Hacker’s Guide to Visual FoxPro
An irreverent look at how Visual FoxPro really works. Tells you the inside scoop on every command, function, property, event and method of Visual FoxPro.
FONTMETRIC(), SYSMETRIC()
Everything you ever wanted to know about your fonts and the display subsystem, dredged right out of the heart of the Windows API.
Usage
nResult = FONTMETRIC( nFontAttribute
[, cFontName, nFontSize [, cFontStyle ] ] )
nResult = SYSMETRIC( nScreenAttribute )
|
Parameter |
Value |
Meaning |
|
nFontAttribute |
Numeric, 1 – 20 |
An index to the specific attribute of the font you want returned. See the Help file for the list. |
|
cFontName |
Character |
Name of the font to be examined. |
|
Omitted |
Uses the current font in the active window. |
|
|
nFontSize |
Numeric |
Size in points of the font to be examined. |
|
Omitted |
May only be omitted if cFontName, above, is also omitted. Uses the current font in the active window. |
|
|
cFontStyle |
Character |
Font Style—see the Help file for the entire list. |
|
Omitted |
If all of the optional parameters are omitted, uses the font style of the active window. If a font name and size are specified, uses the Normal style of the specified font. |
|
|
nScreenAttribute |
Numeric, 1 – 32 |
Returns information on the screen's measurements. |
Use these functions to determine the characteristics of fonts and of the display in order to place your output most precisely. These functions are, for all practical purposes, identical to their Windows API counterparts, FONTMETRIC() and GetSystemMetric(). These functions only deal with pixels, rather than the foxel measurement system available through the ScaleMode property.
Example
WAIT WINDOW "Current screen resolution is " + ;
LTRIM(STR(SYSMETRIC(1))) + " by " + ;
LTRIM(STR(SYSMETRIC(2)))
? FONTMETRIC(7,"Times New Roman",10,"B") && 17 pixels
