actionscript 3 - removeEventListener not working - 


function drag(event:mouseevent):void {     if ((event.target.parent == inventorymenu) && (event.target item)) {         var picked:item = item(event.target);         stage.addeventlistener(mouseevent.mouse_up, drop);         inventoryarrowdown.addeventlistener(mouseevent.mouse_over, inventorynav("down"));         inventoryarrowup.addeventlistener(mouseevent.mouse_over, inventorynav("up"));          function drop(event:mouseevent):void {             if ((event.target.parent == inventorymenu) && (event.target item)) {                 var dropped:item = item(event.target);                           if ((event.target item) && (event.target.parent == inventorymenu)) {                     if (picked.itemdata("workswith") == dropped.name) {                         var itemname:item = item(fetchresult(picked, dropped));                         itemname.addchild(itemname.itemdata("filename"));                         inventorymenu.removechild(picked);                         inventorymenu.removechild(dropped);                         inventorymenu.addchild(itemname);                         inventoryupdate();                     } else if (picked.name != dropped.name) {                         trace("no son compatibles");                     }                     stage.removeeventlistener(mouseevent.mouse_up, drop);                     inventoryarrowdown.removeeventlistener(mouseevent.mouse_over, inventorynav("down"));                     inventoryarrowup.removeeventlistener(mouseevent.mouse_over, inventorynav("up"));                 }             }         }     } }

for reason removeeventlistener on inventoryarrowdown , inventoryarrowup isn't working. i'm sure route correct it's direct copy paste addeventlistener , uses no variables.

any clue what's wrong?

hard without seeing code of inventorynav maybe issue should remove event listeners before tests.

also, should write 2 different handlers instead of using 1 , passing argument do.

here modified version of code might help:

private function drag(event:mouseevent):void {     if ((event.target.parent == inventorymenu) && (event.target item)) {         var picked:item = item(event.target);         stage.addeventlistener(mouseevent.mouse_up, drop);         inventoryarrowdown.addeventlistener(mouseevent.mouse_over, inventorynavdown);         inventoryarrowup.addeventlistener(mouseevent.mouse_over, inventorynavup);     } }  private function drop(event:mouseevent):void {     stage.removeeventlistener(mouseevent.mouse_up, drop);     inventoryarrowdown.removeeventlistener(mouseevent.mouse_over, inventorynavdown);     inventoryarrowup.removeeventlistener(mouseevent.mouse_over, inventorynavup);      if ((event.target.parent == inventorymenu) && (event.target item)) {         var dropped:item = item(event.target);                   if ((event.target item) && (event.target.parent == inventorymenu)) {             if (picked.itemdata("workswith") == dropped.name) {                 var itemname:item = item(fetchresult(picked, dropped));                 itemname.addchild(itemname.itemdata("filename"));                 inventorymenu.removechild(picked);                 inventorymenu.removechild(dropped);                 inventorymenu.addchild(itemname);                 inventoryupdate();             } else if (picked.name != dropped.name) {                 trace("no compatible sons");             }         }     } }

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
