In this article, we will show you how to use GANTT Control VCL in your Delphi 10.3 Rio projects. We will cover the following topics:

How to add a Gantt chart to your form

How to customize the appearance and behavior of the Gantt chart

How to load and save data from different sources

How to use additional features such as Pert chart, print preview, calendar, critical path and more

How to Install GANTT Control VCL

GANTT Control VCL is compatible with Delphi 10.3 Rio and supports both 32-bit and 64-bit Windows-VCL applications. You can download the trial version of the component from or use Embarcadero's GetIt package manager to install it.

After downloading the component, run the setup file and follow the instructions on the screen. You will need to select the target platforms and IDE versions that you want to install the component for.

Once the installation is complete, you will find the GANTT Control component on the Component Palette under the Weise Software category.

How to Add a Gantt Chart to Your Form

To add a Gantt chart to your form, simply drag and drop the TGanttControl component from the Component Palette onto your form. You can also use the Object Inspector to change its properties and events.

The TGanttControl component consists of three main parts: a tree view on the left, a Gantt chart view on the right, and a time scale on the top. The tree view displays the hierarchical structure of the tasks and allows you to expand and collapse them. The Gantt chart view shows the graphical representation of the tasks along the time axis and allows you to edit them using drag-and-drop or mouse actions. The time scale shows the units of time (such as days, weeks, months, etc.) and allows you to zoom in and out.

By default, the TGanttControl component has some sample data loaded for demonstration purposes. You can clear this data by calling the Clear method or by setting the Tasks property to nil.

How to Customize the Appearance and Behavior of the Gantt Chart

GANTT Control VCL offers many options to customize the appearance and behavior of the Gantt chart according to your needs and preferences. You can use the Object Inspector or code to change these options.

Some of the most common options are:

The Columns property allows you to add, remove or modify the columns in the tree view.

The Bars property allows you to define different types of bars for different types of tasks (such as normal, milestone, summary, etc.). You can also specify their colors, shapes, patterns, captions, etc.

The Links property allows you to define different types of links between tasks (such as finish-to-start, start-to-start, etc.). You can also specify their colors, styles, arrows, etc.

The TimeScale property allows you to customize the time scale units, formats, intervals, etc.

The Options property allows you to enable or disable various features such as grid lines, selection, editing, scrolling, zooming, tooltips, etc.

The Styles property allows you to apply predefined or custom styles to various elements of the Gantt chart such as background, header, footer, legend, etc.
