For this homework you will be constructing a simple ShapeDrawer GUI that loads a series of shape drawing instructions from a text file that are then transformed and added to a virtual canvas in JavaFX.
The GUI needs to consist of two major components: (1) A control/options menu a small series of JavaFX controls and labels that lets a user load a text file from which shapes will be drawn during event handling. Appropriate components should* include the following: i. a clear button that clears all shapes currently drawn on the the canvas (the logic of this should be extremely simple.) ii. a filePath textfield that lets users input a file path from which drawing instructions will loaded. iii. a load button that processes the currently entered text from the element ii by loading it as a file object, then reading elements line-by-line (likely with a Scanner object) and drawing appropriate shapes on the canvas (see below.) (2) The drawing canvas this should* be a simple group to which elements are added as a result of the load button being pressed, or cleared as a result of the clear button being pressed. Note that it should be translated (likely via setTranslationY) to appear below the menu elements from (1).
Each shape is drawn using a single line of within a text file (see example sampleshapes.txt attached with assignment.) You can assume only valid lines are provided in any input file. Each line consists of four tokens: i. The first string token should correspond to one of three shapes: Line, Ellipse, or Rectangle. Your code should be case insensitive to these (i.e. ELLIPSE is treated the same as Ellipse). ii-v. The next four int tokens are parameters to the appropriate JavaFX shape constructor (e.g. for Rectangle these represent startX, startY, width, and height). vi-viii. The last three int tokens correspond to RGB values (0-255) used for either the shapes stroke (for the Line) or fill (for the Rectangle and Ellipse).
