Questions about "fonts" in QM

[ssimop]

Dear Gintaras,

Let me start saying that I am sorry if I am asking things that either I should have known and/or I could have found in help topics or in the forum. I would like that you clarify some issues regarding fonts unless there exists a tutorial I could read :

1. What is the difference between statements :

fTask.SetFont(id(4 hDlg))
g.SetDialogFont(hDlg "11")

where

CFont+ fTask
and
__Font-

2. What is exactly variable _hfont and how it may be used. For example if the font is changed in a dialog field, I wonder whether statement

SendMessageW (id(10 hDlg)) WM_SETFONT _hfont 0

is the only way to restore _hfont ?

3. Is there a way to create a new font, starting with _hfont but with bold characters?

Many thanks in advance - Best regards.

1. CFont - I don't remember what it is, I guess something from forum. __Font is in System. It sends WM_SETFONT message to all specified controls; I guess CFont too.

2. _hfont now is undocumented. It is used in System functions. It is default dialog font handle. Another way to restore changed font - send WM_GETFONT before changing, save the handle in a thread variable, then send WM_SETFONT to restore.

3. __Font.Create has parameter templateFont. It can be a font or a special value, eg 1 is dialog font.

,if(t_oldFont) SendDlgItemMessage(hDlg 4 WM_SETFONT t_oldFont 1); t_oldFont=0
ret 1

To get a copy of _hfont:
__Font- t_f.Create("" 0 0 0 1)

Thank you very much, indeed! It is now clear to me.
