hello, is there a way to open a web page in the browser from jframe that contains a button or label
so when the user clicks the button or label the web page will open
hint: the button or label will be generated at run time
Look at the Desktop API . You do something like:
try {
Desktop.getDesktop().browse(new URI("http://www.google.com"));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (URISyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
This method fails gracefully, ie if the page doesn't open it alerts the user and helps them open it manually:
/**
* If possible this method opens the default browser to the specified web page.
* If not it notifies the user of webpage's url so that they may access it
* manually.
*
* @param url
* - the URL of the webpage which you wish to be opened.
*/
public static void openWebpage(String url)
{
try
{
URI uri = new URL(url).toURI();
Desktop desktop = Desktop.isDesktopSupported() ? Desktop.getDesktop() : null;
if (desktop != null && desktop.isSupported(Desktop.Action.BROWSE))
desktop.browse(uri);
}
catch (Exception e)
{
/*
* I know this is bad practice but we don't want to do anything clever for a specific error
*/
e.printStackTrace();
// Copy URL to the clipboard so the user can paste it into their browser
StringSelection stringSelection = new StringSelection(url);
Clipboard clpbrd = Toolkit.getDefaultToolkit().getSystemClipboard();
clpbrd.setContents(stringSelection, null);
// Notify the user of the failure
WindowTools.informationWindow("This program just tried to open a webpage." + "\n"
+ "The URL has been copied to your clipboard, simply paste into your browser to access.",
"Webpage: " + url);
}
}
