c# - UI refresh looping a Dispatcher.BeginInvoke -


i'm trying system.windows.shapes.rectangle rotation in y axis simulating card rotation, showing route.

the problem ui refreshes @ end.

simplified version of code

call of method

for (i=0; i<=180; i++) {     int j = i;     dispatcher.begininvoke(new a_dispatcher(() => {             print_animation_of_card(card, i);         }),          null); }

method

private void print_animation_of_card(system.windows.shapes.rectangle card) {     ...     system.windows.media.planeprojection p =          card.projection system.windows.media.planeprojection;     p.rotationy = i;     card.projection = p; }

i have tried put method, same result...

how can show rotation movement of system.windows.shapes.rectangle?

i believe problem using begininvoke() instead of invoke. not wait 1 angle of rotation complete before next 1 called, calls stacked on top of eachother.

try dispatcher.invoke() or put whole loop inside 1 dispatcher.begininvoke() , see if results more satisfaction.

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...
