Brief introduction

The WebBrowser module provides a high-level interface for displaying Web-based documents. In most cases, simply call the open () function.

Under Unix X11, it is preferred to call the graphics browser. If the graphics browser is unavailable or does not display a terminal, a text-mode browser is used. If you use a text-mode browser, the calling process will block until the user exits the browser.

If the browser environment variable is set, it overrides the default browser list for the platform. Browser is a list of browsers that are os.pathsep segmented. If a partial value of the list contains the string "%s", the argument to the browser command line is resolved.

When using a remote browser for a non-UNIX platform or UNIX, the control process does not wait for the user to complete the browse, but allows the remote browser to display its own window. If there is no remote browser, the control process will launch a new browser and wait.

The WebBrowser supports the command line interface. It accepts the URL as a parameter. Optional parameter: "-n" opens the URL in a new browser window; "-T" opens a new tab.

    • Exception: Exception webbrowser. Error: This exception is thrown when the browser controls an error.

    • (URL, new=0, autoraise=true)

Use the default browser to access the URL. If new equals 0, the URL is opened as far as possible in an existing browser window. If new is equal to 1, it opens a newer browser window. New equals 2, as far as possible, open the label (tab) in the browser. If Autoraise is true, the browser window appears first (note that in most window managers).

Note on some platforms, the system's associated program may be started when the file name is opened. Other systems default to the most resource-efficient way to open the browser.

    • Webbrowser.open_new (URL)

Use the default browser to open the URL, try to have only one window

    • Webbrowser.open_new_tab (URL)

Use the default browser to open the URL in the new tab.

    • Webbrowser.get ([name])

Returns the development of a browser controller object. If name is empty, the controller of the default browser is returned.

    • Webbrowser.register (name, constructor, Instance=none)

Registered Browser type: name. The Get () function can return a controller of that browser type after registration. If instance is not provided or none, the constructor can call without arguments and create an instance. If a instance is provided, the constructor is not called.

This entry a-useful if you plan to either set the BROWSER variable or call get () with a nonempty argument MATC Hing the name of a handler you declare.

Valid only if you set the browser variable or call get () with a non-null argument. You declare the name of a handler to match.
