Detailed Description

Used by the BaseGraphicalRenderer class to work out how to draw an item, which grid position it is in etc. This version does not implement icons, nor does it implement overriding of display properties, it is intended for LCDs.

This is used by non graphical displays to allow grid configurations while not providing the complex support for display properties at different levels. This makes the class much simpler and should use far less memory on devices.

Member Function Documentation

configFor()

ItemDisplayProperties* tcgfx::NullItemDisplayPropertiesFactory::configFor ( MenuItem *  pItem, ItemDisplayProperties::ComponentType  compType  )

inlineoverridevirtual

Returns the configuration for the parameters below, it should never return nullptr.

Parameters

pItem	the item or null for default
compType	the component type to get the rendering for

Returns

the properties for a given component.

Implements tcgfx::ItemDisplayPropertiesFactory.

configForCurrentSub()

ItemDisplayProperties* tcgfx::NullItemDisplayPropertiesFactory::configForCurrentSub ( ItemDisplayProperties::ComponentType  compType )

inlineoverridevirtual

Returns the configuration for the parameters below, it should never return nullptr, but the difference to configFor is that this version will not check at the item level so is safe when there are overrides at both the item and the sub level.

Parameters

compType

the type of component to get the rendering for

Returns

the properties for the given component.

Implements tcgfx::ItemDisplayPropertiesFactory.

iconForMenuItem()

DrawableIcon* tcgfx::NullItemDisplayPropertiesFactory::iconForMenuItem ( uint16_t  id )

inlineoverridevirtual

Returns the icon associated with the menu item ID, there are two special IDs for the edit and active icons

Parameters

id	the menu item ID or the special ID for edit or active icon

Returns

the icon or nullptr if not available

Implements tcgfx::ItemDisplayPropertiesFactory.

getSelectedColor()

color_t tcgfx::NullItemDisplayPropertiesFactory::getSelectedColor ( ItemDisplayProperties::ColorType  colorType, bool  isUnderCursor = false  )

inlineoverridevirtual

Get the selected color for a given palette entry

Parameters

colorType

Returns

Implements tcgfx::ItemDisplayPropertiesFactory.

gridPositionForItem()

GridPositionWithId* tcgfx::NullItemDisplayPropertiesFactory::gridPositionForItem ( MenuItem *  pItem )

inlineoverridevirtual

Get the grid item for a given position if it is available

Parameters

pItem

the item to get the grid position for

Returns

the grid position if available

Implements tcgfx::ItemDisplayPropertiesFactory.

addGridPosition()

void tcgfx::NullItemDisplayPropertiesFactory::addGridPosition ( MenuItem *  item, const GridPosition &  position  )

inlineoverridevirtual

add a new grid position for a given menu item

Parameters

item	the menu item the position is for
position	the position to record

Implements tcgfx::ItemDisplayPropertiesFactory.
