一个flet的扩展组件库,提供一些常用组件及功能。

ComboBox

用于简化Dropdown的开发过程,option可以使用列表设置,如["Hello", "World"]

import flet
import fleter


def build(page: flet.Page):
    item = []
    for index in range(20):
        item.append(f"item{index}")
    page.add(fleter.ComboBox(options=item))
    page.update()

flet.app(target=build)

设置选项的状态

很简单,我们只要将选项设置为元组或列表即可。如($name, $disabled)即可

import flet
import fleter


def build(page: flet.Page):
    item = [
        "normal",  # 默认状态
        ("disabled", True),  # 失效状态
        ("active", False),  # 激活状态
    ]
    page.add(fleter.ComboBox(options=item))
    page.update()

flet.app(target=build)

Editor

文本编辑器。

import flet
import fleter


def build(page: flet.Page):
    editor = fleter.Editor()
    
    page.add(editor)
    page.add(fleter.ComboBox(options=item))
    page.update()

flet.app(target=build)

HeaderBar

用于快速设置窗口标题栏。

常规

import flet
import fleter


def build(page: flet.Page):
    titlebar = fleter.HeaderBar(page, title="Hello World")
    page.add(
        titlebar
    )
    page.update()

flet.app(target=build)

标题栏靠左-切换主题按钮

import flet
import fleter


def build(page: flet.Page):
    titlebar = fleter.HeaderBar(page, title="Hello World", title_align="left")
    titlebar.controls.insert(1, fleter.SwichThemeButton(page))
    page.add(
        titlebar
    )
    page.update()

flet.app(target=build)

获取标题栏里面的关闭按钮

可以在组件中找到close_button的属性,并对其进行设置。(前提是设置has_close属性为True

import flet
import fleter


def build(page: flet.Page):
    titlebar = fleter.HeaderBar(page)
    print(titlebar.close_button)
    page.add(
        titlebar
    )
    page.update()

flet.app(target=build)

设置是否有关闭按钮

我们知道HeaderBar初始化时有个has_close的属性,如果需要在后面设置是否有关闭按钮时,就可以调用has_close属性进行设置

import flet
import fleter


def build(page: flet.Page):
    titlebar = fleter.HeaderBar(page)
    titlebar.close_button = False  # True保留关闭按钮,False不保留关闭按钮
    page.add(
        titlebar
    )
    page.update()

flet.app(target=build)

NoteBook

用于快速制作选项卡。

常规

import flet
import fleter

def main(page: flet.Page):
    notebook = fleter.NoteBook()
    for item in range(10):
        notebook.add(f"Item {item+1}", flet.Text(value=f"I`m item {item + 1}"))
    page.add(
        notebook
    )
    page.update()

flet.app(target=main)

SwichThemeButton

用于快速切换窗口主题的图标按钮组件。

常规

import flet
import fleter

def main(page: flet.Page):
    swich_theme_button = fleter.SwichThemeButton(page)
    page.add(
        swich_theme_button
    )
    page.update()

flet.app(target=main)

无系统主题选项

import flet
import fleter

def main(page: flet.Page):
    swich_theme_button = fleter.SwichThemeButton(page, has_system=False)
    page.add(
        swich_theme_button
    )
    page.update()

flet.app(target=main)

SphinBox

进步器,用于调整整数或浮点数的数值

import flet
import fleter

def main(page: flet.Page):
    page.add(
        fleter.SphinBox()
    )
    page.update()

flet.app(target=main)

浮点数步进器

import flet
import fleter

def main(page: flet.Page):
    page.add(
        fleter.SphinBox(plus=0.1, minus=0.1)
    )
    page.update()

flet.app(target=main)

最大值与最小值

设置步进器可设置的最大值。

import flet
import fleter

def main(page: flet.Page):
    page.add(
        fleter.SphinBox(max_value=5, min_value=-5)
    )
    page.update()

flet.app(target=main)

Time

使用threading库做出来的记时工具。

import flet
import fleter

def main(page: flet.Page):

    def tick(id, tick_time):
        print(f"{id} {tick_time}")

    time = fleter.Time(tick)
    time.start("time", 10)

    page.update()

flet.app(target=main)
