Fitting signals to slots in Qt

I'm trying to enable a QPushButton after another QPushButton is clicked and I've run into a problem. The first QPushButton can emit a clicked() signal while the second QPushButton only has slots of the form setEnabled(bool) and setDisabled(bool).

Basically, I'm trying to do

connect(ui->pbViewVolume,  SIGNAL(clicked()), 
        ui->pbSaveAsImage, SLOT(setEnabled(true)));

Since it's not possible to send a signal with fewer parameters than the slot, how can I best do this? The only way I see is to create a public slot for my MainWindow like

void EnableSaveAsImageButton(){
    ui->pbSaveAsImage->setEnabled(true);
}

but I'd rather not fill my MainWindow with this sort of rubbish function.

  1. You have to create that slot.
  2. You don't need to make that slot public, make it private.
  3. This function is not rubbish.
