I admit a little explenation would help since it is not so trivial.
Thanks for the explanation - definitely not a "general knowledge" thing.
Searching in Google I found no mention of this in any other GUI toolkits
or IDE's - so I gather this is a Delphi VCL specific thing?
Yes.
Does the rest of LCL's TFont work the same, or is this negative size
font only implemented in TSynEdit?
It should. Any diference on whatever widgetset is a bug.
A positive fontsize is the size of a font in points
A negative fontsize is the size of a font in points including the
internal leading at the top of the line
So in GTK1, GTK2, Qt and the myriad of other GUI toolkits with font
dialogs. When the user selects 12pt font, which one is it. Option 1 or 2
above?
Should be 1 since positive.
So where exactly or why would you use the negative font size? Like I
said, I have never seen this anywhere else but in Lazarus IDE.
I usually see them when setting heights (in pixels). Agreed, imo, they
shouldn't be shown in lazaris as negative.
