Emacs is able to display native widgets, such as GTK WebKit widgets,
in Emacs buffers when it was built with the necessary support
libraries and is running on a graphical terminal. To test whether
Emacs supports display of embedded widgets, check that the
xwidget-internal feature is available (see Named Features).
To display an embedded widget in a buffer, you must first create an
xwidget object, and then use that object as the display specifier
display text or overlay property (see Display Property).
This creates and returns an xwidget object. If buffer is omitted or
nil, it defaults to the current buffer. If buffer names a buffer that doesn't exist, it will be created. The type identifies the type of the xwidget component, it can be one of the following:
- The WebKit component.
The width and height arguments specify the widget size in pixels, and title, a string, specifies its title.
This function replaces the property list of xwidget with a new property list given by plist.
This function returns a list of xwidget objects associated with the buffer, which can be specified as a buffer object or a name of an existing buffer, a string. The value is
nilif buffer contains no xwidgets.
This function browses the specified uri in the given xwidget. The uri is a string that specifies the name of a file or a URL.
This function executes the specified script like
xwidget-webkit-execute-scriptdoes, but it also returns the script's return value as a string. If script doesn't return a value, this function returns default, or
nilif default was omitted.
This function returns the title of xwidget as a string.
This function resizes the specified xwidget to the size widthxheight pixels.
This function returns the desired size of xwidget as a list of the form
). The dimensions are in pixels.
This function returns the attributes of xwidget as a vector of the form
[type title width height
]. The attributes are usually determined by
make-xwidgetwhen the xwidget is created.
This function allows you to arrange that Emacs will ask the user for confirmation before exiting or before killing a buffer that has xwidget associated with it. If flag is non-
nil, Emacs will query the user, otherwise it will not.
