The Keyword Selection GUI

The Keyword Selection GUI is a small Tcl/Tk script run external to IDL which can be used to set all of UDF IDL Interface defined keywords. The advantage of this tool is that it it presents all of the keyword options in a straighforwrad manner without the need to either know the contents of or understand the workings of the UDF PIDF and VIDF. Once set the options can be saved and the save file imported directly into the IDL UDF Interface.

The primary usage of the Keyword Selection GUI is to set the return units of the UDF measurements. The tool allows both primary and secondary units to be selected for each measurement returned from a given UDF definitions.

The Keyword Selection GUI executable is UdfUnits and can be found in the $UDFTOOL_HOME/bin directory. To invoke the GUI execute:

UdfUnits [Menu File]

where [Menu File] is the name of the file to save the finalized keyword selections to. If no Menu File name is provided it will be assumed to be UDFUNITS.save If Menu File exists, it is assumed to have been created through a previous invocation of UdfUnits and the previous options will restored to the GUI menu. If you wish keep both the old options as well as the changed set, copy the original menu file to another file name and use that file as input to UdfUnits. If the file does not exist then an empty GUI menu is brought up.

Invoking UdfUnits with an non-existent menu file brings up the window:

The menus has four discrete regions. The uppermost set of three buttons defines the menu action options. This is followed by a row of 6 buttons which define various IDL processing options. The UDF definition is handled by the column of options running down the left-hand side of the menu. The open area to the right is where the buttons which give access to the various menus which display the UDF measurements and their units will appear.
