Created attachment 646595 [details] Layout view updates on every paint event For reference look at the attachment. All of the green lines are calls to LV_Update(), which is called on every paint event. Each tool should not be listening e.g. to paint events like this. The more tools we have the worse things will become. It makes much more sense to have a central notifier that will send out notifications to tools that care. e.g. The style panel is only interested in CSS changes to a specific node. Node centric tools should be able to register to listen to changes to a particular node. Some tools need to listen for mutation events. All tools should have access to a nodeDeleted notification. I would suggest that we create a central notifier that regularly sends changes to registered tools in order for them to be updated. Tools generally only need the latest event from a batch so we could be quite optimal with this. Paul may have been working on this. Do we have another bug logged?
I don't have anything really generic. Less generic work is being done here: - bug 765573 - bug 723904 - bug 762499
This is what I have been working on for bug 762499: +const PAGE_EVENTS = [ + "tabClose", + "tabHidden", + "tabVisible", +]; + +const WINDOW_EVENTS = [ + "close", + "DOMReady", + "ready", + "DOMNodeUpdate", + "DOMTreeUpdate", + "resize", + "paint", + "reflow", // bug 453650 +];
It is a shame that we can't have DOMNodeCSSUpdate but I suppose that would be difficult. Would you like this closed?
