- ID: Unique number that identifies the object.
- Name: User-definable name for the object. It can be used with 86HMI API.
Geometry:
- X: Object X coordinate.
- Y: Object Y coordinate.
- Width: Object width.
- Height: Object height.
Options:
- Value Type: NumberInput value type, integer or decimal point.
- Keyboard: Set whether the virtual keyboard is displayed. The virtual keyboard appears when the user clicks the NumberInput box to enter a number.
- TextFont: Choose from 6 default font styles. For font configuration instructions, please refer to Theme Management.
- Order: Object order. It can adjust the object order by up/down, which can be viewed on the Object List.
API Functions

bool numberInputApplied(char* name);
Parameters
[in] id
Object ID.[in] name
Object Name.
Return
Bool. Determine NumberInput is applied.
Example
#include "myhmi.h" void setup() { Hmi.begin(); // ... } void loop() { BEGIN_HMI_EVENT_PROC { if (Hmi.numberInputApplied(p1nin1)) { Serial.println(Hmi.getNumberInputInteger(p1nin1)); } } END_HMI_EVENT_PROC }
numberInputCanceled()
Description
Determine NumberInput is canceled.
Syntax
bool numberInputCanceled(lv_obj_t* id);
bool numberInputCanceled(char* name);
Parameters
[in] id
