title: How to set Stylesheet for only one side of border in QLineEdit and QPushButton?
body: <p>I tried to create a combo box manually. So a line edit should be combined with a (dropdown) push button. Therefore I want to hide the right border of line edit and left border of push button.</p>
  
  <p>I tried with this:</p>
  
  <pre><code>myLineEdit-&gt;setStyleSheet("QLineEdit{border-right: none;}");
  myPushButton-&gt;setStyleSheet("QPushButton{border-left:none;}");
  </code></pre>
  
  <p>I also tried with:</p>
  
  <pre><code>myLineEdit-&gt;setStyleSheet("QLineEdit{border: 1px 1px 0px 1px;}");
  </code></pre>
  
  <p>But both did not work. Where am I wrong?</p>
