A style permits you to change the appearance of every part and state of a control (buttons, edit boxes, lists, panels, trackbars, checkboxes every official component has a style). VCL controls are made up of parts and states. A VCL style consists of a set of values for each of these parts and states. For instance, a scroll bar has the following parts: frame, slider, and the two side buttons for each direction. The side buttons, for example, have the following states: pressed, disabled, hot, normal.

Styles can be found in “C:\Users\Public\Documents\Embarcadero\Studio\ …<version>…\Styles” folder, please check “C:\Users\Public\Documents\Embarcadero\Studio” for the “Styles” folder. You can also manually get many new (about 40+) Styles by using GetIt Package Manger via Tools->GetIt Package Manager Menu of RAD Studio.

or
Код:

Example below shows how to add selected styles of a project to a combobox items.
C++:
//---------------------------------------------------------------------------
 
#include <vcl.h>
//#include <Vcl.Styles.hpp>
#pragma hdrstop
 
#include "Styles_VCL_Unit1.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner)
{
 ComboBox1->Items->BeginUpdate();
 try
 {
 ComboBox1->Items->Clear();
 DynamicArray<String> styles = Vcl::Themes::TStyleManager::StyleNames;
 
 for(int i = 0; i < styles.Length; ++i)
 {
 ComboBox1->Items->Add(styles[i]);
 }
 }
 __finally
 {
 ComboBox1->Items->EndUpdate();
 }
 
 ComboBox1->Text="";
}
//---------------------------------------------------------------------------
void __fastcall TForm1::ComboBox1Change(TObject *Sender)
{
 Vcl::Themes::TStyleManager::TrySetStyle(ComboBox1->Items->Strings[ComboBox1->ItemIndex],false);
          // Vcl::Themes::TStyleManager::SetStyle("Windows");
}
//---------------------------------------------------------------------------
