Getting Started with TAdvSmoothCalendar in Delphi Delphi’s standard calendar components can feel visually dated for modern user interfaces. The TAdvSmoothCalendar component, part of the TMS Smooth Controls pack, offers a highly customizable, fluid, and visually appealing alternative. It features smooth animations, sophisticated styling, and advanced date management capabilities.
Here is a practical guide to implementing and mastering TAdvSmoothCalendar in your Delphi applications. Key Features
Anti-aliased Drawing: Renders sharp, modern visual elements at any scale.
Complex Date Marking: Supports multi-select dates, hints, and custom status styling per day.
Fluid Animations: Provides smooth transitions when switching months, years, or decades.
Complete Styling Control: Offers extensive gradient, font, and background configuration options. Installation and Setup
Before using the component, ensure you have the TMS Smooth Controls Pack or TMS VCL Subscription installed. Open your Delphi IDE. Create a new Windows VCL Application. Locate the TMS Smooth category in the Component Palette. Drag and drop TAdvSmoothCalendar onto your main form. Core Properties to Configure
To customize the look and behavior of your calendar, focus on these essential properties in the Object Inspector: Date: Sets or retrieves the currently selected TDateTime.
MultiSelect: Set to True to allow users to select a range of dates.
MonthAppearance / YearAppearance: Controls the fonts, colors, and gradients for specific views.
Header: Configures the visibility, font, and alignment of the top month/year navigation bar.
Footer: Configures the bottom bar, often used to display the current date or custom text. Practical Code Examples 1. Handling Date Selection
To capture when a user clicks or changes a date, use the OnChange event.
procedure TForm1.AdvSmoothCalendar1Change(Sender: TObject; Date: TDateTime); begin // Display the selected date in the form’s title bar Self.Caption := ‘Selected Date: ’ + DateToStr(Date); end; Use code with caution. 2. Highlighting Specific Dates (Status Items)
You can visually mark holidays, deadlines, or events by adding items to the StatusItems collection. Use code with caution. 3. Enabling Multi-Date Range Selection
To let users select a start and end date, configure the selection properties in code.
procedure TForm1.SetupRangeSelection; begin AdvSmoothCalendar1.MultiSelect := True; // Set an initial programmatic range AdvSmoothCalendar1.SelectedDateRangeStart := EncodeDate(2026, 6, 01); AdvSmoothCalendar1.SelectedDateRangeEnd := EncodeDate(2026, 6, 07); end; procedure TForm1.GetSelectedRange; begin // Retrieve the user’s selection if AdvSmoothCalendar1.MultiSelect then begin ShowMessage(Format(‘Selected from %s to %s’, [DateToStr(AdvSmoothCalendar1.SelectedDateRangeStart), DateToStr(AdvSmoothCalendar1.SelectedDateRangeEnd)])); end; end; Use code with caution. Styling and Themes
TAdvSmoothCalendar relies on the TMSfill property structures, allowing for complex gradient backgrounds. Instead of configuring every color manually, you can use the built-in global styles.
Right-click the component on your form at design time to access the context menu. From there, you can instantly apply pre-made styles like Office 2010 Blue, Office 2013 White, or Metro Dark to match your application’s overall theme. Conclusion
The TAdvSmoothCalendar bridges the gap between functional date picking and modern UI design in Delphi. By mastering its selection events, status items, and appearance properties, you can build intuitive, presentation-ready scheduling interfaces.
