The color is output in a string parameter, in the format accepted by cxParamColorFloatGet. Names selected from the scrolling list are not changed, so that they are more descriptive. If the color is changed by the interactive editor, the "RGB:" format is used for precision.
By default, the interactive editor requires that the "Accept" button be pressed before the color is output. The user may put the editor into "Simultaneous" mode, so that each mouse movement generates an output. This mode is discouraged, because of the large number of module firings it may cause.
Note: this module is not available in all implementations of IRIS Explorer, in particular not in the Windows NT version.
Port: Color Name
Type: Scroll List
The color names present in the X rgb database (see showrgb(1)).
Selecting a name
causes the interactive editor's current color to be set to the RGB
value of this name in the database. Note that there are often several
names with the same RGB values, due to spelling variations and white
space removal.
Port: Color Editor
Type: Button
This invokes the interactive color editor. The editor window may be
dismissed to save screen space. Pressing this button reveals the
color editor. The editor's internal state is preserved.
Port: Color Window
Type: Drawing Area
The color selected is displayed behind the "Color Editor" button.
Port: Color
Type: Parameter
The selected color is output in the format described in
cxParamColorFloatGet.
It might make sense to separate the name database and interactive editor into two modules. Internal logic is complicated by the fact that two interactors are trying to set the same value, and the editor value cannot always be mapped into a database value. This would make it possible to set the initial value from the database, then modify it with the editor without loosing the original database selecting. The database module could then quantize input colors to the "closest" database color, if desired.
