Development
Environment
Setup
Environment
- Effectively, you can only develop MPSGui inside Eclipse on lcls-builder.
- Check out the CVS module physics/mps/mpsgui into your workspace
- From now on, the root of project is referred to as $MPSGUI_ROOT
- You can use eco to checkout the package. The name of the module is mpsgui.
- Run ant to build the mpsgui and mpscud jar files.
- The mpsgui and mpscud scripts should use the jar files built in the jar folder.
Dependencies
For library paths, see the scripts $MPSGUI_ROOT/mpsgui or $MPSGUI_ROOT/mpscudbuild.xml file. Note that the dependent jar files are copied into the lib folder and are part of CVS. To update the jar files, run ant update_dependencies. This should copy the files from $PHYSICS_TOP on dev onto the lib folder. You can then commit these updated dependent jar files into CVS.
- ezJCA (version R0-0-10)
- javainterfaces (current version)
- MPS Config(current version)
- Oracle JDBC driver
- Sqlite JDBC driver
- SwingUtil (current version)
- jgoodies.jar can be added at runtime for the Matlab look & feel
- xal4lcls
- ext.jar (current version)
- xal.jar (current version)
Test
- Test using the mpsgui and mpscud scripts from the command line. This sets the Oracle Wallet environment variable and other EPICS variables.
Development
Major Recurring Tasks
- Previously, one had to check the live history in the MPS GUI HistoryViewer (and if empty, restart the MPS History Server)
Run inside Eclipse
...
- . However, now there is a CRON job that monitors this and will trigger alarms for the operators
Tips
- Find the Java field that contains the UI component that prompted your development (change the back-/foreground color, if not sure); then use Eclipse References (right-click menu) to find where the field is being used
Overview
Launch Scripts
mpsgui
- Located under $MPSGUI_ROOT, must be executable (chmod +x)
- Sets up the ORACLE Wallet and the log file
- Launches MPSGui using Plastic3DLookAndFeel from jgoodies
- byenti is a legacy system property that tells MPSGui to interpret bypass end times as absolute (or, if false, relative) times
mpscud
- Located under $MPSGUI_ROOT, must be executable (chmod +x)
- Sets up the Oracle Wallet and the log file
- Launches MPSGui in CUD mode using Plastic3DLookAndFeel from jgoodies
- Operators and Mike Z know details about the CUD mode
- byenti is a legacy system property that tells MPSGui to interpret bypass end times as absolute (or, if false, relative) times
Classes and Functions
User Interface
- The main user interface consists of 5 tabs: Summary, Faults, Logic, Ignore Logic, and History
- Each tab has a corresponding package under edu.stanford.slac.mpsgui.ui
- Classes in those packages are complex Swing components (mostly, JPanels and JTables)
- Each XYZPanel class under edu.stanford.slac.mpsgui.ui is a subclass of edu.stanford.slac.mpsgui.ui.AbstractPanel
- (Almost) every widget of the panel is stored in a field in the corresponding XYZPanel class, where XYZ is a descriptive string that explains what the panel shows
- The fields are public to allow registration of the listeners (however, it doesn't make sense to set them)
edu.stanford.slac.mpsgui.ui.AbstractPanel
- The root of all MpsGui XYZPanel classes
- Defines how widgets are created/added to its subclass
edu.stanford.slac.mpsgui.ui.MacroDetailsPanel

edu.stanford.slac.mpsgui.ui.MpsGuiTable
- The root of all MpsGui XYZTable classes

edu.stanford.slac.mpsgui.ui.SliderCachePanel
- Allows user to select a cached state
edu.stanford.slac.mpsgui.ui.edm.EDMPanel

edu.stanford.slac.mpsgui.ui.fault.CurrentFaultsPanel
- Not used anymore
edu.stanford.slac.mpsgui.ui.fault.EPICS/LinkNodeChannel/LinkNode/LinkProcessorFaultPanel
- Shows information specific to each fault type

edu.stanford.slac.mpsgui.controller.ignorelogic.IgnoreLogicViewer
- Controller for the "Ignore Logic" tab
- Monitors the state of ignoring macros (using MPS Config)

New States
- If the truth table's state can't be found in the Logic DB, make an alert panel that shows the truth table's name, the raw state value from the IOC:BSY0:MP01:TTBLST array, and a message saying "Send the above information to the controls group."
- Documentation
- Highlight new truth table state when selected

- Note that the mpsgui script redirects all logs to files elsewhere. During development and testing, it is often fruitful to have the logs on the console.
