I have reproduced the "Custom Completer Example" from the Qt documentation using PySide
(Python 2.7.3, PySide 1.1.2, Qt 4.8.1).
I have an issue where a win32 exception is thrown on exit (or on Mac OS X a access violation exception).
On the Mac I can see a stack trace and the issue occurs during garbage collection, where references to QObjects are apparently not consistent, such that things go bad.
I can see this crash with the following self-contained script, only if a completer insertion was accepted. I.e. type the first few letters, then accept the completion.
On the other hand, if I have seen the completion list popup, but not accepted the completion, no crash occurs on exit.

I'm trying to display some data from a database in a grid view, similar to how a file manager works. I thought of using a QTableView as the grid view since it did what I wanted out of the box. However, as shown with the below given MRE, even if just a single cell has value, you can still select the other empty cells, how can I prevent this? Basically, I want to make it so that only cells with a value can be selected.
MRE:
from PySide6 import QtWidgets as qtw
from PySide6 import QtGui as qtg
from PySide6 import QtCore as qtc
ROW_COUNT = 5
COL_COUNT = 5
class Model(qtc.QAbstractTableModel):
def __init__(self, *args, **kwargs) -> None:
super().__init__(*args, **kwargs)
self._data = [[None for _ in range(COL_COUNT)] for _ in range(ROW_COUNT)]
def data(self, index: qtc.QModelIndex, role: qtc.Qt.ItemDataRole):
if not index.isValid():
return None
if role == qtc.Qt.ItemDataRole.DisplayRole:
return self._data[index.row()][index.column()]
return None
def setData(self, index: qtc.QModelIndex, value, role: qtc.Qt.ItemDataRole=qtc.Qt.ItemDataRole.DisplayRole):
if not index.isValid():
return False
if role == qtc.Qt.ItemDataRole.DisplayRole:
self._data[index.row()][index.column()] = value
return False
def rowCount(self, _):
return ROW_COUNT
def columnCount(self, _):
return COL_COUNT
app = qtw.QApplication()
view = qtw.QTableView()
view.setModel(Model())
view.setShowGrid(False)
view.verticalHeader().setVisible(False)
view.horizontalHeader().setVisible(False)
view.model().setData(view.model().createIndex(0, 0), "this is a test")
view.show()
app.exec()
You need to override the flags() and ensure that it doesn't return the ItemIsSelectable flag.
class Model(qtc.QAbstractTableModel):
# ...
def flags(self, index):
flags = super().flags(index)
if index.data() is None:
flags &= ~qtc.Qt.ItemIsSelectable
return flags
In your case, you also probably want to avoid the ItemIsEnabled, and since these two flags are the default one, you can just return NoItemFlags
def flags(self, index):
if index.data() is None:
return qtc.Qt.NoItemFlags
return super().flags(index)
If you also need to clear the selection, then you could subclass the view and do it in the mousePressEvent():
class TableView(qtw.QTableView):
def mousePressEvent(self, event):
index = self.indexAt(event.pos())
if index.isValid() and not index.flags() & qtc.Qt.ItemIsSelectable:
self.clearSelection()
else:
super().mousePressEvent(event)
i try to sequence some actions in urwid
I made a timer which run in background and communicate with the mainprocess
like this:
from multiprocessing import Process, Pipe
import time
import urwid
def show_or_exit(key):
if key in ('q', 'Q'):
raise urwid.ExitMainLoop()
class midiloop(urwid.Frame):
def __init__(self):
self.message = urwid.Text('Press Space', align='center')
self.filler = urwid.Filler(self.message, "middle")
super().__init__(urwid.Frame(self.filler))
def keypress(self, size, key):
if key == " ":
self.seq()
else:
return key
def timer(self,conn):
x = 0
while True:
if (conn.poll() == False):
pass
else:
z = conn.recv()
if (z == "kill"):
return()
conn.send(x)
x+=1
time.sleep(0.05)
def seq(self):
self.parent_conn, self.child_conn = Pipe()
self.p = Process(target=self.timer, args=(self.child_conn,))
self.p.start()
while True:
if (self.parent_conn.poll(None)):
self.y = self.parent_conn.recv()
self.message.set_text(str(self.y))
loop.draw_screen()
if ( self.y > 100 ):
self.parent_conn.send("kill")
self.message.set_text("Press Space")
return()
if __name__ == '__main__':
midiloop = midiloop()
loop = urwid.MainLoop(midiloop, unhandled_input=show_or_exit, handle_mouse=True)
loop.run()
The problem is i'm blocking urwid mainloop with while True:
So anyone can give me a solution to listen for key Q to quit the program before it reachs the end of the loop for example and more generally to interact with urwid and communicate with the subprocess
It seems to be rather complicated to combine multiprocessing and urwid.
Since you're using a timer and your class is called midiloop, I'm going to guess that maybe you want to implement a mini sequencer.
One possible way of implementing that is using an asyncio loop instead of urwid's MainLoop, and schedule events with the loop.call_later() function. I've implemented a simple drum machine with that approach in the past, using urwid for drawing the sequencer, asyncio for scheduling the play events and simpleaudio to play. You can see the code for that here: https://github.com/eliasdorneles/kickit
If you still want to implement communication with multiprocessing, I think your best bet is to use urwid.AsyncioEventLoop and the aiopipe helper for duplex communication.
It's not very minimal I'm afraid. However I did spend a day writing this Urwid frontend that starts, stops and communicates with a subprocess.

How can I set signal handler in target function?
multiprocessing.Process (cur_process in GUI) object would created and start when user click start button.
After that when user click stop button, I need to kill process gracefully.(send SIGTERM to cur_process when click stop button)
However, I am using Webdriver, so I want to quit Webdriver before kill process.
So I tried set signal handler in target function (test_main) but does not handle SIGTERM despite click stop button.
How I can set signal handler in Process target function?

The following script is part of a more complex one. I have taken out some parts just for simplification.
My aim is to insert a textedit field that captures the print output of the command window (when the pushbutton is pressed) and displays it inside the text field while the program is executing.
The suggestions I found are too much aimed at scripts that have no other functions. But my script is already quite complex and I don’t want to change it from the beginning or rewrite the whole script.
Does anyone have an idea on how to include the function in the script in a relatively simple way? I have tried it without success.
Any kind help would be appreciated.

My only GUI experience is with java.swing. I'm using PySide to update which of two QGridLayouts are set to a QLabel depending on a button press, but the actual update isn't happening. Making a call to self.update() after lines 123 and 130 didn't work. Should I be using a repaint event or something?

Also, the toolbar label at the top is way too big...
self.layout.setRowMinimumHeight(0,20)
self.layout.setColumnMinimumWidth(0,250)
self.layout.setColumnMinimumWidth(1,1000)
setColumnMinimumWidth() works fine but setRowMinimumHeight() doesn't seem to work at all. I'm still a little confused about how the size of QWidgets are affected by layouts, containers, and subwidgets...perhaps I need to adjust the size of the QLabel, toolbar?
Try using a QWidget instead of a QLabel for self.options. Does that change anything?
For the toolbar spacing, do addStretch() after you add the last widget to the layout, but note that if you use a layout in a toolbar, you lose the built-in capabilities for it to autosize and hide buttons in a "... more options ..." type thing.
Since you name your object a toolbar I would actually make it a QToolbar. I would like to point out some styling points, because you said you were new.
import * is always bad for many reasons. You should know what you are importing and from where.

Since you have a main GUI that you are running I would make that a QMainWindow. I would then add a menu bar and move some of your functionality to a file menu or edit menu.
