ui not declared in scope

[Zlatomir]

That is most likely because you don't have a ui member object or pointer or not inheriting from the ui auto-generated class.

See here the methods for using ui in the cpp file (i recommend the private member or pointer <don't forget to new the ui* if you use a pointer>)

Form1::Form1():QMainWindow(NULL,0)

It should be like this.....
ui(new Ui::QtMySql)

@Gokulnathvc: the only problem with the line you pointed to is that is doesn't take a parent and pass is to the QMainWindow constructor:

Form1::Form1(QWidget* parent = 0) : QMainWindow(parent, 0)

Form1::Form1(QWidget* parent = 0) : QMainWindow(parent, 0)

@Steve: the main problem is that he forgot to integrate the generated code, he only included the header ui_form.h:

#include "ui_form.h"
 
class Form1:public QMainWindow
{
Q_OBJECT
public:
	Form1();
	~Form1();
 
protected slots:
        void function1();
//this needs to be added:
private:
        Ui_Form ui; //object or pointer whatever you prefer
//      or you can use the class from Ui nanespace:
//      Ui::Form ui; 
//      read the documentation page linked in my previous post
}

#include "ui_form.h"

class Form1:public QMainWindow
{
Q_OBJECT
public:
	Form1();
	~Form1();

protected slots:
        void function1();
//this needs to be added:
private:
        Ui_Form ui; //object or pointer whatever you prefer
//      or you can use the class from Ui nanespace:
//      Ui::Form ui; 
//      read the documentation page linked in my previous post
}
