Method Detail

setButtonNavigation

public void setButtonNavigation(int button,
                                int state)

Set the ability to use a given state within the handler for a specific mouse button (up to 3). This allows the caller to control exactly what states are allowed to be used and with which buttons. Note that it is quite legal to set all three buttons to the same navigation state

Parameters:

button - The mouse button value from MouseEvent

state - The navigation state to use for that button

setNavigationStateListener

public void setNavigationStateListener(NavigationStateListener l)

Set the listener for navigation state change notifications. By setting a value of null it will clear the currently set instance

Parameters:

l - The listener to use for change updates

mousePressed

public void mousePressed(java.awt.event.MouseEvent evt)

Process a mouse press and set the behavior running. This will cause the navigation state to be set depending on the mouse button pressed.

Parameters:

evt - The event that caused this method to be called

mouseDragged

public void mouseDragged(java.awt.event.MouseEvent evt)

Process a mouse drag event to change the current movement value from the previously set value to the new value

Parameters:

evt - The event that caused this method to be called

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent evt)

Process a mouse release to return all the values back to normal. This places all of the transforms back to identity and sets it as though the nothing had happened.

Parameters:

evt - The event that caused this method to be called
