Opening specific help topic in eclipse help window programatically?

How I can open specific help topic in eclipse help window programatically running on Linux(Ubuntu 14.04)?

Ex: I want to open "Tasks view" help as shown in below pic pro-grammatically.

enter image description here I tried with:

PlatformUI.getWorkbench().getHelpSystem() .displayHelpResource("/org.eclipse.platform.doc.user/concepts/ctskview.htm");

But the help topic is opening in external browser(firefox) NOT in eclipse help widow.

How I can open this topic in eclipse help widow(Window which opens when clicked Help > Help contents menu in eclipse workbench).

Solution

  • According to your print screen you are using Linux. The internal Window only works for Windows.

    Have a look at the code in DefaultHelpUI (On non Windows platforms, use external when modal window is displayed):

    private boolean useExternalBrowser(String url) {
    // On non Windows platforms, use external when modal window is displayed
    if (!Constants.OS_WIN32.equalsIgnoreCase(Platform.getOS())) {
        Display display = Display.getCurrent();
        if (display != null) {
            if (insideModalParent(display))
                return true;
        }
    }

    // Use external when no help frames are to be displayed, otherwise no
    // navigation buttons.
    if (url != null) {
        if (url.indexOf("?noframes=true") > 0 //$NON-NLS-1$
                || url.indexOf("&noframes=true") > 0) { //$NON-NLS-1$
            return true;
        }
    }
    return false;
}
