This lets the user zoom in and out on a web page using the View menu or
keyboard shortcuts. This does not implement zooming with ctrl+scroll.
In the future, it'd be nice to embed the zoom level display inside the
location toolbar. But to do that, we will need to invent our own custom
search field and all of the UI classes (controller, cell, etc.) to draw
the field. So for now, this places the zoom level display to the right
of the location toolbar.
This commit includes only fetching the DOM tree from the WebContent
process and displaying it in an NSOutlineView. The displayed tree
includes some basic styling (e.g. colors).
After moving to navigables, we started reusing the code that populates
session history entries with the srcdoc attribute value from iframes
in `Page::load_html()` for loading HTML.
This change addresses a crash in `determine_the_origin` which occurred
because this method expected the URL to be `about:srcdoc` if we also
provided HTML content (previously, it was the URL passed along with the
HTML content into `load_html()`).
This adds menu items to open an interactive JavaScript console for a web
page. This more or less mimics the Qt implementation of the console.
Hooks are included to tie the lifetime of the console window with the
tab it belongs to; if the tab is closed, the console window is closed.
The LadybirdWebView currently assumed it is viewed with a Tab instance.
This will not be true with the JavaScript console. This patch removes
this assumption by plumbing WebContent callbacks through a new protocol.
The Tab interface then implements this protocol.
This lets the user choose a color scheme which differs from the active
system theme. Upon changing the color scheme, the scheme is broadcast to
all active tabs, and will be used in new tabs.
This adds an alternative Ladybird chrome for macOS using the AppKit
framework. Just about everything needed for normal web browsing has
been implemented. This includes:
* Tabbed, scrollable navigation
* History navigation (back, forward, reload)
* Keyboard / mouse events
* Favicons
* Context menus
* Cookies
* Dialogs (alert, confirm, prompt)
* WebDriver support
This does not include debugging tools like the JavaScript console and
inspector, nor theme support.
The Qt chrome is still used by default. To use the AppKit chrome, set
the ENABLE_QT CMake option to OFF.
