From an old Otto's Idea
I created this class because every year at school we have graduation day and on the screen in the auditorium I had to display all the sponsors who help us organize the event every year. With this class I can do it easily without resorting to existing applications on the market.
The TScrollImg class is a custom control for FiveWin/Harbour that allows you to create a scrollable image gallery (banner) inside a Windows application. Images can be associated with URLs, allowing users to open websites with a click. The control is designed to be fluid, without flickering, and supports flexible configurations to adapt to different needs.
Main Features
Configure the aBanners Array
The aBanners array defines the images to display. It can be in 3 formats:
Simple (images only):
LOCAL aBanners := {"Bosch.png", "Brother.png", "Canon.png"}
In this case, the images scroll but are not clickable (no URL associated).
With URLs (images and links):
LOCAL aBanners := {{"Bosch.png", "www.bosch.it"}, {"Brother.png", "www.brother.it"}}
The images are clickable, and a click opens the URL in the browser.
With codeblock (images and codeblock):
local aBanners := { ;
{ "Bosch.png", "www.bosch.it", .F. },;
{ "Brother.png", "www.brother.it", .F. },;
{ "Canon.png", {|| MsgInfo("select one category") }, .T. }}
The images are clickable, and a click eval the codeblock . w
We could then create a scroll of images of the categories and open an xbrowse with the products of that category
User Interaction
Scrolling: The images scroll automatically based on nMode and nSpeed.
Cursor: When the mouse hovers over an image with a URL, the cursor changes to a hand, indicating that it is clickable.
Click: Clicking an image with a URL opens the associated website in the default browser. or run a codeblock
the animation starts automatically but by means of a button you can change the direction, the speed, the space between the images
Usage

The control is designed to be fluid, without flickering, and supports flexible configurations to adapt to different needs.
Main Features
- Image scrolling: Images scroll horizontally (left or right) with a configurable speed.
URL association: Each image can have an associated URL, which opens in the default browser with a click.
Visual feedback: The cursor becomes a hand when it passes over an image with a valid URL.
Customization: Supports background colors, borders, sizes and scroll modes.
Backwards compatibility: Works with simple image arrays (without URLs) or with associated URLs.
Optimization: Use double buffering to eliminate flickering during animation
