G4P Library Not Recognized?

in Contributed Library Questions • 1 year ago

I have just finished installing both the G4P Tool and Library, and both are visible from Processing, though the tool is unable to load. The 'GUI Builder error' states:

Although you can use this tool the sketch created will not work because the G4P library needs to be installed. See G4P at http://www.lagers.org.uk/g4p/

The only G4P library I could find was the one titled: 'guicomponents', which as I said I can insert into a sketch from the drop down options. I have tried this in both 1.5.1 and 2, no luck in either. Is anyone familiar with this issue, or do you possibly know what is wrong?

If it helps, this is the Java error in the compiler:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at javax.swing.ImageIcon.<init>(ImageIcon.java:167) at g4p.tool.gui.GuiDesigner.initComponents(Unknown Source) at g4p.tool.gui.GuiDesigner.<init>(Unknown Source) at g4p.tool.G4PTool.run(Unknown Source) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:642) at java.awt.EventQueue.access$000(EventQueue.java:85) at java.awt.EventQueue$1.run(EventQueue.java:603) at java.awt.EventQueue$1.run(EventQueue.java:601) at java.security.AccessController.doPrivileged(Native Method) at java.security.AccessControlContext$1.doIntersectionPrivilege(AccessControlContext.java:87) at java.awt.EventQueue.dispatchEvent(EventQueue.java:612) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:269) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:184) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:174) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:169) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:161) at java.awt.EventDispatchThread.run(EventDispatchThread.java:122)

I have received and responded to the message you sent before I saw this post.

Although you can use this tool the sketch created will not work because the G4P library needs to be installed. See G4P at http://www.lagers.org.uk/g4p/

This is a warning and as it says the tool will work without the G4P (guicomponents) library but the sketches created will not. This is not the cause of the compiler error.

What I find surprising is that you can import guicomponents from the Processing menus since the tool looks for the library in the same location as Processing ???

Check the location of the library - see this guide

Have you tried using the examples that came with the library to confirm that it has been installed correctly?

Hundreds of people have downloaded this tool and the library and have not experienced this problem so I am not sure what is causing it.

In fact I have just downloaded version V1.1.1 of the tool and it worked fine. Try reinstalling the tool

I believe all that was required was a full system reboot for some reason. The libraries were installed properly, I had tried closing/opening Processing but had no luck. Once I shut it all down, and came back the next day it worked fine. Thanks for your help though.
