-TODO list on control flow view by Mathieu Desnoyers
-
-- Make "before hook" update process's info : it creates an inconsistency
- between state.c process table and process list. Waiting to see if
- state.c will take first event time as creation time or first schedule.
-
-
-- Split in process view and CPU ciew :
- - remove process 0 from the process list
- - add a new viewer to the module :
- - cfv.c -> new cpuctl.c : core of the view
- - eventhooks.c -> cpuhooks.c : draw cpu states
- - processlist.c -> cpulist.c
-
-- Check cfv for stability, modules load/unload, viewer start (many:3+), stop,
- memory leaks; standardize module unloading : in all cases they should call
- main window's API for viewer widget removal, and only then the memory should
- be released (from the call of the main window).
-
-- Add viewer selected signal (call main window's API function)
-- When viewing a big trace, use the fact that the drawing cannot be more
- precise than the amount of horizontal pixels it has : "jump" from one event
- to another, converting pixels to time in the trace. It will use efficiently
- the "saved state" functionnality of underlying state.c.
-
-- Modify widgets'organization so the time bar is not affected by scrolling :
- it may need to separate process list from the drawing area (not in a
- scrolled window anymore). The idea would be to use a scrolled window for
- the drawing area, put it in the right side of a hbox, put the tree view
- in the left side and then connect the tree view's adjustment to the
- scrolled window's scroll bar.
-
-- Modify icon, text and arc drawing so they are drawn only on top of the
- background. They will have to be drawn from the following event or from
- closure function in order to respect the priorities.
-
-Wish list
-
-- Tool bar for the viewer so many actions can be done on the screen.
-
-- Ability to select events with the mouse : in a "event selection mode", the
- mouse click would "redraw" the image virtually and select an event.
- (just like selectionGL in OpenGL).
-
-- Shown more events if wanted.
-
-- Use filter to show additionnal events. (do not filter schedule events!
- The filtering should be applied to the additionnal events only). Note that it
- require no change to filter : just do not make the filter apply on every
- incoming events in the viewer's hooks.
-
-- Add vertical lines showing control flow between processes : it may become
- confusing when working on multiple cpu.
-
-- Add a horizontal line showing the currently selected process. May be a
- light dotted line, similar to the current time line, but with a different
- color/pattern.
-
-- Add events customization window : make the user able to select the
- text/icon/line color/background color/dots linked with any kind of
- event. The framework is there, it must be completed. (the use of
- Attributes to call hooks for every event type comes from there)
