Re: Graph model zoom

[guilhelm savin <guilhelm.savin AT gmail.com>]

Since 1.3, Viewer does not depend on a specific GUI like Swing. It is modeled in a generic way so we can have different types of GUI.

However, the default viewer (the one used on a display() call) uses Swing. The best way, for your problem, is not to use the display() method, but to build the Viewer, so you can ask it to not create a JFrame. Then you can add a View, which will be a JPanel, and add it on your own frame.

See "Integrating the viewer in your gui" here : https://graphstream.github.io/doc/Tutorials/Graph-Visualisation/#integrating-the-viewer-in-your-gui

Cheers.

First, I have to say that I'm beginner on java so it's quite difficult to understand events. 

Till you wrote me, I have read documentation and examples about zoom. I have found the code which change scale. So I wrote MouseWheelActionListener to do scale action. Also found arrow keys actions and shift+R keys combination. So for my demo project is enough functionalities on zoom. But now I have other problem. When I call function display, then program start show JFrame window and create graph. But where Jframe object is created? What is his name. Because I would like to add more components to this frame. I can't understand hierarchy between View of graph and Jframe.

 

This is my learning code. It generates to windows because i tried to put graph view to panel which is my create Jframe. Alse where are mouse actions written.

Hi,

Maybe a good starting point could bould be to watch the default keys listener here : https://github.com/graphstream/gs-core/blob/master/src/org/graphstream/ui/view/util/DefaultShortcutManager.java

There is some code about zooming in and out the graph, and set the center of the graph.

Hope it helps...

Hi! I would know how to write action event which zooms the graph at the mouse
position, because when I generate big data model, the spots of vertex is very
small to watch be connections.
