Error message with selectable text
When Kepler displays an error message in the pop-up dialog, the text is not selectable so I can copy-paste it into an email. This makes it tedious to report errors or problems, because I have to retype the whole message.

This would likely be an issue with the Ptolemy Query widget in ptolemy.gui.
I tend not to see this because most error dialogs should be thrown with
an Exception and the dialog should have a "Show Stack Trace" button.
The error message is selectable in the Stack Trace Window.
However, if someone is invoking GraphicalMessageHandler directly, then
the text is probably not selectable.

I'm lowering the priority of this and changing it to an enhancement because
the code works as expected.
I agree that it would be nice if the dialog text was selectable, retyping
an error message is a waste of human effort.
ptolemy.gui.UndeferredGraphicalMessageHandler which uses JOptionPane.
It appears to be a limitation of JOptionPane that the text is not selectable.
for JOptionPane examples,
However, all is not lost. JOptionPane has a message argument and if that
argument is a String, then a JLabel is created.
A descriptive message to be placed in the dialog box. In the most common usage, message is just a String or String constant. However, the type of this parameter is actually Object. Its interpretation depends on its type:
An array of objects is interpreted as a series of messages (one per object) arranged in a vertical stack. The interpretation is recursive -- each object in the array is interpreted according to its type.
The Component is displayed in the dialog.
The Icon is wrapped in a JLabel and displayed in the dialog.
The object is converted to a String by calling its toString method. The result is wrapped in a JLabel and displayed.
So instead of passing a String, I created a method that creates a JTextArea
that looks like a JLabel, but is selectable. I found code at
that got me most of the way there.
So, I modified ptolemy.gui.UndeferredGraphicalMessageHandler so that we
use a JTextField, which looks like a JLabel, but is selectable.
As a fallback, we will return a String if there is a problem.

Now I'm seeing a frame that is too small to accommodate the text and the

The text is wrapping, however!
I'm using MessageHandler.error(String, throwable)
I can't reproduce this.
This can probably be closed. I'm assigning it to Ben pending his approval.
