Description

Handy Scrolling Sample Illustrates a number of techniques that can be used for providing convenient and easy to use scrolling facilities in your application's windows. Scrolling techniques illustrated include: - implementing live scrolling scroll bars, - drawing proportional scroll bars, - using the hand cursor for scrolling allowing users to 'virtually' grab a window's contents and drag it around with the mouse. - scrolling using the keyboard. Other interesting techniques illustrated include: - Setting the cursor and handling mouse moved events for various regions of the screen, - Optimizing drawing performance by limiting drawing operations to those ones that will have a visual effect on the screen (This can dramatically improve the speed of drawing during scrolling operations). It's just plain handy!!! Requirements: CarbonLib Keywords: Scrolling, Scroll, Scrollbars, Handy, Handyman, proportional, hand, mouse moved.
