Function Call from Signal Slot

[praveen0991kr]

Dear All,

 I am trying to access one fuction that I have defined in class let Say "Class A" 

and trying to call from "class B" from signal slot ;

@
I am able to connect with in the Class A;
like wise:
connect(ui->UpdatScr,SIGNAL(selectionChanged()),this,SLOT(OpenKeypad()));

@

But how to connect :

@

from Class A;

from connect(ui->updtScr,SIGNAL(selectionChanged()),"To-other-classB",SLOT(Class-B-function-Name))); ???

@

Pls Provide some sample from code if possible I will be very thankful to you;

Thank You

Regards

Praveen

You need to have the pointer to an object of that other class and pass it in place of "this".

Hi ,
Thanks for reply ;

What I have tried;

in .h file;

@
Keypad *mKeypad;
@

in .c file;

@
connect(ui->UpdatScr,SIGNAL(selectionChanged()),,myKeyPad,SLOT(OpenKeypad(1,1,1,1,1);));
@

OpenKeypad(int,int,int,int,int) is fuction defined in Keypad class;

but it didnt worked Is I am make any mistake;

Thanks for reply

You need to instantiate the object using "new". I recommend reading a book on C++ or Qt before proceeding further, it will make it easier for you.
