# Test TE module.
|
||||
# Draw a window in which the user can type.
|
||||
# A minimal text editor.
|
||||
#
|
||||
# This test expects Win, Evt and FrameWork (and anything used by those)
|
||||
# to work.
|
||||
#
|
||||
# Actually, it is more a test of FrameWork by now....
|
||||
# To be done:
|
||||
# - Update viewrect after resize
|
||||
# - Handle horizontal scrollbar correctly
|
||||
# - Functionality: find, etc.
