Hey guys.

I have a problem which is really bugging me! its one of those small annoying things i cant seem to get working!!! grrrrrr!!!

anyway, here it goes....

i have a textview and associated text buffer.
bacially i want to save what is in the textview to a file, which i have working.
now i am adding some error handeling which is....

if there is nothing in the textview (i.e its empty) then generate a message
to the users telling them there is nothing to save.

okay...here is a snipet of my code....

Code: (Plaintext)
1 2 3 4 5 6	if (widget->buffer2 != NULL) infile = fopen("/Desktop/file.txt", "a+"); else gtk_text_buffer_set_text (widget->buffer3, "No text to save", -1);

please somebody put me out of my misery!!!!

thanks a mill :)

This may help. Its a snippet from a project I'm working on.
I use the sprintf function to write something to a string called errmessage.
Then insert the string into the GtkTextBuffer.
Then set the buffer into the text view.
It works for me.

Code: (Plaintext)
1 2 3 4 5 6 7 8	gchar errmessage[100]; GtkTextBuffer *buffer = gtk_text_view_get_buffer (GTK_TEXT_VIEW (user_data)); sprintf(errmessage,"\nThe file %s was not written.\n",filename); gtk_text_buffer_insert_at_cursor (buffer, errmessage, -1); gtk_text_view_set_buffer (GTK_TEXT_VIEW (user_data),buffer);

Hey guys.

Its okay, i figured something out.
I just used the get_char_count() function to count how many chars are
in the textview and then said that if count is greater that zero (i.e if there is text in the textview) then save to the file otherwise generate the error.

i cant believe i didnt think of something so simple sooner.

Im pretty new to GTK, Im self learning for a project, so any feedback on why the other way didnt work would be much appreciated :)

Thanks :)
