将 PyQt 对话框移动到选项卡

Question

我有一个 GUI，我正在尝试制作一个具有不同功能的选项卡式 window 界面；加载数据、清理数据、处理数据等

我有一个按钮，可以从列表中选择一个类别。我不知道如何将其移至我的选项卡。因此，当我更改选项卡时，对话框始终位于顶部，而我希望它位于第一个选项卡上。

我可以像其他按钮一样移动 "Select category" 按钮并在上方添加标签以显示选择，但不知道如何移动带有 addRow 布局的对话框。这可能吗？

谢谢。

下面的代码；

from __future__ import division, print_function
import sys
from PyQt4 import QtGui, QtCore


class tester(QtGui.QWidget):

    def __init__(self):
        # create GUI
        QtGui.QMainWindow.__init__(self)
        self.setWindowTitle('Data tool')

        # window dimensions
        self.resize(300, 75)
        form = QtGui.QFormLayout()

        # tabbing on
        tab_widget = QtGui.QTabWidget()
        tab1 = QtGui.QWidget()
        tab2 = QtGui.QWidget()
        self.p1_vertical = QtGui.QVBoxLayout(tab1)
        self.p2_vertical = QtGui.QVBoxLayout(tab2)
        tab_widget.addTab(tab1, "Data selection")
        tab_widget.addTab(tab2, "Tools")

        # selected dir label
        self.lbl_dir = QtGui.QLabel('Data directory not selected')
        self.p1_vertical.addWidget(self.lbl_dir)

        # button label for datadir
        btn_dir = QtGui.QPushButton('Browse...', self)
        self.p1_vertical.addWidget(btn_dir)
        self.connect(btn_dir, QtCore.SIGNAL('clicked()'), self.get_dirname)

        # this is the bit i want to be in the tab
        # get category input
        self.btn_cat = QtGui.QPushButton("Select category")
        self.btn_cat.clicked.connect(self.getcat)
        self.le3 = QtGui.QLineEdit()
        form.addRow(self.btn_cat, self.le3)
        self.le3.setReadOnly(True)

        # label for status of run
        self.lblrun = QtGui.QLabel('Run')
        self.p2_vertical.addWidget(self.lblrun)

        # button for run
        btn_run = QtGui.QPushButton('Run', self)
        self.p2_vertical.addWidget(btn_run)
        self.connect(btn_run, QtCore.SIGNAL('clicked()'), self.run)

        # vertical layout for widgets
        self.vbox = QtGui.QVBoxLayout()
        self.vbox.addLayout(form)
        self.vbox.addWidget(tab_widget)
        self.setLayout(self.vbox)

    def getcat(self):
        cats = ['option 1', 'option 2'] 
        category, ok = QtGui.QInputDialog.getItem(self, "select category", 
            "Option", cats, 0, False)
        if ok:
            self.le3.setText(category)
            self.category = category

    def get_dirname(self):
        print('yes')

    def run(self):
        print('yes')

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    gui = tester()
    gui.show()
    app.exec_()

看起来像这样；

您必须在 tab1 的布局中设置 QFormLayout 以消除以下内容：

self.p1_vertical.addLayout(form)

并添加：

self.vbox.addLayout(form)

尽管为了更好的组织，我更愿意创建新的类:

from __future__ import division, print_function
import sys
from PyQt4 import QtGui, QtCore

class DataSelectionWidget(QtGui.QWidget):
    def __init__(self, parent=None):
        super(DataSelectionWidget, self).__init__(parent)

        self.btn_cat = QtGui.QPushButton("Select category")
        self.btn_cat.clicked.connect(self.getcat)
        self.le3 = QtGui.QLineEdit(readOnly=True)
        flay = QtGui.QFormLayout(self)
        flay.addRow(self.btn_cat, self.le3)

        # selected dir label
        self.lbl_dir = QtGui.QLabel('Data directory not selected')
        flay.addRow(self.lbl_dir)

        # button label for datadir
        btn_dir = QtGui.QPushButton('Browse...', self)
        flay.addRow(btn_dir)
        btn_dir.clicked.connect(self.get_dirname)

    @QtCore.pyqtSlot()
    def getcat(self):
        cats = ['option 1', 'option 2'] 
        category, ok = QtGui.QInputDialog.getItem(self, "select category", 
            "Option", cats, 0, False)
        if ok:
            self.le3.setText(category)
            self.category = category        

    @QtCore.pyqtSlot()
    def get_dirname(self):
        print('yes')


class ToolsWidget(QtGui.QWidget):
    def __init__(self, parent=None):
        super(ToolsWidget, self).__init__(parent)
        lay = QtGui.QVBoxLayout(self)

        self.lblrun = QtGui.QLabel('Run')
        lay.addWidget(self.lblrun)

        # button for run
        btn_run = QtGui.QPushButton('Run', self)
        lay.addWidget(btn_run)
        btn_run.clicked.connect(self.run)

    @QtCore.pyqtSlot()
    def run(self):
        print('yes')


class Tester(QtGui.QWidget):
    def __init__(self, parent=None):
        # create GUI
        super(Tester, self).__init__(parent)
        self.setWindowTitle('Data tool')
        # window dimensions
        self.resize(300, 75)
        tab1 = DataSelectionWidget()
        tab2 = ToolsWidget()
        # tabbing on
        tab_widget = QtGui.QTabWidget()
        tab_widget.addTab(tab1, "Data selection")
        tab_widget.addTab(tab2, "Tools")

        lay = QtGui.QVBoxLayout(self)
        lay.addWidget(tab_widgetn)


if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    gui = Tester()
    gui.show()
    sys.exit(app.exec_())
