QButtonBox, how to find index of QDialogButtonBox::Ok

[HappyCoder]

Hi,

i have in one of my form class a QButtonBox and i wand to change the text from "OK" to "Export" (translatable).

1) The easy way is to search for the QString "OK", but if i activate other languages it is not "OK" anymore.
2) An other easy way is to use a fixed indexOfOk, "try and error method" till i have the right index to OK Button, but it is not very flexible

I use this so far:



// change "OK" to "Export"
QList<QAbstractButton *> buttonList = ui->buttonBox->buttons();
int indexOfOk = -1;
for( int i=0; i<buttonList.size(); i++ )
{
if ( ? ) // how must my if looks like
{
indexOfOk = i;
break;
}
}
if( indexOfOk != -1 )
ui->buttonBox->buttons().at( indexOfOk )->setText(QString("Export"));


QButtonBox::buttons() gives me a QList<QAbstractButtons *>.
I can't find any relation between QAbstractButton and QDialogButtonBox::Ok ( Widget vs. enum )?

Thx

Read about QDialogButtonBox::button(StandardButton which)

Thx, here is the solution:



// change "OK" to "Export"
QList<QAbstractButton *> buttonList = ui->buttonBox->buttons();
int indexOfOk = -1;
for( int i=0; i<buttonList.size(); i++ )
{
QDialogButtonBox::StandardButton stdButton = ui->buttonBox->standardButton( buttonList.at(i) );
if ( stdButton == QDialogButtonBox::Ok)
{
indexOfOk = i;
break;
}
}
if( indexOfOk != -1 )
ui->buttonBox->buttons().at( indexOfOk )->setText(QString("Export"));

#2 only works if "OK" is the standard button of the dialog, IMO it doesn't work if you want to
change "retry" or "cancel" etc., my solution is a general way i guess.

No, it works regardless of which button is the default.

Yes, it does.

It is no more generic, just less efficient and with more unnecessary code.

Ok, i think i got it :)



ui->buttonBox->button( QDialogButtonBox::Ok )->setText( tr("Export"));

[anda_skoa]

Exactly!

Way shorter and simpler, wouldn't you agree? :)

And so it will be safer when there is no button :
QPushButton *ptr = ui->buttonBox->button( QDialogButtonBox::Ok );
if( ptr )
ptr->setText( tr("Export"));
