Hi guys,
I can use the below code to display full screen in Windows and Linux. but in Mac OS X, it always have the menu bar in the top! Is it possible to display full screen in mac with opencv? any one have ideas of this?

Regards Andy

cvNamedWindow(CALIBRATE_FORM_NAME, CV_WINDOW_AUTOSIZE); cvSetWindowProperty(CALIBRATE_FORM_NAME, CV_WINDOW_FULLSCREEN, CV_WINDOW_FULLSCREEN); cvMoveWindow(CALIBRATE_FORM_NAME, 0, 0);

int screen_width = GlobalData::Instance()->GetScreenWidth();
int screen_height = GlobalData::Instance()->GetScreenHeight();
IplImage* img = cvCreateImage(cvSize(screen_width, screen_height), IPL_DEPTH_8U, 3);
cvZero(img);


//cvMoveWindow(CALIBRATE_FORM_NAME, 0, 0);
cvShowImage(CALIBRATE_FORM_NAME, img);

solved fullscreen but crashed! this is the code: I used opencv2.4.3 and have done like this link http://code.opencv.org/issues/2846

but still crased!

cvNamedWindow(WIN_NAME, CV_WINDOW_NORMAL);
cvSetWindowProperty(WIN_NAME, CV_WND_PROP_FULLSCREEN, CV_WINDOW_FULLSCREEN);
int screen_width = GlobalData::Instance()->GetScreenWidth();
int screen_height = GlobalData::Instance()->GetScreenHeight();
IplImage* img = cvCreateImage(cvSize(screen_width, screen_height), IPL_DEPTH_8U, 3);
cvZero(img);
cvShowImage(WIN_NAME, img);
sleep(1);
cvReleaseImage(&img);
cvDestroyWindow(WIN_NAME);
