TOPIC:

As I understand it, I've encountered an issue with the OnResize method. I've attached the attachment.
In my opinion, OnResize should be called continuously while the form is being resized, but it's only called twice: at the beginning and end of the resize.
Is this normal behavior or a bug?

I use CT 8.9

Sir
it's normal behavior
of an event

How can I interactively track resizing of a form or component? OnPaint is called for every pixel resizing, so why does OnResize work differently?

My suggestion is to replace 
Form.WindowProc with your procedure

For sample Look at:

codetyphon\typhon\ide\ct_emb_formeditor.pas

//======
TEmbedMessageHandler

procedure TEmbedMessageHandler.HookControl(AControl: TControl);
procedure TEmbedMessageHandler.UnHookControl;
