unsigned long Laxkit::getUniqueNumber ( )

Return a unique unsigned long.

Keeps a static unsigned long, and increments it by 1 on each call. Starts at 0.

void Laxkit::InitLaxImlib ( int megabytes )

Initialize Imlib2 using settings in anXApp::app.

This should be called after anXApp::init() has been called, and of course before using Imlib2 functions.

This will set up the default graphics backend to Imlib. This means all the functions like load_image, image_out, etc, will be based on Imlib calls.

It sets display, visual, and colormap the the defaults of anXApp::app. Also calls imlib_set_cache_size(megabytes * 1024 * 1024), which sets the image cache size to 10megs. You may call this function whenever you want to expand the cache, for instance.

Also sets the default image functions (load_image(), for instance) to imlib based functions that expect LaxImlibImage objects.

int Laxkit::IsWindowChild	(	anXWindow *	top,
		anXWindow *	check
	)

Check if a window (check) is the same as or is descended from another (top).

Returns 1 if top==check, or if check is a child, returns n+1 where n is the number of generations below top. Thus if check is a direct child of top, then return 2. 3 if it is a grandkid, etc.

Otherwise returns 0.

int LaxFiles::one_of_them	(	const char *	str,
