WebView2 interfaces and types

Lists the WebView2 interfaces, enumerations and structures that sys/win/webview2 declares.

CWebView2 wraps the everyday calls. Everything else WebView2 offers is reached through the interfaces listed here: GetWebViewPtr, GetControllerPtr and GetEnvironmentPtr return the three a program starts from.

Calling a method. Each interface is a type whose methods are called directly with ->, as in pCore->Navigate( "https://example.com/" ). Every method returns an HRESULT, S_OK on success; values come back through a pointer argument. A property is a get_ method that reads it and, when it can be changed, a put_ method that sets it. Yes-or-no values are LONGs (WINBOOL): TRUE or FALSE.

Example

dim pCore as ICoreWebView2 ptr = CWebView2Ptr( hwnd )->GetWebViewPtr()
dim pwszUri as LPWSTR
if pCore->get_Source( @pwszUri ) = S_OK then
    dim uri as ustring = *pwszUri
    CoTaskMemFree( pwszUri )
    print uri
end if

What must be released. A string a method returns (an LPWSTR written through an LPWSTR ptr) is the caller's: free it with CoTaskMemFree. An interface a method returns carries a reference: call its Release when done. The pointers from GetWebViewPtr and the other two CWebView2 getters, and the sender and args a handler receives, are borrowed: do not release them, and call AddRef on one to keep it.

Later versions. ICoreWebView2_2 to ICoreWebView2_28, ICoreWebView2Controller2 and the other names ending in a number each extend the one before and add only the members listed. Ask the object for the version you need with QueryInterface and its IID_ variable; on a WebView2 runtime too old to have it, the call fails with E_NOINTERFACE.

Example

dim p8 as ICoreWebView2_8 ptr
if CWebView2Ptr( hwnd )->GetWebViewPtr()->QueryInterface( @IID_ICoreWebView2_8, cast( any ptr ptr, @p8 ) ) = S_OK then
    p8->put_IsMuted( TRUE )
    p8->Release()
end if

Names. Each interface name is an alias of a type with the same name and a trailing underscore, ICoreWebView2 of ICoreWebView2_, which extends ComUnknown (the IUnknown methods QueryInterface, AddRef, Release) or the interface it is a later version of. Programs use the name without the underscore. Every interface also has its identifier as a shared GUID named IID_ and the interface name: IID_ICoreWebView2_8.

Callbacks. The handler interfaces, and the options interfaces marked as supplied by the program, are implemented by the program, not by WebView2. For the common events, extend one of the classes on WebView2 event handlers.

Importing

#import "sys/win"
#import "sys/win/webview2"
using win, webview2

Example

A web view whose context menu and status bar are turned off through its settings interface, and whose sound is muted through ICoreWebView2_8. Like every WebView2 program it needs WebView2Loader.dll beside the executable; the WebView2 examples in the toolchain's examples/win64/ folder come with one.

#import "sys/win"
#import "sys/win/gui"
#import "sys/win/webview2"
using win, gui, webview2
