Quick Start

Basic Usage

from xbot_form import show_form

# Window title is automatically extracted from schema["title"]
schema = {
    "type": "object",
    "title": "User Registration",  # <- This becomes the window title
    "properties": {
        "name": {"type": "string", "title": "Name"},
        "email": {"type": "string", "title": "Email", "format": "email"},
    },
    "required": ["name", "email"]
}

result = show_form(schema=schema)
print(f"User submitted: {result}")

# Or override with explicit title parameter
result = show_form(schema=schema, title="Custom Window Title")

Builder Pattern (Recommended)

from xbot_form import form_builder, FormCancelledError

try:
    result = (
        form_builder()
        .schema({
            "type": "object",
            "properties": {
                "username": {"type": "string", "title": "Username"},
                "password": {"type": "string", "title": "Password"},
            }
        })
        .ui_schema({
            "password": {"ui:widget": "password"}
        })
        .title("Login")
        .size(600, 400)
        .frameless(corner_radius=16)
        .theme("dark")
        .show()
    )
    print(f"Login: {result}")
except FormCancelledError:
    print("Login cancelled")

Configuration Classes

from xbot_form import (
    show_form_with_config,
    FormConfig,
    WindowOptions,
    DisplayOptions,
    FormCancelledError
)

config = FormConfig(
    schema={
        "type": "object",
        "properties": {
            "task": {"type": "string", "title": "Task Name"},
            "priority": {
                "type": "string",
                "title": "Priority",
                "enum": ["Low", "Medium", "High"]
            }
        }
    },
    window=WindowOptions(
        width=800,
        height=600,
        title="New Task",
        frameless=True,
        corner_radius=12
    ),
    display=DisplayOptions(
        theme="light",
        debug=False
    )
)

try:
    result = show_form_with_config(config)
    print(f"Task created: {result}")
except FormCancelledError:
    print("Cancelled")
