title: Remove selection around QPushButton text
body: <p>When i add QPushButton on my form, i get this:</p>
  
  <p><img src="https://i.stack.imgur.com/wT3rB.png" alt="enter image description here"></p>
  
  <p>You can see ugly text selection (into the button). How can i remove it?<br>
  Here is my CSS of this button:</p>
  
  <pre><code>    enterButton-&gt;setStyleSheet("QPushButton { \
                                      padding: 6px; \
                                      background: #369; \
                                      color: white; \
                                      font-size: 13px;\
                                      border: 0; \
                                      border-radius: 3px; \
                                  }\
                                  QPushButton:hover { \
                                      background: #47a; \
                                  }\
                                  QPushButton:pressed { \
                                      background: #58b; \
                                  }");
  </code></pre>
  
  <p>Thanks!</p>
