    • 











Basic Usage#


The PasswordInput widget provides a simple text entry form and supports a placeholder which is displayed when the value is empty:


password_input = pmui.PasswordInput(label='Password', placeholder='Enter your password here...')
password_input








PasswordInput.value returns a string type that can be read out and set like other widgets:


password_input.value











Value Input#


The PasswordInput.value is updated after an enter_pressed event or when switching focus, i.e. when clicking or tabbing away from the widget. To get the current value after every keystroke you can inspect the value_input instead:


value = pmui.PasswordInput(label='Value Input', value='Hello W')
value_input = pmui.PasswordInput(label='Value Input', value='Hello W')

pmui.Column(
    pmui.Row(value, pmui.Typography(value.param.value)),
    pmui.Row(value_input, pmui.Typography(value_input.param.value_input))
)












Maximum Length#


The max_length controls the maximum number of characters that can be entered:


pmui.PasswordInput(label='Password (max_length=12)', max_length=12)












Error State#


The error_state parameter allows setting of the message that is displayed if validation of the input fails.


pmui.PasswordInput(label='PasswordInput (invalid entry)', error_state=True)












Disabled and Loading#


Like other widgets, the PasswordInput can be disabled and/or show a loading indicator.


pmui.PasswordInput(
    label='Text Input', disabled=True, loading=True,
)












Color Options#


You can set the color parameter to visually distinguish the PasswordInput when active. Available options include “default”, “primary”, “secondary”, “error”, “info”, “success”, “warning”, “light”, “dark”, and “danger”:


pmui.FlexBox(
    *[pmui.PasswordInput(label=color, color=color) for color in pmui.PasswordInput.param.color.objects]
)












Size#


The size parameter allows toggling between “small” and “medium” (default) sized input fields:


pmui.FlexBox(
    pmui.PasswordInput(label='Small', size="small"),
    pmui.PasswordInput(label='Medium', size="medium"),
)












Variant#


The variant parameter controls the visual style of the input. Choose from “filled”, “outlined” (default), or “standard”:


pmui.FlexBox(
    pmui.PasswordInput(label='Filled', variant="filled"),
    pmui.PasswordInput(label='Outlined', variant="outlined"),
    pmui.PasswordInput(label='Standard', variant="standard"),
)
