SWT 浏览器 - 它使用哪种浏览器？

Question

How can I tell which OS browser the SWT browser uses if there are multiple installed?

I am specifically asking about Windows and OSX.

This is related to Clear SWT Browser cache .

Answer 1

Use browser.getBrowserType() method. see: https://help.eclipse.org/2020-12/topic/org.eclipse.platform.doc.isv/reference/api/org/eclipse/swt/browser/Browser.html#getBrowserType()

// ... your code

final var browser = new Browser(shell, SWT.NONE);

browser.setUrl("https://www.google.com/");

/** 
 * Description: Returns the type of native browser being used by this instance. Examples: 
 * "ie", "mozilla", "voyager", "webkit"
 */
System.out.println(browser.getBrowserType());

Or

Solution with JS: Find browser type/version of SWT Browser

// ... your code

final var browser = new Browser(shell, SWT.NONE);

browser.setUrl("https://www.google.com/");

System.out.println(browser.evaluate("var ua = navigator.userAgent, tem, M = ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\\/))\\/?\\s*(\\d+)/i) || []; if (/trident/i.test(M[1])) { tem = /\\brv[ :]+(\\d+)/g.exec(ua) || []; return 'IE ' + (tem[1] || ''); } if (M[1] === 'Chrome') { tem = ua.match(/\\b(OPR|Edge)\\/(\\d+)/); if (tem != null) return tem.slice(1).join(' ').replace('OPR', 'Opera'); } M = M[2] ? [M[1], M[2]] : [navigator.appName, navigator.appVersion, '-?']; if ((tem = ua.match(/version\\/(\\d+)/i)) != null) M.splice(1, 1, tem[1]); return M.join(' ');"));
