PLANET EPL-1000 - Manual (Page 31)

3.3 Basic Operation of the GUI
As stated earlier, left-clicking the mouse on an entity in the Status Window shall cause an
associated tabbed dialog to appear in the Management Window. This dialog exposes
nearly the entire set of host interface commands associated with the managed entity. The
tabs are organized into roughly the same categories as the TK37XX Host Interface
document. And with few exceptions all of the panels function similarly.
GUI Controls
All controls in the GUI are derived from a common set of base classes and thus operate in
similar ways. Most panels include 1 or two buttons that invoke the GUI to perform various
transactions with the OLT. All such controls having the same basic function will also be
given the same label. For simplicity of understanding an explanation of each button type
appears bellow.
3.3.1 Apply Button
Most GUI panels manage only a single TK3721 Host Interface message. Every time the
panel is displayed the GUI will automatically query the OLT for the latest attributes by
issuing the appropriate Host Interface Message to the TK3721 firmware. If the query
operation is successful the panel will be updated with the latest values from the firmware.
As a general rule, when the panel is updated from a host interface message the associated
Apply button will be disabled to indicate that the values displayed are an accurate reflection
of the current state of the managed entity associated with the panel. If an error occurs the
Apply button will not be disabled indicating that the displayed values are not those of the
managed entity. Changing a GUI widgets value will cause the Apply button to be enabled
allowing the GUI operator to apply the new provisioning to the managed entity.
3.3.2 Refresh Button
Button’s labeled refresh are never disabled. The action associated with a Refresh button is
always to query the state of the associated attribute. The result of a successful Refresh
operation will be the same as if the panel is viewed for the first time. That is, the OLT will
query the managed entity associated with the panel, and if the operation completes the
Apply Button will be disabled.
