### Setup UI for Frameless Window with Qt Designer

Source: https://pyqt-frameless-window.readthedocs.io/en/latest/usage.html

This code defines the UI structure for a PyQt window, intended for use with a frameless window implementation. It includes layout setup and widget definitions, with a specific margin to accommodate a title bar.

```python
class Ui_Form(object):
    def setupUi(self, Form):
        Form.resize(400, 423)
        self.verticalLayout_2 = QVBoxLayout(Form)
        self.verticalLayout_2.setContentsMargins(-1, 32, -1, -1)
        self.frame_2 = QFrame(Form)
        self.verticalLayout = QVBoxLayout(self.frame_2)
        self.horizontalLayout = QHBoxLayout()
        self.pushButton = QPushButton(self.frame_2)
        self.horizontalLayout.addWidget(self.pushButton)
        self.lineEdit = QLineEdit(self.frame_2)
        self.horizontalLayout.addWidget(self.lineEdit)
        self.verticalLayout.addLayout(self.horizontalLayout)
        self.horizontalLayout_2 = QHBoxLayout()
        self.pushButton_2 = QPushButton(self.frame_2)
        self.horizontalLayout_2.addWidget(self.pushButton_2)
        self.lineEdit_2 = QLineEdit(self.frame_2)
        self.horizontalLayout_2.addWidget(self.lineEdit_2)
        self.verticalLayout.addLayout(self.horizontalLayout_2)
        self.verticalLayout_2.addWidget(self.frame_2)
        self.frame = QFrame(Form)
        self.horizontalLayout_3 = QHBoxLayout(self.frame)
        self.tableView = QTableView(self.frame)
        self.horizontalLayout_3.addWidget(self.tableView)
        self.verticalLayout_2.addWidget(self.frame)

        self.retranslateUi(Form)

    def retranslateUi(self, Form):
        _translate = QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "Form"))
        self.pushButton.setText(_translate("Form", "选择文件"))
        self.pushButton_2.setText(_translate("Form", "创建路径"))
```

### Inherit FramelessWindow for Custom Native Event Handling

Source: https://pyqt-frameless-window.readthedocs.io/en/latest/snap-layout.html

Example of inheriting FramelessWindow to rewrite the nativeEvent method for custom Windows message handling. This is useful for customizing window behavior like snap layouts and title bar interactions.

```python
import sys

if sys.platform != "win32":
    from qframelesswindow import FramelessWindow
else:
    from ctypes.wintypes import MSG

    import win32con
    from PyQt5.QtCore import QPoint, QEvent, Qt
    from PyQt5.QtGui import QCursor, QMouseEvent
    from PyQt5.QtWidgets import QApplication

    from qframelesswindow import FramelessWindow as Window
    from qframelesswindow.titlebar.title_bar_buttons import TitleBarButtonState


    class FramelessWindow(Window):
        """ Frameless window """

        def nativeEvent(self, eventType, message):
            """ Handle the Windows message """

```

--------------------------------

### Implement a minimal frameless window

Source: https://pyqt-frameless-window.readthedocs.io/en/latest/usage.html

Inherit from FramelessWindow to create a basic frameless application window.

```python
import sys

from PyQt5.QtWidgets import QApplication
from qframelesswindow import FramelessWindow


class Window(FramelessWindow):

    def __init__(self, parent=None):
        super().__init__(parent=parent)
        self.setWindowTitle("PyQt-Frameless-Window")
        self.titleBar.raise_()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    demo = Window()
    demo.show()
    sys.exit(app.exec_())
```

--------------------------------

### Use StandardTitleBar with icon and title

Source: https://pyqt-frameless-window.readthedocs.io/en/latest/usage.html

Replace the default title bar with StandardTitleBar to include window icons and titles.

```python
from qframelesswindow import FramelessWindow, StandardTitleBar


class Window(FramelessWindow):

    def __init__(self, parent=None):
        super().__init__(parent=parent)
        # replace the default title bar with StandardTitleBar
        self.setTitleBar(StandardTitleBar(self))

        self.setWindowIcon(QIcon("screenshot/logo.png"))
        self.setWindowTitle("PyQt-Frameless-Window")

        # don't forget to put the title bar at the top
        self.titleBar.raise_()
```

--------------------------------

### Integrate UI with FramelessWindow Class

Source: https://pyqt-frameless-window.readthedocs.io/en/latest/usage.html

This Python code demonstrates how to inherit from both a generated UI class (Ui_Form) and a custom FramelessWindow class to create a functional frameless window. Ensure the FramelessWindow class is defined elsewhere.

```python
class Window(FramelessWindow, Ui_Form):

    def __init__(self, parent=None):
        super().__init__(parent)
        self.setupUi(self)

```

--------------------------------

### Create an Acrylic Window

Source: https://pyqt-frameless-window.readthedocs.io/en/latest/window-effect.html

Use the AcrylicWindow class to create a window with an acrylic blur effect. Ensure the title bar is raised if customizing effects.

```python
from qframelesswindow import AcrylicWindow


class Window(AcrylicWindow):

    def __init__(self, parent=None):
        super().__init__(parent=parent)
        self.setWindowTitle("Acrylic Window")
        self.titleBar.raise_()

        # customize acrylic effect
        # self.windowEffect.setAcrylicEffect(self.winId(), "106EBE99")

        # you can also enable mica effect on Win11
        # self.windowEffect.setMicaEffect(self.winId(), False)

```

--------------------------------

### Enable Snap Layout in Frameless Window

Source: https://pyqt-frameless-window.readthedocs.io/en/latest/snap-layout.html

Override the nativeEvent method to handle Windows messages for snap layout and custom title bar button interactions. This code should replace the existing nativeEvent in qframelesswindow/windows/__init__.py.

```python
from ..titlebar.title_bar_buttons import TitleBarButtonState

def nativeEvent(self, eventType, message):
    """ Handle the Windows message """
    msg = MSG.from_address(message.__int__())
    if not msg.hWnd:
        return super().nativeEvent(eventType, message)

    if msg.message == win32con.WM_NCHITTEST and self._isResizeEnabled:
        pos = QCursor.pos()
        xPos = pos.x() - self.x()
        yPos = pos.y() - self.y()
        w, h = self.width(), self.height()
        lx = xPos < self.BORDER_WIDTH
        rx = xPos > w - self.BORDER_WIDTH
        ty = yPos < self.BORDER_WIDTH
        by = yPos > h - self.BORDER_WIDTH
        if lx and ty:
            return True, win32con.HTTOPLEFT
        elif rx and by:
            return True, win32con.HTBOTTOMRIGHT
        elif rx and ty:
            return True, win32con.HTTOPRIGHT
        elif lx and by:
            return True, win32con.HTBOTTOMLEFT
        elif ty:
            return True, win32con.HTTOP
        elif by:
            return True, win32con.HTBOTTOM
        elif lx:
            return True, win32con.HTLEFT
        elif rx:
            return True, win32con.HTRIGHT

    #--------------------------------------- ADDED CODE --------------------------------------#
        elif self.titleBar.childAt(pos-self.geometry().topLeft()) is self.titleBar.maxBtn:
            self.titleBar.maxBtn.setState(TitleBarButtonState.HOVER)
            return True, win32con.HTMAXBUTTON
    elif msg.message in [0x2A2, win32con.WM_MOUSELEAVE]:
        self.titleBar.maxBtn.setState(TitleBarButtonState.NORMAL)
    elif msg.message in [win32con.WM_NCLBUTTONDOWN, win32con.WM_NCLBUTTONDBLCLK]:
        if self.titleBar.childAt(QCursor.pos()-self.geometry().topLeft()) is self.titleBar.maxBtn:
            QApplication.sendEvent(self.titleBar.maxBtn, QMouseEvent(
                QEvent.MouseButtonPress, QPoint(), Qt.LeftButton, Qt.LeftButton, Qt.NoModifier))
            return True, 0
    elif msg.message in [win32con.WM_NCLBUTTONUP, win32con.WM_NCRBUTTONUP]:
        if self.titleBar.childAt(QCursor.pos()-self.geometry().topLeft()) is self.titleBar.maxBtn:
            QApplication.sendEvent(self.titleBar.maxBtn, QMouseEvent(
                QEvent.MouseButtonRelease, QPoint(), Qt.LeftButton, Qt.LeftButton, Qt.NoModifier))
    #------------------------------------------------------------------------------------------#

    elif msg.message == win32con.WM_NCCALCSIZE:
        if msg.wParam:
            rect = cast(msg.lParam, LPNCCALCSIZE_PARAMS).contents.rgrc[0]
        else:
            rect = cast(msg.lParam, LPRECT).contents

        isMax = win_utils.isMaximized(msg.hWnd)
        isFull = win_utils.isFullScreen(msg.hWnd)

        # adjust the size of client rect
        if isMax and not isFull:
            thickness = win_utils.getResizeBorderThickness(msg.hWnd)
            rect.top += thickness
            rect.left += thickness
            rect.right -= thickness
            rect.bottom -= thickness

        # handle the situation that an auto-hide taskbar is enabled
        if (isMax or isFull) and Taskbar.isAutoHide():
            position = Taskbar.getPosition(msg.hWnd)
            if position == Taskbar.LEFT:
                rect.top += Taskbar.AUTO_HIDE_THICKNESS
            elif position == Taskbar.BOTTOM:
                rect.bottom -= Taskbar.AUTO_HIDE_THICKNESS
            elif position == Taskbar.LEFT:

        result = 0 if not msg.wParam else win32con.WVR_REDRAW
        return True, result

    return super().nativeEvent(eventType, message)
```

--------------------------------

### Customize the title bar appearance

Source: https://pyqt-frameless-window.readthedocs.io/en/latest/usage.html

Extend TitleBar to modify button colors or apply custom QSS styles to title bar components.

```python
from qframelesswindow import FramelessWindow, TitleBar


class CustomTitleBar(TitleBar):
    """ Custom title bar """

    def __init__(self, parent):
        super().__init__(parent)

        # customize the style of title bar button
        self.minBtn.setHoverColor(Qt.white)
        self.minBtn.setHoverBackgroundColor(QColor(0, 100, 182))
        self.minBtn.setPressedColor(Qt.white)
        self.minBtn.setPressedBackgroundColor(QColor(54, 57, 65))

        # use qss to customize title bar button
        self.maxBtn.setStyleSheet("""
            TitleBarButton {
                qproperty-normalColor: black;
                qproperty-normalBackgroundColor: transparent;
                qproperty-hoverColor: white;
                qproperty-hoverBackgroundColor: rgb(0, 100, 182);
                qproperty-pressedColor: white;
                qproperty-pressedBackgroundColor: rgb(54, 57, 65);
            }
        """)


class Window(FramelessWindow):

    def __init__(self, parent=None):
        super().__init__(parent=parent)
        # change the default title
        self.setTitleBar(CustomTitleBar(self))
```

--------------------------------

### Toggle Acrylic Effect

Source: https://pyqt-frameless-window.readthedocs.io/en/latest/window-effect.html

This method enables or disables the acrylic effect and applies a background color or transparency. It also conditionally adds a shadow effect based on the operating system version.

```python
def setAcrylicEffectEnabled(self, enable: bool):
    """ set acrylic effect enabled """
    self.setStyleSheet(f"background:{'transparent' if enable else '#F2F2F2'}")
    if enable:
        self.windowEffect.setAcrylicEffect(self.winId(), "F2F2F299")
        if QOperatingSystemVersion.current() != QOperatingSystemVersion.Windows10:
            self.windowEffect.addShadowEffect(self.winId())
    else:
        self.windowEffect.addShadowEffect(self.winId())
        self.windowEffect.removeBackgroundEffect(self.winId())

```

--------------------------------

### Intercepting Native Windows Events

Source: https://pyqt-frameless-window.readthedocs.io/en/latest/snap-layout.html

Overrides nativeEvent to handle window hit testing and mouse interactions for custom title bar buttons. Requires win32con and PyQt5/6 event handling.

```python
msg = MSG.from_address(message.__int__())
            if not msg.hWnd:
                return super().nativeEvent(eventType, message)

            if msg.message == win32con.WM_NCHITTEST and self._isResizeEnabled:
                if self._isHoverMaxBtn():
                    self.titleBar.maxBtn.setState(TitleBarButtonState.HOVER)
                    return True, win32con.HTMAXBUTTON

            elif msg.message in [0x2A2, win32con.WM_MOUSELEAVE]:
                self.titleBar.maxBtn.setState(TitleBarButtonState.NORMAL)
            elif msg.message in [win32con.WM_NCLBUTTONDOWN, win32con.WM_NCLBUTTONDBLCLK] and self._isHoverMaxBtn():
                e = QMouseEvent(QEvent.MouseButtonPress, QPoint(), Qt.LeftButton, Qt.LeftButton, Qt.NoModifier)
                QApplication.sendEvent(self.titleBar.maxBtn, e)
                return True, 0
            elif msg.message in [win32con.WM_NCLBUTTONUP, win32con.WM_NCRBUTTONUP] and self._isHoverMaxBtn():
                e = QMouseEvent(QEvent.MouseButtonRelease, QPoint(), Qt.LeftButton, Qt.LeftButton, Qt.NoModifier)
                QApplication.sendEvent(self.titleBar.maxBtn, e)

            return super().nativeEvent(eventType, message)

        def _isHoverMaxBtn(self):
            pos = QCursor.pos() - self.geometry().topLeft() - self.titleBar.pos()
            return self.titleBar.childAt(pos) is self.titleBar.maxBtn
```
