About

Requires Java 1.7+

This is a collection of classes I use for my Java projects. Since I haven't reviewed all classes for Java 1.7 this only a part of it.

Classes of Interest

jhv.component.LabelResource

Loads a properties file (used for labels) from a locale path. Looks for it first in JAR and if not found in the same external folder.

jhv.image.ImageResource

Loads a image/icon from a file. Looks for it first in JAR and if not found in the same external folder.

jhv.io.PathCreator

Creates folder structures from an array.

jhv.swing.gridbag.*

Helpers for the GridBagLayout. Contains GridBagPanel and GridBagContraintFactory.

GridBagContraintFactory is for simplify the work with GridBags. It contains several helper functions for creating the most frequently components

Samples:

Direct usage:
// add a checkbox at grid 1,1 with grid width 1
addCheckbox( "label", true, 1, 1, 1 ); 

Relative usage:
// go to beginning of next line
nextLine();
// add a checkbox at the beginnig of the next line with current grid width
addCheckbox( "label", true, CURRENT, CURRENT, CURRENT );
// go to next x grid position
nextX();

jhv.swing.launcher.*

jhv.swing.task.*

Helpers for SwingWorker. The SerialTaskExecutor executes all its Task in serial order (FIFO). The AbstractSerialTask is a abstract wrapper that supplies you with status label and progress bar handling.

jhv.swing.webView.JFXWebView

Simple Web View using JavaFX

jhv.util.config.*

Abstract classes and interfaces for loading/saving application configurations from an properties file.

jhv.util.debug.*

A very simple application logger.

jhv.util.script.*

A simple javax.script API Wrapper. Designed for JavaScript (Mozilla Rhino), but extendable.

See jhv.util.script.SimpleScriptSample.

Sample for using JXJavaScriptMethod:

// prepare arguments
ArrayList<JXScriptArgument<?>> arr = new ArrayList<JXScriptArgument<?>>();
JXScriptArgument arg1 = JXScriptArgument<Integer>("a", 1);
arr.add(arg1);
JXScriptArgument arg2 = JXScriptArgument<Integer>("b", 2);
arr.add(arg2);

//prepare  method with return type integer
JXJavaScriptMethod m = JXJavaScriptMethod(
		new JXScriptFactory(),
		Integer.class
	);

// codesnippet
String snippet = "var c = a + b; return c;";

// invoke script
int val = m.invoke(snippet,arr);

// prints 3
System.out.println(val);

jhv.xml.*
