Releases
Instructions: Click on the link to download the JAR file and place it in the dropins directory of Eclipse
Requirements: Eclipse 3.4 RC4 or later
- 2008-06-30. Split editor with basic functionality (undo/redo, cut/copy/paste, cursor line highlight, action contributions to menu/toolbar/statusbar) working correctly.
- 2008-06-23. 1st release of multi editor and split editor implementations. Instructions: Download the plugin jar and place in the dropins directory (compatible with Eclipse 3.4 RC4 or later).
Implementations
Multi Editor-based
Usage: Open a file in Eclipse, then select Window -> New Split Editor from the main menu to open a split editor of the file.
This implementation is based on Paul Webster's patch, which uses the existing multi-editor architecture in Eclipse.
- Advantages
- does not require custom work for different editor types (java/xml/etc)
- works automatically with new custom editor types
- Disadvantages
- Split editor opens in a new tab as opposed to appearing within the existing tab
- Activating with the mouse requires going to the main menu (Window->New Split Editor). There is also a keyboard shortcut - Ctrl+6.
- Bound by the limitations of the multi-editor infrastructure
Custom Split Editor Implementation
Usage: Right-click on a file, select Open with -> Other... and select \[Split Text Editor\] from the list of editors.
This implementation is based on a custom editor implementation that dynamically creates a new StyledText control when a sash is dragged within the editor to split it.
- Advantages
- fully replaces existing editors and allows splitting the active editor in-place (as opposed to opening a split editor in a new tab)
- easier activation via the mouse because there is no need to go to the window main menu or editor tab context menu.
- Disadvantages
- requires customization of every editor class that wants to support split editing (java/xml... etc)
