Dear List,
I have studied the example program for creating a progress bar and tried some
variations. For my application, the user must set a few parameters and open a
few data files. I would like to have the progress bar start up after that. For
whatever reason, although I can see the outline of the progress bar, I cannot
get it start or write text into it with a callback function that is executed
when the user clicks on "start".
The function is something like this:
static void start_progress_and_calculations( GtkWidget *w,
gpointer data ){
pdata->timer = g_timeout_add (100, calculate_bspc, pdata);
calculate_lots_of_neat_stuff(pdata);
}
calculate_lots_of_neat_stuff in turn has some code such as
gtk_progress_bar_set_text (GTK_PROGRESS_BAR (pdata->pbar), "Input data");
gtk_progress_bar_set_fraction (GTK_PROGRESS_BAR (pdata->pbar), 0.9);
...
What am I doing wrong? Sorry if these are dumb questions, it's my first GTK
app...
gruss, Peter
