Title: How to display status messages.
Question: When my form was minimized to icon, I wanted to change the message viewed when switching between applications in the Task Manager. That's a very good work...
Answer:
First, you need to define the default messages:
Const
DefMsgNorm = 'MyApp version 1.0';
DefMsgIcon = 'MyApp. (Use F12 to turn of)';
And two global variables:
Var
ActMsgNorm : String;
ActMsgIcon : String;
When opening the main form, you should inizialize the variables to the constants.
Procedure TFormMain.FormCreate( Sender : TObject );
Begin
ActMsgNorm := DefMsgNorm;
ActMsgIcon := DefMsgIcon;
Application.Title := ActMsgNorm;
End;
Then, you only must add this in the OnResize event:
Procedure TFormMain.FormResize( Sender : TObject );
Begin
If ( FormMain.WindowState = wsMinimized ) Then
Application.Title := ActMsgIcon
Else
Application.Title := ActMsgNorm;
End;
That's very portable, because if you need to change the messages at runtime, you just must change the value to the two variables and the system need no change.
