Title:
Subsequent closing of windows results in small untitled icons in
launcher
Status in Unity:
Incomplete
Status in unity package in Ubuntu:
Incomplete
Bug description:
I have an application that creates and destroys a large amount of
windows. If a lot of windows have to be closed simultaneously, then a
number of "untitled window"-icons remain in the launcher. These icons
can't be removed from the launcher until you log off.
Here's a code-snippet underneath which produces this behaviour:
#include <opencv/highgui.h> // includes highGUI definitions
int main(int argc, char *argv[])
{
const int PlayDelay = 500; // msec
const char Escape = 27; // ascii-code
CvSize FrameSize;
FrameSize.width = 640;
FrameSize.height = 480;
IplImage* ImageOI = cvCreateImage(FrameSize,IPL_DEPTH_32F,3);
cvZero(ImageOI);
std::vector<std::string> WindowNames;
const int NumberOfWindows = 30;
for (int i=0;i<NumberOfWindows;i++)
{
std::stringstream NameTestWindow;
NameTestWindow << "Test";
NameTestWindow << "-" << i;
WindowNames.push_back(NameTestWindow.str());
}
while (true)
{
for (int i=0;i<NumberOfWindows;i++)
{
cvShowImage(WindowNames[i].c_str(),ImageOI);
}
char c = cvWaitKey(PlayDelay);
for (int i=0;i<NumberOfWindows;i++)
{
cvDestroyWindow(WindowNames[i].c_str());
}
if (c == Escape ) break;
}
cvReleaseImage(&ImageOI);
return 0;
