| <p>The <a href="http://wiki.eclipse.org/Juno">Juno</a> annual release is almost upon us! Here are some of the |
| more noteworthy things available in milestone build M7 |
| (May 4, 2012) which is now available for <a href="http://download.eclipse.org/eclipse/downloads/" target="_top">download</a>. |
| Unless otherwise indicated, all entries listed here are available in both the 3.8 and 4.2 development streams.</p> |

| <td class="title">Lightweight refresh enabled by default (4.2 only)</td> |
| <td class="content"> |
| In Eclipse 3.7 a new lightweight refresh mechanism was introduced. Files discovered to be out-of-sync |
| by the workspace, for example while accessing the file content by an editor, |
| are automatically asynchronously refreshed. In Eclipse 3.7 and 3.8 you have to enable this yourself |
| via <b>Preferences > General > Workspace</b> and select <b>Refresh on access</b>. |
| In Eclipse SDK 4.2 the mechanism is enabled by default. |

| <td class="title">Trim dragging (4.2 only)</td> |
| <td class="content"> |
| We have finally re-introduced the ability to drag some of the window trim elements around. |
| For example, you can drag minimized stacks to different edges of the main window. |

| |
| <tr id="trim-styling"> |
| <td class="title">Trim styling (4.2 only)</td> |
| <td class="content"> |
| In the new window trim implementation, the drag handle and the frame surrounding the trim are |
| defined through CSS. Here's an example of what this looks like: |
| <pre> |
| .MToolControl.TrimStack { |
| frame-image: url(./winXPTSFrame.PNG); |
| handle-image: url(./winXPHandle.PNG); |
| frame-cuts: 5px 1px 5px 16px; |
| } |
| </pre> |
| <p><tt>frame-image</tt> and <tt>handle-image</tt> define the images to be used to draw the frame. |
| The <tt>frame-cuts</tt> attribute is a set of 4 integer values that are used to divide the <tt>frame-image</tt> |
| into specific areas by defining two widths and two heights (the third is just the image size minus the |
| sum of the other two. This allows us to determine what part of the image to use for the top/right corner.</p> |
| <p>Here is a more interesting example that illustrates the power this gives to applications to customize their appearance:</p> |

| <p> When you enable the option <b>Preferences > Java > Compiler > Errors/Warnings > Switch is missing default case</b>, JDT will flag switch statements with a missing default |

| <p> When you enable the sub-option <b>Preferences > Java > Compiler > Errors/Warnings > Signal even if default case exists</b> for the <b>Incomplete switch cases on enum</b> option, |
| JDT will flag switch statements over an enum type which may have an enum value covered only through a default statement, but not directly through a case |
| statement. When new enum constants are added, this option will help in detecting the switch statements that do not cover the new value.</p> |

| <p>You can hover over a closing curly brace and see the source near the matching opening brace in a hover. |
