Values

When an item is created, it creates an associated value by default. Values can be shared between items with the same underlying value type. This is accomplished by using the source keyword. One of the benefits of this is to have multiple items control the same value.

Values are retrieved from the value get_value.

Values can be changed manually using set_value.

import dearpygui.dearpygui as dpg

dpg.create_context()

with dpg.window(label="Tutorial"):
    dpg.add_checkbox(label="Radio Button1", tag="R1")
    dpg.add_checkbox(label="Radio Button2", source="R1")

    dpg.add_input_text(label="Text Input 1")
    dpg.add_input_text(label="Text Input 2", source=dpg.last_item(), password=True)

dpg.create_viewport(title='Custom Title', width=800, height=600)
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()

Value Items

There are several “Value” items that can be used. These are items that have no visual component. These include:

• mvBoolValue

• mvColorValue

• mvDoubleValue

• mvDouble4Value

• mvFloatValue

• mvFloat4Value

• mvFloatVectValue

• mvIntValue

• mvInt4Value

• mvSeriesValue

• mvStringValue

Basic usage can be found below:

import dearpygui.dearpygui as dpg

dpg.create_context()

with dpg.value_registry():
    dpg.add_bool_value(default_value=True, tag="bool_value")
    dpg.add_string_value(default_value="Default string", tag="string_value")

with dpg.window(label="Tutorial"):
    dpg.add_checkbox(label="Radio Button1", source="bool_value")
    dpg.add_checkbox(label="Radio Button2", source="bool_value")

    dpg.add_input_text(label="Text Input 1", source="string_value")
    dpg.add_input_text(label="Text Input 2", source="string_value", password=True)

dpg.create_viewport(title='Custom Title', width=800, height=600)
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()
