Methods defined here:<br>
<dl><dt><a name="Tab-Activate"><strong>Activate</strong></a>(self)</dt><dd><tt>Brings this tab to the foreground asynchronously.<br>
<br>
Not all browsers or browser versions support this method.<br>
Be sure to check browser.supports_tab_control.<br>
<br>
Please note: this is asynchronous. There is a delay between this call<br>
and the page's documentVisibilityState becoming 'visible', and yet more<br>
delay until the actual tab is visible to the user. None of these delays<br>
are included in this call.</tt></dd></dl>
<dl><dt><a name="Tab-ClearCache"><strong>ClearCache</strong></a>(self)</dt><dd><tt>Clears the browser's HTTP disk cache and the tab's HTTP memory cache.</tt></dd></dl>

If |script_to_evaluate_on_commit| is given, the script source string will be<br>
evaluated when the navigation is committed. This is after the context of<br>
the page exists, but before any script on the page itself has executed.</tt></dd></dl>

action_function must be a Python function that results in a navigation.<br>

the timeout has been exceeded.</tt></dd></dl>
