L-Series and FCS-18- Graphical User Interface User Manual
4.8 Status bar
The bottom edge of the main program window contains the status bar.
Information concerning the LSGUI program status is displayed here. The
status bar also contains a rectangular LED style indicator for the IEEE-488
interface. If this indicator is on (yellow), an L-Series power source is present
on the IEEE bus. When the LSGUI is in simulation mode, this LED will be off.
The LSGUI can be put in simulation mode even if an L-Series power source
is present on the bus. No commands will be send to it in simulation mode
however. Switching between connected mode and simulation mode is
accomplished through the “System-IEEE settings...” menu. (

4.9 Modal and Non-Modal windows
This section concerning modal and non-modal windows is intended for
users not familiar with Windows 3.1™.
Modal windows are those that when opened cause other tasks to be
suspended. Thus, program operation cannot continue until the user closes
the modal window that is presently open. The focus will remain on a modal
window as long as the program that opened the modal window is running.
Closing modal windows is commonly done by clicking on OK or Cancel
buttons. Dialog boxes that require users to make a choice are normally
modal. Many of the windows used in the LSGUI are modal as well. Only one
modal window can be open at any given time.
Non-modal windows are those than can remain open even if the focus is
moved to another window of the same program. Multiple non-modal windows
can thus be open at the same time. The LSGUI employs only three non-
modal windows :
1. Main program window
2. Steady State soft front panel
3. Measurement window.
