I am doing something like this:

    void addTab() {
	WithTabLay<ParentCtrl> *tabLay  = new WithTabLay<ParentCtrl>();
        CtrlLayout(*tabLay);
        tabLay->HSizePosZ(0, 0).VSizePosZ(0, 0);
        tabs.Add(*tabLay, MyImgs::add20(), "Tab1");
        
        tabLay->closeBut.WhenPush = [=] { 
        	tabs.Remove(*tabLay); 
        	tabLay->~WithTabLay();
        	delete tabLay;
        };
    }


As you can guess,
WithTabLay is the tab layout created in the UI editor.
closeBut is a button within the tab that I want to use to remove the tab.

Question-1: Is it necessary to call the destructor after removing the tab?
tabLay->~WithTabLay();

Question-2: Is it necessary to delete the allocated memory? This line causes the applicatton to crash. So probably I should not, if so, how can I free the allocated memory?
delete tabLay;

Questions-3: Is there any better way to do this without using pointers? If I create the Tab on stack, its free'ed at the end of the function (from RAII I suppose). And the Tab will not be visible.
