QGridLayout: change height of a row
<p>I'm new at qt and now my window looks like this:</p>

<pre><code>*---------* *---------* *---------* *---------* 
|ListView1| |ListView2| |ListView3| |ListView4| 
|         | |         | |         | |         |
*---------* *---------* *---------* *---------* 
*---------------------------------------------*
|                                             |
|                  ListView5                  |
|                                             |
*---------------------------------------------*    
*---------------------------------------------*
|                  GridLayout2                |
|                                             |
*---------------------------------------------*
</code></pre>

<p>The problem is that second row (ListView5) is higher than first and third rows, while I want first row to be higher than third row, which should be higher than second row. Is there a way to do it? Or should I use something else insted of gridlayout? Thanks.</p>
