Implement this interface to handle events related to browser display state. The methods of this class will be called on the UI thread.

For an example of how to implement handler see cefpython.CreateBrowser(). For a list of all handler interfaces see API > Client handlers.

void OnAddressChange(Browser browser, Frame frame, string url)

Called when a frame's address has changed.

void OnTitleChange(Browser browser, string title)

Called when the page title changes.

bool OnTooltip(Browser browser, list& textOut)

Called when the browser is about to display a tooltip. textOut[0] contains the text that will be displayed in the tooltip. To handle the display of the tooltip yourself return true. Otherwise, you can optionally modify textOut[0] and then return false to allow the browser to display the tooltip. When window rendering is disabled the application is responsible for drawing tooltips and the return value is ignored.

void OnStatusMessage(Browser browser, string value)

Called when the browser receives a status message.

bool OnConsoleMessage(Browser browser, string message, string source, int line)

Called to display a console message. Return true to stop the message from being output to the console.

void OnAddressChange(Browser browser, Frame frame, string url)

Called when a frame's address has changed.

bool OnConsoleMessage(Browser browser, string message, string source, int line)

Called to display a console message. Return true to stop the message from being output to the console.

From testing it seems that this function gets called only for console.log(), console.warn(), console.error() and console.info(). You will not get all the messages that appear in developer tools console, see this thread: http://magpcss.org/ceforum/viewtopic.php?f=6&t=3347

void OnContentsSizeChange(Browser browser, Frame frame, int width, int height)

Called when the size of the content area has changed.

void OnFaviconUrlChange(Browser browser, string[]& icon_urls)

Not yet implemented in CEF Python.

void OnNavStateChange(Browser browser, bool canGoBack, bool canGoForward)

Called when the navigation state has changed.

void OnStatusMessage(Browser browser, string text, int statusType)

Called when the browser receives a status message. |text| contains the text that will be displayed in the status message and |statusType| indicates the status message type.

statusType can be one of:

cefpython.STATUSTYPE_TEXT

cefpython.STATUSTYPE_MOUSEOVER_URL
cefpython.STATUSTYPE_KEYBOARD_FOCUS_URL

bool OnTitleChange(Browser browser, string title)

Called when the page title changes. Implement this function to handle window titles for popup windows.

There is a default implementation of this function that sets titles for popup windows, otherwise they appeared on the taskbar with no title:

	cefpython.WindowUtils.SetTitle(browser, title)

	cefpython.WindowUtils.SetIcon(browser, "inherit")

Return True to call these two functions automatically, otherwise return False.

If you would like to implement it differently, have a look at the default implementation of SetTitle() & SetIcon() in WindowUtils:
../blob/master/cefpython/window_utils_win.pyx

bool OnTooltip(Browser browser, string &text[0])

Called when the browser is about to display a tooltip. |text| contains the text that will be displayed in the tooltip. To handle the display of the tooltip yourself return true. Otherwise, you can optionally modify |text| and then return false to allow the browser to display the tooltip.
