commit 5ffd3b0506cc6acb618456ae276dd0238c1e3936 Author: Kamran Riaz Khan krkhan@inspirated.com Date: Wed Jun 1 17:06:27 2011 +0500
Next top-level item is dropped down in case right/left arrow keys are pressed on leaf submenus.
In order to let the controller redraw before next top-level item is dropped down, "menu keys" are calculated and returned back to the controller. The controller overrides its key so that menu is redrawn, redraws all other panels and sends back the "menu keys" to the new menu instance. This maintains the illusion of top-level drop-down moving right/left while screen is cleared and redrawn once in between. --- src/cli/controller.py | 6 +++++- src/cli/menu.py | 36 +++++++++++++++++++++++++++++++----- 2 files changed, 36 insertions(+), 6 deletions(-)
