How can I make my form resize more smoothly?

Question

When resizing a form with many controls, the form looks bad because of flickering. What are some tips to have a smoother form resizing?

Answer 1

I avoid flicker by aligning no more than 1 non-alClient component per parent, always paired with a alClient (e.g. a TPanel) to contain all other components. Group them in panels without borders.

Say you want to allign three things: alLeft, alTop and alClient for the main view. Dont do this: Form alTop alLeft alClient // your main view

But instead embed these as follows: Form alTop alClient // panel to avoid flicker alLeft alClient // your main view

Same story for embedding several alTop elements.
