WebContent: Start work on browser process separation :^) The "WebContent" service provides a very restricted instance of LibWeb running as an unprivileged user account. This will be used to implement process separation in Browser, among other things. This first cut of the service only spawns a single WebContent process when someone connects to /tmp/portal/webcontent. We will soon switch this over to spawning a new process for each connection. Since this feature is very immature, we'll be bringing it up inside of Demos/WebView as a separate demo program. Eventually this will become a reusable widget that anyone can embed and easily get out-of-process web content in their GUI. This is pretty, pretty cool! :^)

WebContent: Allow the WebContent process to trigger repaints After layout, we may want to repaint the page, so we now listen for the PageClient::page_did_invalidate() notification and use it to drive a client-side repaint. Note that an invalidation request from LibWeb makes a full roundtrip to the WebContent client and back since the client drives painting.

virtual void handle(const Messages::WebContentClient::DidInvalidateContentRect&) override;
WebContent: Notify client when web content selection changes The WebContentView widgets reacts to this by requesting a repaint.
2020-07-04 21:57:57 +03:00
virtual void handle(const Messages::WebContentClient::DidChangeSelection&) override;
WebContent: Basic scrolling support! :^) The WebContentView widget now inherits from GUI::ScrollableWidget and will pass its scroll offset over to the WebContent process as it's changing. This is not super efficient and can get a bit laggy, but it will do fine as an initial scrolling implementation. Just like the single-process Web::PageView widget, WebContentView also paints scrolled content by translating the Gfx::Painter.

virtual void handle(const Messages::WebContentClient::DidLayout&) override;
WebContent: Plumb title changes over to the WebContentView WebContentView now fires its on_title_change hook, like Web::PageView. We use this in the WebView test app to update the window title. :^)
2020-07-05 00:40:17 +03:00
virtual void handle(const Messages::WebContentClient::DidChangeTitle&) override;
WebContent: Plumb scroll-into-view requests from server to client The WebContentView widget will now be able to react to scroll-into-view requests from the WebContent process.
2020-07-05 16:43:43 +03:00
virtual void handle(const Messages::WebContentClient::DidRequestScrollIntoView&) override;
WebContent: Plumb hovered links from WebContent process over to widget Also add a little GUI::StatusBar to the demo app so we can see the hovered link URL's live. :^)

virtual void handle(const Messages::WebContentClient::DidHoverLink&) override;
virtual void handle(const Messages::WebContentClient::DidUnhoverLink&) override;
WebContent: Plumb link clicks to the WebContentView :^) You can now react to links being clicked via the on_link_click hook.

LibWeb: Make the WebContentView::on_load_start hook actually work :^)
2020-07-06 22:58:16 +03:00
virtual void handle(const Messages::WebContentClient::DidStartLoading&) override;
LibWeb: Make context menus work in WebContentView As usual, this was just a matter of plumbing the PageClient calls from the WebContent side over to the WebContentView side. :^)
