Hi! I'm trying to compile into linux an application that I wrote in
Lazarus under windows and I've noticed TProcess component doesn't work
fine if the properties windowheight, windowwidth... and the
complementary suoUseShow, suoUseSize have different values than the
default ones false or zero (I've obtained the same behaviour with very
simple examples). Under windows it works fine (I can force the
dimension
the application that I launch with the tprocess component), but in
linux
it's simply not launched (I'm probing with evince pdf viewer under
ubuntu gutsy gibbon tribe 3). If I let the default values for those
properties tprocess launch evince successfully. :?:

If you can provide detailed information about what happens, try the
bugtracker.

I don't know how to use the bugtracker but is very simple to reproduce
the issue. Only drag a tprocess object into a form, put in the
commandline propertie "evince" and then change the value of windowwith
to a value different of zero. When you tun the project evince doesn't
appear. Then put that propertie to zero (maybe you have to change
suouseSize to false because the change of windowwidth put that
propertie to true) and evince appears.

I did it, but when I tried to set TProcess' Active property to True, I
obtained the error message "Failed to execute 'evince' : 2".

I tried "notepad" (win32) instead of "evince" and, when I set Active
property to True, Notepad executes even on design time.

I said that tprocess doesn't work in linux, but  your are trying it in
windows. Evince, as far as I know, only exists in linux, that is the
reason that you get that error. Under windows tprocess works fine.

OK Use the bugtracker, so. It's easy.
