| <h3>Launch configuration dialog</h3> |
| <p>Launch configurations can most easily be visualized by looking at their |
| corresponding UI. Users interact with a launch configuration dialog to |
| create instances of the different types of launch configurations that have been |
| contributed by plug-ins. Each type of launch configuration defines a group |
| of tabs that collect and display information about the configuration. The |
| tab group for running a local Java application is shown below.</p> |
| <p><img src="images/lcd.png" alt="Launch configuration dialog with contributed tab groups" border="0"></p> |
| <p>The tabs are contributed using the <a href="../reference/extension-points/org_eclipse_debug_ui_launchConfigurationTabGroups.html"><b>org.eclipse.debug.ui.launchConfigurationTabGroups</b></a> |
| extension point. In this extension, the id of a configuration type (defined using |
| <a href="../reference/extension-points/org_eclipse_debug_core_launchConfigurationTypes.html"><b>org.eclipse.debug.core.launchConfigurationTypes</b></a>) |
| is associated with the class that implements <a href="../reference/api/org/eclipse/debug/ui/ILaunchConfigurationTabGroup.html"><b>ILaunchConfigurationTabGroup</b></a>.</p> |
| <p>It's possible that a some tab groups are only appropriate when launching the configuration in a particular mode. If this is the case, then |
| one or more <b>mode</b> elements can be specified along with the class. For each mode, the tab group can be given a unique description. |
| If no mode is specified, then the tab group will be shown on all modes that |
| do not have a mode-specific tab group contribution. The Java application tab group is defined for run and debug modes:</p> |

| </launchMode> |
| <launchMode |
| mode="run" |
| description="%localJavaApplicationTabGroupDescription.run"> |
| </launchMode> |
| </launchConfigurationTabGroup> |
| ... |
| </pre> |
| <p>Note that a perspective may also be specified with a mode. This will cause the platform to switch to the specified perspective when |
| the program is launched in that mode.</p> |
| <p>Your tab group class is responsible for creating the necessary tabs and |
| displaying and saving the relevant data from the launch configuration |
| attributes. A tab that is common to all configurations, <a href="../reference/api/org/eclipse/debug/ui/CommonTab.html"><b>CommonTab</b></a>, |
| is already implemented and can be created by any configuration. This tab |
| manages the saving of the launch configuration as well as collecting common |
| preferences.</p> |
