It manages windows in tiled, monocle +and floating layouts. Either layout can be applied dynamically, optimising the +environment for the application in use and the task performed. +.P +In tiled layouts windows are managed in a master and stacking area. The master +area on the left contains one window by default, and the stacking area on the +right contains all other windows. The number of master area windows can be +adjusted from zero to an arbitrary number. In monocle layout all windows are +maximised to the screen size. In floating layout windows can be resized and +moved freely. Dialog windows are always managed floating, regardless of the +layout applied. +.P +Windows are grouped by tags. Each window can be tagged with one or multiple +tags. Selecting certain tags displays all windows with these tags. +.P +Each screen contains a small status bar which displays all available tags, the +layout, the title of the focused window, and the text read from the root window +name property, if the screen is focused. A floating window is indicated with an +empty square and a maximised floating window is indicated with a filled square +before the windows title. The selected tags are indicated with a different +color. The tags of the focused window are indicated with a filled square in the +top left corner. The tags which are applied to one or more windows are +indicated with an empty square in the top left corner. +.P +dwm draws a small border around windows to indicate the focus state. +.SH OPTIONS +.TP +.B \-v +prints version information to stderr, then exits. +.SH USAGE +.SS Status bar +.TP +.B X root window name +is read and displayed in the status text area. It can be set with the +.BR xsetroot (1) +command. +.TP +.B Button1 +click on a tag label to display all windows with that tag, click on the layout +label toggles between tiled and floating layout. +.TP +.B Button3 +click on a tag label adds/removes all windows with that tag to/from the view. +.TP +.B Mod1\-Button1 +click on a tag label applies that tag to the focused window. +.TP +.B Mod1\-Button3 +click on a tag label adds/removes that tag to/from the focused window. +.SS Keyboard commands +.TP +.B Mod1\-Shift\-Return +Start +.BR st(1). +.TP +.B Mod1\-p +Spawn +.BR dmenu(1) +for launching other programs. +.TP +.B Mod1\-, +Focus previous screen, if any. +.TP +.B Mod1\-. +Focus next screen, if any. +.TP +.B Mod1\-Shift\-, +Send focused window to previous screen, if any. +.TP +.B Mod1\-Shift\-. +Send focused window to next screen, if any. +.TP +.B Mod1\-b +Toggles bar on and off. +.TP +.B Mod1\-t +Sets tiled layout. +.TP +.B Mod1\-f +Sets floating layout. +.TP +.B Mod1\-m +Sets monocle layout. +.TP +.B Mod1\-space +Toggles between current and previous layout. +.TP +.B Mod1\-j +Focus next window. +.TP +.B Mod1\-k +Focus previous window. +.TP +.B Mod1\-i +Increase number of windows in master area. +.TP +.B Mod1\-d +Decrease number of windows in master area. +.TP +.B Mod1\-l +Increase master area size. +.TP +.B Mod1\-h +Decrease master area size. +.TP +.B Mod1\-Return +Zooms/cycles focused window to/from master area (tiled layouts only). +.TP +.B Mod1\-Shift\-c +Close focused window. +.TP +.B Mod1\-Shift\-space +Toggle focused window between tiled and floating state. +.TP +.B Mod1\-Tab +Toggles to the previously selected tags. +.TP +.B Mod1\-Shift\-[1..n] +Apply nth tag to focused window. +.TP +.B Mod1\-Shift\-0 +Apply all tags to focused window. +.TP +.B Mod1\-Control\-Shift\-[1..n] +Add/remove nth tag to/from focused window. +.TP +.B Mod1\-[1..n] +View all windows with nth tag. +.TP +.B Mod1\-0 +View all windows with any tag. +.TP +.B Mod1\-Control\-[1..n] +Add/remove all windows with nth tag to/from the view. +.TP +.B Mod1\-Shift\-q +Quit dwm. +.SS Mouse commands +.TP +.B Mod1\-Button1 +Move focused window while dragging.

This keeps it fast, secure and simple. +.SH SEE ALSO +.BR dmenu (1), +.BR st (1) +.SH ISSUES +Java applications which use the XToolkit/XAWT backend may draw grey windows +only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early +JDK 1.6 versions, because it assumes a reparenting window manager. Possible workarounds +are using JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or setting the +environment variable +.BR AWT_TOOLKIT=MToolkit +(to use the older Motif backend instead) or running +.B xprop -root -f _NET_WM_NAME 32a -set _NET_WM_NAME LG3D +or +.B wmname LG3D +(to pretend that a non-reparenting window manager is running that the +XToolkit/XAWT backend can recognize) or when using OpenJDK setting the environment variable +.BR _JAVA_AWT_WM_NONREPARENTING=1 . +.SH BUGS +Send all bug reports with a patch to hackers@suckless.org. diff --git a/dwm.c b/dwm.c new file mode 100644 index 0000000..f864936 --- /dev/null +++ b/dwm.c @@ -0,0 +1,2893 @@ +/* See LICENSE file for copyright and license details. + * + * dynamic window manager is designed like any other X client as well.
