public int get_approximate_char_width ()
Gets the approximate character width for a font metrics structure. This is merely a representative value
useful, for example, for determining the initial size for a window. Actual characters in text will be wider and narrower than this.
-
public int get_approximate_digit_width ()
Gets the approximate digit width for a font metrics structure. This is merely a representative value
useful, for example, for determining the initial size for a window. Actual digits in text can be wider or narrower than this, though
this value is generally somewhat more accurate than the result of
get_approximate_char_width for digits.
-
public int get_ascent ()
Gets the ascent from a font metrics structure. The ascent is the distance from the baseline to the
logical top of a line of text. (The logical top may be above or below the top of the actual drawn ink. It is necessary to lay out the
text to figure where the ink will be.)
-
public int get_descent ()
Gets the descent from a font metrics structure. The descent is the distance from the baseline to the
logical bottom of a line of text. (The logical bottom may be above or below the bottom of the actual drawn ink. It is necessary to lay
out the text to figure where the ink will be.)
-
public int get_strikethrough_position ()
Gets the suggested position to draw the strikethrough. The value returned is the distance above
the baseline of the top of the strikethrough.
-
public int get_strikethrough_thickness ()
Gets the suggested thickness to draw for the strikethrough.
-
public int get_underline_position ()
Gets the suggested position to draw the underline. The value returned is the distance above
the baseline of the top of the underline. Since most fonts have underline positions beneath the baseline, this value is typically
negative.
-
public int get_underline_thickness ()
Gets the suggested thickness to draw for the underline.
