commit fbd07955c5376457a5a9ecc4e778dd4a9f97deb9 Author: Kamran Riaz Khan <krkhan(a)inspirated.com> Date: Mon May 30 01:33:22 2011 +0500 Added drop-down second level menus. Second level menus can now be brought down using the arrow key. Popup init is modified to support top and left gaps, setLeft() is added to Panel for left padding. Constructor arguments for Panel are left unchanged so that existing panel-using code isn't broken. --- src/cli/menu.py | 154 +++++++++++++++++++++++++++++++++++++++++++++++++---- src/cli/popups.py | 9 +++- src/util/panel.py | 18 ++++++- 3 files changed, 168 insertions(+), 13 deletions(-) diff --git a/src/cli/menu.py b/src/cli/menu.py index 71b56a4..69538e0 100644 --- a/src/cli/menu.py +++ b/src/cli/menu.py @@ -8,19 +8,40 @@ import cli.controller import popups from util import log, panel, uiTools, menuItem -TOPLEVEL = 0 +TOPLEVEL, SECONDLEVEL = range(2) class Menu(): """Displays a popup menu and sends keys to appropriate panels""" def __init__(self, item=None): DEFAULT_ROOT = menuItem.MenuItem(label="Root", children=( -

[arm/release] Replaced namedtuples with MenuItem instances, fixed left arrow key on

commit cf4ae8454debdf8a9ace9a4f4cc3e4536152d1dd Author: Kamran Riaz Khan <krkhan(a)inspirated.com> Date: Sun May 29 15:32:34 2011 +0500 Replaced namedtuples with MenuItem instances, fixed left arrow key on top level menu. The MenuItem class is added replacing LeafEntry and ParentEntry namedtuples. Replaced "entry" with "item" and defined the constant TOPLEVEL to improve readability. The scrolling calculations in _moveTopLevelLeft contained a bug, menus with large number of top items did not scroll to the end. Fixed by adding a check to see if we're "spilling" to left of first entry. --- src/cli/menu.py | 98 +++++++++++++++++++++++++------------------------- src/util/menuItem.py | 34 +++++++++++++++++ 2 files changed, 83 insertions(+), 49 deletions(-) diff --git a/src/cli/menu.py b/src/cli/menu.py index bedb98e..71b56a4 100644 --- a/src/cli/menu.py +++ b/src/cli/menu.py @@ -3,34 +3,32 @@ A drop-down menu for sending actions to panels.

The top-menu now displays "remaining" entries when right/left arrow keys are pressed enough times on shorter screens. Menus are no longer persistence and therefore are removed from Controller's init. Code review fixes: * Menu.draw() is renamed to Menu.showMenu(). * Overzealous map()s are replaced in favor of list comprehensions. * Popups are drawn through popup.add*() methods instead of drawing to windows directly. --- src/cli/controller.py | 12 ++----- src/cli/menu.py | 78 +++++++++++++++++++++++++++++++++++-------------- 2 files changed, 60 insertions(+), 30 deletions(-) diff --git a/src/cli/controller.py b/src/cli/controller.py index c506302..25c3051 100644 --- a/src/cli/controller.py +++ b/src/cli/controller.py @@ -81,7 +81,7 @@ def initController(stdscr, startTime): menu = cli.menu.Menu() # initializes the controller - ARM_CONTROLLER = Controller(stdscr, stickyPanels, pagePanels, menu) + ARM_CONTROLLER = Controller(stdscr, stickyPanels, pagePanels) # additional configuration for the graph panel graphPanel = ARM_CONTROLLER.getPanel("graph") @@ -135,7 +135,7 @@ class Controller: Tracks the global state of the interface """ - def __init__(self, stdscr, stickyPanels, pagePanels, menu): + def __init__(self, stdscr, stickyPanels, pagePanels): """ Creates a new controller instance.
