Is like that, I now encapsulates a display window and wrote a toolbar window to window, and then the two interface encapsulated into a dynamic library export:

 
M_pGraphicsWidget=new GcImageWidget (this); 
M_pToolBox=new GcImageWidgetToolBox (m_pGraphicsWidget, this); 
////
M_mainlayout=new QGridLayout (); 
M_mainlayout - & gt; AddWidget (m_pToolBox, 0, 0); 
M_mainlayout - & gt; AddWidget (m_pGraphicsWidget, 0, 1); 

SetLayout (m_mainlayout); 

By setting up the layout, let the toolbar and view window can be created out
Then I created a dialog box to call the library, and create the object when structure (test the Demo I did not write here shows what)

 m_ImageView=new GcGraphicsWindow (this); 

Then I close the dialog box will collapse ~ ~ ~ ~ ~ and then debugging found has been the destructor collapse when the object ~ ~

I put the rolls all NEW blocked inside structure, the construction of an empty, empty destructor, that is, when the external NEW just create a window, or collapse, it seems has nothing to do with the window class and toolbar below

CodePudding user response:

Feel is static library is a problem with the link you call? Call the library to return the object's memory is being invoked the DLL in opening up the main process of release resources will have a problem

CodePudding user response:

refer to the second floor mango black response:

solved now, when I was in the main program destructor initiative to Delete this object, then the air line/; But still think impassability, automatic destructor call module destructor will collapse ~ ~ ~ ~
