I changed the test script so it runs the code all at once, without waiting
for idle time. So the script doesn't draw anything until the very end, but
I don't care about the Tk stuff, only Vitalije's code:
def traverse_speed(x):
'''Traverse the entire tree.'''
g.cls()
if profile_redraw:
cProfile.runctx('traverse_speed_helper()',
globals(),
locals(),
'profile_stats', # 'profile-%s.out' % process_name
)
print('===== starting profile_stats')
p = pstats.Stats('profile_stats')
p.sort_stats('ncalls').print_stats(100)
# p.strip_dirs().
# .print_stats('leoDataModel.py', 50)
else:
traverse_speed_helper()
def traverse_speed_helper():
ltm.selectedPosition = ltm.positions[1]
ltm.expanded.clear()
ltm.invalidate_visual()
draw_tree(tree, ltm)
def tf(i):
if profile_redraw:
n_positions = len(ltm.positions)
n = min(1000, n_positions)
for i in range(n):
# From alt_right:
bw = G.body
gnx = ltm.select_node_right()
if gnx:
body = ltm.attrs[gnx][1]
bw.replace('1.0', 'end', body)
draw_tree(tree, ltm)
print('===== writing profile_stats')
p = pstats.Stats('profile_stats')
p.strip_dirs().sort_stats('tottime').print_stats(50)
# .print_stats('leoDataModel.py', 50)
else:
alt_right(None)
if i < 500 and i < n_positions:
tree.after_idle(tf, i + 1)
dt = datetime.datetime.utcnow() - t1
t = dt.seconds + 1e-6*dt.microseconds
G.log.insert('end -1 ch', '%s iterations in %6.2f sec\n'%(n,t))
t1 = datetime.datetime.utcnow()
tf(1)
G.app.bind_all('<Shift-F10>', traverse_speed)

Only the items "above the line" refer to Vitalije's code. It's remarkable
how few functions/methods are involved, and how little time they take. The
next step will be to study all these routines in detail.
