| * Browser example snippet: listen for DOM mousedown events with javascript |
| * (Eclipse/SWT 3.4 and earlier). For an improved implementation of this |
| * snippet that can be used with Eclipse/SWT 3.5 and newer see |
| * http://git.eclipse.org/c/platform/eclipse.platform.swt.git/tree/examples/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet362.java . |
| * |
| * This snippet works for all supported browser types (ie.- Browsers created with style |
| * SWT.NONE). For a Browser created with style SWT.MOZILLA an alternate approach would |
| * be to use JavaXPCOM to hook the DOM listeners. |
