# This is tricky and contains quite a few hacks:
# An entry contains 2 GdkWindows, one for the background and one for
# the text area. The normal one, on which the (normally white) background
# is drawn can be accessed through entry.window (after realization)
# The other window is the one where the cursor and the text is drawn upon,
# it's refered to as "text area" inside the GtkEntry code and it is called
# the same here. It can only be accessed through window.get_children()[0],
# since it's considered private to the entry.
#
# +-------------------------------------+

# |+----------------(2)----------------+|
# || |-- /-\ | || (2) entry.window (white)

# || | \-/ | || (3) text area (transparent)
# |+-----------------------------------+|
# |-------------------------------------| (4) cursor, black
# | |
# +-------------------------------------|
#
# So, now we want to put an icon in the edge:
# An earlier approached by Lorzeno drew the icon directly on the text area,
# which is not desired since if the text is using the whole width of the
# entry the icon will be drawn on top of the text.
# Now what we want to do is to resize the text area and create a
# new window upon which we can draw the icon.

# || |-- /-\ | || ||
# || |- | | | || (5) ||
# || | \-/ | || ||
# |+----------------------------++-----+|
# |-------------------------------------|
# | |
# +-------------------------------------+
#
# When resizing the text area the cursor and text is not moved into the
# correct position, it'll still be off by the width of the icon window
# To fix this we need to call a private function, gtk_entry_recompute,
# a workaround is to call set_visiblity() which calls recompute()
# internally.
