- TITLE : FORM ATTRIBUTES IN PARADOX 2.0 VS. PARADOX 3.0
-
-
-
-
- In Paradox 2.0, all forms, whether created on a color or
- monochrome monitor, were saved with only Monochrome attributes.
- That means they have four basic attribute types: Normal,
- Intense, Reverse, and Intense-Reverse (which looks identical to
- Reverse on a mono monitor). Another attribute is Blink/NoBlink,
- which is toggled on or off for the four basic attributes, so
- there actually are eight basic mono attributes. The Blink
- attribute is always the same, regardless of monitor type or
- Paradox version. On a color monitor, the four mono attributes
- are directly translated at run time to specific default color
- combinations: white on dark blue for Normal, red on dark blue
- for Intense, black on light grey for Reverse, and dark grey on
- light grey for Intense-Reverse. These default combinations can
- only be changed through modifying the .CFG file (in Custom, or
- using the Colors script).
-
- In Paradox 3.0, forms created or saved are given two sets of
- attributes, Color and Mono, which are set using the Style/Color
- and Style/Mono selections in Forms/Design or Change. Mono
- settings still have the four basic attributes, but color settings
- have 128 attributes: sixteen foreground colors multiplied by
- eight background colors (actually, there are 256 color
- attributes, if you include the Blink/NoBlink bit).
-
- When you design a form in 3.0 on a color monitor, the color
- settings are saved as you see them (e.g. red on cyan gets the red
- on cyan attribute -- color attribute 52.) The mono settings are
- saved according to which color attributes are mapped to which
- mono attributes. The .CFG file determines which colors are
- mapped to which of the four monochrome styles, but the basic
- default settings (those which you see when you design a form with
- Style/Mono settings in 3.0 on a color monitor) are: black on
- grey for Normal, light blue on dark blue for Intense, black on
- cyan for Reverse, and white on cyan for Intense-Reverse.
-
- When you design a form in 3.0 on a mono monitor, the mono
- settings are saved according to how you defined them under
- Style/Mono (everything else is given the Normal attribute). The
- color settings by default are light grey on black for Normal, but
- they are not dependent on the Paradox configuration (.CFG file).

- TITLE : FORM ATTRIBUTES IN PARADOX 2.0 VS. PARADOX 3.0
-
-
-
-
- For an existing form, there are two areas where the attributes
- need to be translated: in form view and in the form spec
- (Forms/Change). In the latter case, saving the form (Do_it!) may
- alter the original attributes if the form was created on a
- different monitor type or Paradox version.
-
- When you view a color 3.0 form on a mono monitor in 3.0, the four
- color attributes will be translated to their corresponding mono
- attributes. All other color combinations will translate to
- Normal. The exceptions are the eight "bland" color attributes,
- (e.g. cyan on cyan, brown on brown, green on green, etc.). These
- eight attributes translate to black on black (attribute 0) on a
- mono monitor, so they will be invisible.
-
- When you save a color form in Paradox 3.0 on a mono monitor, you
- will wipe out all of the color attributes. All areas which were
- translated as mono Normal (which is practically every color
- attribute, except the three mapped to Reverse, Intense, and
- Intense-Reverse) will now be grey on black. Therefore, if you
- wish to create a form in 3.0 which will be used on both color and
- mono monitors, you should design and save it only on a color
- monitor.
-
- Paradox 3.0 on a color monitor will view and save Paradox 2.0
- mono forms by translating the mono attributes to their
- corresponding color attributes. This is why a 2.0 form which
- looks white on blue in 2.0 (the 2.0 default for mono Normal)
- looks black on grey in color 3.0 (the 3.0 default for mono style
- Normal).
