Description:

The powerwall command controls a Powerwall and determines how MeshTV windows are displayed on it. A Powerwall is a large display that is composed of several smaller displays arranged in a tiled fashion. The mode flag turns the Powerwall on and off. The layout flag determines how the Powerwall will be divided. Note that before the layout can be changed, the Powerwall must be turned off with the mode flag. The layout can then be changed and the Powerwall can be turned on in its new layout.

The remaining flags determine how a MeshTV window is put on the Powerwall. The winset flag sets the Powerwall's active canvas. The active canvas is the canvas on which MeshTV windows are displayed. The active canvas can only be set to values that are valid for the Powerwall's current layout. The follow flag determines whether or not all MeshTV windows will be displayed on the Powerwall's active canvas or if the windows will be displayed on the Powerwall canvas to which they are mapped. MeshTV windows are mapped to Powerwall canvases using mapwin. The mapwin argument associates the specified MeshTV window with the active powerwall canvas. Different MeshTV windows can be mapped to different powerwall canvases by first changing the Powerwall's active canvas with the winset flag and then using mapwin. Any MeshTV window can only be mapped to one Powerwall canvas at a time.

Examples:

# Turn on the powerwall in layout 3.

powerwall layout=3, mode=on

# Map MeshTV windows 1,2,3,4 to powerwall canvas 2.

powerwall follow=off, winset=2, mapwin={1 2 3 4}

# Make all MeshTV windows be drawn in powerwall canvas 1.

powerwall winset=1, follow=on
