button - Fitting signals to slots in Qt -

I enable a QPushButton after another QPushButton Trying to click and I have participated in a problem first QPushButton one clicked () can remove the signal, while the second QPushButton has only the setEnabled (bool) slots and set to disable (boole) .

Actually, I am trying to do

  connect (ui-> pbViewVolume, signal (clicked)), UI-> pbSaveAsImage , Slot (setEnabled)));   
 Since it is not possible to send a signal with less parameters compared to the slot, how can I do this? My only way is my  main window  like  
  zero EnableSaveAsImageButton () {ui- & gt; PbSaveAsImage-> To create a public slot for setEnabled (true); }   
 But I will not fill my  main window  with functions of this type of garbage.   
 
 
 You do not need to make this slot public, make it private.  "Post-lesson" itemprop = "text"> 
 
 You have to create that slot.  
 This function is not garbage.
