Layout

Each component can use layout methods to arrange itself using, for instance, widget.box(), which is similar to how things work in tkinter. Comparing to other solutions used in Qt or other UI frameworks, we believe this approach is more simple and user-friendly.

每个组件都可以使用布局方法来布局自己，例如widget.box()，类似于tkinter，我觉得这样更简洁易用点。

Box Layout

It can be considered a simplified version of tkinter.pack—with side, expand, padx, pady, ipadx, and ipady attributes. Each container can only choose one layout direction. For example, you cannot use both widget.box(side="left") and widget.box(side="right") simultaneously.

可以被称为tkinter.pack的简易版，包含side、expand、padx、pady、ipadx和ipady属性。 每个容器只能选择一种布局方向，例如，不能同时使用widget.box(side="left")和widget.box(side="right")。

Vertical layout / 垂直布局

The default layout is vertical.

默认为垂直方向布局。

widget.box()

Horizontal layout / 水平布局

widget.box(side="left")
widget2.box(side="right")

Layout with padding

widget.box(padx=10, pady=5, ipadx=2, ipady=2)

Expanding widgets

widget.box(expand=True)

Grid Layout

Grid layout allows you to arrange widgets in a grid pattern.

widget.grid(row=0, column=0)
widget2.grid(row=0, column=1)
widget3.grid(row=1, column=0, columnspan=2)

Fixed Layout

Fixed layout allows you to position widgets at specific coordinates.

widget.fixed(x=10, y=10, width=100, height=30)

How it Works / 原理

Basic Principles / 基础原理

• Uses glfw as window management library
• Uses pyopengl as rendering backend
• Uses skia-python for 2D graphics rendering
• Event-driven architecture for handling user interactions

使用glfw作为窗口管理库，使用pyopengl作为渲染后端，使用skia-python作为2D图形渲染库，采用事件驱动架构处理用户交互。

Themes

Suzaku supports multiple themes, including:

• Light theme
• Dark theme
• Special themes (SV Light, SV Dark)

Applying Themes

from suzaku.styles.theme import SkTheme

# Load a theme
theme = SkTheme.load("path/to/theme.json")

# Apply theme to window
window.apply_theme(theme)

Events

Basic Event Handling

# Bind a function to a widget event
widget.bind("click", lambda evt: print("Clicked!"))

# Bind to keyboard events
window.bind("key_press", lambda evt: print(f"Key pressed: {evt['key']}"))

# Bind to mouse events
widget.bind("mouse_enter", lambda evt: print("Mouse entered!"))
widget.bind("mouse_leave", lambda evt: print("Mouse left!"))

Available Events

• click: Mouse click
• double_click: Double click
• mouse_enter: Mouse enters widget
• mouse_leave: Mouse leaves widget
• mouse_press: Mouse button pressed
• mouse_release: Mouse button released
• key_press: Key pressed
• key_release: Key released
• focus_gain: Widget gains focus
• focus_loss: Widget loses focus
• resize: Widget resized
• configure: Widget configured
• update: Widget updated
• scroll: Mouse wheel scrolled

Examples

Basic Application

from suzaku import *

app = SkApp()

window = SkWindow(title="My App", size=(400, 300))

# Create a button
button = SkButton(window, text="Click Me")
button.box(padx=10, pady=10)
button.bind("click", lambda evt: print("Button clicked!"))

# Create a label
label = SkLabel(window, text="Hello, Suzaku!")
label.box(padx=10, pady=5)

window.update_layout()
app.run()

Naming / 取名

Suzaku is one of the four mythical beasts in ancient China, representing the south and the element of fire. It symbolizes vitality, growth, and transformation.

suzaku是中国古代的四大神兽之一，代表南方和火元素，象征着生命力、成长和变革。
