icewmhint - set IceWM hints by window class and instance




icewmhint is a utility for passing IceWM hints to icewm(1). icewm uses these hints for the first X11 client which is subsequently started. They take precedence over hints from the icewm-winoptions(1) file.

A hint is a triplet consisting of a class.instance, an IceWM winoption and its value. Multiple hints can be given per invocation of icewmhint.

The hints are communicated over the "_ICEWM_WINOPTHINT" property on the root window. icewmhint appends hints to this property, while icewm removes the property after reading it.


icewmhint recognizes the following options:


Only one command option can be specified per invocation. If no command option is specified, argument parsing and processing is performed.

Print a brief usage statement to stdout and exit.
Print the program version to stdout and exit.
Print copying permissions to stdout for the program and exit.


Specifies the X11 DISPLAY. If unspecified, defaults to $DISPLAY.


The following three arguments are required for each hint.

Specifies the ICCCM 2.0 WM_CLASS property in terms of resource class and resource name separated by a period ("."). For example: "XTerm.xterm". Just the resource class or resource name without a dot is also acceptable, like "XTerm" or "xterm".
Specifies the OPTION to affect.
Gives the VALUE for the option.

Multiple hints can be given.


General option arguments are normally associated with GNOME WinWM/WMH hints (except for the tray option argument).

Specifies the icon name for windows of CLASS.INSTANCE. NAME should be the name of the icon. icewm(1) will use its usual method to locate the icon. The default is the name provided by window manager hints.
Specifies the workspace on which a window of CLASS.INSTANCE will be initially placed. The default is the current workspace. WORKSPACE should be a workspace number counting from 0.
Specifies the initial geometry for windows of the given CLASS.INSTANCE. GEOMETRY must be a geometry that can be parsed by XParseGeometry(3). The default is the geometry provided by window manager hints.
The sorting order of task buttons and tray icons. The default value is zero. Increasing positive values go farther right, while decreasing negative values go farther left. The order option applies to the task pane, the tray pane and the system tray.
Set the _NET_WM_WINDOW_OPACITY property if NUMBER is a value between 1 and 100. NUMBER is interpreted as percentage of maximum opaqueness.
The layer is a similar concept to the layer specified by GNOME/WMH and implied by NetWM/EWMH. It is in this case however specific to icewm(1).

This command option specifies the layer to be associated with a CLASS.INSTANCE. The default is the "Normal" layer. VALUE is either a layer number or a symbolic layer name. Symbolic layer names are:

    Desktop    (0)  desktop window layer.
    Below      (2)  below normal windows.
    Normal     (4)  default window layer.
    OnTop      (6)  above normal windows.
    Dock       (8)  docks (panels and edge displays).
    AboveDock (10)  above docks.
    Menu      (12)  above everything else.
Specifies the tray handling to be applied to windows with CLASS.INSTANCE. This option is specific to icewm(1) and sets the "_ICEWM_TRAY" property associated with the window. The default is "Ignore". VALUE can be an option number or a symbolic name as follows:

    Ignore     (0)  only in task list.
    Minimized  (1)  icon in tray, task list unminimized.
    Exclusive  (2)  only in tray, not in task list.


Specifies which functions are disabled or enabled (0/1) for windows with CLASS.INSTANCE. All functions have a default value of enabled (1) unless overridden by the application. The Motif-like functions are as follows:

    fClose     can be closed:        (default: 1).
    fHide      can be hidden:        (default: 1).
    fMaximize  can be maximized:     (default: 1).
    fMinimize  can be minimized:     (default: 1).
    fMove      can be moved:         (default: 1).
    fResize    can be resized:       (default: 1).
    fRollup    can be shaded:        (default: 1).


Specifies which decorations are disabled or enabled (0/1) for windows with CLASS.INSTANCE. All decor options have a default value of enabled (1) unless overridden by the application. The Motif-like decorations are as follows:

    dBorder    has border:           (default: 1).
    dClose     has close button:     (default: 1).
    dDepth     has depth button:     (default: 1).
    dHide      has hide button:      (default: 1).
    dMaximize  has maximize button:  (default: 1).
    dMinimize  has minimize button:  (default: 1).
    dResize    has resize grips:     (default: 1).
    dRollup    has shade button:     (default: 1).
    dSysMenu   has window menu:      (default: 1).
    dTitleBar  has title bar:        (default: 1).


Specifies which advanced features to be enabled/disabled (1/0) for windows with CLASS.INSTANCE. All advanced features have a default value of disabled (0) unless overridden by the application. The advanced features are as follows:

    allWorkspaces             on all workspaces.
    appTakesFocus             let application take focus.
    doNotCover                limits workspace if sticky.
    doNotFocus                do not focus.
    forcedClose               no close dialog.
    fullKeys                  provided more keys.
    ignoreNoFocusHint         focus even no-input.
    ignorePagerPreview        do not show in pager preview.
    ignorePositionHint        place automatically.
    ignoreQuickSwitch         not on quick switch.
    ignoreTaskBar             not on task bar.
    ignoreUrgentHint          ignore urgent hints.
    ignoreWinList             not on window list.
    noFocusOnAppRaise         no focus on raise.
    noFocusOnMap              do not focus when mapped.
    noIgnoreTaskBar           on task bar.
    startFullscreen           start full screen.
    startMaximized            start maximized.
    startMaximizedHorz        start maximized horizontal.
    startMaximizedVert        start maximized vertical.
    startMinimized            start minimized.
