JTA Applet lost focus with TAB key event when JTA is run as Applet

[focusbug]

Binary package hint: ubufox

Hi,

I am running into some weird focus issue with JTA Applet (actually any applet with only 1 component in it, but let's just use the JTA applet for testing/debugging purposes) if I launch the JTA as an embedded applet. When I type in the JTA telnet window, other keys works fine. But, when I press the Tab key, the browser holding this applet seems to steal the focus and transfer it to the next focusable component on the browser frame. Repeated TAB keypress does not return the focus back to the JTA applet.

In comparison, on other OSes (Windows, Linux, Mac), when I press the Tab key, the tab key event is reflected on my applet, but the focus remains inside the applet window. Ubuntu's behavior seems to differ from the others.

I have changed following settings in the jta.conf file:

Applet.detach = false
Applet.detach.fullscreen = false
Applet.detach.immediately = false
Applet.detach.menuBar = false

If I run the JTA as an application, the TAB works fine. But, I am reporting this bug as a general bug with how Ubuntu handles the Tab key event with applet.

As a different example, I wrote a simple applet containing only a Text Area...in Ubuntu, when I type the Tab key in the text area, the focus is lose. When I run the same applet in Windows and type the same thing, the focus remains in the TextArea and I can continue typing.

I want to reiterate that I am reporting this bug on how Ubuntu handles the tab key event in applet. So, don't worry so much about a workaround with JTA specifically. I know JTA will work fine if I run it as an "application" or if I set the Applet.detach.* parameters to true.

Thanks!
