Issue with getWindowProperty(cv::WND_PROP_VISIBLE) #22595
Description
Hi I have a issue with getWindowProperty(cv::WND_PROP_VISIBLE) always returns -1
Here the example code:
int main(int argc, const char * argv[]) {
cv::namedWindow("test");
cv::Mat image = cv::imread("/Users/thewoz/Desktop/img.png");
printf("%f\n", cv::getWindowProperty("test", cv::WND_PROP_VISIBLE));
cv::imshow("test", image);
printf("%f\n", cv::getWindowProperty("test", cv::WND_PROP_VISIBLE));
cv::waitKey(0);
printf("%f\n", cv::getWindowProperty("test", cv::WND_PROP_VISIBLE));
return 0;
}
Turning on Mac it returns -1, -1, -1 on linux instead it returns 1, 1, 1 which seems to me to be correct.
Does anyone know how that happened?
