Thanks for the quick reply. Adding WAIT to the SHELL command is not causing the mouse cursor to change to Mouse.Wait :(

Hi,

Heres how i "fixed" it, hope it is the right way to display a "wait" cursor while a process executes.

-------------------------
FMain.Mouse = Mouse.Wait
WAIT 
Application.Busy = 1

SHELL "sha512sum lenny.iso" TO actualSUM

Application.Busy = 0
FMain.Mouse = Mouse.Default
-------------------------

I read "If you call WAIT from an event handler, you may create infinite recursions, and then stack overflows" from the Docs, i hope it wouldn't be an issue in this case (i.e., if i were to use WAIT for the click event of a Button).

Regards,
Vikram

Setting FMain.Mouse and calling WAIT is useless. Application.Busy should 
already set the busy cursor for every widget in the application. Otherwise 
this is a bug.

That was what I thought too, but Application.Busy alone is not showing a 
busy pointer (anymore?) on latest gambas 2 and Ubuntu 10.04 with gb.qt

Application.Busy alone is not showing a busy pointer on Debian Squeeze, with Gambas 2.21.

I use

INC Application.Busy

and

DEC Application.Busy

in my applications on Debian Lenny (with LXDE)
and Gambas 2.21 and it works just fine.

I see: with gb.gtk, Application.Busy > 0 works only if the event loop is run 
just after (i.e. you call WAIT just after INC Application.Busy).

No idea why, I will look at that...

Strange, this simply works here:

' Gambas class file

PUBLIC SUB Form_Open()

END

PUBLIC SUB Form_Activate()

   DIM Checksum AS String

   ME.Mouse = Mouse.Wait
   Application.Busy = TRUE

   SHELL "ls -lR" TO checksum

   Application.Busy = FALSE
   ME.Mouse = Mouse.DEFAULT

   'PRINT checksum

END

Gambas 2.21.x, ubuntu 10.4, gb.qt

Ron_2nd.

No, but it waits until the shell command is finished. So you have a 
defined period of time for the mouse cursor to change its shape.

Otherwise, your program will just go on, leaving the shell alone, and 
the change of the mouse is too short to notice...
