NAME
+ +
+ + mousescrollsize – compute mouse scroll increment
+ +
+

SYNOPSIS
+ +
+ + #include <draw.h> +
+ + int     mousescrollsize(int maxlines)
+ +
+

DESCRIPTION
+ +
+ + Mousescrollsize computes the number of lines of text that should + be scrolled in response to a mouse scroll wheel click. Maxlines + is the number of lines visible in the text window. +
+ + The default scroll increment is one line. This default can be + overridden by setting the $mousescrollsize environment variable + to an integer, which specifies a constant number of lines, or + to a real number followed by a percent character, indicating that + the scroll increment should be a percentage of the total + number of lines in the window. For example, setting $mousescrollsize + to 50% causes a half-window scroll increment. +
+ + Mousescrollsize is used by 9term(1) and acme(1) to set their scrolling + behavior.

BUGS
+ +
+ + Libdraw expects up and down scroll wheel events to be expressed + as clicks of mouse buttons 4 and 5, but the XFree86 default is + to ignore the scroll wheel. To enable the scroll wheel, change + your InputDevice section of XF86Config−4 to look like:
+ +
+ + Section "InputDevice"
+ +
+ + Identifier       "Mouse0"
+ Driver      "mouse"
+ Option      "Device" "/dev/psaux"
+ # next four lines enable scroll wheel as buttons 4 and 5
+ Option      "Buttons" "5"
+ Option      "Emulate3Buttons" "off"
+ Option      "Protocol" "ImPS/2"
+ Option      "ZAxisMapping" "4 5"
