Assembling the Flash Paint Application

You have now created all the necessary components for the Flash Paint application. The only remaining step is to create the main routine that puts them all together. To accomplish this, add the following code to the first frame of the main timeline of the flashPaint.fla document:

  // Define an array of the first six tool names. These names match the accepted
  // values within the toolbar button component.
  toolbarBtnNames = ["select", "line", "rectangle", "ellipse", "text", "fill"];

  toolbarBtns = new Array(  );

  // Create a toolbar movie clip to contain all the tools (including 
  // the color selector) and a nested btns movie clip to specifically // contain the toolbar buttons. _root.createEmptyMovieClip("toolbar", _root.getNewDepth( )); toolbar.createEmptyMovieClip("btns", toolbar.getNewDepth( )); var name, btn; // Create a table for holding the buttons. Set the row spacing to three pixels. t = new Table(3); // Loop through all the names of the buttons. for (var i ...
