Summary

Returns all child objects of port objects whose Text Color property complies with the Query.

Syntax

Object_TextColor(Parent) : Numeric_String
Object_TextColor(Parent) : Number

The Object_TextColor keyword can always be used in conjunction with a Numeric_String. It can alternatively be used in conjunction with a Number, but only when all other objects (which do not have a Text Color property) have been totally excluded by one or more preceding entries within the Query expression. Use entries in the expression such as Object_TextColor(Parent) <> '', or Object_TextColor(Parent) > ''. Alternatively, use an entry specifically targeting port objects, i.e. Object_ObjectKind(Parent) = 'Port'.

The color corresponding to a particular number can be deduced from the following relationship:

65536 * Blue + 256 * Green + Red

where the Blue, Green, and Red components each have a value between 0 and 255 (inclusive).

When the Object_TextColor keyword can be used in conjunction with a Number, it is possible to individually evaluate the values of each of the Text Color property's Blue, Green, and Red components, by using the following constructs:

  • Blue = Text Color Div 65536
  • Green = Text Color Div 256 Mod 256
  • Red = Text Color Mod 256

Example Usage

Object_TextColor(Parent) = '0'
Object_TextColor(Parent) <> '' && Object_TextColor(Parent) = 0
Returns all child objects of port objects whose Text Color property is 0 (which corresponds to values of Blue = 0, Green = 0, and Red = 0).

Object_TextColor(Parent) = '32896'
Object_TextColor(Parent) > '' && Object_TextColor(Parent) = 32896
Returns all child objects of port objects whose Text Color property is 32896 (which corresponds to values of Blue = 0, Green = 128, and Red = 128).

Object_TextColor(Parent) <> '16777215'
Returns all objects except child objects of port objects whose Text Color property is 16777215 (which corresponds to values of Blue = 255, Green = 255, and Red = 255).

Object_ObjectKind(Parent) = 'Port' && Object_TextColor(Parent) <> 16777215
Returns all child objects of port objects whose Text Color property is not 16777215.

Object_TextColor(Parent) > '' && Object_TextColor(Parent) Div 65536 >= 96 && Object_TextColor(Parent) Div 256 Mod 256 Between 64 And 192 && Object_TextColor(Parent) Mod 256 <= 128
Returns all child objects of port objects whose Text Color property is such that the Blue component has a value which is greater than or equal to 96, the Green component has a value which is greater than or equal to 64 and less than or equal to 192, and the Red component has a value which is less than or equal to 128.

Object_ObjectKind(Parent) = 'Port' && Object_TextColor(Parent) Mod 256 Between 64 And 192
Returns all child objects of port objects whose Text Color property's Red component has a value which is greater than or equal to 64 and less than or equal to 192.

Tips

  1. The Text Color property is defined for harness entry, note, port, sheet entry, and text frame objects, but only port objects can have children that are returnable by this expression.
