Requests a redraw for the entire graph.

gog_view_queue_resize ()

void
gog_view_queue_resize (GogView *view);

Flags a view to have its size renegotiated; should be called when a model for some reason has a new size request. For example, when you change the size of a legend.

gog_view_render ()

                             GogViewRequisition const *available,
                             GogViewRequisition *req,
                             GogViewRequisition *min_req);

Computes additional requision in req which must be added to parent requisition, and minimum requisition in min_req which is minimum space for displaying all children.

gog_view_size_request ()

void
gog_view_size_request (GogView *view,
                       GogViewRequisition const *available,
                       GogViewRequisition *requisition);

Determines the desired size of a view.

Note, that the virtual method deviates slightly from this function. This function will zero requisition before calling the virtual method.

Remember that the size request is not necessarily the size a view will actually be allocated.
