@Zunneh
I shall be surprised if someone can discern exactly what you are saying here....after this i called this object from another program (it work )
What does that mean? You can't call objects from other programs....
i created a function in this new class to move my object (i used move which come from QLabel )
So your code does not move the object (
Personnage
), it just moves the label within thePersonnage
widget.... To be specific, yourtest->move(0, m_y)
moves theQLabel
within your widget, while thethis->move(60, 0)
moves yourPersonnage
, which one were you talking about...?but it didn't work
What does that mean...?

i created the main program with Qt designer and after this i added a class in this project which contains the green ball , now from the main program (look at the previous screen shot ) i created the object (the green ball whose name is bat) and i want to control this object from main program , i tried but i can' move the object from the main program (i can move it only from the constructor of the class with test->move , me i want to move all the new object Personnage for example when i write bat->movetoUp() it move the object to Up
")

bat
is local to the constructor so can't be referenced outside it. move thePersonnage* bat;
definition in the header (.h) and in the constructor just putbat = new Personnage(this);
. Now you can usebat
everywhere in yourMainWindow
.P.S.
The constructor ofPersonnage
does some weird stuff, basically the label insidePersonnage
andPersonnage
have completely distinct lives and that's unusual to say the least -
i find the solutions , my problem that in the first i put QLabel who is inside Personnage the parent , now i put my Personnage the parent so i can move the personnage not the Qlabel inside the personnage, i added the command this->setParent(parent)
by the way thank you guys for the help
