Description

If i create two windows

namedWindow("Input", CV_WINDOW_AUTOSIZE | CV_WINDOW_FREERATIO);
namedWindow("Output", CV_WINDOW_AUTOSIZE | CV_WINDOW_FREERATIO);

I load a video into both windows and play it

If i put the mouse over the save icon in the second window the program crashes

Actually its any icon in the second window crashes it

To see the problem use the provided qt sample. The window named original is the one that crashes it on mouseover of any of the icons.

Hello,

I cannot reproduce the bug. On my side (XP + VS2008 + OpenGL), the sample does not crash when I use the icons (I tested all the icons on both window). To be sure we use the same code, I deleted the source and the sample and checkout everything again from repository. Could you give me more information ?

Thanks

Yannick
PS: Do you know is the bug #531 is fixed ? - ticket still open.

Could you confirm to me this is crashing when you use the icons (does not crash for me)

CvCapture* video = cvCaptureFromFile("cube4.avi");
    CV_Assert(video);
namedWindow("Input", CV_WINDOW_AUTOSIZE | CV_WINDOW_FREERATIO);
    namedWindow("Output", CV_WINDOW_AUTOSIZE | CV_WINDOW_FREERATIO);
    IplImage* source=0;
while(cvWaitKey(33) != 27)
{
        source=cvQueryFrame(video);
        cvShowImage("Input",source);
        cvShowImage("Output",source);
    }
    cvReleaseCapture(&video);

Thanks;

The above code does crash it on my system, I did a fresh checkout and build

If I move my mouse over any of the icons in the output window it crashes

Yesterday, I did a function to disable the button when no bar is attached to the properties window. I commented it for now. Could you try again after checkout ?

Thanks

Hello,

Sorry to ask you to test again. I should have fixed Ticket #533 and Ticket #532 ^^.
Look like the modification from yesterday crashed the code. Thus I did the 'disable button when no bar' another way. The shortcuts work with CV_GUI_NORMAL again.

Thanks a lot for your help,

Yannick

Changeset r3542 does not fix this issue for me, putting the mouse over any icon crashes the program.

I did a clean checkout and fresh build.

Hello,

looks like I start to understand what is going on. The toolTip (yellow box) attached to the icon may be the reason.
Can you test again with the new version.

Thank.

Yes, you were correct, it was the toolTip that was causing the crash.

Confirmed fixed in r3544

Thanks :)
