Detailed Description

A vertical list widget with text entries.

Note: items you add to a list are not kept after the the list is in was removed (i.e. you need to add items everytime the screen is shown)

Member Function Documentation

◆ addColumn()

void GUIEngine::ListWidget::addColumn	(	irr::core::stringw	col,
		int	proportion = `1`
	)

inline

Columns are persistent across multiple "clear" add/remove cycles.

clearColumns clear them immediately.

Parameters

proportion A column with proportion 2 will be twice as large as a column with proportion 1

◆ addItem()

void ListWidget::addItem	(	const std::string &	internal_name,
		const irr::core::stringw &	name,
		const int	icon = `-1`,
		bool	center = `false`
	)

add an item to the list

Parameters

name	user-visible, potentially translated, name of the item
icon	ID of the icon within the icon bank. Only used if an icon bank was passed.

Precondition: may only be called after the widget has been added to the screen with add()

◆ clear()

void ListWidget::clear ( )

erases all items in the list, don't clear header

Precondition: may only be called after the widget has been added to the screen with add()

◆ clearColumns()

void ListWidget::clearColumns ( )

clear the header

Precondition: may only be called after the widget has been added to the screen with add()

◆ createHeader()

void ListWidget::createHeader ( )

create a header based on m_header

Precondition: may only be called after the widget has been added to the screen with add()

◆ getItemCount()

int ListWidget::getItemCount ( ) const

Returns: the number of items in the list

Precondition: may only be called after the widget has been added to the screen with add()

◆ getSelectionID()

int ListWidget::getSelectionID ( ) const

Returns: the index of the selected element within the list, or -1 if none

Precondition: may only be called after the widget has been added to the screen with add()

◆ getSelectionInternalName()

std::string ListWidget::getSelectionInternalName ( )

Returns: the text of the selected item

Precondition: may only be called after the widget has been added to the screen with add()

◆ markItemRed() [1/2]

void ListWidget::markItemRed	(	const int	id,
		bool	red = `true`
	)

Make an item red to mark an error, for instance.

Precondition: may only be called after the widget has been added to the screen with add()

◆ markItemRed() [2/2]

void GUIEngine::ListWidget::markItemRed	(	const std::string &	internalName,
		bool	red = `true`
	)

inline

Make an item red to mark an error, for instance.

Precondition: may only be called after the widget has been added to the screen with add()

◆ renameCell() [1/2]

void ListWidget::renameCell	(	const int	row_num,
		const int	col_num,
		const irr::core::stringw &	newName,
		const int	icon = `-1`
	)

rename an item and/or change its icon based on its ID

Precondition: may only be called after the widget has been added to the screen with add()

◆ renameCell() [2/2]

void GUIEngine::ListWidget::renameCell	(	const std::string	internalName,
		const int	col_num,
		const irr::core::stringw &	newName,
		const int	icon = `-1`
	)

inline

rename an item and/or change its icon based on its internal name

Precondition: may only be called after the widget has been added to the screen with add()

◆ setActive()

void ListWidget::setActive ( bool active = true )

virtual

Sets an widget to be either activated or deactivated (i.e.

greyed out)

Parameters

active Active (true) or deactive (false). Defaults to true.

Reimplemented from GUIEngine::Widget.

◆ setIcons()

void ListWidget::setIcons	(	irr::gui::STKModifiedSpriteBank *	icons,
		float	scale = `-1.0f`
	)

set the icon bank to use for list entries.

The height of list entries will be ajusted to the size of the highest icon. Icons must therefore be at least as high as text.

Note: the list widget does NOT take ownership of the bank, dso you must delete it when you're done with it (but do not delete it when the list widget is still active)

Precondition: may only be called after the widget has been added to the screen with add()

◆ setSelectionID()

void ListWidget::setSelectionID ( const int index )

change the selected item

Parameters

index the index of the element to select within the list, or -1 to select nothing

Precondition: may only be called after the widget has been added to the screen with add()

◆ transmitEvent()

EventPropagation ListWidget::transmitEvent	(	Widget *	w,
		const std::string &	originator,
		const int	playerID
	)

virtual

Override callback from Widget.

Allows sort icon to change depending on sort order

Reimplemented from GUIEngine::Widget.
