Hey,

Working on a new desklet but it's giving me this error:

Code:


Traceback (most recent call last):
  File "deskicon.py", line 173, in ?
    Events(dirname(__file__)).pause()
  File "/usr/lib/python2.4/site-packages/adesklets/events_handler.py", line 228, in pause
    posix_signal.pause()
  File "/usr/lib/python2.4/site-packages/adesklets/events_handler.py", line 188, in _fire_event
    self._alarm()
  File "/usr/lib/python2.4/site-packages/adesklets/events_handler.py", line 296, in _alarm
    timeout=self.alarm()
  File "deskicon.py", line 142, in alarm
    self._display()
  File "deskicon.py", line 156, in _display
    adesklets.window_resize(self.x, self.y)
  File "/usr/lib/python2.4/site-packages/adesklets/commands.py", line 1437, in window_resize
    return comm.out()
  File "/usr/lib/python2.4/site-packages/adesklets/commands_handler.py", line 103, in out
    raise ADESKLETSError(4,message)
adesklets.error_handler.ADESKLETSError: adesklets command error - did not resize window

The desklet is sort of modular, one module works fine but another doesn't, hard to explain. Each module (class) must have a dimensions() method that returns X and Y values to pass to adesklets.window_resize(). If I print these values I can't see anything wrong with them, the desklet appears but after one second it dies with that error, I'm assuming the second run of Events._display(). I'm guessing the cause of the error is somewhere in my mount_icon.update() but I can't see where it is. I stole a little bit of code from mounter, I haven't put much effort into the else at line 45 of mount_icon.py because my testing partition is mounted and I want to get it to a working stage before I fine tune it too much.

A second pair of eyes would be appreciated, I've been staring at this for ages and I can't find the problem, exec_icon works great so I don't think the problem stems from any code in deskicon.py. I've put a tarball of the code here, if somebody could take a look I'd appreciate it :)

Okay, I went out before and now I've had time to think, I changed with window_resize() code to this:

Code:


if (x, y) != (self.x, self.y):
                                self.x = x
                                self.y = y
                                adesklets.window_resize(self.x, self.y)

...and the problem is solved. Now it only tried to resize the window when it is needed which is probably a good thing but does adesklets not like resizing a windows to the same size?

Well, you are right that I could have made it a no-operation as easily (here you go) -- the fatal error is a bit uncivil, but justified by the fact that invoking this unrequired adesklets command is probably more wasteful than performing the check in the first place. Yours,
