Description of DesignerFont :
With Delphi 2 to 5 there is no 'official' way to select the Font, used by the FormDesigner to generate new objects on a form. So you have to use the old fashiond MS Sans Serif in 8 point, and change manually the font after all. Delphi DesignerFont (DDF) configueres the IDE to use a special font, size and effects for generating the objects on a form. DDF has a comfortable 8-) user interface, so you can easy set the IDE to use the font you prefer.
