Hi, I guess you have a designer. If so, just add a button from the designer and just connect it to a slot as the following;


connect( yourClearButton,
SIGNAL(clicked()),
this,
SLOT(clearButtonClickedSlot()) );

and just implement the SLOT


void Foo::clearButtonClickedSlot()
{
mUi->yourLineEdit->setText("");
}

void Foo::clearButtonClickedSlot()
{
mUi->yourLineEdit->setText("");
}
in this case you can simply use one connection


connect( yourClearButton,
SIGNAL(clicked()),
mUi->yourLineEdit,
SLOT(clear()) );

;)

but I think author needs clear-button like aamer4yu suggested.

Oh I didn't know the clear thing..you're right.

By the way, right about the last comment of yours as well I guess.

Sorry..that is not the case. I am asking about how to add a clear button to a QLineEdit using cascading style sheets. So that I can display the clear button on the lineedit in the hover state.

You will need to make your custom widget.
Also the link I gave before,, the code link seems to be invalid now...:(
