The fix is safe and should not break plugins or anything else. git-svn-id: https://zerowing.idsoftware.com/svn/radiant/GtkRadiant/trunk@437 8a3a26a2-13c4-0310-b231-cf6edde360e5 --- diff --git a/radiant/filters.cpp b/radiant/filters.cpp index 17a91195..27ca8437 100644 --- a/radiant/filters.cpp +++ b/radiant/filters.cpp @@ -30,14 +30,38 @@ SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. #include "stdafx.h" -// type 1 = texture filter (name) -// type 3 = entity filter (name) -// type 2 = QER_* shader flags -// type 4 = entity classes -// type 5 = surface flags (q2) -// type 6 = content flags (q2) -// type 7 = content flags - no match (q2) -bfilter_t *FilterAdd(bfilter_t *pFilter, int type, int bmask, const char *str, int exclude) +/* + Rambetter on Sun Jan 23, 2011: + + What follows is a discussion of the introduction to some new members and functions + such as baseFilters, baseFilterExcludes, FilterAddImpl(), and so on. + + There was a problem that "base" filters were not taking effect as a result of + user action such as clicking a filter checkbox. The reason why the base filters + were not being updated is because the previous logic of updating the filters had + been commented out. It was commented out because the previous logic deleted ALL + filters (including plugin filters) and re-created only the base filters. So in + effect, all plugin filters would be deleted whenever a filter checkbox was altered. + + So, we need some way of knowing which are the base filters so that we can take + action when a filter checkbox is marked [or unmarked]. Then we can update + the base filters by either deleting and recreating them, or by changing their + active state in an intelligent manner. I am choosing to do the latter. + + My goal here is to preserve the structure bfilter_t completely as it has been + historically. I feel that modifying bfilter_t is dangerous with respect to breaking + plugins. So what I'm doing instead is tracking which are the base filters via + external array, baseFilters. The array baseFilterExcludes keeps track of the "exclude" + parameter for the corresponding filter. +*/ + +#define MAX_BASE_FILTERS 32 +static bfilter_t *baseFilters[MAX_BASE_FILTERS]; +static int baseFilterExcludes[MAX_BASE_FILTERS];
