 Posted: Tue May 01, 2007 10:30 pm Post subject: How to get current LOGFONT |
 |
|
Hi,
1) How can I get current LOGFONT?
I want to inquire the current font without displaying any dialog and without
asking to select the font.
2) If I want to rotate the text can I set only sub set of LOGFONT
parameters. For example:
....
log_font.lfHeight = font_height;
log_font.lfWeight = FW_SEMIBOLD;
log_font.lfEscapement = (LONG_T)(angle*10);
....
hfnt = CreateFontIndirect(&log_font);
Do I need to worry about the rest of parameters or I can just call:
memset(&log_font, 0, sizeof(LOGFONT));
Thank you.
Rony. |

Use GetObject() on an HFONT handle. Check the documentation for this. To
get the current font HFONT, if you've never actually selected one,
you'll probably find that GetStockObject() with a suitable parameter
does the job. Or perhaps the WM_GETFONT message will work.

Surely.

If you do, you'll get defaults for all the other values. This may or may
not be what you want.
BTW, it's often considered good practice to avoid memset() when it's not
necessary. In this case
LOGFONT log_font = { 0 };
log_font.lfHeight = font_height;
log_font.lfWeight = FW_SEMIBOLD;
log_font.lfEscapement = (LONG_T)(angle*10);
would do fine. On the other hand, given you've been asking about getting
the current font details, then something like (untested)
LOGFONT log_font = { 0 };
HFONT Font = reinterpret_cast<::SendMessage(hWnd, WM_GETFONT, 0, 0));
GetObject(HFont, sizeof log_font, &log_font);
log_font.lfEscapement = (LONG_T)(angle*10);
looks like the right way to go.
