The base definitions and classes shared by all TcMenu renderers.
This file contains the common code for rendering onto displays, making it much easier to implement a renderer.
typedef void(* RendererCallbackFn) (unsigned int currentValue, RenderPressMode userClicked) |
Used to take over rendering for a period of time. Normally one calls renderer.takeOverDisplay(..) with a reference to a function meeting this spec. Whenever the callback occurs the current value of the rotary encoder is provided along with the state of the menu select switch.
currentValue | is the current value of the rotary encoder |
userClicked | if the user clicked the select button |
typedef void(* ResetCallbackFn) () |
Used to indicate when the renderer is about to be reset, you could use this to do custom rendering when the menu is not active, for example taking over the display until some condition is met.
enum RenderPressMode : uint8_t |
an enumeration of possible values that are given to either custom render functions or used internally by renderers to describe the state of the select button. Values should be self explanatory. High compatibility with bool for determining if the button is pressed.
Enumerator | |
---|---|
RPRESS_NONE | The select button is not pressed |
RPRESS_PRESSED | The select button has been pressed |
RPRESS_HELD | The selected button is held down |
enum MenuRedrawState : uint8_t |
Used by renderers to determine how significant a redraw is needed at the next redraw interval. They are prioritised in ascending order, so a more complete redraw has a higher number.
bool isItemActionable | ( | MenuItem * | item | ) |
Checks if a given menu item can have an action performed on it.
