title: MATLAB Slider Callback
body: <p>I created a MATLAB Gui using GUIDE. In that GUI I use sliders to set some parameters. I set some reasonable limit to the slider, but I want the user to be able to increase the value over that initial limit.
  For example the slider by default has the limits min 1 and max 10. If it is placed at 10 and the user clicks the arrow for increasing, I want to set a new value for max as 11.</p>
  
  <p>To be able to do so, I want to specify the type of user interaction within the sliders' callback function. I want to check, whether the user clicked the increasing button on the slider, and if so, in case the slider is at max value, I want to change the max property.</p>
  
  <p>Is there a way of getting this information about the user interaction?</p>
  
  <p>I recognized that, if the slider is already the maximum value, and the user clicks the sliders' button for increasing, the sliders' callback isn't called. It seems, that the callback function is only called, if the slider is actually moved. So I would guess there are seperate callback function for the different buttons of the slider and I would need to access these.</p>
