title: How to prevent widgets from expanding to whole box (GTK 2)
body: <p>I'm having the following issue with GTK2:</p>
  
  <p>I created two buttons with labels inside an horizontal box. (I intend to pile several hboxes)
  However there's an issue: When I make the box_pack functions they go like this:</p>
  
  <pre><code>gtk_box_pack_start(GTK_BOX(hbox1), button1, FALSE, FALSE, 0);
  gtk_box_pack_start(GTK_BOX(hbox1), button2, FALSE, FALSE, 0);
  </code></pre>
  
  <p>Despite putting them both false, the buttons still expand vertically, making the "hbox1" ocupy all the space that is left on the parent box. I want the buttons to expand only to the minimum height required for the label to be displayed properly (like it usually happens on vertical boxes).</p>
  
  <p>I heard that in GTK3 you could use the <strong>gtk_widget_set_vexpand</strong> and <strong>gtk_widget_set_hexpand</strong> functions. However, these do not seem to exist in GTK2, as they are on recognized....</p>
  
  <p>Any solution for this? 
  (Not just this case with horizontal boxes, but with the respective case in vertical boxes)</p>
