buttons are generated from sql database. When you run only one application, the widget refreshes itself. By clicking successive buttons, the text in the groupbox changes correctly, while the vbox in the groupbox is only pressed. Code below.

I am currently learning PyQt concepts. Through easy examples, I am trying to play with the tab key to jump from one widget to another.
I manage to disable the focus policy on a PushButton, making it impossible to get the focus on it while pushing Tab. However, with a DialogButton, I do not manage to do so.
I feel managing this policy is possible with every type of widget, but I feel a bit lost with all their specificities.
Here is my current code :
from PyQt5 import QtWidgets, QtCore, QtGui
import sys
class TabWidget(QtWidgets.QDialog): # class to implement dialog box
def __init__(self):
super().__init__()
self.setWindowTitle("Tab Widget App")
tabWidget = QtWidgets.QTabWidget() # creation of the tab widget object
tabWidget.addTab(FirstTab(), "First Tab") # fill with first widget
tabWidget.addTab(SecondTab(), "Second Tab")
tabWidget.addTab(ThirdTab(), "Third Tab")

The involved button is my "buttonbox" of type QDialogButton. I have set the focus policy to NoFocus. But when I launch the script and use the tab key in FourthTab, the focus still goes on OK / Cancel.
Are there some restrictions about this option? Or is there something I am missing?
The focus policy is not propagated to the children.
When you set the focus policy on the button box, its children (the buttons) still have their default policy (which is StrongFocus).
If you want to disable that for all buttons, you need to do it explicitly, for instance:
self.buttonbox.button(self.buttonbox.Ok).setFocusPolicy(QtCore.Qt.NoFocus)
Or, for any button:
for button in self.buttonbox.findChildren(QtWidgets.QAbstractButton):
button.setFocusPolicy(QtCore.Qt.NoFocus)
Note that the keyPressEvent is only received by a parent if none of its children has handled it, so if you're trying to capture the Tab you need to install an event filter on the whole QApplication instead, otherwise it's still possible that some widget will capture and accept it, thus preventing you to receive it.
I want to make new window by double click tabwidget.
and copy tabwidget's (child which is tablewidget) to new window.
and finally, changing item of new window's tablewidget needs to change mainwindow's tablewidget.
would it be possible?
I have seen this, that answer does copy tabwidget to new window
but remove mainwindow tabwidget.
here is I worked so far.
I managed to make new dialog by double click, but other things.. I dont' have any clues. can anyone can help?

If you want to synchronize data between item views, you have to use a common model. Since you're using a QTableWidget (which has an internal, private model, and a higher level item view) you can create a new window using a QTableView instead, and set its model to the source. In that case, you don't need to "copy" row/column/data, you only need to use the source model.
Here's a modified version of your script:
class DetachableTabWidget(QTabWidget):
# ...
#pyqtSlot(int, QPoint)
def detachTab(self, index, point):
print("detachTab")
name = self.tabText(index)
icon = self.tabIcon(index)
if icon.isNull():
icon = self.window().windowIcon()
contentWidget = self.widget(index)
contentWidgetRect = contentWidget.frameGeometry()
tablewidgetA = contentWidget.findChild(QTableWidget)
detachedTab = self.DetachedTab(tablewidgetA.model())
detachedTab.setWindowTitle(name)
detachedTab.setWindowIcon(icon)
detachedTab.setObjectName(name)
detachedTab.setGeometry(contentWidgetRect)
detachedTab.move(point)
detachedTab.exec_()
class DetachedTab(QDialog) :
onCloseSignal = pyqtSignal(QWidget,type(''), QIcon)
def __init__(self, model, parent=None) :
print("DetachedTab")
super().__init__()
layout = QVBoxLayout(self)
table = QTableView()
table.setModel(model)
layout.addWidget(table)
table.show()
With this code you can modify the "child" window table data, and it will always synchronize the source table widget.
I got this code from a topic on Stackoverflow ScrolledPanel inside Panel not sizing. It works well for me. However I want to destroy all children of the scrolled_panel then recreate its new children. So I modify the code like this:
import wx
import wx.lib.scrolledpanel as scrolled
########################################################################
class MyForm(wx.Frame):
#----------------------------------------------------------------------
def __init__(self):
wx.Frame.__init__(self, None, wx.ID_ANY, "Tutorial", size=(200,500))

# Add a panel so it looks the correct on all platforms
self.panel = wx.Panel(self, wx.ID_ANY)
# --------------------
# Scrolled panel stuff
self.scrolled_panel = scrolled.ScrolledPanel(self.panel, -1,
style = wx.TAB_TRAVERSAL|wx.SUNKEN_BORDER, name="panel1")
self.scrolled_panel.SetAutoLayout(1)
self.scrolled_panel.SetupScrolling()
words = "A Quick Brown Insane Fox Jumped Over the Fence and Ziplined to Cover".split()
self.spSizer = wx.BoxSizer(wx.VERTICAL)
for word in words:
text = wx.TextCtrl(self.scrolled_panel, value=word)
self.spSizer.Add(text)
self.scrolled_panel.SetSizer(self.spSizer)
# --------------------
btn = wx.Button(self.panel, label="Add Widget")
btn.Bind(wx.EVT_BUTTON, self.onAdd)
panelSizer = wx.BoxSizer(wx.VERTICAL)
panelSizer.AddSpacer(50)
panelSizer.Add(self.scrolled_panel, 1, wx.EXPAND)
panelSizer.Add(btn)
self.panel.SetSizer(panelSizer)
#----------------------------------------------------------------------
def onAdd(self, event):
""""""
print "in onAdd"
self.n += 1
self.scrolled_panel.DestroyChildren()
for i in range(self.n):
new_text = wx.TextCtrl(self.scrolled_panel, value="New Text %s" % i)
self.spSizer.Add(new_text)
#new_text = wx.TextCtrl(self.scrolled_panel, value="New Text")
#self.spSizer.Add(new_text)
self.scrolled_panel.Layout()
self.scrolled_panel.SetupScrolling()
# Run the program
if __name__ == "__main__":
app = wx.App(False)
frame = MyForm().Show()
app.MainLoop()
Now, even when I create the children more than the panel's size can show, I don't see the scroll bar as the original code. Can any one help me with this? Thanks ahead!!!
I solved this problem by adding testpanel to add scrolledPanel in it. Whennever onAdd() is call, after destroying all of testpanel's children, everything under the testpanel even the sizer have to be re-created and re-setup.
I've tried to do like that without the testpanel, I still could scroll by using my mouse, but didn't see the scrollbar, I don't know why. This is my new code:
