Question

I am wondering why TFontDialog gives less fonts than Screen.Fonts? (For example, the Arial* font, the Comic font, etc, does not show in TFontDialog)

It also seems that the font list given by TFontDialog is the same as WordPad, whereas the font list given by Screen.Fonts is basically the same as Word.

Thank you very much for your insights!

  if dlgFont1.Execute then

  end;
end;

end.

Screen.Fonts returns all installed fonts, including hidden fonts as administrated in Registry\HKCU\Software\Microsoft\Windows NT\CurrentVersion\Font Management\Inactive Fonts. (Source) Apparently, TFontDialog does not display these hidden fonts.

Furthermore, some fonts listed in Screen.Fonts are not mentioned in the Font combo box of TFontDialog, but are added to the Font style combo box. Take Arial for example: the Font style lists 10 items, which seems to be the combination of the fonts Arial, Arial Black and Arial Narrow.
