Chromium browser user interface -

WebUIConfig s are created at startup when factories are registered, so should be lightweight. A WebUIController is the brains of the operation, and is responsible for application-specific logic, setting up translations and resources, creating message handlers, and potentially responding to requests dynamically.

In complex pages, logic is often split across multiple WebUIMessageHandler s instead of solely in the controller for organizational benefits. A WebUIController is owned by a WebUI , and is created and set on an existing WebUI when the corresponding WebUIConfig is found in the map matching the URL, or when the correct controller is determined via URL inspection in ChromeWebUIControllerFactory.

The WebUIDataSource class provides a place for data to live for WebUI pages. For more about each of the methods called on WebUIDataSource and the utility method that performs additional configuration, see DataSources and WebUIDataSourceUtils. Because some pages have many messages or share code that sends messages, message handling is often split into discrete classes called WebUIMessageHandler s.

These handlers respond to specific invocations from JavaScript. This is a factory method required to create and add a WebUIDataSource. The first argument to Create is the browser context. The second argument is typically the host name of the page.

The caller does not own the result. Additionally, calling CreateAndAdd will overwrite any existing data source with the same name. grd or. getString or getStringF.

Many Web UI data sources need to be set up with a large number of localized strings. Instead of repeatedly calling AddLocalizedString , create an array of all the strings and use AddLocalizedStrings :.

grdp file , adds a resource to the UI with the specified path. Similar to the localized strings, many Web UIs need to add a large number of resource paths.

In this case, use AddResourcePaths to replace repeated calls to AddResourcePath. The same method can be leveraged for cases that directly use constants defined by autogenerated grit resources map header files.

All the resources in this resource map can be added as follows:. Often a page needs to know whether a feature is enabled. This is a good use case for WebUIDataSource::AddBoolean. Then, in the Javascript, one can write code like this:.

If you really want or need to use AddBoolean for a dynamic value, make sure to call WebUIDataSource::Update when the value changes.

This method performs common configuration tasks on a data source for a Web UI that uses JS modules. When creating a Web UI that uses JS modules, use this utility instead of duplicating the configuration steps it performs elsewhere.

Specific setup steps include:. To use Mojo, you will need to:. Mojo interfaces are declared in mojom files. For example:. The WebUIController class should inherit from ui::MojoWebUIController and from the PageHandlerFactory class defined in the mojom file.

The callbackRouter PageCallbackRouter can be used to add listeners for asynchronous events sent from the browser. The handler PageHandlerRemote can be used to send messages from the renderer to the browser. For interface methods that require a browser response, calling the method returns a promise.

The promise will be resolved with the response from the browser. send pattern. A tab that has been used for settings UI may be reloaded, or may navigate to an external origin.

In the former case, the callbacks will occur when the Javascript doesn't expect them. In the latter case, sensitive information may be delivered to an untrusted origin. Therefore each message handler maintains a boolean that describes whether delivering callbacks to Javascript is currently appropriate.

This boolean is set by calling AllowJavascript , which should be done when handling a call from Javascript, because that indicates that the page is ready for the subsequent callback. See design doc. If the tab navigates or reloads, DisallowJavascript is called to clear the flag.

If false, then the callback must be dropped. When the flag is false, calling ResolveJavascriptCallback will crash.

Also beware of ABA issues: Consider the case where an asynchronous operation is started, the settings page is reloaded, and the user triggers another operation using the original message handler. We could add a callback handler to perform integer arithmetic for us. new ChromeWebUIDataSource chrome::kChromeUIHelloWorldHost ;.

virtual ~HelloWorldUI ;. addResult", result ;. function initialize {. send 'addNumbers', [2, 2] ;. return {. initialize: initialize,. You'll notice that the call is asynchronous. Once you've created a WebUI resource following the above instructions, there are two changes necessary to make it a dialog.

You must subclass the HtmlDialogUI class instead of ChromeWebUI and create an HtmlDialogUIDelegate class which will be responsible for running the dialog. Instead of subclassing the ChromeWebUI class as above you will need an instance of HtmlDialogUI.

Create an HtmlDialogUIDelegate class which is used to instantiate the dialog. For brevity each of these functions are stubbed out with the minimal code possible.

pragma once. As you may have guessed, the HtmlDialogUIDelegate::GetDialogArgs function call is used for passing arguments to a dialog page. For example, if we wanted to have a custom message displayed to the user depending on some argument known only at dialog creation we could pass that argument in during construction, return it from GetDialogArgs, and access it in Javascript from chrome.

dialogArguments as follows:. std::string HelloWorldDialog::GetDialogArgs const {. getElementsByTagName 'p' [0]. In practice you will probably be passing structured data to your WebUI for which you can use the class base::JSONWriter to produce a JSON string which can be parsed in javascript using JSON.

Much of the early work in this area concentrated on shrinking the size of WebKit , the image resizer, and the Android build system. Other changes in were GPU acceleration on all pages, adding support for the new Web Audio API , and the Google Native Client NaCl which permits native code supplied by third parties as platform-neutral binaries to be securely executed within the browser itself.

The sync service added for Google Chrome in could also be used by Chromium builds. In , Chromium's modified WebKit rendering engine was officially forked as the Blink engine.

Other changes in were the ability to reset user profiles and new browser extension APIs. Version 67 added the security benefit of per- process website isolation. Starting in March , the Google Chrome sync service can no longer be used by Chromium builds. In addition to Google Chrome, many other notable web browsers have been based on the Chromium code.

Significant portions of the Chromium code are used by some application frameworks. Notable examples are Electron , the Chromium Embedded Framework , and the Qt WebEngine.
