Qt Designer notes

We use Qt Desinger to design QGIS plugin. Development Tools Install Plugin Builder (for creating Plugin project), Plugin Reloader (to refresh changes to the Plugin while developing) to assist with plugin development. Use Qt Designer to help create Plugin interface. When develope QGIS plugin, your source file folder and QGIS folder might be different. Instead of constantly copying files across, we can use Junction to creat symbolic link. Refer to the Readme.
