Pyside- Add Widget from another class
Question
I am trying to build a layout using PySide and I have run into a situation where I would like to keep a widget group in a separate class and call it dynamically. I looked at few examples from this site which sort of gives me an idea but still I am not able to resolve this issue on my own. Here is the sample code of the layout I am building and it will be very helpful if someone can help me solve this issue. -Thanks in advance
import PySide2.QtCore as QtCore
import PySide2.QtGui as QtGui
import PySide2.QtWidgets as QtGuiWidgets
class TabDialog(QtGuiWidgets.QDialog):
def __init__(self, parent=None):
super(TabDialog, self).__init__(parent)
argument = "Temp"
calldisplay = display_elements()
tabWidget = QtGuiWidgets.QTabWidget()
tabWidget.addTab(tab1(argument), "tab1")
tabWidget.addTab(tab2(argument), "tab2")
buttonBox = QtGuiWidgets.QDialogButtonBox(
QtGuiWidgets.QDialogButtonBox.Ok | QtGuiWidgets.QDialogButtonBox.Cancel)
buttonBox.accepted.connect(self.accept)
buttonBox.rejected.connect(self.reject)
mainLayout = QtGuiWidgets.QVBoxLayout()
mainLayout.addWidget(tabWidget)
mainLayout.addWidget(buttonBox)
self.setLayout(mainLayout)
self.setWindowTitle("Load All Elements")
self.show()

One of the errors I see is that you point as the first argument of tab1 to calldisplay that I guess is the widget you want to set but you are passing it as an argument to "argument" which is a string, so a first change is to change it .
On the other hand if you are going to use layouts forget about setGeometry() since now the geometry is handled by the QLayouts.
And finally, your display_elements class is not implemented correctly since the rgroup is not added to the widget and for this you must use a layout.
Considering the above, the solution is the following:
import PySide2.QtCore as QtCore
import PySide2.QtGui as QtGui
import PySide2.QtWidgets as QtGuiWidgets
class TabDialog(QtGuiWidgets.QDialog):
def __init__(self, parent=None):
super(TabDialog, self).__init__(parent)
argument = "Temp"
calldisplay = display_elements()
tabWidget = QtGuiWidgets.QTabWidget()
tabWidget.addTab(tab1(calldisplay), "tab1")
tabWidget.addTab(tab2(argument), "tab2")
buttonBox = QtGuiWidgets.QDialogButtonBox(
QtGuiWidgets.QDialogButtonBox.Ok | QtGuiWidgets.QDialogButtonBox.Cancel)
buttonBox.accepted.connect(self.accept)
buttonBox.rejected.connect(self.reject)
mainLayout = QtGuiWidgets.QVBoxLayout()
mainLayout.addWidget(tabWidget)
mainLayout.addWidget(buttonBox)
self.setLayout(mainLayout)
self.setWindowTitle("Load All Elements")
self.show()
class tab1(QtGuiWidgets.QWidget):
def __init__(self, calldisplay, parent=None):
super(tab1, self).__init__(parent)
self.layerfilterGroup = QtGuiWidgets.QLabel("Filter 1")
self.peopleGroup = QtGuiWidgets.QGroupBox("Filter 2")
self.dateGroup = QtGuiWidgets.QGroupBox("Filter 3")
self.loadGroup = QtGuiWidgets.QLabel("Load elements")
self.filterGroup = QtGuiWidgets.QGroupBox("Filters")
self.filterGroup.setGeometry(100, 100, 700, 550)
self.filterLayout = QtGuiWidgets.QVBoxLayout()
for key in range(15):
self.btn = QtGuiWidgets.QCheckBox(str(key))
self.btn.setChecked(True)
self.filterLayout.addWidget(self.btn)
