title: sencha GXT css classes
body: <p>i'm having problems with styling grid in gxt, the thing is that the elements in the grid get (i don't know how exactly) css class named ".GKA1XC4LIC" and this class overrides the settings, provided by my own css class (in my own css file). However some properties (like font-size) i'm able to change with my class (i mean my css file is being loaded).</p>
  
  <p>i guess this .GKA1XC4LIC class is generated somewhere i don't know where. Why it is done this way? Am i doing this completely wrong?</p>
  
  <p>i set class name like this:</p>
  
  <pre><code>codeColumnConfig.setColumnTextClassName("smk-grid-text");
  </code></pre>
  
  <p>thanks</p>
