You can't do these from within Designer. Use either multiple (http://doc.trolltech.com/4.2/designer-using-a-component.html#the-multiple-inheritance-approach) or single inheritance (http://doc.trolltech.com/4.2/designer-using-a-component.html#the-single-inheritance-approach) approach and create custom slots for doing those tasks.

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

void MyForm::newItem()
{
ui.listWidget->addItem(ui.lineEdit->text());
}

In the same way, just create a custom slot connected to the button's clicked() signal and do the task by hand:

connect(ui.someButton, SIGNAL(clicked()), this, SLOT(deleteItems()));

void MyForm::deleteItems()
{
qDeleteAll(ui.listWidget->selectedItems());
}



n one thing more in previous query...when we click the pushbutton then line edit text item inserted in list as well as line_edit should be clear n ready to get the next item (i.e insertion for next item)......
QLineEdit::clear()

ui.lineEdit->clear();
