I'm not sure I understand. You want to button to get it's data from a dir list? Do you mean you want to open a file chooser and select a file which becomes the label? you might want to check out the file chooser button if that's the case.

thanks for the reply,

actually what i am trying to do is something like this :

read the dir -> get file name one at a time -> put the filename to click able button label -> point the button to specific executable command -> get another filename for second button ...... and finish until no more filename to get.

all of it is done in background not by opening filechooser because I believe the /etc/init.d directory (which the program is supposed to read) contains lots of files. thus opening file chooser button everytime for each files is not a good option.

how am i able to get this done in gtk??
