Q: Ce este o fereastra overlapped?

A: O fereastra overlapped este o fereastra top-level care are bara de titlu, border si zona client.
Este creata specificand stilul WS_OVERLAPPED in functia CreateWindow sau CreateWindowEx.

Note

ferestrele overlapped sunt in general utilizate ca fereastra principala a aplicatiei;
constanta WS_OVERLAPPED este definita in winuser.h si are valoarea 0 (zero);

in practica, in loc WS_OVERLAPPED de se utilizeaza stilul compus WS_OVERLAPPEDWINDOW; acesta adauga un border pentru dimensionare (sizing border), menu sistem, cat si butoane de maximizare si minimizare;

Code: Select all

#define WS_OVERLAPPEDWINDOW (WS_OVERLAPPED     | \
                             WS_CAPTION        | \
                             WS_SYSMENU        | \
                             WS_THICKFRAME     | \
                             WS_MINIMIZEBOX    | \
                             WS_MAXIMIZEBOX)
