The documentation to the ggexclude.cfg-File states that you cannot access items, that are part of a collection:
A special case are collections in forms (like TDBGridColumns in a
TDBGrid [...]) You can exclude only the whole collection, but not
certain properties of a collection.
So the workaround would be to exclude the whole Columns-Collection:
TDBGrid.Columns
But this way you will lose Title.Caption too.
The only other workaround I see, would be to modify dxgettext. The following would be nice to have IMHO:
[always-exclude-property]
FieldName
Edit: I wanted to link to the ggexclude.cfg-documentation, but I cannot find it online right now. So I feel free to post the documentation as it is saved in my own ggexclude.cfg-file - but without any guarantee:
# Text in square brackets, like "[exclude-dir]", is called a "section".
# Each line that is not empty, not a comment and not a section holds
# exactly 1 "value".
# All lines below a section are scanned for values belonging to that
# section until the next section starts. You can use the same section
# several times. It will all be added up.
[exclude-dir]
# This section prevents a whole folder and all it's subfolder from being scanned.
# Each value is exactly one folder. On Windows, it's not case-sensitive.
# You can use relative or absolute paths. No wildcards allowed.
# example:
# subfolder
# these are valid values as well:
# another\folder
# another\folder\
# Windows: D:\yet\another\folder
# Linux: /home/zaphod/projects/subfolder/
# You don't have to worry about the path delimiters, both "/" and "\"
# can be used. They are converted to "/" internally
[exclude-file]
# This section prevents a whole file from being scanned.
# Each value is exactly one file. On Windows, it's not case-sensitive.
# You can use relative or absolute paths. Wildcards allowed.
# example:
# Unit4.dfm
# Using the wildcard ".*" for a file extension means that the following
# matching Delphi-files will be excluded: dfm, xfm, pas, inc, rc, dpr:
# Unit5.*
# If Unit3 is already excluded by the [exclude-dir] above, because it
# is located in a subfolder of "subfolder", listing it here therefore
# has not further effect:
# subfolder\subfolder\Unit3.dfm
# you can use absolute paths as well, like this:
# on Windows: D:\test\Unit.pas
# on Linux: /home/zaphod/projects/MainForm.*
[exclude-form-class-property]
# This section prevents a certain property of a class to
# be excluded from scanning in all forms of the folder and subfolders
# where "ggexclude.cfg" is located.
# The format for a value is "Classname.Properyname". It's not case-sensitive. No wildcards allowed.
# Classname is obvious, the propertyname has to be written the way it
# is written in the form file. If you're in doubt about how a certain property
# has to be stored here, just copy and paste the line from the DFM file here and
# put the classname before that.
# For simple strings the property name is one word:
# TLabel.Caption
# ...and for TStrings it's like this:
# TListbox.Items.Strings
# TMemo.Lines.Strings
# TQuery.SQL.Strings
# TEdit is listed in the [exclude-form-class]-section below which means
# that the whole class will be excluded. Listing TEdit.Text here therefore
# has no further effect
# TEdit.Text
# A special case are collections in forms (like TDBGridColumns in a TDBGrid,
# TParams in a TQuery or TActionManager.ActionBars). You can exclude only
# the whole collection, but not certain properties of a collection. That
# means as well that in the case of nested collections (see TActionManager.ActionBars
# in the sample unit "nestedcollections.dfm"), everything that appears below
# the collection with the highest level will be ignored.
# Note that some collections are saved with another name than their propertyname.
# For example: "TQuery.Params" will be saved as "ParamData" in the form file.
# TQuery.ParamData
# TDBGrid.Columns
# TActionManager.ActionBars
# these lines won't work:
# TDBGrid.Columns.Title.Caption
# TActionManager.ActionBars.ContextItems
# ("ContextItems" is a nested collection, which can hold another nested collection and so on)
[exclude-form-class]
# This section prevents a whole class to
# be excluded from scanning in all forms of the folder and subfolders
# where "ggexclude.cfg" is located.
# The format for a value is just "Classname". It's not case-sensitive.
# A wildcard "*" can be used optionally.
# A special case are collections, see [exclude-form-class-property] for that
# Here, everything of TEdit in DFM/XFM-files will be ignored. Remember:
# other classes derived from TEdit have to listed seperatly in order to
# exclude their properties as well. Inheritance is not recognized by dxgettext:
# TEdit
# Visual containers like TPanel or TScrollbox have to be treated slightly different.
# If you have a TPanel with a TLabel on it, writing "TPanel" would only
# exclude the properties of TPanel itself. If you want to exclude
# everything contained in a TPanel, use the wildcard "*" at the end, like this:
# TPanel*
# The following only excludes the properties of TScrollbox itself, but not the controls
# contained in Scrollboxes (except other classes explicitly listed here, like
# TEdit above):
# TScrollbox
[exclude-form-instance]
# This section prevents a certain instance (=object) of a class in a certain form file to
# be excluded from scanning.
# Each value is exactly one file with one instance. The format is
# "filename:instancename". On Windows, the "filename" part is not
# case-sensitive. You can use relative or absolute paths.
# Note that if the instance is something like a container or menu,
# everything belonging to that will be excluded.
# Note also that a frame on a form might contain a component with the
# same name as a component on the form. They would both be excluded.
# Unit6.dfm:Popupmenu
# Unit6.dfm:Label5
