FloatField

This is a class.

It is used to create FloatField.

• It inherits from :ref: TextField <textField_title> and overrides a few methods so that it’s value is of type float

• Everything valid for TextField is valid for FloatField, it has same events.

Following code is very similar to the code of TextField.

code:

from boss.ui_creator import UICreator, RectData

def onTextChanged(caller):
    print('textChanged', f'value - {caller.value}, text - {caller.text}')

def onValueChanged(caller):
    print('valueChanged', f'value - {caller.value}, text - {caller.text}')

def onEnterPressed(caller):
    print('enterPressed', f'value - {caller.value}, text - {caller.text}')

def ui_elements(op):
    btn_width, btn_height = 150, 40
    rd = RectData(
        op.uip.mouse_x,
        op.uip.mouse_y - btn_height,
        btn_width,
        btn_height
    )

    floatField = UICreator.floatField(
        op,
        rectData=rd,
        value=100,
        onTextChange=onTextChanged,
        onValueChange=onValueChanged,
        onEnterPress=onEnterPressed,
        param='This can be any python object'
    )
    # these are methods for adding callback after creation
    # floatField.add_onTextChange(onTextChanged)
    # floatField.add_onValueChange(onValueChanged)
    # floatField.add_onEnterPress(onEnterPressed)

• By default onWheelUp and onWheelDown callbacks are added. So rolling mouse will change the value by .1

• You can type simple math expression. eg, 1+2, value = 3.0 , 9/2, value = 4.5

• by default, value has precision of 3. So, for 3.12345 becomes 3.123
