2013-03-26 14:17:08 -0600 | commented answer | Destroying Windows in Separate Functions Ahhh, so silly of me. I forgot to return an exit code from runProcessing() and check the exit code to break the for loop. Thank you for the assistance. |

2013-03-26 13:36:15 -0600 | asked a question | Destroying Windows in Separate Functions Hi everyone, This may seem like a newbie question but I hope I can get some assistance with this problem I'm having. I have an initialize function that sets up my cvCapture object to start capturing from a video file named initialize(). The cvCapture object named capture is created as a global variable just for testing purposes. I have one function that creates three windows named A,B and C and this function does some processing with the windows showing their progress. Let's call this function runProcessing() I want to destroy windows A,B and C in a separate function named releaseMemory() after runProcessing() has executed. However, when I try to call cvDestroyWindow() or cvDestroyAllWindows(), the program freezes and does not terminate correctly. How do I go about destroying the windows properly seeing that they are created in another function instance in order to correctly exit my program? Example source code: |
