Splash Screen

Here is the Splash Screen that I created for OpenBiomind-GUI. I used GIMP to create this image. Clearly, I am not an artist and this was my first attempt at making an image :)

Creating/Opening Link using Eclipse SWT

I recently had a need to use hyperlinks (though I did not use it eventually). Here is a snippet to create hyperlinks in using Eclipse SWT.
<br />/*<br /> * Specific to Eclipse SWT<br /> * Related packages<br /> * - org.eclipse.swt.widgets.Link<br /> * - org.eclipse.swt.events.SelectionAdapter<br /> * - org.eclipse.swt.events.SelectionEvent<br /> * - org.eclipse.swt.SWT<br /> * - org.eclipse.swt.program.Program<br /> */<br />final Link link = new Link(parent, SWT.NONE);<br />link.setText("Visit <a href=\"http://code.google.com/p/openbiomind-gui/\">OpenBiomind-GUI homepage</a>");<br /><br />/*<br /> * You can use Selection Listener to identify the text that was clicked.<br /> * For e.g. here when user clicks on the hyperlink named OpenBiomind-GUI<br /> * then its href text, that is, http://code.google.com/p/openbiomind-gui/<br /> * is set as event.text.<br /> */<br />link.addSelectionListener(new SelectionAdapter() {<br /><br /> @Override<br /> public void widgetSelected(final SelectionEvent event) {<br /> // this will open the hyperlink in the default web browser<br /> Program.launch(event.text);<br /> }<br /><br />});<br />

Creating NUM_ONLY Text Field using Eclipse SWT

While working on a wizard, I needed to use text fields that accept only numbers. Following is a snippet of what I used. This text field will only accept digits as input. All other inputs (barring a few) are discarded.
<br />/* <br /> * Specific to Eclipse SWT.<br /> * Related packages<br /> * - org.eclipse.swt.widgets.Text<br /> * - org.eclipse.swt.events.VerifyListener<br /> * - org.eclipse.swt.events.VerifyEvent<br /> * - org.eclipse.swt.SWT<br /> */<br /><br />final Text text = new Text(parent, SWT.SINGLE | SWT.BORDER); // use desired style<br />// Use text.setTextLimit(...) to set a limit on number of digits<br /><br />/*<br /> * You need to use Verify Listener.<br /> * Key Listener will not block Paste actions, and users may still be able to<br /> * paste non numerals in the text field<br /> */<br />text.addVerifyListener(new VerifyListener() {<br /><br /> @Override<br /> public void verifyText(final VerifyEvent event) {<br /> switch (event.keyCode) {<br /> case SWT.BS: // Backspace<br /> case SWT.DEL: // Delete<br /> case SWT.HOME: // Home<br /> case SWT.END: // End<br /> case SWT.ARROW_LEFT: // Left arrow<br /> case SWT.ARROW_RIGHT: // Right arrow<br /> return;<br /> }<br /><br /> if (!Character.isDigit(event.character)) {<br /> event.doit = false; // disallow the action<br /> }<br /> }<br /><br />});<br />
