Class Flex

org.joshvm.ui.layout.Flex

All Implemented Interfaces:

Layout

public class Flex
extends Object
implements Layout

Flex layout can arrange items into rows or columns (tracks), handle wrapping, adjust the spacing between the items and tracks, handle grow to make the item(s) fill the remaining space with respect to min/max width and height.

Flex layout will put an item into a new line if forceNewTrack is used.

Flex grow if set on an item it will grow to fill the remaining space on the track. The available space will be distributed among items respective to their grow value (larger value means more space).
Grow value can be set with setFlexGrow.

setRowPadding and setColumnPadding can be used to modify the space between the rows and columns or the items on a track.

Field Summary

Fields

Modifier and Type	Field and Description
static int	FLEX_ALIGN_CENTER simply center
static int	FLEX_ALIGN_END means right on a horizontally and bottom vertically
static int	FLEX_ALIGN_SPACE_AROUND items are evenly distributed in the track with equal space around them.
static int	FLEX_ALIGN_SPACE_BETWEEN items are evenly distributed in the track: first item is on the start line, last item on the end line.
static int	FLEX_ALIGN_SPACE_EVENLY items are distributed so that the spacing between any two items (and the space to the edges) is equal.
static int	FLEX_ALIGN_START means left on a horizontally and top vertically
static int	FLEX_FLOW_TYPE_COLUMN Place the children in a column (track) without wrapping
static int	FLEX_FLOW_TYPE_COLUMN_WRAP Place the children in a column (track) with wrapping
static int	FLEX_FLOW_TYPE_ROW Place the children in a row (track) without wrapping

Field Detail

FLEX_FLOW_TYPE_ROW

public static final int FLEX_FLOW_TYPE_ROW

Place the children in a row (track) without wrapping

See Also:

Constant Field Values

FLEX_FLOW_TYPE_COLUMN

public static final int FLEX_FLOW_TYPE_COLUMN

Place the children in a column (track) without wrapping

See Also:

Constant Field Values

FLEX_FLOW_TYPE_ROW_WRAP

public static final int FLEX_FLOW_TYPE_ROW_WRAP

Place the children in a row (track) with wrapping

If there is no more space in the track a new track is started

See Also:

Constant Field Values

FLEX_FLOW_TYPE_COLUMN_WRAP

public static final int FLEX_FLOW_TYPE_COLUMN_WRAP

Place the children in a column (track) with wrapping

If there is no more space in the track a new track is started

See Also:

Constant Field Values

FLEX_ALIGN_START

public static final int FLEX_ALIGN_START

means left on a horizontally and top vertically

See Also:

Constant Field Values

FLEX_ALIGN_END

public static final int FLEX_ALIGN_END

means right on a horizontally and bottom vertically

See Also:

Constant Field Values

FLEX_ALIGN_CENTER

public static final int FLEX_ALIGN_CENTER

simply center

See Also:

Constant Field Values

FLEX_ALIGN_SPACE_EVENLY

public static final int FLEX_ALIGN_SPACE_EVENLY

items are distributed so that the spacing between any two items (and the space to the edges) is equal.

See Also:

Constant Field Values

FLEX_ALIGN_SPACE_AROUND

public static final int FLEX_ALIGN_SPACE_AROUND

items are evenly distributed in the track with equal space around them.

Note that visually the spaces aren’t equal, since all the items have equal space on both sides. The first item will have one unit of space against the container edge, but two units of space between the next item because that next item has its own spacing that applies.

See Also:

Constant Field Values

FLEX_ALIGN_SPACE_BETWEEN

public static final int FLEX_ALIGN_SPACE_BETWEEN

items are evenly distributed in the track: first item is on the start line, last item on the end line.
