Detailed Description

The placement class for a horizontal list.

See placer_base for more information.

Definition at line 38 of file horizontal_list.hpp.

Constructor & Destructor Documentation

placer_horizontal_list()

gui2::implementation::placer_horizontal_list::placer_horizontal_list ( const unsigned  maximum_rows )

explicit

Definition at line 31 of file horizontal_list.cpp.

References maximum_rows_.

Member Function Documentation

add_item()

void gui2::implementation::placer_horizontal_list::add_item ( const point &  size )

virtual

Adds a item to be placed.

Parameters

size	The required size for the item.

Implements gui2::placer_base.

Definition at line 50 of file horizontal_list.cpp.

References column_, columns_, maximum_rows_, row_, rows_, and utf8::size().

get_origin()

point gui2::implementation::placer_horizontal_list::get_origin ( const unsigned  index ) const

virtual

Gets the origin for an item.

Parameters

index

The index of the item whose origin to return. The index is the index of the call to add_item().

Returns

The origin where to place the widget.

Implements gui2::placer_base.

Definition at line 77 of file horizontal_list.cpp.

References columns_, utf8::index(), maximum_rows_, draw::point(), and rows_.

get_size()

point gui2::implementation::placer_horizontal_list::get_size ( ) const

virtual

Gets the required size of all items.

Returns

The required size.

Implements gui2::placer_base.

Definition at line 70 of file horizontal_list.cpp.

References columns_, draw::point(), and rows_.

initialize()

void gui2::implementation::placer_horizontal_list::initialize ( )

virtual

Initialises the placer.

When the placement needs to be calculated the state often needs to be reset, items are placed, removed or changed visibility causing the old placement to be invalid.

Implements gui2::placer_base.

Definition at line 41 of file horizontal_list.cpp.

columns_

std::vector<std::pair<int, int> > gui2::implementation::placer_horizontal_list::columns_

The pair contains the following values:

• first The origin of a column.
• second The width of a column.

maximum_rows_

unsigned gui2::implementation::placer_horizontal_list::maximum_rows_

private

private

Holds the heights of the rows.
