TdxRibbonForm Class
A Ribbon form class.
Declaration
TdxRibbonForm = class(
TdxCustomRibbonForm
)Remarks
The TdxRibbonForm class implements Ribbon form functionality with support for Fluent Design effects on Microsoft Windows® 10 and newer operating systems. A Ribbon form can integrate a TdxRibbon control with its title bar as the main application UI and display additional title bar buttons.
Fluent Design Application Template
The DevExpress VCL 23.2 Ribbon Based Application template creates a new application project with a form derived from the TdxRibbonForm class. The new form has a preconfigured TdxSkinController component and an embedded TdxRibbon control with one tab.
To create a new Fluent Design application, click File | New → Other… in the main menu of your RAD Studio IDE. Then, select the DevExpress VCL 23.2 Fluent Design Application template.
Select a Ribbon style.
