java - Action event on a JButton matrix -



java - Action event on a JButton matrix -

i can't handle event in matrix of jbuttons. need figure out button pressed, alter objects color match button.

i using code:

private class matrixbuttonlistener implements actionlistener { public void actionperformed(actionevent e) { jbutton btn = (jbutton) (e.getsource()); (int = 0; < matrixbouton.length; i++) { (int j = 0; j < matrixbouton[i].length; j++) { btn.equals(matrixbouton[i][j]); if (btn.getbackground() == color_neutral) { btn.setbackground(color_player); } } } } }

instead of looping through jbuttons trace button using evt.getsource(). homecoming reference actual button pressed. , can perform wish. can utilize next simplified code indeed:

private class matrixbuttonlistener implements actionlistener { public void actionperformed(actionevent e) { jbutton btn = (jbutton) (e.getsource()); if (btn.getbackground() == color_neutral) { btn.setbackground(color_player); } } }

java swing jbutton actionlistener

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
