Can we call a python method from java? -


this question has answer here:

i know jython allows call java method java's classfile if written python, reverse possible ???

i have many algorithms written in python, work pretty python , jython lack proper gui. planing bring gui java , keep python library intact. not able write gui jython or python , cannot write algorithm python. solution found merge java's gui , python's library. possible. can call python's library java.

yes, can done . done creating pythoninterpreter object , calling python class using .

consider following example :

java : 

import org.python.core.pyinstance;   import org.python.util.pythoninterpreter;     public class interpreterexample   {       pythoninterpreter interpreter = null;        public interpreterexample()      {         pythoninterpreter.initialize(system.getproperties(),                                      system.getproperties(), new string[0]);          this.interpreter = new pythoninterpreter();      }       void execfile( final string filename )      {         this.interpreter.execfile(filename);      }       pyinstance createclass( final string classname, final string opts )      {         return (pyinstance) this.interpreter.eval(classname + "(" + opts + ")");      }       public static void main( string gargs[] )      {         interpreterexample ie = new interpreterexample();          ie.execfile("hello.py");          pyinstance hello = ie.createclass("hello", "none");          hello.invoke("run");      }   }

python :

class hello:       __gui = none        def __init__(self, gui):           self.__gui = gui        def run(self):           print 'hello world!'

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...
