Detailed Description

The placement class for a horizontal list.

See placer_base for more information.

Definition at line 37 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 30 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
sizeThe required size for the item.

Implements gui2::placer_base.

Definition at line 49 of file horizontal_list.cpp.

References column_, columns_, maximum_rows_, row_, rows_, point::x, and point::y.

◆ get_origin()

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

Gets the origin for an item.

Parameters
indexThe 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 76 of file horizontal_list.cpp.

References columns_, maximum_rows_, 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 69 of file horizontal_list.cpp.

References columns_, 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 40 of file horizontal_list.cpp.

Member Data Documentation

◆ column_

unsigned gui2::implementation::placer_horizontal_list::column_
private

◆ columns_

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

Holds the column sizes.

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

The maximum number of rows to use.

This value is determined by the parallel_items parameter of placer_base::build).

◆ rows_

std::vector<int> gui2::implementation::placer_horizontal_list::rows_
private

Holds the heights of the rows.

Definition at line 69 of file horizontal_list.hpp.
