Here’s how to hide / show the mouse cursor inside of flash.
// Hide the mouse cursor
stage.canvas.style.cursor = “none”;
//Show the mouse cursor
stage.canvas.style.cursor = “default”;
If you need to manage the visibility or control an object that exists on the timeline of the flash canvas document you need to do the following.
// create a variable and assign it to the stage – on the root timeline
var mainStage = this;
// name an instance on the root timeline of the document – in this case a movieclip named button //with an instance name of “myButton”
// then assign properties to it with the following language
mainStage.myButton.visible = “false”;
// This will hide your button
