更改QToolBox的某些选项卡的颜色

时间：2018-06-13 15:21:59

标签： qt pyqt5

我想更改QToolBox的某个标签页（页面）的颜色

enter image description here

我想出了如何像这样（StyleSheet）单独更改每个标签的样式：

        QToolBox::tab {
            background: blue;
            border-radius: 5px;
            color: black;
        }

另外，我知道如何更改每个QWidget的调色板（通过setPalette或StyleSheet，如建议的here）。但它只改变某些标签的主体，它不会影响标签的头部。

所以，我无法弄清楚如何更改某个标签。可能有一些paintEvent()或tabletEvent()，但我仍然不了解如何使用它。

试一试：

import sys
from PyQt5.QtWidgets import *

class Window(QWidget):
    def __init__(self):
        QWidget.__init__(self)

        layout = QGridLayout()
        self.setLayout(layout)

        toolbox = QToolBox()
        layout.addWidget(toolbox, 0, 0)

        label1 = QLabel("Example content, Tab 1")
        toolbox.addItem(label1, "Tab 1")

        label2 = QLabel("Tab 2 ....", styleSheet="""
            background-color: red;
            border-top-right-radius: 4px;
            color:white;
        """)
        toolbox.addItem(label2, "Tab 2")

        label3 = QLabel("""
        <b>QToolBox::tab:last </b>{<br>
            background: #f95300;<br>
            border-radius: 5px;<br>
            color: black;
        }
        """)

        toolbox.addItem(label3, "Tab 3")


# StyleSheet
StyleSheet = """

Window{background: #b8cdee;}

QToolBox::tab {
    background: #009deb;
    border-radius: 5px;

    background: #4ade00;
    border-radius: 5px;
    color: black;

QToolBox::tab:last {
    background: #f95300;
    border-radius: 5px;
    color: black;
}

QToolBox::tab:selected { /* italicize selected tabs */
    font: italic;
    color: white;
}
"""

app = QApplication(sys.argv)
app.setStyleSheet(StyleSheet) 
screen = Window()
screen.show()
sys.exit(app.exec_())

我通过创建工具箱小部件解决了这个问题。我没有玩调色板，但我认为你可以轻松改变它。此外，还可以同时扩展多个页面。

class MyToolBoxWidget(QtWidgets.QWidget):
    def __init__(self, parent=None):
        QtWidgets.QWidget.__init__(self, parent=parent)
        self.vertical_layout = QtWidgets.QVBoxLayout(self)
        self.vertical_layout.setContentsMargins(0, 0, 0, 0)
        self.vertical_layout.setSpacing(0)
        self.pages = []
        self.tabs = []

        self._first_v_spacerItem = QtWidgets.QSpacerItem(20, 40, QtWidgets.QSizePolicy.Minimum, QtWidgets.QSizePolicy.Expanding)

    def addItem(self, page, name, color=None):
        tab_button = QtWidgets.QPushButton(name)
        font = QtGui.QFont()
        font.setBold(True)
        tab_button.setFont(font)
        page.setSizePolicy(QtWidgets.QSizePolicy(QtWidgets.QSizePolicy.Expanding, QtWidgets.QSizePolicy.Expanding))
        page.hide()
        self.pages.append(page)
        self.tabs.append(tab_button)
        self.vertical_layout.addWidget(tab_button)
        self.vertical_layout.addWidget(page)
        tab_button.clicked.connect(self._button_clicked)

        if color:
            self.setColor( (len(self.pages) - 1), color  )

    def setColor(self, index, color):
        palette = self.get_palette(color)
        self.pages[index].setPalette(palette)
        self.tabs[index].setPalette(palette)
        self.pages[index].setAutoFillBackground(True)

    def check_if_all_pages_are_hidden(self):
        areHidden = True
        for page in self.pages:
            if not page.isHidden():
                areHidden = False
                break
        if areHidden:
            self.vertical_layout.addItem(self._first_v_spacerItem)
        else:
            self.vertical_layout.removeItem(self._first_v_spacerItem)

    def _button_clicked(self):
        i = self.tabs.index(self.sender())
        if self.pages[i].isHidden():
            self.pages[i].show()
        else:
            self.pages[i].hide()
        self.check_if_all_pages_are_hidden()

    def get_palette(self, color):
        palette = QtGui.QPalette()

        brush.setStyle(QtCore.Qt.SolidPattern)
        palette.setBrush(QtGui.QPalette.Disabled, QtGui.QPalette.ToolTipText, brush)

        return palette

主应用程序中的用法：

my_tool_box = MyToolBoxWidget()

page1 = QtWidgets.QWidget()
my_tool_box.addItem(page=page1, name="Tab 1", color="#4ade00")

page2 = QtWidgets.QWidget()
my_tool_box.addItem(page=page2, name="Tab 2", color="#009deb")

page3 = QtWidgets.QWidget()
my_tool_box.addItem(page=page3, name="Tab 3", color="#f95300")

# Add spacer in the end
my_tool_box.check_if_all_pages_are_hidden()

将其翻译成python，我得出以下解决方案：

try:
    print(countries[user_input])
except KeyError: # If the user input wasn't found in the dictionary
    print("Invalid Country!")
