            <description><![CDATA[Qt examples too complex for starters?
I am certainly no guru but

	All 3 work with Qt SDK and are fun

	(1) QtFigs4: example of SAX, paintEvent(graphics) and collections
(2) Lottery: example of paintEvent(graphics), designer and collections
(3) calculator: example of paintEvent(graphics) and designer

	Sometimes the basic usage of these elements is difficult to 
extract from a complex example. (e.g. I seem to remember a &#8220;chart&#8221; example)

	I could create simpler examples but they would NOT be so much fun.]]></description>

            <description><![CDATA[What is the sequence to determine where in a large widget the current QScrollArea viewport exists?  I assumed that viewport()&#45;&amp;gt;x() and veiwport()&#45;&amp;gt;y() would give me the relative offsets where the view port starts in the larger base widget but I was mistaken.

	I catch mouse click events in the QScrollArea window, but I need the event x/y location to be normallized to the whole image, not simply relative to the current visable portion.

	Do I have to query the scrollbars or is there a more direct way?

	Thoughts?]]></description>

            <author>Power_user_EX</author>
            <description><![CDATA[Hi all .. I m new to Qt 4.7 programming using Qt Creator .. Have some questions :

	1) Whats the basic difference between Qt Quick Application / UI and Qt Widget based app (Qt Gui application) in terms of programming style and convensions ? The main difference I see it Quick App uses QML for GUI design while Qt Widget based app uses UI forms to design GUI using Drag and drop .. after this is a bit confusing for me.

	2) Can some 1 explain me this code :
class MainWindow : public QMainWindow
&#123;
&amp;nbsp; &amp;nbsp; Q_OBJECT
&amp;nbsp;
public:
&amp;nbsp; &amp;nbsp; explicit MainWindow&#40;QWidget *parent = 0&#41;;
&amp;nbsp; &amp;nbsp; ~MainWindow&#40;&#41;;
&amp;nbsp;
private:
&amp;nbsp; &amp;nbsp; Ui::MainWindow *ui;
&#125;;


	especially Q_OBJECT and explicit MainWindow &#40;QWidget *parent = 0&#41;;


	3) And this code :
MainWindow::MainWindow&#40;QWidget *parent&#41; :
&amp;nbsp; &amp;nbsp; QMainWindow&#40;parent&#41;,
&amp;nbsp; &amp;nbsp; ui&#40;new Ui::MainWindow&#41;
&#123;
&amp;nbsp; &amp;nbsp; ui&#45;&amp;gt;setupUi&#40;this&#41;;
&#125;
&amp;nbsp;
MainWindow::~MainWindow&#40;&#41;
&#123;
&amp;nbsp; &amp;nbsp; delete ui;
&#125;


	4) If I want to program the same using Qt Quick what will the difference in code style ?

	&#45;Regards ,

            <description><![CDATA[I am using Qt SDK 1.1.4.
Qt Creator 2.4.0
Based on Qt 4.7.4 (32 bit)
Built on Dec 16 2011 at 03:25:42

	Currently my qt SDK is up to date.
I was very happy when I found the document Programming with Qt Quick for Symbian and MeeGo Harmattan Devices  version 1.1 released December 13, 2011. This is the latest version I could find.
I have downloaded it and try to follow it. Then I got disappointed.
The guide can be downloaded from this link
http://qt.nokia.com/learning/guides/

	When I create Hello World as described in chapter 2 Using Qt Creator to Setup the Project
there are many differences from my code and code explained in the PDF document.
I am new to Qt and this is confusing me.
1. In my code which is auto generated when I create new Qt Quick project top level element of the main.qml file is pageStacWindow. In your documentation the top level element is window.  
2. In my auto generated code main.qml is importing QtQuick 1.1 and in your PDF it is importing QtQuick 1.0
3. You have ToolBar element and I have ToolBarLayout element. 
4. You declare element StatusBar and in my code I just see properties showStatusBar: true
    showToolBar: true

	So my question is which code should I use? 
Why so many differences from documentation and real life?
This is really making learning curve steeper.]]></description>
