ShowMessage procedure

Declaration

procedure ShowMessage(const aMsg: string)

Arguments

Description

The simplest message dialog: takes a simple string as argument, displays it in a box, and waits for a mouse-click or enter-key event before returning to the calling routine or program.

This is a modal procedure call; the box is displayed, receives focus, and does not relinquish focus until the OK box is clicked or otherwise selected.
