fx-yearmonth-picker

A year-month date picker component for java fx. Requires java 11 and javafx 11 or higher (tested with jdk 11 and jfx 17.02)

There are two versions:

1. YearMonthPickerCombo - a combobox that return a YearMonth.
2. YearMonthPicker - A custom control that resembles DatePicker where the user can click a calendar and then pick the desired year month.

See test.alipsa.ymp.YearMonthPickerExample for a simple example of both. Here's an example screenshot:

Both works similar to a combo box i.e. you do getValue() to get the value and setOnAction() to capture a value change e.g.

YearMonthPicker ymp = new YearMonthPicker();
ymp.setOnAction(a -> System.out.println("Default YearMonthPicker, Value picked was " + ymp.getValue()));

There are no external dependencies, and the jar file is about 40kb so nice and small. You can download the jar file from the release section or add the following to your maven file:

<dependency>
  <groupId>se.alipsa</groupId>
  <artifactId>fx-yearmonth-picker</artifactId>
  <version>1.1.0</version>
</dependency>

...or the equivalent to you favorite build tool.

Note that the dependency on java fx is set to "provided" meaning that you need to add a dependency to javafx explicitly in your project or use a jvm where javafx is bundled (such as Bellsofts liberica full)

The module name for this library is se.alipsa.ymp
