        Returns the result, if any, of executing the specified script.

        Evaluates a script containing javascript commands. When trusted is true script is executed in the context of Chrome with Chrome security privileges. When trusted is false script is executed in the context of the current document with normal privileges.

        If document-defined functions or properties are accessed by the script then this method should not be invoked until the document has finished loading (ProgressListener.completed() gives notification of this).

        Returns the receiver's style information.

        Note that the value which is returned by this method may not match the value which was provided to the constructor when the receiver was created. This can occur when the underlying operating system does not support a particular combination of requested styles. For example, if the platform widget used to implement a particular SWT widget always has scroll bars, the result of calling this method would always have the SWT.H_SCROLL and SWT.V_SCROLL bits set.

        Overrides:
        getStyle in class org.eclipse.swt.widgets.Widget
        Returns:
        the style bits

      • getText

        public String getText()
        Returns a string with HTML that represents the content of the current page.
        Returns:
        HTML representing the current page or an empty String if this is empty.

        Note, the exact return value is platform dependent. For example on Windows, the returned string is the proccessed webpage with javascript executed and missing html tags added. On Linux and OS X, this returns the original HTML before the browser has processed it.

      • setText

        public boolean setText​(String html)
        Renders a string containing HTML. The rendering of the content occurs asynchronously. The rendered page will be given trusted permissions; to render the page with untrusted permissions use setText(String html, boolean trusted) instead.

        The html parameter is Unicode-encoded since it is a java String. As a result, the HTML meta tag charset should not be set. The charset is implied by the String itself.

        Parameters:
        html - the HTML content to be rendered
        Returns:
        true if the operation was successful and false otherwise.
        Throws:
        IllegalArgumentException -

      • setText

        public boolean setText​(String html,
                               boolean trusted)
        Renders a string containing HTML. The rendering of the content occurs asynchronously. The rendered page can be given either trusted or untrusted permissions.

        The html parameter is Unicode-encoded since it is a java String. As a result, the HTML meta tag charset should not be set. The charset is implied by the String itself.

        The trusted parameter affects the permissions that will be granted to the rendered page. Specifying true for trusted gives the page permissions equivalent to a page on the local file system, while specifying false for trusted gives the page permissions equivalent to a page from the internet. Page content should be specified as trusted if the invoker created it or trusts its source, since this would allow (for instance) style sheets on the local file system to be referenced. Page content should be specified as untrusted if its source is not trusted or is not known.

        Parameters:
        html - the HTML content to be rendered
        trusted - false if the rendered page should be granted restricted permissions and true otherwise
        Returns:
        true if the operation was successful and false otherwise.

                              String[] headers)
        Begins loading a URL. The loading of its content occurs asynchronously.

        If the URL causes an HTTP request to be initiated then the provided postData and header arguments, if any, are sent with the request. A value in the headers argument must be a name-value pair with a colon separator in order to be sent (for example: "user-agent: custom").

        Parameters:
        url - the URL to be loaded
        postData - post data to be sent with the request, or null
        headers - header lines to be sent with the request, or null
        Returns:
        true if the operation was successful and false otherwise.

      • dispose

        public void dispose()
        Disposes of the operating system resources associated with the receiver and all its descendants. After this method has been invoked, the receiver and all descendants will answer true when sent the message isDisposed(). Any internal connections between the widgets in the tree will have been removed to facilitate garbage collection. This method does nothing if the widget is already disposed.

        NOTE: This method is not called recursively on the descendants of the receiver. This means that, widget implementers can not detect when a widget is being disposed of by re-implementing this method, but should instead listen for the Dispose event.

        Overrides:
        dispose in class org.eclipse.swt.widgets.Widget
        Throws:
        org.eclipse.swt.SWTException -
        • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver

        Returns a ChromiumBrowser API instance for the current browser.
