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.
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'!
