procedure ShowMessage(const AMessage: string);
Applications or the operating system itself use message windows to warn or inform the user. The title of the window is the project name. There is no option to click other than the OK button.
ShowMessage Behaves Differently On Different Platforms On desktop platforms, ShowMessage behaves synchronously. The call finishes only when the user closes the dialog box. On mobile platforms, ShowMessage behaves asynchronously. The call finishes instantaneously, it does not wait for the user to close the dialog box.
NOTE: Insert carriage return and line feed characters (#13#10) into the string to generate multi line message display.
Example
var
word : String;
{
word = 'Hello World';
// Show a simple message
ShowMessage(word);
// Show a blank message
ShowMessage('');
// Split this into two lines
ShowMessage('Hello '+#13#10+'World');
}
Output:
Output1: Hello World
Output2:
Output3: Hello
- World
