+
+Answer: gcc loves to spit out long compiler errors for template. the problem is that oapplication factory
+wants to call a static method called appName() on your widget. You need to add static QString appName()
+and return the name of the executable

+Hi newbie,
+this directory contains a set of examples for various
+API you may want to use. The examples go from simple
+to harder and must be understand as an extension
+of the examples from Qt in your source package.
+Be sure to look there at first and at their excelent 
+tutorials as well.
+
+Note: that some files are found in apps/Examples to really
+show how to include apps properly.
+
+Note: to integrate your apps into the build 
+    make clean-configs
+    put your application into a sourcedir
+    edit $OPIEDIR/packages
+    make 
+
+
+
+        simple/                 -  Simple Widget with quit button
+        simple-icon     -  Simple Widget with loading resources and playing simple sound
+        simple-main     -  Simple QMainWindow usage with toolbar and actions
+        main-tab        -  QMainWindow with central tab widget
+        simple-pim      -  QMainWindow + QListView + PIM
+        big-pim                 -  Usage of Opie PIM with BigScreen Extension
+
