| Using content/code assist |
| </h1> |
| <p> |
| You can use content assist (also called code assist) when writing Java code or Javadoc comments. |
| </p> |
| <ol> |
| <li> |
| Place your cursor in a valid position on a line of code in an editor and either |
| <ul> |
| <li> |
| Press <strong>Ctrl</strong>+<strong>Space</strong> |
| </li> |
| <li> |
| Select <strong>Edit</strong> > <strong>Content Assist</strong> from the menu bar |
| </li> |
| </ul> |
| If the Java editor finds valid candidates for this position, a list of possible completions is shown in a floating window. You can type further to narrow the list. You can |
| also hover over the selected list items to view its Javadoc information, if it is available. |
| </li> |
| <li> |
| Use the arrow keys or the mouse pointer to navigate through the possible completions. |
| </li> |
| <li> |
| Select an item in the list to complete the fragment by doing one of the following: |
| <ul> |
| <li> |
| Selecting it and pressing <strong>Enter</strong> |
| </li> |
| <li> |
| Double-clicking it |
| </li> |
| <li> |
| <em>Note: When a list item is selected, you can view any available Javadoc information for this item in hover help. Note that you must click an item to select it in |
| the list before you can view Javadoc hover help for it.</em> |
| </li> |
| </ul> |
| </li> |
| </ol> |
| <p> |
| <em>Note:</em> Completion proposals can be organized into different |
| categories. By default, content assist shows all of them but |
| pressing <strong>Ctrl+Space</strong> repeatedly |
| will cycle through the different categories. Open the |
| <a class="command-link" href='javascript:executeCommand("org.eclipse.ui.window.preferences(preferencePageId=org.eclipse.jdt.ui.preferences.CodeAssistPreferenceAdvanced)")'> |
| <img src="PLUGINS_ROOT/org.eclipse.help/command_link.png"> |
| <strong>Content Assist</strong></a> preference page to configure content assist. |
