Method Detail

getModifiedObjects

public FigObject[] getModifiedObjects()

return an array-wrapped reference to the text object (to be) resized by this command. The text object reference may be null.

public void execute()

Description copied from class: Command

Try to undo this command as far as possible. Don't try to undo() a command that has never been execute()d before. This method is empty for class Command.

undo in class Command

mousePressed

public void mousePressed(FigCanvasEvent evt)

select the object to move (at position startPoint) and its new position (endPoint).

To allow for selection of stacked objects at/near startPoint, we use the following algorithm: First, we simply use editor.findObjectAt() to find the topmost object (if any) at or near startPoint. If an object is found, its corners are highlighted, while all other object markers are removed.

If the user clicks again on/near startPoint - and with the SHIFT-key hold down, the editor.findNextObjectAt() method is called repeatedly, to find the next objects.

The selected object is moved as soon as the users clicks on a position different from the startPoint.

Overrides:

mousePressed in class Command
