qt - QRubberBand colour isn't changed under Mac -



qt - QRubberBand colour isn't changed under Mac -

this code draws qrubberband in bluish colour under windows doesn't work under macos. , wonder why?

qrubberband *rubberband = new qrubberband(qrubberband::rectangle, this->imagelabel); rubberband->setgeometry(rec); qpalette palette; palette.setbrush(qpalette::highlight, qbrush(qt::darkblue)); rubberband->setpalette(palette);

i've resolved way:

qrubberband *rubberband = new qrubberband(qrubberband::rectangle, this->imagelabel); rubberband->setgeometry(rec); qpalette palette; qcolor color(qt::blue); color.setalpha(80); palette.setbrush(qpalette::highlight, qbrush(color)); rubberband->setpalette(palette);

now rubberband same under macos , windows.

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...
