Yep.
1.In nanowm.h add :
/*mouse position structure */
typedef struct {
GR_WINDOW_ID wid;
GR_COORD x;
GR_COORD y;
} Wm_move;
……
extern Wm_move wm_move;
2. In actions.c add(at the very head):
GR_TIMER_ID wm_timer;
Wm_move wm_move;
At the very end of Wm_container_buttondown(),midify to:
……
window->active = GR_TRUE;
#ifndef OUTLINE_MOVE
wm_timer=GrCreateTimer(window->wid,1,1);
#endif
}
In fuction Wm_container_buttonup(),modify original to
……
if(window->active) {
pos = (struct Wm_pos_size *)window->data;
#ifdef OUTLINE_MOVE
gc = GrNewGC();
GrSetGCMode(gc, GR_MODE_XOR|GR_MODE_EXCLUDECHILDREN);
GrRect(GR_ROOT_WINDOW_ID,gc,pos->xorig, pos->yorig, pos->width,
pos->height);
GrMoveWindow(window->wid, pos->xorig, pos->yorig);
#endif
free(pos);
window->active = GR_FALSE;
window->data = 0;
#ifndef OUTLINE_MOVE
GrMoveWindow(wm_move.wid,wm_move.x,wm_move.y);/*move too the final position*/
GrDestroyTimer(wm_timer);
#endif
}
……
In fuction Wm_container_mousemoved(),modify :
……
#else
GrMoveWindow(window->wid, event->rootx - pos->xoff,
event->rooty - pos->yoff);
#endif
……
TO
……
#else
wm_move.wid=window->wid;
wm_move.x=event->rootx - pos->xoff;
wm_move.y=event->rooty - pos->yoff;
#endif
……
3.In enents.c : in fuction WmHandleEvent() add:
……
case GR_EVENT_TYPE_TIMER:
#ifndef OUTLINE_MOVE
GrMoveWindow(wm_move.wid,wm_move.x,wm_move.y);
#endif
break;
default:
break;
……
4.In clinets.c in fuction Wm_new_client_window（）in
GrSelectEvent() add timer event:
……
GrSelectEvents(pid, GR_EVENT_MASK_CHLD_UPDATE
| GR_EVENT_MASK_BUTTON_UP | GR_EVENT_MASK_BUTTON_DOWN
| GR_EVENT_MASK_MOUSE_POSITION | GR_EVENT_MASK_EXPOSURE
| GR_EVENT_MASK_TIMER);
……
I think that's all, any problem ,please tell me .
