[Rekha]

i have zipped the sample.h file as u had asked..i have attached sample.cpp also along with that

ok here it is

};

To copy to clipboard, switch view to plain text mode 

But I would not suggest you to do this way. Please look into Qt examples as on how the classes are designed.

[Rekha]

its not working .. please say me
1)the code to copy all the characters from the text box to list box when a push button like enter is being clicked after entering all the characters in the text box....... is not working

[munna]

I have tested this and it works perfectly for me. When I click on the enter button the text gets copied to the list1.

Ofcourse u'll need to add

#include<QObject> in the beginning

and

namespace Ui {
class Dialog: public Ui_Dialog {};
} // namespace Ui


at the end

[Rekha]

on executing "make" command i'm getting the follwoing errors..
wat 2 do?

MyDialog.cpp: In member function `void MyDialog::copy()':
MyDialog.cpp:16: error: `addItem' undeclared (first use this function)
MyDialog.cpp:16: error: (Each undeclared identifier is reported only once for
each function it appears in.)
make: *** [MyDialog.o] Error 1
