in the left side and then connect the tree view's adjustment to the
scrolled window's scroll bar.
+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)
