title: Problems with QML cross-platform designs: text sizes
body: <p>I've been having trouble with different OSs (tried Windows 7 and Ubuntu 13.10) having different font widths and heights. I tried setting pixelSize and pointSize and both results in different sizes in both Arial and Courier font texts (Windows fonts are generally bigger).</p>
  
  <p>Here is an example:</p>
  
  <pre><code>Rectangle {
      width: 312
      height: 44
  
      Text {
          id: text_1
          text: qsTr("1234567890123456789012345678901234567890")
          anchors.top: parent.top
          anchors.left: parent.left
          anchors.right: parent.right
  
          font.family: "Courier"
          font.pointSize: 10
      }
      Text {
          id: text_2
          text: qsTr("123456789012345678901234567890")
          anchors.top: text_1.bottom
          anchors.left: parent.left
          anchors.right: parent.right
  
          font.family: "Courier"
          font.pointSize: 10
      }
      Text {
          id: text_3
          text: qsTr("12345678901234567890123456789012345")
          anchors.top: text_2.bottom
          anchors.left: parent.left
          anchors.right: parent.right
  
          font.family: "Courier"
          font.pointSize: 10
      }
  }
  </code></pre>
  
  <p>This rectangle's width and height are defined by trial and error to fit the 3 text's in Ubuntu. See screenshots below:</p>

  <p>In my application, I'd like one text object (with Courier font) to fill it's parent's width (text is fixed). In another rectangle, I'd like the text objects (more than one, anchored just like in the example above, with Arial font) to fill the parent's height.</p>
  
  <p>Currently, I'm looking for a way to set the parent's width and height dynamically, calculated from the fixed text content, but I can't shake the feeling there's got to be a simpler way to do this.</p>
  
  <p>Any tips are appreciated.</p>
