java - My cube in lwjgl doesn't render correctly -


i followed tutorial opengl found here provided top answer this question cube refuses render front , faces, other faces render, same problem pyramid. here source code:

public void render(){     gl11.glmatrixmode(gl11.gl_projection);     gl11.glloadidentity();     gl11.glortho(0, display.getdisplaymode().getwidth(), 0, display.getdisplaymode().getheight(), -1, 1);     gl11.glclear(gl11.gl_color_buffer_bit | gl11.gl_stencil_buffer_bit); //clear screen      //center square according screen size     gl11.glpushmatrix();     if(display.wasresized()){         mx = 0; //mx mouse x position         = 0; //my mouse y position     }     if((mx == 0 && ==0)){         gl11.gltranslatef((display.getwidth()/2), (display.getheight()/2), 0.0f);     }else{         gl11.gltranslatef(mx+50, my+50, 0.0f);     }     gl11.glrotatef(angle, 0.0f,1.0f,0.5f); //angle angle of quads rotation     gl11.glbegin(gl11.gl_quads);      gl11.glcolor3f(0.0f,1.0f,0.0f);     gl11.glvertex3f(50.0f, 50f, -50f);     gl11.glvertex3f(-50.0f, 50f, -50f);     gl11.glvertex3f(-50.0f, 50f, 50f);     gl11.glvertex3f(50.0f, 50f, 50f);      gl11.glcolor3f(0.0f,0.5f,0.0f);     gl11.glvertex3f(50.0f, -50f, 50f);     gl11.glvertex3f(-50.0f, -50f, 50f);     gl11.glvertex3f(-50.0f, -50f, -50f);     gl11.glvertex3f(50.0f, -50f, -50f);      gl11.glcolor3f(1.0f,0.0f,0.0f);     gl11.glvertex3f(50.0f, 50f, 50f);     gl11.glvertex3f(-50.0f, 50f, 50f);     gl11.glvertex3f(-50.0f, -50f, 50f);     gl11.glvertex3f(50.0f, -50f, 50f);      gl11.glcolor3f(1.0f,1.0f,0.0f);     gl11.glvertex3f(50.0f, -50f, -50f);     gl11.glvertex3f(-50.0f, -50f, -50f);     gl11.glvertex3f(-50.0f, 50f, -50f);     gl11.glvertex3f(50.0f, 50f, -50f);      gl11.glcolor3f(0.0f,0.0f,1.0f);     gl11.glvertex3f(-50.0f, 50f, 50f);     gl11.glvertex3f(-50.0f, 50f, -50f);     gl11.glvertex3f(-50.0f, -50f, -50f);     gl11.glvertex3f(-50.0f, -50f, 50f);      gl11.glcolor3f(1.0f,0.0f,1.0f);     gl11.glvertex3f(50.0f, 50f, -50f);     gl11.glvertex3f(50.0f, 50f, 50f);     gl11.glvertex3f(50.0f, -50f, 50f);     gl11.glvertex3f(50.0f, -50f, -50f);      gl11.glend();     gl11.glpopmatrix(); }

looks me depth issue. front of cube off front of frustum , getting clipped out.

gl11.glortho(0, display.getdisplaymode().getwidth(), 0, display.getdisplaymode().getheight(), -1, 1);

notice 1 (last param), past clipped out.

what seeing in effect section of cube stretched out.

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...
