cvs commit: logging-log4j/src/java/org/apache/log4j/chainsaw/dnd FileDnDTarget.java
psmith 2004/09/01 17:30:19
Modified: src/java/org/apache/log4j/chainsaw/version
VersionManager.java
src/java/org/apache/log4j/chainsaw ChainsawTabbedPane.java
LogUI.java FileLoadAction.java
ChainsawToolBarAndMenus.java
src/java/org/apache/log4j/chainsaw/help release-notes.html
Added: src/java/org/apache/log4j/chainsaw/dnd FileDnDTarget.java
Log:
* Added Drag & Drop (rudimentary) support to Chainsaw. You can drag any File to Chainsaw's
Tabbed Pane area and it will try to load it. If there are no events in the file, not a lot happens...
* Fixed a condition where loading an XML configuration file did not properly use the
correct classloader
* Changed the way the Tabbed Pane functionality works, new tabs are added at the end and
the new tab is not made active.
