Closes the form.
procedure Close;
__fastcall Close();
Call Close to close a form.
Attempts to close a form can be aborted by the CloseQuery event dispatcher or the OnCloseQuery event handler.
C++ Examples:
/* This example uses several forms. The first form has its FormStyle property set to MDIForm. The others have their FormStyle properties set to MDIChild and their Visible properties set to true. Add a main menu component and name one of the menu items CloseChildren. This is code for the CloseChildrenClick handler. When the user chooses the CloseChildren command, all the MDI children of Form1 are closed. */ void __fastcall TForm1::CloseChildrenClick(TObject *Sender) { for(int i = MDIChildCount - 1; i >= 0; i--) MDIChildren[i]->Close(); } void __fastcall TForm1::MyArrangeIconsClick(TObject *Sender) { Form1->ArrangeIcons(); } void __fastcall TForm1::MyCascadeClick(TObject *Sender) { Form1->Cascade(); }
