Components

Change Theme (As simple button)

More info

Internally it uses the underlying pills component that streamlit uses to render the real pills component. So it has even more flexibility than the native streamlit pills button, and we add some radio button capabilities to it.

Examples: Change Theme with Button

from streamlit_plugins.components.theme_changer import st_theme_changer

st_theme_changer()

If you want to use more than one theme changer in your app, you will have to enable rerun comlpete application in order to update the state of buttons, this is because streamlit is not prepare to rerun other fragments, seperatlly, when the streamlit dev team enable this, we can improve the performance of the component.

Note that if tou rerun the whole app, depending or what tasks are you doing, it can be slow, so use it with caution. We recommend set to rerun_whole_st=True and use only one st_theme_changer in your app.

st_theme_changer(rerun_whole_st=True)

with st.sidebar:
    st_theme_changer(render_mode="pills", rerun_whole_st=True)

The above code only will change between the light/dark themes by default in streamlit. But here is the game changer, on in that case the theme changer, not only you can change between the defaults, YOU CAN DEFINE YOUR OWN THEMES, yes, more than 2. All the properties you can change are defined here. Theme props

from streamlit_plugins.components.theme_changer import st_theme_changer
from streamlit_plugins.components.theme_changer.entity import ThemeInfo, ThemeInput, ThemeBaseLight, ThemeBaseDark
theme_data = dict(
    soft_light=ThemeInput(
        name="Soft Sunrise",
        icon=":material/sunny_snowing:",
        order=0,
        themeInfo=ThemeInfo(
            base=ThemeBaseLight.base,

    ),

        themeInfo=ThemeInfo(
            base=ThemeBaseLight.base,
            primaryColor="#FF0004",
            backgroundColor="#F9F9E0",

            bodyFont=ThemeBaseLight.bodyFont,
            codeFont=ThemeBaseLight.codeFont,
            fontFaces=ThemeBaseLight.fontFaces,
        )
    )
)
st_theme_changer(themes_data=theme_data, render_mode="init", default_init_theme_name="soft_dark")

st_theme_changer(themes_data=theme_data, rerun_whole_st=True)
with st._bottom:
   st_theme_changer(
      themes_data=theme_data, render_mode="pills",
      rerun_whole_st=True, key="first_pills"
   )

with st.sidebar:
    st_theme_changer(
        themes_data=theme_data, render_mode="pills",
        rerun_whole_st=True, key="secondary_pills"
    )

There is another parameter that you can customize, is a sleep parameter, because the time it costs javascript to send the message in other to change the change, maybe in some cases your javascript streamlit page is slowly and the change theme doesn't queue your request to change the theme, so you can customize this sleep in order to wait for the javascript to be ready to change the theme.

# Parameter in seconds
st_theme_changer(timeout_rendering_theme_change=0.3)
