RE: (Easy?) Newbie enquiry re: pointers

[Madhusudan E <madhusudan huawei com>]

||I am currently attempting to write my first GTK program, which is
|| a graphical mp3 jukebox frontend to the mpg123 linux command.
||I wish to have each button on a grid correspond to a different mp3 track.
||To do this I pass a pointer to a string (the name of the mp3 file) to the
||respective button callback functions.  This all works 
|| well -  the problem is that I have also built a 'reload button'
||which refreshes all the strings so that the same button then plays a
|| different track to before the reload. 
||
||The problem is that 
|| even though the strings the pointers point to do seem to change 
|| (I write them out on leaving gtk_main) the buttons still seem to point to

||the orignal strings, even though they have been overwirtten.
||Thus the button seems locked on to the original mp3 filename
|| even if I overwrite this string.

While rebuilding the UI, you can use gtk_button_set_label() to change the
label name. It will reset the earlier labels used. Hope this helps.

||
||
||I guess this problem is perhaps easily overcome? (I can supply whatever
||details you may require including the code itself).

||Many thanks,
||              Dan.
||p.s. I am new to GUI programming so please keep the advice at 'idiot
level'!
