Nested pop ups

Utkarsh Agarwal

When I make a new pop up and show it using show() or exec() after clicking a button, can I use the buttons on the pop ups as well? Basically can I use nested pop ups?

Hi and welcome to the forums
When you say "popup" do you mean dialog or what kind of widget ?
But yes, in most situations you can.

@mrjj I meant dialog. Also I figured out my mistake but I don't know how to fix it.

The reason it isn't working for me is because I haven't included Q_OBJECT in any of the header files except the first one. This is why my signals aren't working. I understand a simple solution to that would be to include Q_OBJECT in each header file but that shows different kind of error. Specifically it says the following errors

undefined reference to 'NewAccount::staticMetaObject'

What can I do?

For you better understanding, I am writing a pseudo code below :

//Header File for newaccount.h
#include <QDialog>

class NewAccount : public QDialog
{
Q_OBJECT
};

//Header File for userinfo.h
#include <QDialog>
#include "newaccount.h"

class UserInfo : public QDialog
{
Q_OBJECT

protected : NewAccount *new;
};

Hi
Make sure that all the classes are defined in .h file. ( not defined in any .cpp )
Then completely clean your build folder. qamke + rebuild all.

This error i have seen mostly with the moc tool not find the class or the
unit was not recompiled after adding Q_OBJECT.
