getCurrentAttribs

public FigAttribs getCurrentAttribs()

Description copied from interface: FigBasicEditor

getCurrentAttribs: return a reference to the current editor global object attributes. Like many graphical editors, jfig maintains a single global attribute object to use for all new objects.

findObjectAt

public FigObject findObjectAt(java.awt.Point P)

findObjectAt: search the object list for an object near point P.

Currently, this method works in two passes as follows. In the first pass, the method will search for an object with one corner nearer than the cursor snap-distance from position P. The first such object will be returned.
If no object is found during the first pass, the search is repeated with less accuracy and will include all objects which are nearer than two (2) snap-distances to one corner and all objects which cover the position p.

getCallbackTable

public java.util.Hashtable getCallbackTable()

addCallback

public void addCallback(java.lang.String key,
                        java.lang.String methodname)

add an entry to our callback table. Use this method to call a method with name methodname as result of an ActionEvent evt with action command key.

For example, use something like the following: Button mandala = new Button( "create mandala" ); mandala.addActionListener( editor ); editor.addCallback( "create mandala", "doCreateMandala" ); Naturally, instead of adding callbacks via reflection, you can also create your own ModularEditor subclasses and override actionPerformed.

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent evt)

actionPerformed: process an action event using the global callback table.

Except for special handling of the 'undo' and 'redo' commands, this method works as follows. First, we collect the action event's evt String argument (getActionCommand()) in our internal variable s. The resulting string is then searched for in the global callback table. If found, we retrieve the callback method name from the callback table and use Java 1.1 reflection to call that method, i.e. call( s, evt ). If no callback method is found, an error message is printed.

Specified by:

actionPerformed in interface FigBasicEditor

call

public void call(java.lang.String s,
                 java.lang.Object arg)

Specified by:

itemStateChanged

public void itemStateChanged(java.awt.event.ItemEvent evt)

currently, this method is only used to set the default output FIG version

Specified by:

itemStateChanged in interface java.awt.event.ItemListener

isIdle

public boolean isIdle()

checkIsIdle

public boolean checkIsIdle()

checkCanCancel

public boolean checkCanCancel()

check whether the current command can be canceled. Currently this is true for all commands.

doCancel

public void doCancel(java.lang.Object arg)

doUndo

public void doUndo(java.lang.Object arg)

undo the topmost command from the undo stack. Note that the undo() method of that command object will automatically update/redraw the objects as needed. However, we have to ensure that any ongoing command is finished first, in order to get consistent data structures. We do this by canceling the current command first. Note that this may also modify the undo stack.

redo the topmost command from the undo stack. #see doUndo

mousePressed

public void mousePressed(FigCanvasEvent evt)

Description copied from interface: FigCanvasListener

Specified by:

keyReleased

public void keyReleased(java.awt.event.KeyEvent evt)

Specified by:

keyReleased in interface java.awt.event.KeyListener

keyPressed

public void keyPressed(java.awt.event.KeyEvent evt)

keyPressed: react to key-presses on the jfig editor frame and object canvas.

Currently, the following algorithm is used. We first check whether the user pressed the ESCAPE key. If so, the current command is canceled and replaced with the idle command.

Next, we check if the current command object is an instance of the CreateTextCommand. If so, the keypress is delivered to the 'keyPressed()' method of the CreateTextCommand. Please check the class documentation for details about this command class and possible subclasses.

Next, we check the keypress for Cursor-key events, which are used for object canvas panning operations. Note that panning via the keys is disabled during CreateTextCommands, because theses commands will intercept the corresponding cursor keys for their own purpose.

Finally, all other keypresses are silently ignored.

Specified by:

keyPressed in interface java.awt.event.KeyListener
