自带的标题栏样式比较固定，有时候我们想自己设计好看的样式，那么就需要自定义标题栏了。

效果图：
去掉标题栏：
self.setWindowFlags(Qt.CustomizeWindowHint) # 去掉标题栏
自定义标题栏：
标题栏有一个文本标题和三个按钮（最小化，最大化（恢复），关闭）
一、创建文本按钮
titleContent = QLabel("标题内容") titleContent.setSizePolicy(QSizePolicy.Expanding, QSizePolicy.Expanding) titleContent.setFixedHeight(TITLE_HEIGHT) titleContent.setObjectName("TitleContent")
二、创建Button按钮
self.ButtonMin = QPushButton("-") self.ButtonMin.setFixedSize(QSize(BUTTON_WIDTH, BUTTON_HEIGHT)) self.ButtonMin.setObjectName("ButtonMin") self.ButtonMax = QPushButton("口") self.ButtonMax.setFixedSize(QSize(BUTTON_WIDTH, BUTTON_HEIGHT)) self.ButtonMax.setObjectName("ButtonMax") self.ButtonRestore = QPushButton("回") self.ButtonRestore.setFixedSize(QSize(BUTTON_WIDTH, BUTTON_HEIGHT)) self.ButtonRestore.setObjectName("ButtonRestore") self.ButtonRestore.setVisible(False) self.ButtonClose = QPushButton("×") self.ButtonClose.setFixedSize(QSize(BUTTON_WIDTH, BUTTON_HEIGHT)) self.ButtonClose.setObjectName("ButtonClose")
三、将文本和button都放到一个标题栏里面
mylayout = QHBoxLayout()
mylayout.setSpacing(0)
mylayout.setContentsMargins(0, 0, 0, 0)
mylayout.addWidget(titleContent)
mylayout.addWidget(self.ButtonMin)
mylayout.addWidget(self.ButtonMax)
mylayout.addWidget(self.ButtonRestore)
mylayout.addWidget(self.ButtonClose)
self.setLayout(mylayout)
四、设置他们的样式qss
with open("./resource/QSS/title_style1.qss") as f: qss = f.read() self.setStyleSheet(qss)
这些就构成了一个标题栏的类
class TitleWidget(QWidget): def __init__(self): super().__init__() # titleIcon = QPixmap("./resource/img/icon.jpg") # Icon = QLabel() # Icon.setPixmap(titleIcon.scaled(25, 25)) titleContent = QLabel("标题内容") titleContent.setSizePolicy(QSizePolicy.Expanding, QSizePolicy.Expanding) titleContent.setFixedHeight(TITLE_HEIGHT) titleContent.setObjectName("TitleContent") self.ButtonMin = QPushButton("-") self.ButtonMin.setFixedSize(QSize(BUTTON_WIDTH, BUTTON_HEIGHT)) self.ButtonMin.setObjectName("ButtonMin") self.ButtonMax = QPushButton("口") self.ButtonMax.setFixedSize(QSize(BUTTON_WIDTH, BUTTON_HEIGHT)) self.ButtonMax.setObjectName("ButtonMax") self.ButtonRestore = QPushButton("回") self.ButtonRestore.setFixedSize(QSize(BUTTON_WIDTH, BUTTON_HEIGHT)) self.ButtonRestore.setObjectName("ButtonRestore") self.ButtonRestore.setVisible(False) self.ButtonClose = QPushButton("×") self.ButtonClose.setFixedSize(QSize(BUTTON_WIDTH, BUTTON_HEIGHT)) self.ButtonClose.setObjectName("ButtonClose") mylayout = QHBoxLayout() mylayout.setSpacing(0) mylayout.setContentsMargins(0, 0, 0, 0) # mylayout.addWidget(Icon) mylayout.addWidget(titleContent) mylayout.addWidget(self.ButtonMin) mylayout.addWidget(self.ButtonMax) mylayout.addWidget(self.ButtonRestore) mylayout.addWidget(self.ButtonClose) self.setLayout(mylayout) # 使用qss渲染 with open("./resource/QSS/title_style1.qss") as f: qss = f.read() self.setStyleSheet(qss) self.restorePos = None self.restoreSize = None self.startMovePos = None def saveRestoreInfo(self, point, size): self.restorePos = point self.restoreSize = size def getRestoreInfo(self): return self.restorePos, self.restoreSize
标题栏的结构存放在类中，我们需要调用它。
self.title = TitleWidget() # 初始化一个标题栏 self.title.setFixedWidth(self.width()) # 设置标题栏宽度 self.title.setFixedHeight(TITLE_HEIGHT) # 设置标题栏高度
样式已经实现了，那么现在就是为他们赋予功能。将各个Button绑定自己的功能函数
self.title.ButtonMin.clicked.connect(self.ButtonMinSlot)
self.title.ButtonMax.clicked.connect(self.ButtonMaxSlot)
self.title.ButtonRestore.clicked.connect(self.ButtonRestoreSlot)
self.title.ButtonClose.clicked.connect(self.ButtonCloseSlot)
编写功能函数
最小化
# 最小化 def ButtonMinSlot(self): self.showMinimized()
最大化
# 最大化 def ButtonMaxSlot(self): self.title.ButtonMax.setVisible(False) self.title.ButtonRestore.setVisible(True) self.title.saveRestoreInfo(self.pos(), QSize(self.width(), self.height())) desktopRect = QApplication.desktop().availableGeometry() FactRect = QRect(desktopRect.x() - 3, desktopRect.y() - 3, desktopRect.width() + 6, desktopRect.height() + 6) self.setGeometry(FactRect) self.setFixedSize(desktopRect.width() + 6, desktopRect.height() + 6)
恢复
# 恢复大小 def ButtonRestoreSlot(self): # 最大化按钮显示 self.title.ButtonMax.setVisible(True) # 隐藏恢复按钮 self.title.ButtonRestore.setVisible(False) # 获取最大化之前的页面的大小数据 windowPos, windowSize = self.title.getRestoreInfo() self.setGeometry(windowPos.x(), windowPos.y(), windowSize.width(), windowSize.height()) self.setFixedSize(windowSize.width(), windowSize.height())
关闭
# 关闭 def ButtonCloseSlot(self): self.close()
最后，将标题栏添加到界面上
self.ui.horizontalLayout.addWidget(self.title)
