Copies a component to the clipboard.
procedure SetComponent(Component: TComponent);
__fastcall SetComponent(TComponent * Component);
Use SetComponent to copy a component to the clipboard.
C++ Examples:
/* This example uses a button and a group box on a form. When the user clicks the button, the button is copied to the Clipboard and then retrieved from the Clipboard and placed in the new parent of the button, the group box. The name of the original button is changed to avoid having two components with the same name at the same time. */ __fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner) { // Register the TButton class so that the clipboard can // read and write button objects TMetaClass *MetaClass = __classid(TButton); RegisterClasses(&MetaClass, 0); } #include <Clipbrd.hpp> void __fastcall TForm1::Button1Click(TObject *Sender) { TButton *groupButton; // copy the button to the clipboard Clipboard()->SetComponent(Button1); // rename the button which is still on the form Button1->Name = "OriginalButton"; // Now retrieve the button from the clipboard // and add it to GroupBox1 // Note that the clipboard button is named Button1, // while the source button has been renamed // to "OriginalButton" groupButton = (TButton *)Clipboard()->GetComponent(this, GroupBox1); groupButton->Top = Button1->Top + 30; }
