Re: Memory problem

["Bruce A. Smith" <bruces mail petech ac za>]

Hi Antony

Why bother allocating a new style each time? You can either allocate one new
style when you
initialize the app, or just access the default one. The memory leak is
probably because each time
a new style is created, the old one is not being released. The default one
will be used by other
widgets in the tree and won't be released, while GTK may not track new
styles allocated by the
user for automatic trashing.

Hope this helps
