- Goto spec source

# Description

    package Gtk.Extra.Plot_Canvas is

A Gtk_Plot_Canvas is a special kind of drawing area used with Gtk_Plot widgets.

It provides drag-and-drop capabilities for the texts, legends, points... available in a Gtk_Plot.

Note that this widget is specifically designed for Gtk_Plot widgets, and won't provide any other capability for other kinds of widgets.

Like any child of Gtk_Layout, this widget can have an almost unlimited size for its children, and provides scrolling.

Binding from C File version gtkextra 2.1.1
