Greetings,
First post. Wish me luck. :)
I compiled the examples in the gtk library and have been exploring them in
order to learn how gtk+ works.
Subject: gtk+/gtk+-2.14.6/examples/tree/tree.c
(1) suggestion for improvement
Based on the declaration of
static gchar *itemnames[] = {"Foo", "Bar", "Baz", "Quux", "Maurice"};
is there any reason that the following can't be used to substitute for the
constant 5 in the for loops?
const gint name_count = sizeof( itemnames ) / sizeof( itemnames[ 0 ] );
then , instead of
for (i = 0; i < 5; i++){...}
you would have
for (i = 0; i < name_count; i++){...} ?
That way if someone wants to add or remove items from the name list, one would
not need to change the integer values in each for loop that depends on the char
arrays. (lower maintenance)
(2) single / double click ?
The " select_child " callback is called only when an item is double-clicked,
when I would expect a single-click would make a selection. Why? (Application
called using Applications -> Accessories -> Terminal ( $ ./tree) because I
wanted to see the g_print( ) output.
Thanks for your help.
Dave
