Color Implementation

Adding Color

You can specify background and foreground colors for screen fields and literal text when painting a screen table. You can type the name of the color directly into the field or a prompt screen appears with a list of valid colors.

Two TIBCO Object Service Broker tables and a shareable tool are used to implement the use of color in the Screen Definer. The tables @COLOURS and @SCREENCOLOURS are explained below.

Purpose of the @COLOURS Table

The @COLOURS table contains a listing of all the colors supported by TIBCO Object Service Broker, independent of the display device. Each color has a corresponding code that uniquely identifies it and a corresponding default code that maps to one of the eight base colors supported on most display devices.

Example

The following example illustrates of the @COLOURS table:

---

 

BROWSING TABLE : @COLOURS

SCROLL: P

Fields in the @COLOURS Table

The fields in the @COLOURS table contain the following information:

NAME	A listing of the colors supported on any device.
CODE	The global color code assigned to each color.
DEFAULTCODE	The default code assigned to each color. If a display device does not support a color, this code maps the unsupported color to one of the eight base colors supported on all devices.
COLORNAME	Lists the color names in mixed case with spaces.

Purpose of the @SCREENCOLOURS Table

The @SCREENCOLOURS table, parameterized by display device, lists the colors supported for a specific device (that is, 3270). The table has a minimum listing of eight colors. It also contains a field indicating which internal device code is substituted for a color that the device does not support.

Example

The following example illustrates the @SCREENCOLOURS table instances for a 3270 display device:

---

 

BROWSING TABLE : @SCREENCOLOURS(3270)

COMMAND ==>

SCROLL: P

_ 1 1

_ 2 2

_ 3 3

_ 7 7

_ 8 1

 

PFKEYS: 1=HELP 5=FIND NEXT 9=RECALL 18=EXCLUDE 13=PRINT 3=END 14=EXPAND

---

 

Fields in the @SCREENCOLOURS Table

The fields in the @SCREENCOLOURS table contain the following information:

GLOBALCODE	Color code listing for the global colors supported by the device. Always contains a minimum of eight base colors.
DEVICECODE	An internal device code used to map each color that is not supported on that device to a color that is supported. In the example, the color with a color code of 8 (BLACK), which is not supported on 3270 terminals, is mapped to the internal device code 1 (BLUE), which is supported.
