Maybe I should say Mozilla, not Google. Mozilla is the program on my computer.
Google is the search engine.

The code that I am using is:

if platform() = WIN32 then
  set_clip_text(clip_str) 
else
  set_text( txtClip, clip_str )
  select_all_text( txtClip )
  copy_text( txtClip )
  set_text( txtClip,"" )
end if

txtClip is a wxTextCtrl
Maybe there is a limit to how much data a wxTextCtrl can have.
Yeah? No?
I dunno.

It seems that there is a limit of 2047 in a single line wxTextCtrl under
GTK.  If you add the wxTE_MULTILINE style to txtClip, it should work.

I'm not sure why it's failing.  Here is the code I used to test:

-- clip.exu
-- created by wxIDE
without warning
include wxEuphoria.e
include wxText.e
include wxButton.e
include wxData.e

global constant
CopyTest = create( wxFrame, {0, -1, "Copy Test", 0, 0, 500, 400 }),
text1 = create( wxTextCtrl, {CopyTest, -1, "new_wxTextCtrl_1", 5, 27, 490, 50,
wxTE_MULTILINE }),
TxtCopy = create( wxButton, {CopyTest, -1, "Text Copy", 10, 195 }),
text2 = create( wxTextCtrl, {CopyTest, -1, "new_wxTextCtrl_2", 5, 130, 490, 50,
wxTE_MULTILINE}),
ClipCopy = create( wxButton, {CopyTest, -1, "Clip Copy", 10, 228 })

sequence test
constant len = 3000

test = ""
for i = 1 to len do
	test &= '0' + remainder( i, 10 )
end for
test &= '-' & sprint(len)
set_text( text1, test )
procedure clip( atom this, atom event_type, atom id, atom event )
	sequence text
	text = get_text_value( text1 )
	set_clip_text( text )
	set_text( text2, get_clip_text(  ) )
end procedure
set_event_handler( ClipCopy, -1, wxEVT_COMMAND_BUTTON_CLICKED,
routine_id("clip"))

procedure text( atom this, atom event_type, atom id, atom event )
	sequence text
	select_all_text( text1 )
	copy_text( text1 )
	set_text( text2, "" )
	paste_text( text2 )
end procedure
set_event_handler( TxtCopy, -1, wxEVT_COMMAND_BUTTON_CLICKED,
routine_id("text"))
wxMain( CopyTest )
-- end clip.exu
