I am in the main dialog head file that the object of the child dialogs

In my child dialogs CPP document stating the main header file dialog box, and then in a child dialogs CPP file call this object, prompt the undefined identifiers

Bosses: can you help me, please

CodePudding user response:

You this is two class definition file, in the main dialog in # include file to open the dialog class header file, then define a dialog object

CodePudding user response:

To have an understanding of object-oriented programming ideas, this should be first to obtain the main dialog again on the object operation, the definition of the object belongs to the main dialog,
