+ <td class="content">
+ <p>SWT has added support to set a <code>Control</code>'s background as transparent. The <code>Color</code> class now supports specifying a alpha value (integer: 0 to 255) for transparency.
+ Calling <code>Control#setBackground(Color color)</code> with a transparent color (color with alpha value '0'), sets the control's background as transparent.</p>
+ <p><b>List of New Classes and APIs:</b></p>
+ <ul>
+ <li>Class: <code>org.eclipse.swt.graphics.RGBA</code></li>
+ <li>Constant: <code>SWT.COLOR_TRANSPARENT</code> - This is a default transparent color</li>
+ <li>Methods added in <code>org.eclipse.swt.graphics.Color</code></li>
+ <ul>
+ <li><code>public Color (Device device, int red, int green, int blue, int alpha)</code></li>
+ <li><code>public Color (Device device, RGB rgb, int alpha)</code></li>
+ <li><code>public Color (Device device, RGBA rgba)</code></li>
+ <li><code>public RGBA getRGBA </code>()</li>
+ <li><code>public int getAlpha ()</code></li>
+ </ul>
+ </ul>
+ <p><b>Note:</b></p>
+ <ul>
+ <li>Currently, SWT honors only extreme values for alpha i.e, '0'(transparent) or '255'(opaque).</li>
+ <li>Setting transparent background color fails for some controls on all platforms, they show the default background color instead. For e.g. Text, Combo.</li>
+ <li>Setting transparent background color for some controls works on GTK3 only, it fails on other platforms. For e.g. Table, Tree.</li>
+ </ul>
+ For an example on using the new APIs, see <a href="http://git.eclipse.org/c/platform/eclipse.platform.swt.git/tree/examples/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet365.java">Snippet365</a>.

+ (monitors the creation and disposal of SWT graphics resources) and SWT Spy (prints out information like style, layout and parent
+ about the widget under the cursor).
