attachToOL

void attachToOL(objRef,refreshId)

Attaches the control for this button to OpenLayers and add it to the buttonBar. When this method is called, everything of the OL map is available.

Parameters:
objRef - Reference to this object.
control - to add.

buttonInit

void buttonInit(objRef)

Set the target context for the button, initialise the buttonBars array in the context document and add a listener to the target model for adding controls to the OL map as soon as the map is initialized.

Parameters:
objRef - Reference to this object.

doAction

void doAction()

Override this in buttons which inherit from this object to carry out the action. This is the function that will be called either when the button is selected via the select() method or on a mouseup event if there is an associated mouseHandler property in config.

doSelect

void doSelect(objRef, selected)

Method overriden by subclasses

Parameters:
objRef - Reference to this object.
selected - True when selected, false when deselected.

getButtonClass

Object getButtonClass(objRef, state)

Parameters:
objRef - Reference to this object.
state - 'Active' or 'Inactive' (case sensitive!)
