Keyboard input not possible within firefox plugin on linux

seraf8 · 02-03-2012, 10:55 AM

Here is my environnement :

openSUSE 11.3
Firefox 3.6.4
java Plugin 1.0.6 u21 ( libnpjp2.so )

Java applet is loading without trouble. Mouse event are well compute by applet, but it is not possible to edit text (for example within an EditText).

It seems there is a problem with the keyboard focus.
If our application opens a separate modal dialog it is possible to edit within such a dialog.

I try to run xwininfo -all in order to understand where is keyboard focus and it seems keyboard focus is keep by another windows created by firefox.

Code:

 xwininfo -all

xwininfo: Please select the window about which you
          would like information by clicking the
          mouse in that window.

xwininfo: Window id: 0x80007c "test"

0x80007d get keyboard focus whereas i expected 0x1400040 to have keyboard focus.
(I use xev -id , to find out which windows hold keyboard focus)

In addition to that, i try to reproduce this problem with export display on a windows using Xming. In this configuration, there is any trouble with keyboard ...
