Hi
If I remove a tab then add it again the windowmanager throws an AlreadyExistsException, even though i destroy the tabwindow.

Code: Select all

CEGUI::Window* defaultwin=CEGUI::WindowManager::getSingleton().createWindow((CEGUI::utf8*)&quot;DefaultWindow&quot;,(CEGUI::utf8*)&quot;Test1&quot;);

tabCtrl-&gt;addTab(defaultwin);

....

tabCtrl-&gt;removeTab(defaultwin);
CEGUI::WindowManager::getSingleton().destroyWindow(defaultwin);
...

CEGUI::Window* defaultwin2=CEGUI::WindowManager::getSingleton().createWindow((CEGUI::utf8*)&quot;DefaultWindow&quot;,(CEGUI::utf8*)&quot;Test1&quot;);

tabCtrl-&gt;addTab(defaultwin2); // error thrown

I recon this has something to do with the TabButton (error log: Exception: WindowManager::createWindow - A Window object with the name 'btnTest1' already exists within the system. ) but I haven't been able to resolve the problem. I tried destroying the button in TabControl::removeButtonForTabContent but this turned out to be the wrong place

Maybe I'm doing something wrong with deleting the tab? Any hints where I should look?

Cheers
Tom
