QT Signal and Slot between windows -


i want connect windows in qt.

i know how connect 2 widgets in same window.

using qobject::connect() in ui_a.h;

but now, have 2 windows.

six files.

for example:

ui_a.h(window a)

a.h a.cpp (widget in window a)

ui_b.h(window b)

b.h b.cpp (widget in window b)

how connect 2 widget in different windows?

thank you.

you have find scope of both window object , connect them there. perhaps connecting them main.cpp make easier. example,

qapplication a(argc, argv); a; b b; qobject::connect(&a, signal(somesingal()), &b, slot(someslot())); qobject::connect(&b, signal(anothersingal()), &a, slot(anotherslot())); a.show(); b.show(); return a.exec();

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
