> The dynamic part starts with the constructor of the viewer. It is called by the
main window when the corresponding button or menu item is selected. See
h_guicontrolflow() from control flow viewer eventhooks.c for an example. It does
basic connexion to the tab's events available : time window change notification,
current time notification, redraw notification, continue notification. All these
function should be implemented in your viewer if you want the data you shown to
be synchronised with the main window and the other viewers. It also calls the
background computation, which will be discussed in the next section.
</P
><P
> This is also at this point that the viewer does create it's own memory footprint
: its inner structure. This structure will have to be passed as hook_data to
each function registered by the viewer : this is what makes the functions
"belong" to this instance of the viewer.
