CallBack 2

This stack demonstrates the new callbacks added in HyperStudio 4.0. It's just a quick test stack I used during development of HyperLogo to make sure all the features were in, and that I wasn't breaking things as I added new features. You'll see actual (and hopefully working!) demonstrations of all of the new callbacks, though.

Tested with HyperStudio 4.0 Mac and HyperStudio 4.0 Windows. This stack will not work on earlier versions.

Color Picker

This stack shows a simple color picker. Draggable graphic controls select the levels of red, green and blue color, which are also shown as HyperLogo numeric color values in text boxes next to the draggable graphic slider controls.

The main script is in a hidden button at the top right of the card. See the scripts on the draggable graphic slider controls to see how the actions are triggered.

Tested with HyperStudio 3.3 Mac. This stack should work with HyperStudio 3.x and better on either platform.

ON Samples

HyperLogo in HyperStudio 4.0 has a powerful new feature called ON events that let you intercept the event handling in HyperStudio. This stack shows just a few of the cool things you can do with ON event handlers. It includes:

• Rollover buttons, including animated buttons and buttons that perform specific actions.
• Text boxes that respond to specific keys in special ways. Think about running a script when you press RETURN in a text item!
• Key processing. The demo is a calculator keypad that lights the buttons as you type number keys.
• Mouse processing. You'll see a simple but effective paint program implemented in HyperLogo, and a graphic that follows the cursor in a limited area of the screen.
• Scrolling text. HyperLogo can control text scrolling in very specific ways. The demo shows a text item that scrolls faster or slower in resonse to clicks on buttons or the position of the cursor on the text item.

Tested with HyperStudio 4.0 Mac and HyperStudio 4.0 Windows. This stack will not work on earlier versions.
