IFrameHandler Interface |
Namespace: CefSharp
The IFrameHandler type exposes the following members.
Name | Description | |
---|---|---|
OnFrameAttached |
Called when a frame can begin routing commands to/from the associated
renderer process. Any commands that were queued have now been dispatched.
| |
OnFrameCreated |
Called when a new frame is created. This will be the first notification
that references frame. Any commands that require transport to the
associated renderer process (LoadRequest, SendProcessMessage, GetSource,
etc.) will be queued until OnFrameAttached is called for frame.
| |
OnFrameDetached |
Called when a frame loses its connection to the renderer process and will
be destroyed. Any pending or future commands will be discarded and
IsValid will now return false for frame. If called after
OnBeforeClose(IWebBrowser, IBrowser) during browser destruction then
IsValid will return false for browser.
| |
OnMainFrameChanged |
Called when the main frame changes due to one of the following:
- (a) initial browser creation
- (b) final browser destruction
- (c) cross-origin navigation
- (d) re-navigation after renderer process termination (due to crashes, etc).
oldFrame will be null and newFrame will be non-null when a main frame is assigned
to browser for the first time.
oldFrame will be non-null and newFrame will be null when a main frame is
removed from browser for the last time.
Both oldFrame and newFrame will be non-nullfor cross-origin
navigations or re-navigation after renderer process termination.
This method will be called after OnFrameCreated(IWebBrowser, IBrowser, IFrame) for newFrame and/or after
OnFrameDetached(IWebBrowser, IBrowser, IFrame) for oldFrame. If called after
OnBeforeClose(IWebBrowser, IBrowser) during browser destruction then
IsValid will return false for browser.
