Jalopy displays all runtime messages in its own tool window. Messages are shown in a tree control, with each branch containing the messages for a specific file, and individual messages displayed as leafs. File messages show the number of leaves and the warning and error count.
The message types are differentiated with icons and by color: Errors are red with an error icon, warnings are shown in blue and display a warning sign, informational messages are black and carry a file icon and debugging messages are black and prepended by a bug icon.
Clicking on a file name will open that file, clicking on a message that contains location information will open the file containing the message and move the caret to the nominated location.
The window provides a context menu with some useful actions.
| Copy | Copies the textual contents of the selected messages into the System clipboard. If a message contains children, the contents of all children are copied as well |
| Clear | Removes all selected messages |
| Clear All | Removes all messages currently being displayed in the window |
| Select All | Selects all messages currently being displayed in the window |
