/**
|
|
* \class ExamplePlugin
|
|
* \brief Example plugin for QGIS
|
|
*
|
|
* This code is an example plugin for QGIS and a demonstration of the API
|
|
* All QGIS plugins must inherit from the abstract base class QgisPlugin. A
|
|
* plugin must implement the virtual functions defined in QgisPlugin:
|
|
* *name
|
|
* *version
|
|
* *description
|
|
* *type
|
|
*
|
|
* In addition, a plugin must implement a the classFactory and unload
|
|
* functions. Note that these functions must be declared as extern "C"
|
|
*
|
|
* This plugin is not very useful. When loaded, it installs a new menu with two
|
|
* items and illustrates how to connect the items to slots which handle menu events.
|
|
* It also installs a toolbar with one button. When clicked, the button zooms the
|
|
* map to the previous extent.
|
|
*
|
|
* After the UI elements are initialized the plugin zooms the map canvas to the
|
|
* full extent of all layers.
