I want to know how can I write a module to show something like clock or other thing on Borland Delphi 7 IDE status bar, because I know it's possible but I couldn't find how!
To insert a text in a StatusBar, you have to insert a panel first. Just select your statusbar, find the property "Panels" (or perform double click over the statusbar) and click in "Add new". After that, you can write what you want inside the panel in the property "Text" (you can insert one or more panels). To do it programmatically, you can do something like this:
procedure TForm1.Timer1Timer(Sender: TObject);
begin
StatusBar1.Panels[0].Text := 'Today is: ' + FormatDateTime('dd/mm/yyyy hh:nn:ss', Now);
end;
