PyQt5 QMainWindow,QDockWidget,适合屏幕尺寸自动调整
PyQt5 QMainWindow, QDockWidget, fitting autosize with screensize
我创建了一个 QMainWindow
和 4 个 dockable widgets
菜单栏。第一个 dockwidget 内容 multipletabs
,第二个是 Qpainter widget
,第三个是 Matlabplot
,第四个是 pdf report
。
当我 运行 代码如下所示时。
我要像下面这样
我想在任何屏幕 运行 出现时自动将屏幕分成四个小部件,并且我希望有选项卡可以根据其内容调整大小。
或者你有什么更好的想法拥有这样的小部件,欢迎你来。
代码更新
调整 Qdockwidget 的大小使这个 post 向前。似乎 Qt Qdockwidget resize 很久以前就已经是一个问题了。我发现很难用 4 个 Qdockwidget 对我的 Qmainwindow 进行编程,dock 会根据其内容(换句话说,子窗口小部件)适应并调整大小。根据 Qt 文档,Qdockwidget 会调整大小并尊重子 Widget 的大小。直接进入问题,我的主窗口有 4 个 qdockwidgets,我想让它们根据内容调整大小。
到目前为止我已经尝试过和使用过的东西。
我使用了以下大小函数。
self.sizeHint, self.minimumSize(), self.maximumSize() and self.setFixedSize(self.sizeHint()).
我可以使用以下代码修复第一个 Qdockwidget 中内容的大小。
self.setFixedSize(self.sizeHint())
以上代码写在子widgets中Class widgets
但这还不够,尽管 运行 和效果需要以下代码。
self.first.setMinimumSize(self.first.sizeHint())
self.grid.setMinimumSize(self.grid.sizeHint())
self.third.setMinimumSize(self.third.sizeHint())
self.adjustSize()
self.first.setMinimumSize(self.first.minimumSizeHint())
self.grid.setMinimumSize(self.grid.minimumSizeHint())
self.third.setMinimumSize(self.third.minimumSizeHint())
注意到我的停靠窗口仍然没有根据子窗口小部件调整大小。 Dockwidget 扩展和增加。有人会问,Qdockwidgets可以通过resizeDocks()
来排列和控制。此代码行已使用并尝试过,但仍未获得所需的行为。
我一直在四处寻找,可以找到一些相关的问题。
C++ 以编程方式调整停靠 Qt QDockWidget 的大小?
强制 QDockWidget 在调整大小时表现得像中央小部件
这些问题没有解决我的问题。
我的代码启动可视化

2- 软件的第一个 运行 需要和想要的显示。
3- 当用户在 tabwidget 之间的 tab 想要调整其内容时,如下图所示。

如果有任何帮助,我将不胜感激。
如果浮动 windows 对您的工具来说不是必需的,那么您可以尝试删除 QDockWidget
并使用一系列 QSplitter
。通过这种方式,您可以拥有漂亮的框布局,同时让选项卡可以水平和垂直调整大小,并且在整个工具调整大小时仍然可以正确调整大小。
我的示例在 PySide2
中,但您可能需要对 PyQt5
做非常小的调整(可能只是导入名称):
from PySide2 import QtCore
from PySide2 import QtGui
from PySide2 import QtWidgets
class SubWindow(QtWidgets.QWidget):
def __init__(self, label, parent=None):
super(SubWindow, self).__init__(parent)
self.label = QtWidgets.QLabel(label, parent=self)
self.label.setAlignment(QtCore.Qt.AlignCenter)
self.label.setStyleSheet("QLabel {font-size:40px;}")
self.main_layout = QtWidgets.QVBoxLayout()
self.main_layout.addWidget(self.label)
self.setLayout(self.main_layout)
class MainWindow(QtWidgets.QWidget):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.sub_win_1 = SubWindow("1", parent=self)
self.sub_win_2 = SubWindow("2", parent=self)
self.sub_win_3 = SubWindow("3", parent=self)
self.sub_win_4 = SubWindow("4", parent=self)
self.sub_splitter_1 = QtWidgets.QSplitter(QtCore.Qt.Horizontal, parent=self)
self.sub_splitter_1.addWidget(self.sub_win_1)
self.sub_splitter_1.addWidget(self.sub_win_2)
self.sub_splitter_2 = QtWidgets.QSplitter(QtCore.Qt.Horizontal, parent=self)
self.sub_splitter_2.addWidget(self.sub_win_3)
self.sub_splitter_2.addWidget(self.sub_win_4)
self.splitter = QtWidgets.QSplitter(QtCore.Qt.Vertical, parent=self)
self.splitter.addWidget(self.sub_splitter_1)
self.splitter.addWidget(self.sub_splitter_2)
self.main_layout = QtWidgets.QVBoxLayout()
self.main_layout.addWidget(self.splitter)
self.setLayout(self.main_layout)
self.setWindowTitle("Layout example")
self.resize(500, 500)
inst = MainWindow()
inst.show()
这给你这样的东西:
目前 top/bottom 水平分离器单独运行,但您可以轻松地将它们与事件结合在一起。
希望对您有所帮助!

如果有任何帮助,我将不胜感激。
如果浮动 windows 对您的工具来说不是必需的,那么您可以尝试删除 QDockWidget
并使用一系列 QSplitter
。通过这种方式,您可以拥有漂亮的框布局,同时让选项卡可以水平和垂直调整大小,并且在整个工具调整大小时仍然可以正确调整大小。
我的示例在 PySide2
中,但您可能需要对 PyQt5
做非常小的调整(可能只是导入名称):
from PySide2 import QtCore
from PySide2 import QtGui
from PySide2 import QtWidgets
class SubWindow(QtWidgets.QWidget):
def __init__(self, label, parent=None):
super(SubWindow, self).__init__(parent)
self.label = QtWidgets.QLabel(label, parent=self)
self.label.setAlignment(QtCore.Qt.AlignCenter)
self.label.setStyleSheet("QLabel {font-size:40px;}")
self.main_layout = QtWidgets.QVBoxLayout()
self.main_layout.addWidget(self.label)
self.setLayout(self.main_layout)
class MainWindow(QtWidgets.QWidget):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.sub_win_1 = SubWindow("1", parent=self)
self.sub_win_2 = SubWindow("2", parent=self)
self.sub_win_3 = SubWindow("3", parent=self)
self.sub_win_4 = SubWindow("4", parent=self)
self.sub_splitter_1 = QtWidgets.QSplitter(QtCore.Qt.Horizontal, parent=self)
self.sub_splitter_1.addWidget(self.sub_win_1)
self.sub_splitter_1.addWidget(self.sub_win_2)
self.sub_splitter_2 = QtWidgets.QSplitter(QtCore.Qt.Horizontal, parent=self)
self.sub_splitter_2.addWidget(self.sub_win_3)
self.sub_splitter_2.addWidget(self.sub_win_4)
self.splitter = QtWidgets.QSplitter(QtCore.Qt.Vertical, parent=self)
self.splitter.addWidget(self.sub_splitter_1)
self.splitter.addWidget(self.sub_splitter_2)
self.main_layout = QtWidgets.QVBoxLayout()
self.main_layout.addWidget(self.splitter)
self.setLayout(self.main_layout)
self.setWindowTitle("Layout example")
self.resize(500, 500)
inst = MainWindow()
inst.show()
这给你这样的东西:
目前 top/bottom 水平分离器单独运行,但您可以轻松地将它们与事件结合在一起。
希望对您有所帮助!
