What i am trying to accomplish is to create new touchkeyboard.

First i created buttons which i derive from speed buttons.
That done, now i need to create multiple buttons and layout them somewhere. This is were i get stuck.

I created a new component which i derive from TGraphicControl (this should be my new touchkeyboard), but i don’t know how to add components to canvas. I actually don’t know whether i’m supposed to add them to canvas or to some other component (eg. panel)!?!

Is my approach OK?

Thanks in advance.

    Because of your wording and confusion between Panel, Canvas and custom controls in general, I assume you’re a Delphi beginner. You need to learn about frames: embarcadero docwiki link on frames

    Frames allow you to create re-usable portions of GUI. You use the IDE to “draw” the frame, you can then place that composite control (the frame) onto forms or other frames. It’s a very powerful feature and it’s conceptually very close to what other languages call “custom controls” (very close to what asp.net or WPF consider a custom control to be).

    In the Delphi world, when you say “custom control”, people would normally expect you to want to create an reusable control that’s placed in a package and it’s installed in the IDE. It’s an fairly advanced subject. If that’s what you want then I misunderstood the question, sorry.
