From: "Rodolfo García Peñas (kix)" <k...@kix.es>
The default case is moved to the bottom of the switch case.
The default case should be removed, because the icon has always
a right value, because the icon creation always uses a real value:
kix@debian:~/src/wmaker/wmaker-crm/src$ grep wAppIconCreateForDock *c
appicon.c:WAppIcon *wAppIconCreateForDock(WScreen *scr, char *command, char
*wm_instance, char *wm_class, int tile)
dock.c: btn = wAppIconCreateForDock(scr, NULL, "Logo", "WMClip",
TILE_CLIP);
dock.c: btn = wAppIconCreateForDock(scr, NULL, "Logo", "WMDock",
TILE_NORMAL);
dock.c: btn = wAppIconCreateForDock(scr, NULL, name, "WMDrawer",
TILE_DRAWER);
dock.c: aicon = wAppIconCreateForDock(scr, command, winstance, wclass,
TILE_NORMAL);
(1)dock.c: aicon =
wAppIconCreateForDock(dock->screen_ptr, NULL,
kix@debian:~/src/wmaker/wmaker-crm/src$
kix@debian:~/src/wmaker/wmaker-crm/src$ grep TILE_ *c | grep -v ICON_TILE_SIZE
***[2]appicon.c: tile = TILE_CLIP;
dock.c: btn = wAppIconCreateForDock(scr, NULL, "Logo", "WMClip",

TILE_DRAWER);
dock.c: aicon = wAppIconCreateForDock(scr, command, winstance, wclass,

(2)dock.c: wm_instance,
wm_class, TILE_NORMAL);
***[3]icon.c: icon->tile_type = TILE_NORMAL;
icon.c: case TILE_NORMAL:

kix@debian:~/src/wmaker/wmaker-crm/src$ grep tile_type *c

***[1]icon.c: icon->tile_type = tile;

There are only three cases without value (asterisk in the line start) set
as preprocessor variable. (1) and (2) is the same call. These are the three
cases:
Case [1]:
-------------8<--------------
WIcon *icon_create_for_dock(WScreen *scr, char *command, char *wm_instance,
char *wm_class, int tile)
{
WIcon *icon;
icon = icon_create_core(scr, 0, 0);
icon->tile_type = tile;
-------------8<--------------
Calls to icon_create_for_dock, is only call in appicon.c:
-------------8<--------------
kix@debian:~/src/wmaker/wmaker-crm/src$ grep icon_create_for_dock *c
appicon.c: aicon->icon = icon_create_for_dock(scr, command, wm_instance,
wm_class, tile);
icon.c:WIcon *icon_create_for_dock(WScreen *scr, char *command, char
*wm_instance, char *wm_class, int tile)
kix@debian:~/src/wmaker/wmaker-crm/src$
-------------8<--------------
The call:
-------------8<--------------
WAppIcon *wAppIconCreateForDock(WScreen *scr, char *command, char *wm_instance,
char *wm_class, int tile)
{
[snip]
if (strcmp(wm_class, "WMDock") == 0 &&
wPreferences.flags.clip_merged_in_dock)
tile = TILE_CLIP;
aicon->icon = icon_create_for_dock(scr, command, wm_instance, wm_class,
tile);
-------------8<--------------
And the calls to wAppIconCreateForDock() are checked before.
The case [2] is just the line:
-------------8<--------------
WAppIcon *wAppIconCreateForDock(WScreen *scr, char *command, char *wm_instance,
char *wm_class, int tile)
{
[snip]
if (strcmp(wm_class, "WMDock") == 0 &&
wPreferences.flags.clip_merged_in_dock)
*** tile = TILE_CLIP;
aicon->icon = icon_create_for_dock(scr, command, wm_instance, wm_class,
tile);
-------------8<--------------
Then, is sure too.
The case [3] is:
-------------8<--------------
WIcon *icon_create_for_wwindow(WWindow *wwin)
{
[snip]
icon->tile_type = TILE_NORMAL;
-------------8<--------------
All windows have TILE_NORMAL.
Then, all cases are secure.
