I want to get some infomation of entities when I use TCL/TK in GID. But the selection window is only valid when I invoke the list command.

The selection window is available not only for the list command, is also enabled when invoke other commands with multiple entities selection (layers send to, show labels, ..)

You can get information about entities from tcl with a ".central.s info list_entities" tcl command, for example:
.central.s info list_entities, for example, to list the lines 1 to 3, can use:

set out [.central.s info list_entities lines 1:3]

Note: can test easy a tcl command in the lower command line with a -np- prefix, for example, create some lines and write:
-np- WarnWinText [.central.s info list_entities lines 1:3]

The user can select entities with this tcl command:
::GidUtils::PickEntities type selectmode
# It returns the enties identifier numbers (for example 1 3 5:8 represents 1 3 5 6 7 8)
# type can be "Points" "Lines" "Surfaces" "Volumes" "Nodes" or "Elements"
# selectmode can be "single" or "multiple"

for example, test in the command line:
-np- WarnWinText "Selected line number [::GidUtils::PickEntities Lines single]"

Note: This tcl procedure can not be available for old GiD versions.
