pushButton click event

hii..
I'm facing difficulty while using pushbutton click Event.
Here is the code:

Code:

---

connect(ui.pushButton, SIGNAL(clicked()), this, SLOT(some_slot()));

---

I want the function to be access when the some_flag is TRUE;
The flag is set TRUE else where in the code & initially the flag is FALSE.
How can it be done?

I'm not sure that I understand what your question properly, but maybe this can help

Code:

---

void MyWidget::some_slot()
{
    if (!m_someFlag)
        return;
    ...
}
