swing - JTextpane does not respect visibleEditorRect with java 8 -


run below code both java 6 , java 8, , see result. line breaks works within bounds of visibleeditorrect on java 6, on java 8 string overflow bounds. there workaround problem.

import java.awt.rectangle;  import javax.swing.jframe; import javax.swing.jtextpane; import javax.swing.plaf.basic.basictextpaneui;  public class textpanebug {  public static void main(string[] args) {     jframe f = new jframe() ;     jtextpane text = new bugtextpane() ;     f.add(text);     text.settext("mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm");     f.setextendedstate(jframe.maximized_both);     f.setvisible(true); }  static class bugtextpane extends jtextpane {     public bugtextpane() {                setui(new basictextpaneui(){             @override             protected rectangle getvisibleeditorrect() {                 rectangle r = super.getvisibleeditorrect() ;                 rectangle newr = new rectangle(r.width / 2 - 300 , r.height/2 - 300 , 600 ,600) ;                 return newr;             }             protected void paintsafely(java.awt.graphics g) {                 super.paintsafely(g);                 rectangle r = getvisibleeditorrect() ;                 g.drawrect(r.x,r.y,r.width,r.height);             };         }              );     } } }

i resolve problem reverting breaking behavior java 6 functionality. overwriting getbreakweight , getbreakspot methods copying java 6 in extention of labelview enough.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
