public abstract class Gui extends JPanel
Base class for GUI code generated by Compiler.

Realizes fundamental methods for displaying and editing option arguments. These methods will partly be called by the generated code, partly by user code (for initialization and final checking), partly by the swing ui-process autonomously.

The layout of the control panel itself (inner panel, without interactive buttons) is 
  JPanel --- GridBagLayout
  |
  |  TTLabel       (=abbrev-string)
  |  JLabel        (= "/")
  |  TTLabel       (=name-string)
  |  JLabel        (= ":")
  |  JPanel  ("growing group") //  has "MultiLineFlowLayout"
  |  |  Field_int
  |  |  Field_bool
  |  |  
  |  |  Handles
  |  |  | TTHandle
  |  |  | TTHandle
  |  |  | TTHandle
  |  |  Collection ("growing group")
  |  |  | Field_int
  |  |  | Field_string
  |  |  Handles
  |  |  | ...
  |  |  Collection
  |  |  | ...
  |  |  Handles
  |  |  | ...
  |
  |  TTLabel    // next line
  |  JLabel

All text fields, labels, tooltips etc are multilingual. The translations for the model-independent texts (e.g. "input integer" / "ganze Zahl eingeben") are fixed and contained in Messages.
Translations for further languages can be added to the value of field messages.

The documentation texts for option names and parameter fields are in the Model, namely Model.descriptions.
This class can be used in varying contexts (e.g. integrated in card layouts). But it also offers a standard way for modification and confirmation by the user by +++ editGraphically(String,JPanel,Dimension,String,String[],String[])

  • Field Details

    • errorstate

      protected boolean errorstate
      Is set/reset by the InputVerifier methods of all fields with syntax, and read by the handle buttons, to make them inactive as long as a widget input error is pending.

    • errorkey

      protected String errorkey
      The un-translated error message, i.e. the key into the translation map.

    • errorcomponent

      @Opt protected @Opt JComponent errorcomponent

    • messagePane

      @Opt protected @Opt JLabel messagePane

    • updateLanguage

      public void updateLanguage()
      Signals from outside that the language preferences (in particular the first language) have changed.
      Tooltips will be affected the next time they pop-up (language change is passive, rendering inquires text actively.)

      Button texts will be changed immediately (language change is active).

    • populate

      protected abstract void populate()
      Callback function, overriden by generated code. Inserts the different labels and input widgets for options and their arguments into this. Does not yet fill in values.

    • translate_description

      @Opt protected @Opt String translate_description(String key)
      Translate a key into the application specific descriptions. (NOT into the standard generic messages.) The result can be in a different language, if the key has not been translated in preferred language. In this case the result is enclosed in brackets.

    • make_label

      protected void make_label(@Opt @Opt String name, @Opt @Opt String abbrev, List<Component> allcomponents)
      Called by Generated code. Creates labels with name and/or abbrev and a panel for the value widgets ("growingGroup") and puts them into top level grid bag. Not both of "name" and "abbrev" may be ==null.

    • getInitialWidthOfValuesPanel

    • set_error_on

      protected void set_error_on(JComponent comp, String mkey)
      Reflect an illegal input syntax in the gui. The offending field is coloured backgroundColor_error (=normally red); all focus shifts (internal to the GUI) away from it are hindered by in-activating all sibling inputs; a multi-lingual error text is shown in the dedicated field messagePane.

    • set_error_on

      protected void set_error_on(String mkey)

      public static void updatePos(JPanel container, boolean isStar)
      Re-assigns the numbering of the groups, which appears in the title, and makes certain buttons invisible in the "Handles" groups at both ends.

      ASSUME only called when container does contain Handles. Then the last component (count-1) is a Handle, and the next-to-last (count-2) is not!

      Each "middle" handle has all three actions; the "last" has only "add"; The "first" has "add" and (possibly) "delete". The structure of the JPanel is 
            panel "pp"                                               count=14

      (Currently only used for the title etc. of a FileChooser.)
      res[0]:String = longest parameter name
      res[1]:int 0..n = repetition group number, or -1 for the non-repeting prefix
      res[2]:int 0..n = parameter no in that group, or -1 for single member

      public static void model2view_repeting(JPanel container, List models)
      Called by the generated code for data transfer. Un-zips the list of components in "container" into Collections and Handles, then calls "model2view" for all objects in "models", possibly after creating new view Collections via "doplus()" of any (/of the first) Gui.Handles.

      Called by the generated code for data transfer. Un-zips the list of components in "container" into Collections and Handles, then calls "view2model" for all Collections, possibly after creating new model instances via "makeModelInstance()" of any (/of the first) Gui.Handles.

    • editGraphically

      public void editGraphically(@Opt @Opt String titleText, @Opt @Opt JPanel titleGraphic, @Opt @Opt Dimension innerArea, String lang, String[] buttonLabels, String[] cancelButtons)
      Interactive execution of the gui panel, very simple style.
      Only one language, no Menus. The method opens a top-level (dialog-)window with the option pane (as generated by the compiler), plus additional buttons plus an error message line. It lets the user play with the widgets until one of the buttons is pressed (and currently no syntax error pending!) Then buttonAction(String) is called, with the untranslated label key.
      Parameters:
      titleText - text on top of the window
      titleGraphic - included above the parameters' panel
      innerArea - if set, default size of parameters' panel
      lang - the initial language
      buttonLabels - the keys of the action buttons (the presented texts are translations from the current muli configuration.)
      cancelButtons - keys of buttons which are active during input errors

    • buttonAction

      protected void buttonAction(String key)
