Real-Time Marquee Component

Kambiz — Sun, 18 Jan 2009 19:55:49 +0000

The TRealTimeMarquee component is a marquee (both horizontal and vertical) control. This marquee control uses Windows multimedia timer for precise timing to produce a smooth scrolling. Because of that, even when your application is doing time consuming operations, the marquee plays as normal.

The TRealTimeMarquee control is empowered by a simple HTML parsing/rendering class that gives the ability to use HTML for formatting the scrolling text in the most convenience way. By using HTML, you can also define hyper links and insert images in the scrolling text. Whenever the user clicks on a hyper link, an event notifies your application about the clicked link. An event also used for loading HTML images.

The TRealTimeMarquee control supports bi-directional languages. To be more functional, it also supports dir attribute of HTML tags. This enables you to mix content from right-to-left and left-to-right languages in a single line of text.

Background Worker Component

Kambiz — Tue, 18 Nov 2008 20:30:24 +0000

TBackgroundWorker component is the Delphi implementation of .NET BackgroundWorker component.

TBackgroundWorker component allows you to run an operation on a separate, dedicated thread. Time-consuming operations like downloads and database transactions can cause your user interface (UI) to seem as though it has stopped responding while they are running. When you want a responsive UI and you are faced with long delays associated with such operations, TBackgroundWorker component provides a convenient solution.

To execute a time-consuming operation in the background, use TBackgroundWorker component and listen for events that report the progress of your operation and signal when the operation is finished.

Animate Image Component

Kambiz — Tue, 19 Aug 2003 20:30:12 +0000

TAnimateImage is a windowed control similar to TImage for displaying images of an image list on a form. You only need to assign a TImageList component (or its descendant) to its Images property, and set the FrameIndex property to the index of your desired image on the image list.

Of course, TAnimateImage can animate images of an image list too. If you have frames of an animation as Bitmap or Icon, this component offers the easiest way to animate them. For this purpose, TAnimateImage provides some properties to specify interval, segment, and direction of images for the animation.
