I'm working with XMLs and I'm trying to delete <node> based on element's criteria. The idea is to delete 2nd ITEM. I tried to make list of ITEMS and then based on that list removed them from root lvl but I got
ValueError "ValueError: list.remove(x): x not in list"
and I have no idea how to get to higher lvl.
Code:
import xml.etree.ElementTree as ET
tree = ET.parse("PW.xml")
root = tree.getroot()
items = root.findall('.//ITEM[PROPERTY]')
m = -1
delate = []
for i in items:
pl = i.findall('PROPERTY[#NAME="ID detalu"]')
#print([(pv.attrib['NAME'], pv.text) for pv in pl])
m = m + 1
for p in pl:
if (p.text.startswith('SHP')):
delate.append(m)
tree.write('PW.xml')
XML:
<DATA>
<OBJECT TYPE="Dane">
<ITEM>
<PROPERTY NAME="[1]" />
<PROPERTY NAME="child2">0\557</PROPERTY>
<PROPERTY NAME="child3">MNO001366</PROPERTY>
<PROPERTY NAME="child4">1507</PROPERTY>
<PROPERTY NAME="child5" />
<PROPERTY NAME="child6" />
<PROPERTY NAME="ID detalu">PL.10.000033</PROPERTY>
</ITEM>
<ITEM>
<PROPERTY NAME="[1]" />
<PROPERTY NAME="child2">0\557</PROPERTY>
<PROPERTY NAME="child3">MNO001485</PROPERTY>
<PROPERTY NAME="child4">1626</PROPERTY>
<PROPERTY NAME="child5" />
<PROPERTY NAME="child6">Pintos</PROPERTY>
<PROPERTY NAME="ID detalu">SHP001432</PROPERTY>
</ITEM>
</OBJECT>
</DATA>
I cannot reproduce the error message. Anyway, to remove an element, you need to have a reference to its parent, so that you can do parent.remove(child). The parent of the ITEM elements is OBJECT.
Here is a demo:
import xml.etree.ElementTree as ET
tree = ET.parse("PW.xml")
root = tree.getroot()
to_delete = []
object = root.find("OBJECT")
items = root.findall(".//ITEM")
# Find the items to delete and add them to the to_delete list
for item in items:
prop = item.find("PROPERTY[#NAME='ID detalu']")
if prop is not None and prop.text.startswith("SHP"):
to_delete.append(item)
# Do the actual deletion of items
for item in to_delete:
object.remove(item)
print(ET.tostring(root).decode())
Output:
<DATA>
<OBJECT TYPE="Dane">
<ITEM>
<PROPERTY NAME="[1]" />
<PROPERTY NAME="child2">0\557</PROPERTY>
<PROPERTY NAME="child3">MNO001366</PROPERTY>
<PROPERTY NAME="child4">1507</PROPERTY>
<PROPERTY NAME="child5" />
<PROPERTY NAME="child6" />
<PROPERTY NAME="ID detalu">PL.10.000033</PROPERTY>
</ITEM>
</OBJECT>

I am creating a calorie calculator and I need to add foods dynamically. I am adding widgets dynamically. For example, I add a label. But after setObjectName I cannot access by that name. For example, I set the name for the label to "name". I am trying to get the text of the label by name with the following image name.text (), but the code is crashing. What am I doing wrong?
Here is the code:

You cannot simply access the object with the objectName. You'll need to use the findChild method.
OPTION 1:
self.widget_i_want = self.findChild(QLabel, "name")
But as #ekhumoro said, it is best if you use a list or a dict to store all the added labels.
OPTION 2:
class MyWin(QtWidgets.QMainWindow):
def __init__(self):
QtWidgets.QMainWindow.__init__(self)
uic.loadUi("gui.ui", self) # load ui
self.counter = 1 #this is going to be used to set unique names
self.add_product.clicked.connect(self.add)
self.remove_product.clicked.connect(self.remove)
self.dynamically_added_widgets = list()
def add(self):
self.counter += 1
h1 = QHBoxLayout()
self.label = QLabel()
self.label.setObjectName(f"name{self.counter}") # set a new, unique name
self.label.text = "L"
h1.addWidget(self.label)
h1.addWidget(QLabel('Weight'))
h2 = QHBoxLayout()
h2.addWidget(QLineEdit())
h2.addWidget(QLineEdit())
i = self.verticalLayout_2.count()
self.verticalLayout_2.insertLayout(i - 2, h1)
self.verticalLayout_2.insertLayout(i - 1, h2)
self.dynamically_added_widgets.append(self.label) # add the new label to list
print(self.dynamically_added_widgets)
print(self.dynamically_added_widgets[-1].objectName()) # print the last added label's objectName
def remove(self):
i = self.verticalLayout_2.count()
if i > 3:
QWidget().setLayout(self.verticalLayout_2.takeAt(i - 3))
QWidget().setLayout(self.verticalLayout_2.takeAt(i - 4))
I want to implement the functionality that multiple QTableWidgetItems inside of a QTableWidget can be selected and unselected so that the values and "positions" of those QTableWidgetItems is known for further use.
Inside of the QTableWidget there are some empty cells, for aesthetics/spacing, which should be ignored by the functionality I'm trying to implement.
But that could also easily be done afterwards by checking if a selected item does have content.
self.table_widget.itemClicked.connect(self.some_function)
Would be the signal best fitting but I cannot specify or know which item was clicked inside of the table widget or whether is was selected or unselected.
Question: How do I implement the functionality to emit a specific signal when a specific QTableWidgetItem is pressed?
Here some pseude code for use in examples:
class Window(QtWidgets.QMainWindow):
def __init__(self):
super(Window, self).__init__()
uic.loadUi("qtdesignerfile.ui", self)
self.show()
#connect signal to function
self.table_widget.itemClicked.connect(self.some_function)
#create "global" list to save all selected items
self.selected_items = []
#some function to execute the logic
def some_function(self):
#condition distinguishing if item was just selected or unselected
if QTableWidgetItem(row, column) is not already selected:
#change background color to indicate selection
self.table_widget.item(row,column).setBackground(QtGui.QColor(100,100,100))
#"format" information of clicked item for further use
selected_item = [str(table_widget.item(row,column).text()), row, column]
#"save" selected item in global list for further use
self.selected_items.append(selected_item)
#condition distinguishing if item was just selected or unselected
if QTableWidgetItem(row, column) is already selected:
#change background color to indicate un-selection
self.table_widget.item(row,column).setBackground(QtGui.QColor(0,0,0))
#"format" information of clicked item for further use
selected_item = [str(table_widget.item(row,column).text()), row, column]
#remove the un-selected item from global list
self.selected_items.remove(selected_item)

I am really puzzled on how to easily implement this functionality and am open to suggestion on a different approach.
The user of the application should be able to select multiple QTableWidgetItems so that the information of the row the item is inside can be transferred to another QTableWidget for further use.
The itemClicked signal does pass the element that is pressed if the element exists, by default Qt Designer only creates elements in which it edited, where appropriate where it placed text.
from PyQt5 import QtCore, QtGui, QtWidgets, uic
SelectedRole = QtCore.Qt.UserRole + 1000
class Window(QtWidgets.QMainWindow):
def __init__(self):
super(Window, self).__init__()
uic.loadUi("qtdesignerfile.ui", self)
# self.tableWidget.setEditTriggers(QtWidgets.QAbstractItemView.NoEditTriggers)
self.tableWidget.itemClicked.connect(self.onClicked)
#QtCore.pyqtSlot(QtWidgets.QTableWidgetItem)
def onClicked(self, it):
state = not it.data(SelectedRole)
it.setData(SelectedRole, state)
it.setBackground(
QtGui.QColor(100, 100, 100) if state else QtGui.QColor(0, 0, 0)
)
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
w = Window()
w.show()
sys.exit(app.exec_())
I have two Gtk.Comboboxes on a main window :
the first, has its own Gtk.Liststore
the second one, linked to a Gtk.TreeModelFilter which is linked to a second Gtk.Liststore
When I select a value in the first one, the second one displays values according to my selection. This works well in the main window.
But in my application, I need to use this comboboxes combination many times, and when I use it on another window, this generates a Gtk Error that I don't understand:
"Gtk-CRITICAL **: 00:27:38.289:
gtk_tree_model_filter_set_visible_func: assertion
'filter->priv->visible_method_set == FALSE' failed"
Could someone explain me what's wrong with my code and what is the meaning of that error message?

Thank you in advance.
The problem was due to the fact that the second combobox on the main window and the second combobox on 'other' window were using the same filter.
I've created another filter and the second comboboxes have now their own filter linked to a common Gtk.Liststore.
Everything works fine, now.
Here are the corrected files :

My code is:
xmldoc = minidom.parse('C:\Users\qxn5622\Desktop\EF10018\DEFAULT.tbc')
propertyList = xmldoc.getElementsByTagName('PROPERTY')
for prop in propertyList:
if prop.attributes["name"].value == "ModelDir":
myString = prop.getElementsByTagName("VALUE").value
I think the problem is that the element I am trying to get doesnt have any Id.
Can anybody help me?
This might help
from xml.dom.minidom import parse
dom = parse('C:\Users\qxn5622\Desktop\EF10018\DEFAULT.tbc')
propertyList = dom.getElementsByTagName('PROPERTY')
for prop in propertyList:
if prop.getAttribute('name') == "PrjFile":
myString = prop.getElementsByTagName("VALUE")
print myString[0].firstChild.nodeValue

I'm trying to setup a little download application using Glade, PyGTK, and Python. I have it planned how I'd like to script this progress bar and all, though I feel I'm going about it the wrong way as... Well... It's not working.
I'm using a little script I found for a checking the percentage of a download and then usually it would print to terminal, but instead I'd like it alter a label in Glade. Though, instead of the label changing when as the download progresses, the GUI freezes until the file is done and THEN updates saying it's 100% complete.
What would be the best method about making something like this work? Any help is appreciated, thanks in advance!

After the line
self.label1.set_text(status)
Add:
while gtk.events_pending():
gtk.main_iteration()
This will update the GUI and run the main loop while you are waiting for the file to download, and you won't have to use threads.
You will need to use threads for this. If you are downloading in the callback function then the eventing is blocked on the button & you can see that the button is in pressed state i.e. it is waiting for the callback function to complete and return. Although my knowledge of python is nil, I could cook up some sample as follows using google etc:
import sys
import pygtk
pygtk.require("2.0")
import gtk
import gtk.glade
import urllib2
import time
import threading
import glib
# Replace this with what you want to do
def download(label):
index = 0
while True:
if index>1200:
break
index += 120
time.sleep(1)
status = r"%10d " % (index)
label.set_label(status)
class FileSelector:
def __init__(self):
#Set the Glade file
filename = "FileSelector.glade"
self.builder = gtk.Builder()
self.builder.add_from_file(filename)
self.builder.connect_signals(self)
self.window = self.builder.get_object("MainWindow")
self.label1 = self.builder.get_object("label1")
def on_MainWindow_destroy(self, obj):
gtk.main_quit() #make the program quit
def btnSubmit_clicked(self, widget):
status_dropbox = self.builder.get_object("chkboxDropbox")
status_python = self.builder.get_object("chkboxPython")
status_chrome = self.builder.get_object("chkboxChrome")
# Launch the thread to update label
threading.Thread(target=download, args=(self.builder.get_object("label1"),)).start()
if __name__ == "__main__":
FileSelector()
glib.threads_init()
# Add gdk thread enter and leave
gtk.main()
You can refer this question as well.
Hope this helps!
PS: Add thread safety & maybe disable button till download is complete?
