WS_TABSTOP top-level constant Null safety
The window is a control that can receive the keyboard focus when the user presses the TAB key.
Pressing the TAB key changes the keyboard focus to the next control with the WS_TABSTOP style.
You can turn this style on and off to change dialog box navigation. To change this style after a window has been created, use the SetWindowLong function. For user-created windows and modeless dialogs to work with tab stops, alter the message loop to call the IsDialogMessage function.
