Expand description

Trait containing all Box methods.

Implementors

Box, ShortcutsGroup, ShortcutsSection

Required methods

Adds @child as the last child to @self.

child

the Widget to append

Gets the value set by gtk_box_set_baseline_position().

Returns

the baseline position

Returns whether the box is homogeneous (all children are the same size).

Returns

true if the box is homogeneous.

Gets the value set by gtk_box_set_spacing().

Returns

spacing between children

Inserts @child in the position after @sibling in the list of @self children.

If @sibling is None, insert @child at the first position.

child

the Widget to insert

sibling

the sibling after which to insert @child

Adds @child as the first child to @self.

child

the Widget to prepend

Removes a child widget from @self.

The child must have been added before with append(), prepend(), or insert_child_after().

child

the child to remove

Moves @child to the position after @sibling in the list of @self children.

If @sibling is None, move @child to the first position.

child

the Widget to move, must be a child of @self

sibling

the sibling to move @child after

Sets the baseline position of a box.

This affects only horizontal boxes with at least one baseline aligned child. If there is more vertical space available than requested, and the baseline is not allocated by the parent then @position is used to allocate the baseline with respect to the extra space available.

position

a BaselinePosition

Sets whether or not all children of @self are given equal space in the box.

homogeneous

a boolean value, true to create equal allotments, false for variable allotments

Sets the number of pixels to place between children of @self.

spacing

the number of pixels to put between children
