Re: setting labels two time in a function

This lets GTK take care of any pending events (like changing the text) before you launch into your long processing function. --rdp On Wed, 15 May 2002, Henning Sprang wrote: > hy, > iwant to set a message in a label while my program does an action that can > sometimes take some time so the user knows the program is working for a while. > > as i did experience problem with this i made a test. > i set the label and let the program sleep for a long time so i can see the > message in any case. parallel, to be sure my info variable is really filled > with content i put it out to the commend line. > > the code looks like this: > > $infolabel->set_text($infotext[1]); > echo "infotext 1 ist:" . $infotext[1]; > sleep(10); > > later, after my actions are done, i change the label again with > > $infolabel->set_text($infotext[2]); > > this one works fine. > > > plus, on the comand line the output is shown, but i never get to see > the first text-cahge in my label, only the second one. > > any reasons for this? > > could it be that calls to gtk object methods get only executed after a > callback function is finished? > > any idea how this can be solved? > > henning > > > > > -- Rich Payne http://talisman.mv.com
