|

80 |
* <p>A simple, static class to display a URL in the system browser.<br></p>
|
|
81 |
*
|
|
82 |
* <p>Under <b>Unix</b> systems, it will open one of the browser set through the
|
|
83 |
* <b>setBrowserCommand(String)</b>. The argument of this method
|
|
84 |
* must be a fully qualified command or one of the commands returned
|
|
85 |
* by <b>getSupportedBrowsers()</b>.<br>By default, the browser is Firefox,
|
|
86 |
* which is included in the list of supported browsers.<br></p>
|
|
87 |
*
|
|
88 |
* <p>Under <b>Windows</b>, this will bring up the default browser under windows,
|
|
89 |
* usually either Netscape or Microsoft IE. The default browser is
|
|
90 |
* determined by the OS so no config is necessary.<br>This has been tested under Windows 95/98/NT/XP.</p>
|
|
91 |
* <p>Notice that <b>you must include</b> the url type -- either "http://" or "file://".</p>
|
|
92 |
*
|
|
93 |
* <p>Under <b>Mac</b>, the usability of this class is pending of test. So probably it does not work</p>
|
|
94 |
* Examples:
|
|
95 |
* BrowserControl.displayURL("http://www.javaworld.com")
|
|
96 |
* BrowserControl.displayURL("file://c:\\docs\\index.html")
|
|
97 |
* BrowserContorl.displayURL("file:///user/joe/index.html");
