I have two forms called Form1 and Form2. Form2 is called and showed from Form1. Form2 is showed and Form1 lost focus. How to simulate that Form1 is still focused ? I was inspired by the programs which have one main window and several tool windows, all looking focused (with activated title bar color). I dont want to use Form1 as MDI form and Form2 as MDI Child form, because Form2 must have the ability to be moved outside Form1.
