Color Mode

Determines how a Oracle Forms color palette will be loaded on your system. Each time you load, open, or create a form, Oracle Forms loads the Oracle Forms color palette into your current system color table. Because this system color table can handle only a limited number of colors at once, Oracle Forms may not be able to accurately modify multiple forms simultaneously if they use different color palettes. For this reason, use the Read Only - Shared option except when you are actively modifying the Oracle Forms color palette.

Color Mode options:

Editable Select Editable mode only when you want to change the Oracle Forms color palette. Once you have changed the color palette, return to Read Only - Shared mode. In Editable mode, each color has its own unique entry in the current system color table, and if there is no more room in the table, the color palette may refuse to load.

To change the Oracle Forms color palette:

  1. Change Color Mode to Editable and save your options (Edit | Preferences | General tab | Color Mode).
  2. Restart Oracle Forms.
  3. Use Edit | Layout Options | Color Palette to make changes to the color palette (only when the Layout Editor is open).
  4. Use Edit | Export | Color Palette to save the Oracle Forms color palette to a file (only when the Layout Editor is open).
  5. Change your options to use the new color file (Edit | Preferences | General tab | Color Palette).
  6. Change Color Mode back to Read Only - Shared and save your options.
  7. Restart Oracle Forms.
Read Only-Shared 
 
In Read Only - Shared mode, Oracle Forms maps duplicate colors to the same entry in the current system color table before appending new entries from your Oracle Forms color palette. Read Only - Shared will help you avoid the color flicker that can result when you switch between Oracle Forms color palettes and is the recommended setting for Color Mode unless you are modifying the palette.
 
Read Only-Private 
 
This option is provided for consistency with Graphics, and is not relevant for Oracle Forms. In Oracle Forms, it maps to Read Only - Shared.
