OMGraphic if everything's OK, null if the request can't be fulfilled.

### create

    public OMGraphic create(java.lang.String classname,
                            GraphicAttributes ga,
                            DrawingToolRequestor requestor)

  Given a classname, provide an OMGraphic for that classname. It's assumed that the DrawingTool will be holding on to an EditableOMGraphic encasing the returned OMGraphic, and that the parameters of the OMGraphic may still change depending on user input.

  Parameters:
    `classname` - the classname of the OMGraphic to create.
    `ga` - GraphicAttributes object that contains more information about the type of line to be created.
    `requestor` - the Component that is requesting the OMGraphic. The requestor gets notified when the user is finished with the DrawingTool and the graphic is ready.
  Returns:
    OMGraphic if everything's OK, null if the request can't be fulfilled.

### create

    public OMGraphic create(java.lang.String classname,
                            GraphicAttributes ga,
                            DrawingToolRequestor requestor,
                            boolean showGUI)

  Same as create(String, GraphicAttributes, DrawingToolRequestor), except that you have to option of supressing the GUI that could be available from the EditableOMGraphic.

  Parameters:
    `classname` - the classname of the OMGraphic to create.
    `ga` - GraphicAttributes object that contains more information about the type of line to be created.
    `requestor` - the Component that is requesting the OMGraphic. The requestor gets notified when the user is finished with the DrawingTool and the graphic is ready.
    `showGUI` - set to true (default) if a GUI showing attribute controls should be displayed.
  Returns:
    OMGraphic if everything's OK, null if the request can't be fulfilled.

### edit

    public OMGraphic edit(OMGraphic g,
                          DrawingToolRequestor requestor)

  Given an OMGraphic, set things up so that the OMGraphic will be edited. Returns the OMGraphic being edited. Shouldn't assume that the two objects are the same. It's assumed that the DrawingTool will be holding on to an EditableOMGraphic encasing the returned OMGraphic, and that the parameters of the OMGraphic may still change depending on user input.

  Parameters:
    `g` - the OMGraphic to wrap in an EditableOMGraphic, and therefore to edit.
    `requestor` - the Component that is requesting the OMGraphic. The requestor gets notified when the user is finished with the DrawingTool and the graphic is ready.
  Returns:
    OMGraphic if everything's OK, null if the request can't be fulfilled.

### edit

    public OMGraphic edit(OMGraphic g,
                          DrawingToolRequestor requestor,
                          boolean showGUI)

  Same as edit(omGraphic, DrawingToolRequestor), except that you have to option of supressing the GUI that could be available from the EditableOMGraphic.

  Parameters:
    `g` - the OMGraphic to wrap in an EditableOMGraphic, and therefore to edit.
