ICCCM mandates the use of real timestamps to interact with the selection, to rule out race conditions if the clients are run at different speeds. I have implemented the low hanging fruit, putting the timestamps into text selection. Also, ICCCM mandates a check for whether XSetSelectionOwner() worked. Not sure my version is correct, though. --- st.c | 21 +++++++++++++-------- 1 file changed, 13 insertions(+), 8 deletions(-) diff --git a/st.c b/st.c index f874127..6bfa834 100644 --- a/st.c +++ b/st.c @@ -423,7 +423,7 @@ static void xsettitle(char *); static void xresettitle(void); static void xsetpointermotion(int); static void xseturgency(int); -static void xsetsel(char *); +static void xsetsel(char *, Time); static void xtermclear(int, int, int, int); static void xunloadfont(Font *); static void xunloadfonts(void); @@ -449,7 +449,7 @@ static void selinit(void); static void selnormalize(void); static inline bool selected(int, int); static char *getsel(void); -static void selcopy(void); +static void selcopy(Time); static void selscroll(int, int); static void selsnap(int, int *, int *, int); static int x2col(int); @@ -984,8 +984,8 @@ getsel(void) { } void -selcopy(void) { - xsetsel(getsel()); +selcopy(Time t) { + xsetsel(getsel(), t); } void @@ -997,7 +997,7 @@ selnotify(XEvent *e) { XSelectionEvent *xsev; ofs = 0; - xsev = (XSelectionEvent *)e; + xsev = &e->xselection; if (xsev->property == None) return; do { @@ -1083,6 +1083,9 @@ selrequest(XEvent *e) { xev.selection = xsre->selection; xev.target = xsre->target; xev.time = xsre->time; + if (xsre->property == None) + xsre->property = xsre->target; + /* reject */ xev.property = None; @@ -1125,11 +1128,13 @@ selrequest(XEvent *e) { } void -xsetsel(char *str) { +xsetsel(char *str, Time t) { free(sel.primary); sel.primary = str; - XSetSelectionOwner(xw.dpy, XA_PRIMARY, xw.win, CurrentTime); + XSetSelectionOwner(xw.dpy, XA_PRIMARY, xw.win, t); + if (XGetSelectionOwner(xw.dpy, XA_PRIMARY) != xw.win) + selclear(0); } void @@ -1146,7 +1151,7 @@ brelease(XEvent *e) { selclear(NULL); } else { getbuttoninfo(e); - selcopy(); + selcopy(e->xbutton.time); } sel.mode = 0; tsetdirt(sel.nb.y, sel.ne.y); -- cgit v1.2.3
