creating a firemonkey component

Question

I\'m working with Firemonkey in Delphi XE4 and I\'m unable to create a new component using the menu item Component -> New Component. Whether the component is a VCL or Firemonkey

Answer 1

Creating components is fairly straightforward in code.

• Create a unit.
• Add code for your component.

• Add a Register procedure.

  procedure Register;
  begin
    RegisterComponents('NewPage', [TMyComponent]);
  end;
  

• Add a declaration for Register in the implements section.

• Add a call to RegisterFMXClasses in your initialization section.

  implementation
  uses FMX.Types;
  ...
  initialization
    RegisterFMXClasses([TMyComponent]);
  end.
  

• Create a package.

• Add the unit to the package.
• Right-click the package (in the top-right panel) and select Install.

(Note: It's usually best to create your component at run time whilst testing. You only need to do the package stuff once it's fairly stable).
