A theme is a collection of DDS conversion rules.  The theme is selected by its name from a dropdown list on the DDS Conversion Dialog.

While Profound UI is shipped with several prebuilt themes, it is often necessary to create a custom theme in order to modify the rules used by the conversion process.

Theme definitions are stored in the IFS directory /www/profoundui/htdocs/profoundui/userdata/custom/themes.  Each theme is defined in its own .js file containing a list of properties in JSON (JavaScript Object Notation) format.  To create a custom theme, copy an existing theme file to a new file name and then modify the JSON properties inside the file.  Make sure to modify the "name" property to reflect the new theme name.

The following properties are available:

  • name - the name of the theme; should generally be the same as the file name in which the theme is defined

  • input css class - the class applied to input elements (DDS field types "B" and "I") created by the DDS conversion

  • alt input css class - optional css class width for 132 wide screens

  • input css class 2 - the second class applied to input elements (DDS field types "B" and "I") created by the DDS conversion

  • constant css class - the class applied to elements created from DDS constants

  • altconstantcss class - optional css class width for 132 wide screens

  • output field css class - the class applied to output
    fields (DDS field type "O") and also to fields with DATE, TIME, USER, and SYSTEM keywords

  • alt output field css class - optional css class width for 132 wide screens

  • always set width - by default, output fields are not given a width so that the browser will automatically resize them to the size of the content within them.  If you set this option to true, a fixed width will be set on output fields during DDS conversion

  • css class prefix - the DDS conversion automatically maps DDS display attributes and colors to CSS classes with equivalent names, such as "HI" for High Intensity or "BLU" for Blue; this property allows you to prepend a prefix to each of the generated class names

  • top line color - optional property that specifies a color to assign to all header elements, or elements that appear on row 1 of a screen

  • top line css class - optional property that specifies a CSS class to assign to all header elements, or elements that appear on row 1 of a screen

  • default font family - optional font family to use on elements during the conversion; if not specified, the font family is picked up from the CSS

  • default font size - optional font size to use on elements during the conversion; if not specified, the font size is picked up from the CSS

  • default locale - sets the locale for date, time, or timestamp fields. Also used in Edit Code processing to assign appropriate formatting on field binding

  • left offset - offset from the left side of the screen in pixels for all converted elements; this allows you to create an area for a left sidebar with function key buttons

  • alt left offset - optional left offset width for 132 wide screens

  • top offset - offset from the top side of the screen in pixels for all converted elements

  • column width - determines how wide the space equivalent to a green-screen column should be in pixels

  • alt column width - optional column width for 132 wide screens.

  • row height - determines how tall the space equivalent to a green-screen row should be in pixels

  • alt row height - optional row height for 132 wide screens

  • extra textbox width - the width of textboxes generated by the conversion process is determined by multiplying the "column width" property by the character width of the green-screen field; this property allows you to add a few extra pixels to the textbox width 

  • auto arrange - specified the "auto arrange" property of a function key button, the default is true

  • button type - the type of button to use for function key buttons and for GUI DDS elements, such as those created from the PSHBTNFLD keyword; valid values are "button", "graphic button", "styled button", "css button", or "hyperlink"

  • button style - if  a styled button is used for the "button type" property, this specifies the button style to use 

  • button theme - if a css button is used, this specifies the button theme to use

  • buttons per row - number of buttons to arrange horizontally before a new row of buttons is created

  • add submit button - true or false value indicating whether a Submit button should be added to the screen; clicking the Submit button is similar to hitting the Enter key

  • help button - true or false value indicating whether the a Help button should be added to the screen and associated with the DDS HELP keywords; the default is true

  • submit button text - optional value to override the text that will appear on the Submit button; if not specified the word "Submit" will be used

  • buttons start at the top - determines if buttons are placed at the top of a screen going down or if they begin at the bottom of a screen

  • show fkey name - determines if the name of the function key (i.e. F1, F2, F3, etc.) shows on the button or hyperlink

    • header rows - this value determines the height of of the grid header in rows; the value can be specified as the number of rows,such as 0, 1, or 2; the value can also be set to "auto" to allow the DDS conversion to automatically determine the number of header rows based on constant fields present in the control record format or in the format returned by the function specified in the getHeaderFormat property; the value can also be specified as a custom function that receives control record and the subfile record as two separate parameters and returns the number of header rows

    • merge headings - this true or false value determines if heading fields are merged into the grid component itself using the grid's "column headings" property; merging the headings may provide a nicer look and may be easier to maintain; however, the positioning of the headings may not be accurate at first

    • set heading font - when set to true, the font properties or the "css class" property on heading output fields is set to match the standard grid headings; this is only done on heading output fields that were not merged or could not be merged into the grid heading

    • header field class - the css class to use on heading fields

    • message subfile class - the css class assigned to the grid when the grid represents a message subfile

    • show options as dropdown -  when set to true, the DDS conversion will look for option labels, such as 2=Change or 5=Display, and create a dropdown out of these options in the first column of the grid instead of using the standard textbox option field

    • show options as combo -  when set to true, the DDS conversion will look for option labels, such as 2=Change or 5=Display, and create a combo box out of these options in the first column of the grid instead of using the standard textbox option field

    • show options as context menu - when set to true, the DDS conversion will look for option labels, such as 2=Change or 5=Display and create a context menu.  You cannot have context menus and dropdowns or combo boxes, these options are mutually exclusive.

    •  

      • context menu css class - This option assigns a CSS class to the created menu widget, you will need to set up a CSS class to handle it.  This option is required.

      • context menu hover image - Optional property used to populate the “option hover image” property of the menus.

      • context menu option indent - Optional property used to populate the “menu option indent” property of the menus.

    • single row zoom - if set to true, the DDS conversion will enable the single row zoom feature on folding subfiles; single row zoom allows users to expand collapsed rows one at a time using a zoom icon

    • sortable - optional true or false property; enables the "sortable columns" feature on load-all subfiles; if omitted, true is assumed

    • find - optional true or false property; enables the "find option" feature on load-all subfiles; if omitted, true is assumed

    • getHeaderFormat - optional function that receives a subfile control record format name and returns the name of another record format that contains the headings for the subfile; intended for DDS code that stores subfile headings outside of the control record; ideally, there would be a predictable naming convention for such record formats

  • subfile option pattern - use a regular expression to match subfile options instead of the default mode, which looks for patterns like "someNum=some text". Example: /([A-Z0-9]{1,2}) ?(=) ?(\S+ *)/.

  • subfile option pattern greedy - set to false to prevent "subfile option pattern" from capturing text between matches. By default, the "subfile option pattern" algorithm looks for text between each match on a field and up to the end of a field; any found are added to the option text. For example, a field including the text, "9=Work with Print Status", would only get the text "Work" if "subfile option pattern greedy" is false, and the option text would get the entire "Work with Print Status" if this option is omitted or not false.

  • items - array of widgets, such as background panels, to add to each screen; each widget is an object of Visual Designer properties; you should at least specify the "id", "field type", "left", "top", "height", and "width" property; special properties "alt_width" and "alt_height" can specify the height and width for elements to be created on a screen that was originally a 132x27 character screen

Note: If a panel type is required that is not supported here, the type can be set to "panel", then in the add enhancements function the panel will appear in the format.items array and the properties can be changed as required.

    • panel style - specifies the panel style for the dialog or panel when the panel type is "panel"

    • header theme - optional header theme of a "css panel" dialog; if not specified, the default theme of "B - Blue" is used

    • body theme - optional body theme of a "css panel" dialog; if not specified, the default theme of "C - Gray" is used

    • has header - optional "has header" property of a "css panel"; valid values are "true" or "false"; if omitted, the css panel will by default have a header

    • header height - optional value to specify the height of a "css panel" header; if omitted, a default header height is used

    • button css class - optional CSS class of a function key button within the window; if omitted, the value is inherited from the top level "button css class" property

    • button tab index - optional tab index of a function key button within the window; if omitted, the value is inherited from the top level "button tab index" property

    • button left offset - optional left offset in pixels for function key buttons within the window

    • alt button left offset - optional left offset in pixels for function key buttons within the window, when the screen is a 132x27 screen 

    • button offset - top position offset from the bottom of the window in pixels for function key buttons created within the window

    • items - array of widgets to add to each window; each widget is an object of Visual Designer properties; you should at least specify the "id", "field type", "left", "top", "height", and "width" property

      The order in which the optional JavaScript functions are called, is as follows:

    1. For each record format, process field is called for each field, followed by add enhancements

    2. process fkey  called for each function key on all record formats, including btnSubmit if added

    3. grid enhancements

    4. last enhancements
