tile <-> border: int

Distance between the object tiled and its reserved area.

See also

window->border

tile -> can_resize: [bool]

This variable is used by class frame to deal with user-initiated resize of the subwindow layout. Initially it is default, When requested and it is default tile<-can_resize sets it to @on if this tile is stretchable in the direction of its tile<-super and there is at least one stretchable tile below or right of this tile.

See also tile->hor_stretch, tile->hor_shrink, tile->ver_stretch and tile->ver_shrink.

tile <-> hor_shrink: int

Encouragement to decrease the width of this tile. When multiple tiles are related left-to-right, the system will compute the sum of the tile<-ideal_width’s of the stacked tiles. If this sum is equal to the desired total width the stretch- and shrink-parameters are ignored. If the sum is smaller than the desired width tile<-hor_stretch is considered. Finally, if the sum is larger than the desired total width the system first attempts to shrink all windows that have tile<-hor_shrink > 0 proportional to their tile<-hor_shrink value. If this does not make the total width small enough, all windows with tile<-hor_shrink == 0 are made equally less wide.

Defaults: The default value is 100.

tile <- members: chain*

If a tile is not directly managing an object (leaf-tile) it is managing a horizontal or vertical stack of subtiles. These subtiles are in the chain tile<-members. Each of the subtiles’ tile<-super points to this tile object. The variable tile<-orientation is set to either horizontal or vertical.

A tile that manages a number of sub-tiles is normally created by its sub-tiles:

?- new(X, tile(box(100, 100))),
   new(Y, tile(box(200, 100))),
   send(X, right, Y).

Will create two tiles and a third, which is a tile with tile<-orientation: horizontal and tile<-members the X and Y tiles.

tile-super

tile <- object: object*

Leaf-tiles directly manage the area of an object. This may be any object provided it implements tile<-width, tile<-height and tile->set.

tile <- orientation: {none,horizontal,vertical}

Direction of adjacent sub-tiles. If none, the tile is a leaf tile controlling an tile<-object. If horizontal, the tile<-members are places left-to-right. If vertical they are placed top-to-bottom.

tile <- super: tile*
