Display and edit JGraphT graphs on android

Installation

As dependency

1. Save AAR as ${project}/app/libs/andrograph.aar
2. project/build.gradle (excerpt):

allprojects {
	repositories {
		//your repos here
		flatDir{
            dirs 'libs'
        }
    }
}

3. project/app/build.gradle (excerpt):

dependencies {
	//your dependencies here
	compile 'org.jgrapht:jgrapht-core:0.9.2'
    compile(name:'andrograph', ext:'aar')
}

As module

1. Head to "Releases" and grab latest AAR
2. Add to Android Studio as "New Module -> Import .JAR/.AAR"
3. Edit your apps build.gradle to add compile project(':andrograph-release') as dependency

Usage

• Have a JGraphT graph
• Add a GraphView to an Activity
• Build a GraphViewController
• Attach GraphViewController to GraphView
• Enjoy editing

Select edges

DefaultGraphViewController can be equipped with an EdgeEvent instance. This will be called before edges are updated, i.e. before adding and removing edges. By consuming the event (return true), no further actions will be done. By not consuming the event (return false), the default action will be performed.

This can be used e.g. to catch selection of edges, store it somehow, and paint it differently (via reference to an EdgePaintProvider)

andrograph's Issues

Enable custom drawing of vertices and edges

Maybe refactor drawVertex/drawEdge out to a dedcated interface?

Delete vertices

Find a nice way to delete vertices from graphs
