Run-time objects and CRuntimeClass
-
Hi there ! I made a few searches through the articles and through the board, but didn't manage to find an answer.. If there is already an answer to this, just post the link :) So, I have a CCtrlView-derived class, CTabView (No, not a co-incidence). This class is responsible for upkeeping a Tab control (Created through CCtrlView's constructor) and an array of CViews. Now, when you wish to add a new view to the tab, it requires you to insert a pointer to your CView-derived class through the RUNTIME_CLASS-macro. After that, it checks if the run-time info you specified is indeed a CView-derived, and creates a new object based on this info with CRuntimeClass::CreateObject. When the creation is done, it creates and attaches a new view to this object by casting a pointer to the CView-class and calling it's Create-method. Then, it saves the CView-pointer to a CObList for further use. When quitting, the application goes through the list and calls each CView's DestroyWindow in succession until the list is clear. After that, it posts a OnDestroy-message to the underlying CCtrlView which destroys the tab control. But the problem is that when I build & run this app, it works smoothly until the quit phase. There, it causes an assertion. What am I missing here ? Should I use 'delete' on each of the pointers after DestroyWindow as well ? Can it be done ? What, exactly, does CreateObject do when it builds an object from the run-time info ? And if 'delete' is not the answer, what is ? Or shouldn't I delete the views at all, but let "The Framework" work it out ? Of course, if someone already has a functioning Tab control which accomplishes the above mentioned smoothly, a link is again appreciated :) Thanks in advance, Antti Keskinen EDIT: The 'delete' operation did no good, the app still asserts. For additional info, I am using a splitter window to where my derived control view is loaded to. Debugging reveals it is XTreme toolkit's CXTPFrameWnd, which causes the assertion. ---------------------------------------------- The definition of impossible is strictly dependant on what we think is possible.
