.TH GRIDMENU 1 grid-0.0 |
||||
.SH NAME |
||||
gridmenu \- grid window manager menu |
||||
.SH SYNOPSIS |
||||
.B gridmenu |
||||
.RB [ \-v ] |
||||
.RB [ \-t |
||||
.IR title ] |
||||
.SH DESCRIPTION |
||||
.SS Overview |
||||
.B gridmenu |
||||
is a generic, highly customizable, and efficient menu for the X Window System, |
||||
originally designed for |
||||
.BR grid (1). |
||||
It supports arbitrary, user defined menu contents. |
||||
.SS Options |
||||
.TP |
||||
.B \-v |
||||
prints version information to stdout, then exits. |
||||
.TP |
||||
.BI \-t " title" |
||||
displays |
||||
.I title |
||||
above the menu. |
||||
.SS Usage |
||||
.B gridmenu |
||||
reads a list of newline-separated items from stdin and creates a menu. |
||||
When the user selects an item or enters any text and presses Enter, his choice |
||||
is printed to stdout and |
||||
.B gridmenu |
||||
terminates. |
||||
.SS Keyboard Control |
||||
.B gridmenu |
||||
is completely controlled by the keyboard. The following keys are recognized: |
||||
.TP 2 |
||||
Any printable character |
||||
appends the character to the text in the input field. This works as a filter: |
||||
only items containing this text will be displayed. |
||||
.TP 2 |
||||
Left/Right (Control-p/Control-n) |
||||
select the previous/next item. |
||||
.TP 2 |
||||
Tab (Control-i) |
||||
copy the selected item to the input field. |
||||
.TP 2 |
||||
Enter (Control-j) |
||||
confirm selection and quit (print the selected item to stdout). |
||||
.TP 2 |
||||
Shift-Enter (Shift-Control-j) |
||||
confirm selection and quit (print the text in the input field to stdout). |
||||
.TP 2 |
||||
Escape (Control-[) |
||||
quit without selecting an item. |
||||
.TP 2 |
||||
Backspace (Control-h) |
||||
remove enough characters from the input field to change its filtering effect. |
||||
.TP 2 |
||||
Control-u |
||||
remove all characters from the input field. |
||||
.SS Exit codes |
||||
.B gridmenu |
||||
returns |
||||
.B 0 |
||||
if Enter is pressed on termination, |
||||
.B 1 |
||||
if Escape is pressed. |
||||
.SH ENVIRONMENT |
||||
.TP |
||||
GRID_FONT |
||||
The X11 font used to display each item in the menu. |
||||
.br |
||||
Default: fixed |
||||
.TP |
||||
GRID_NORMCOLORS |
||||
The foreground, background, and border colors of a label. Syntactically, three blank-separated color values of the form #RRGGBB are expected. |
||||
.br |
||||
Default: #222222 #eeeeee #666666 |
||||
.TP |
||||
GRID_SELCOLORS |
||||
Like GRID_NORMCOLORS, but for the selected label. |
||||
.br |
||||
Default: #ffffff #335577 #447799 |
||||
