@Generated("io.github.jwharm.JavaGI")
public class WrapLayout
extends LayoutManager
implements Orientable

A box-like layout that can wrap into multiple lines.

AdwWrapLayout is similar to BoxLayout, but can wrap lines when the widgets cannot fit otherwise. Unlike FlowBox, the children aren't arranged into a grid and behave more like words in a wrapping label.

Like GtkBoxLayout, AdwWrapLayout is orientable and has spacing:

• WrapLayout:child-spacing between children in the same line;
• WrapLayout:line-spacing between lines.

Note Unlike GtkBoxLayout, AdwWrapLayout cannot follow the CSS border-spacing property. Use the [property@WrapLayout:natural-line-length] property to determine the layout's natural size, e.g. when using it in a [class@Gtk.Popover]. Normally, a horizontal AdwWrapLayout wraps left to right and top to bottom for left-to-right languages. Both of these directions can be reversed, using the [property@WrapLayout:pack-direction] and [property@WrapLayout:wrap-reverse] properties. Additionally, the alignment of each line can be controlled with the [property@WrapLayout:align] property. Lines can be justified using the [property@WrapLayout:justify] property, filling the entire line by either increasing child size or spacing depending on the value. Set [property@WrapLayout:justify-last-line] to justify the last line as well. By default, AdwWrapLayout wraps as soon as the previous line cannot fit any more children without shrinking them past their natural size. Set [property@WrapLayout:wrap-policy] to [enum@Adw.WrapPolicy.MINIMUM] to only wrap once all the children in the previous line have been shrunk to their minimum size. To make each line take the same amount of space, set [property@WrapLayout:line-homogeneous] to TRUE. Spacing and natural line length can scale with the text scale factor, use the [property@WrapLayout:child-spacing-unit], [property@WrapLayout:line-spacing-unit] and/or [property@WrapLayout:natural-line-length-unit] properties to enable that behavior. See [class@WrapBox].

Constructor Details

WrapLayout

public WrapLayout(MemorySegment address)

Create a WrapLayout proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

WrapLayout

public WrapLayout()

Creates a new WrapLayout.

Method Details

getType

public static Type getType()

Get the GType of the WrapLayout class

Returns:

the GType

asParent

protected WrapLayout asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class LayoutManager

getAlign

public float getAlign()

the child alignment

setAlign

public void setAlign(float align)

Sets the alignment of the children within each line.

0 means the children are placed at the start of the line, 1 means they are placed at the end of the line. 0.5 means they are placed in the middle of the line.

Alignment is only used when WrapLayout:justify is set to ADW_JUSTIFY_NONE, or on the last line when the WrapLayout:justify-last-line is FALSE.

Parameters:

align - the child alignment

Since:

1.7

setChildSpacing

public void setChildSpacing(int childSpacing)

Sets the spacing between widgets on the same line.

See WrapLayout:child-spacing-unit.

Parameters:

childSpacing - the child spacing

Since:

1.7

setChildSpacingUnit

public void setChildSpacingUnit(LengthUnit unit)

Sets the length unit for child spacing.

Allows the spacing to vary depending on the text scale factor.

See WrapLayout:child-spacing.

Parameters:

unit - the length unit

Since:

1.7

setJustify

public void setJustify(JustifyMode justify)

Sets whether and how each complete line should be stretched to fill the entire widget.

If set to ADW_JUSTIFY_FILL, each widget in the line will be stretched, keeping consistent spacing, so that the line fills the entire widget.

If set to ADW_JUSTIFY_SPREAD, the spacing between widgets will be increased, keeping widget sizes intact. The first and last widget will be aligned with the beginning and end of the line. If the line only contains a single widget, it will be stretched regardless.

If set to ADW_JUSTIFY_NONE, the line will not be stretched and the children will be placed together within the line, according to WrapLayout:align.

By default this doesn't affect the last line, as it will be incomplete. Use WrapLayout:justify-last-line to justify it as well.

Parameters:

justify - the justify mode

Since:

1.7

setJustifyLastLine

public void setJustifyLastLine(boolean justifyLastLine)

Sets whether the last line should be stretched to fill the entire widget.

See WrapLayout:justify.

Parameters:

justifyLastLine - whether to justify the last line

Since:

1.7

public void setLineHomogeneous(boolean homogeneous)

Sets whether all lines should take the same amount of space.

Parameters:

homogeneous - whether lines should be homogeneous

Since:

setLineSpacing

public void setLineSpacing(int lineSpacing)

Sets the spacing between lines.

See WrapLayout:line-spacing-unit.

Parameters:

lineSpacing - the line spacing

Parameters:

unit - the length unit

setWrapPolicy

public void setWrapPolicy(WrapPolicy wrapPolicy)

Sets the policy for line wrapping.

If set to ADW_WRAP_NATURAL, the box will wrap to the next line as soon as the previous line cannot fit any more children without shrinking them past their natural size.

If set to ADW_WRAP_MINIMUM, the box will try to fit as many children into each line as possible, shrinking them down to their minimum size before wrapping to the next line.

Parameters:
