Commands

• File

  • Open

    Displays the open file dialog, where you can select a document to be opened. You can either open .class or .jar documents. If you select multiple files, they will all be opened in the same window, as will be the classes in a .jar archive.
    Note: .jar support depends on a 'jar.exe' program, whose location you can specify in the Settings:JAR menu. The jar.exe will be called exactly like this:
    <full path to jar.exe> vxf <full name of .jar file >. This should extract all the .class files from the .jar to the same directory, from where JUG tries to read them.
    The 'vxf' option works with the JRE 1.3.0_02 from sun.com. Let me know if this should be more customizable or you know of a better solution. (If I find some free decoder lib for .jar files I will add native support for JAR to JUG of course.)

  • Save

    Displays the save file dialog, where you can select the filename for a document to be saved as. You can either save the diagrams as .emf or .eps for now. Note however, that there is only direct support for the .emf format. To save as .eps, you need an eps printer driver. (Available for free from Adobe for example) You can select the printer driver to use in the Settings Menu. The saved document will contain exactly what is displayed in the main window, including the margin. See the format menu for a way to disable the margin.
    One weak point of .eps files is the handling of the bounding box. Where you can just pass the coordinates to emf files which are directly supported, with eps the bounding box is first passed to the printer driver. And the printer might decide to just print on a default paper format, like <letter> or <A4> (Normally it should work however). If you happen to know of a free eps printer driver which could be included with JAR, let me know. (Upon request, future versions will correct the bounding box entry in .eps files before writing them to disk, to work around bad printer behaviour.)

  • Close

    Closes the active document, without saving. Note, that you currently can't change anything in the diagram, so there is no point saving it anyway. 'Save' just exports it to .emf / .eps.

  • Print

    Opens a dialog where you can print the active document.

  • Quit

    Closes all open documents without saving, and exits the application.

• Format

  • Font

    Let's you specify the font and color in which to display text.

  • Highlighted Font-Color

    Select the color for highlighted text here.

  • Back Color

    Selects the color for the class diagram background.

  • Frame Color

    Selects the color for the frame drawn around classes, and for the ruler lines in the class diagrams.

  • Margin

    Turns the margin on or off.

• View

  Tell the program what information will be included in the diagrams.

  • Show Type

    Shows the types of properties and methods in the class.

  • Show Private

    Includes private fields in the class diagram.

  • Show Protected

    Includes protected fields in the class diagram.

  • Show Special

    Includes any special information found in the class file. I don't know much .java, but this displays the constructors (called <init>) and some other generated methods, recognized by their names starting with '$' (?)
    Anyone who can enlighten me on this - and knows better ways to use (or hide) that information, tell me.

• Settings

  • EPS

    Before saving to the .eps format, you should select the eps printer driver to use here. Otherwise, you will just receive an error message.

  • JAR

    Before attempting to load .jar files, you tell the JUG application the location of jar.exe here. Ideally, this should be autodetected. (or better even, if there is any free .jar library out there, native support could be added. (See the Open Command.)
