title: QT: How do I raise/lower value of label depending on value of SpinBox
body: <p>First let me say, I'm new to QTCreator. I have the UI setup for all of the following just can't figure out how to properly connect the signals and slots:</p>
  
  <p>Ok,so here is my problem. I have 5 SpinBoxes all with a max value of 10 and minimum value of 0, all of which start at 0 . I have a label with the value of 25. When I change the value of the spinbox with the +/- buttons, I want the label to either subtract or add back too the label of 25. In addition, once the value of 25 reaches 0 I want all spinboxes disabled for adding.</p>
  
  <p>(Unfortunately, since I set this all up using the Form creator, all the code is default.</p>
  
  <p>Example:</p>
  
  <pre><code>Label: 1
  SB1: 5
  SB2: 10
  SB3: 2
  SB4: 6
  SB5: 1
  </code></pre>
  
  <p>All the values of the SpinBoxes equal 24. When the plus button is hit the value will be 25 for all boxes. Thus I want all the + buttons disabled and when the - button is pressed, I want the enabled.</p>
