Gtk2::Ex::Geo Description

The main module to use for geospatial applications Gtk2::Ex::Geo is the main Perl module to use for geospatial applications.Gtk2::Ex::Geo is a namespace for modules, classes, and widgets for geospatial applications. This package contains the modules:Gtk2::Ex::GeoThe main module to 'use'. Contains also function 'simple', which constructs a simple geospatial desktop application.Gtk2::Ex::Geo::CanvasA subclass of Gtk2::Gdk::Pixbuf. Constructs a pixbuf from a stack of geospatial layer objects by calling the 'render' method for each $layer. Embedded in Gtk2::Ex::Geo::Overlay.Gtk2::Ex::Geo::OverlayA subclass of Gtk2::ScrolledWindow. A canvas in a scrolled window. Contains a list of layer objects. Functionality includes redraw, support for selections (point, line, path, rectangle, polygon, or many of them), zoom, pan, and conversion between event and world (layer) coordinates.Gtk2::Ex::Geo::LayerThe root class for geospatial layers. A geospatial layer is a typically a subclass of a geospatial data (raster, vector features, or something else) and of this class. The idea is that this class contains visualization information (transparency, palette, colors, symbology, label placement, etc) for the data. Contains many callbacks that are fired as a result of user using context menu, making a selection, etc. Uses layer dialogs.Gtk2::Ex::Geo::DialogMasterA class which maintains a set of Glade dialogs taken from XML in DATA section.Gtk2::Ex::Geo::DialogsA subclass of Gtk2::Ex::Geo::DialogMaster. Contains dialogs for Gtk2::Ex::Geo::Layer.Gtk2::Ex::Geo::GlueTypically a singleton class for an object, which manages a Gtk2::Ex::Geo::Overlay widget, a Gtk2::TreeView widgets, and other widgets of a geospatial application. The object also takes care of popping up context menus and other things.Gtk2::Ex::Geo::HistoryEmbedded in Gtk2::Ex::Geo::Glue. Input history a'la (at least attempting) GNU history that is used by Glue object with Gtk2::Entry.Gtk2::Ex::Geo::TreeDumperFrom http://www.asofyet.org/muppet/software/gtk2-perl/treedumper.pl-txt For inspecting layer and other objects.
