This project serves as a solution for depa Assignment 1. This basic color picker has all features listed in the assignment paper.
The project is built on the shoulders of JavaFX which uses MVC for its controls in the back. The custom controls of the app are built the same way:
A control class offers properties one can program against, its skin handles the looks, layout and interaction.
For this color palette, there's four different custom controls:
ch.fhnw.depa.ColorPalette.Control.ColorList- Selection of color with radio buttonsch.fhnw.depa.ColorPalette.Control.ColorRectangle- A canvas that shows the currently selected colorch.fhnw.depa.ColorPalette.Control.ColorSlider- Slider input containing text field, used for one of R, G and B seperatelych.fhnw.depa.ColorPalette.Control.NumberField- A TextField specififcally for numbers
Those controls are wired together and layouted in the class ColorPalettePane.
The ColorPalettePane also adds the top menu bar and the Darken and Brighten
buttons for which no custom control is needed.
The ColorPalettePane also takes over the handling of changes of said controls and updates all
other controls respectively.
The UML has gotten a bit bigger than initially expected, because of the dependencies to JavaFX. Fully qualified class names/paths for parameter and return types have mostly been omitted because of mentioned size issues. Also, the JavaFX classes are added without properties and methods, as the diagram would have exploded in size as well.
The additional XML file is the saved state of draw.io, with which the diagram was created.
