I am a new developer in delphi, use Delphi XE6. I want to know the attribute about one component quickly, the problem is where can i find related api about component in tool palette? Thanks!
If I'm understanding your question correctly, I think the best way to get a sense of a component is to add it to your form, then select it, and check out its attributes in the Object Inspector.
An alternative is to reference the class in question (say, TButton) in your code, and place the cursor somewhere in the class name, and invoke the Help (press F1) to read up on the class and its members.
