Detailed Description

The NummericUpDown Gui Element

Typedef Documentation

typedef void(* NUMUPDOWN_CALLBACK) (void *numupdown, int16_t value)

Prototype for Event Listeners (called when the NummericUpDown value has changed)

Note: You should NOT execute long running things in this callback nor should you update the gui. But you can call gui_screen_navigate() for instance.

Parameters

numupdown	The pointer to the NUMUPDOWN_STRUCT where to corresponding NummericUpDown has changed it's value
value	The new value of the NummericUpDown

numupdown A Pointer to the preinitialized NUMUPDOWN_STRUCT

Returns: true on success

numupdown A Pointer to the NUMUPDOWN_STRUCT

Here is the call graph for this function:

void gui_numupdown_remove ( NUMUPDOWN_STRUCT * numupdown )
