Mutual resizing of widgets


Mutual resizing of widgets

With these it helps To get that behavior you can use a QHBoxLayout by embedding a rotated button in the middle of the side widgets. You must change the left widget's size policy so that it does not expand.
To implement the rotated button you must override the paintEvent method, in addition to modifying the size policy so that it expands vertically and not horizontally.
code :
class ShrinkExpandButton(QPushButton):
    def __init__(self, *args, **kwargs):
        QPushButton.__init__(self, *args, **kwargs)
        self.setSizePolicy(QSizePolicy.Maximum, QSizePolicy.Expanding)
        self.setFixedWidth(2*self.fontMetrics().height())

    def paintEvent(self, event):
        painter = QStylePainter(self)
        painter.rotate(-90)
        painter.translate(-self.height(), 0)
        option = QStyleOptionButton()
        self.initStyleOption(option)
        size = option.rect.size()
        size.transpose()
        option.rect.setSize(size)
        painter.drawControl(QStyle.CE_PushButton, option)


class ShrinkExpandWidget(QWidget):
    def __init__(self, leftWidget, rightWiget, text, parent=None):
        QWidget.__init__(self, parent)
        button = ShrinkExpandButton(text, self)

        self.setLayout(QHBoxLayout())
        self.layout().setSpacing(0)
        self.layout().addWidget(leftWidget)
        self.layout().addWidget(button)
        self.layout().addWidget(rightWiget)
        leftWidget.setSizePolicy(QSizePolicy.Maximum, QSizePolicy.Expanding)
        button.clicked.connect(lambda: leftWidget.setVisible(not leftWidget.isVisible()))
if __name__ == '__main__':
    import sys
    app = QApplication(sys.argv)
    listWidget = QListWidget()
    for i in range(20):
        listWidget.addItem("{}".format(i))

    tableWidget = QTableWidget()
    tableWidget.setColumnCount(10)
    tableWidget.setRowCount(20)
    for i in range(tableWidget.rowCount()):
        for j in range(tableWidget.columnCount()):
            tableWidget.setItem(i, j, QTableWidgetItem("({}, {})".format(i, j)))
    listWidget.setFixedWidth(240)
    w = ShrinkExpandWidget(listWidget, tableWidget, "Shrink - Expand")
    w.resize(720, 480)
    w.show()
    sys.exit(app.exec_())

fixed the issue. Will look into that further I am working on a project in python using gtk and in it the is a gtk notebook on top of a vte console. I am having trouble getting it to be resizable by the user (i.e. I want the user to be able to drag the border of the 2 up and down and resize both accordingly). Could anyone point me in the right direction on how to do this? , Try this:
code :
vpan = gtk.VPaned()
vpan.show()
vpan.pack1(box1, shrink=False)
vpan.pack2(box2, shrink=False)

wish helps you How do I change the size of wxPython widget after its creation? I am trying to dynamically change the width of a ComboBoxCtrl widget based on the elements in the popup. For the sake of simplicity lets say we create a button and try to resize it: , The SetMinSize command does the trick.
code :
btn = wx.Button(self, wx.ID_ANY, 'Start', size=(25,-1))
btn.SetMinSize(wx.Size(25,25))

self.Layout()

fixed the issue. Will look into that further If the rows have a fixed height, all you need to do to is add an expandable space to the end of the container's layout, so that the rows are all pushed upwards:
code :
container = QtWidgets.QWidget()
list_layout = QtWidgets.QVBoxLayout()
container.setLayout(list_layout)
...
for x in range(10):
    ...
    list_layout.addWidget(separator)
list_layout.addStretch()

I wish did fix the issue. You'll need to use a QLayout of some kind.
You can do this very easily in Designer. Just right click the form and choose Layout and either Lay Out Horizontally or Lay Out Vertically - you'll need other widgets on the form to see the difference between the two. You'll see the QLayout added in the Object Inspector and you'll be able to adjust its properties like you can with your widgets.
