title: Qt - How to disable QCheckBox while retaining checked state?
body: <p>I have a dialog with two checkboxes, let's call them A and B. When A is NOT checked, B should be able to be toggled as the user desires. When A IS checked, B should not be able to be toggled. Right now I have the following in my constructor function for the dialog:</p>
  
  <pre><code>connect(ui-&gt;A, SIGNAL(toggled(bool)),
          this, SLOT(setBCheckable(bool)));
  </code></pre>
  
  <p>...and then I have that function as this:</p>
  
  <pre><code>void MyClass::setBCheckable(bool AChecked)
  {
      if(AChecked)
      {
          ui-&gt;B-&gt;setCheckable(false);
      }
      else
      {
          ui-&gt;B-&gt;setCheckable(true);
      }
  }
  </code></pre>
  
  <p>However, when I do this, I've noticed that when I click A, B will APPEAR to retain it's status, but then when I move the mouse over it (whether A is still clicked or not, just the next time I mouse over after checking A), it refreshes B to NOT being clicked. I cannot have it doing this, since I need the function to retain the value for B even when B cannot be changed. Is there a way to do this? To summarize, I need a way for a QCheckBox to keep it's checked status even when the button cannot be toggled. Thanks in advance!</p>
