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
Output:
W:\_fdsw\Projects\HIL\releases\release_9_1_0\Config\CDNG\UX_EF_TSHIL\UX_EF_TSHIL.CDP

How to call function when space key is pressed inside the lineEdit

I want to call a function that checks words count in a lineEdit whenever I press space key inside the lineEdit. But how can I do that. After executing the python file press 'Start Game' to go to the lineEdit. Thanks!

The sentences for a function in my code:
He found himself sitting at his computer, typing whatever came to mind. He was on a website entitled 10 fast fingers. This site tested how fast you were at typing. So he typed. He was currently typing about himself typing, which is odd in a way. He was now describing about how he was typing about himself typing.
The Internet is the global system of interconnected computer networks that uses the Internet protocol suite to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.

self.space_count = 0
self.startBtn.clicked.connect(self.start_game)
self.retryBtn.clicked.connect(self.goto_home_page)

Deleting xml node from tree based on element criteria

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>

Unable to Resize Column Contents according to the values of the column

I have a table which is being populated by the Database (MySQL) at the backend.
I am trying to resize the Columns according to the contents of each column (as much the stretch is possible), however I can't seem to do it.
I looked it up on Stackoverflow and found that I can do it by setting the QScrollAbstractArea.sizeAdjustPolicy to AdjustToContents in the Qt Designer.
I did this but it still did not work.
I further looked it up and found different solutions. One of them was this as well but it also did not work for me,
self.ui.course_table.horizontalHeader().setSectionResizeMode(0, QtWidgets.QHeaderView.Stretch)
self.ui.course_table.horizontalHeader().setSectionResizeMode(1, QtWidgets.QHeaderView.ResizeToContents)
self.ui.course_table.horizontalHeader().setSectionResizeMode(2, QtWidgets.QHeaderView.ResizeToContents)
I have shared a picture of my current table right now and I want to expand each column according to the content I have.
As you can see, there is a lot of space that can be stretched but it is not doing it despite having enough space. Even the Column names are not fully visible and some characters are cut off
In not maximized window form, this is what I get
As for my data, it is coming from MySQL database and it is attached to Button Click (whenever I click on the "Courses" button on the side menu, it will populate the data on the table in the Courses Page)
The function that is populating the table is as follows,
def get_course_data(self):
mycursor = self.DB.cursor() # DB is an object of class
Subquery = "Select course_name, course_code, course_type from tbl_course"
mycursor.execute(Subquery)
numcols = len(mycursor.fetchall()[0])
mycursor.execute(Subquery)
numrows = len(mycursor.fetchall())
self.ui.course_table.setRowCount(numrows)
self.ui.course_table.setColumnCount(numcols+1)
mycursor.execute(Subquery)
tablerow = 0
for row in mycursor.fetchall():
tablecol = 0
layout = QHBoxLayout()
layout.setContentsMargins(0, 0, 0, 0)
layout.setSpacing(0)
delete_button = QPushButton()
icon_delete = QIcon()
icon_delete.addFile(u":/icons/icons/Delete-button.png", QSize(), QIcon.Normal, QIcon.Off)
delete_button.setIcon(icon_delete)
layout.addWidget(delete_button)
edit_button = QPushButton()
index = PySide2.QtCore.QPersistentModelIndex(self.ui.course_table.model().index(tablerow, tablecol))
edit_button.clicked.connect(lambda *args, index=index: self.on_course_edit_click())
icon_edit = QIcon()
icon_edit.addFile(u":/icons/icons/edit-button.png", QSize(), QIcon.Normal, QIcon.Off)
edit_button.setIcon(icon_edit)
layout.addWidget(edit_button)
cellWidget = QWidget()
cellWidget.setLayout(layout)
self.ui.course_table.setCellWidget(tablerow, 3, cellWidget)
while tablecol < numcols:
self.ui.course_table.setItem(tablerow, tablecol, PySide2.QtWidgets.QTableWidgetItem(str(row[tablecol])))
tablecol += 1
tablerow += 1
self.ui.course_table.horizontalHeader().setSectionResizeMode(0, QtWidgets.QHeaderView.Stretch)
self.ui.course_table.horizontalHeader().setSectionResizeMode(1, QtWidgets.QHeaderView.ResizeToContents)
self.ui.course_table.horizontalHeader().setSectionResizeMode(2, QtWidgets.QHeaderView.ResizeToContents)
The layout of this page of mine is as follows, (it basically has three frames who are in horizontal layout and the third frame contains the QTableWidget. The third frame's sizePolicy is set to Expanding so that it covers the whole main body while the two other performs are aligned to the top of the main body)

Designer Overlapping Issue

I'm having an issue where widgets and layouts starts overlapping inside my scroll area.
My current layout is supposed to be like this:
My layout:
But ends up like this where the widgets starts overlapping (this is with fixed size group box):
Overlapping example:
Or this (without fixed size group box):
"Sqished" widgets and pushed out of view widgets:
I've tried setting fixed sizes and minimum sizes and changing size policies, but whatever I do some widgets get resized anyways and some get overlapped, and some gets pushed out of view.
I am using designer and PyUIC.
This is my hierarchy if that helps:

Update: Thanks a lot for the quick and comprehensive answer. For posterity the main fault that caused my issues was that I didn't know setting the minimum size back to 0x0 was not the same as resetting it. Resetting the minimum size of my scroll area and group boxes fixed it!
You've set a minimum height for the scrollAreaWidgetContents container of the scroll area. This results in overriding the minimumSizeHint of the container (which is computed using the minimum size required by all of its items and ensures that all widgets are properly displayed), so the scroll area forces it to be smaller than it should until that minimum height is reached, even if this makes some widgets unusuable or even invisible.
Reset that property completely (using the small red arrow button of the minimum size field) and the widgets will only be resized to their own minimum default size.
Also be aware that you've set a lot of other size related properties that should not be set unless really needed:
the baseSize property is only useful for top level windows and if the sizeIncrement has been set, it's not the "suggested" size of the widget (that depends on the widget's sizeHint; reset all those properties, as they are useless for child widgets;
reset all minimumSize properties that are set to 0x0 or, for container widgets, that are set with size that wouldn't probably allow their children to be properly displayed (same issue as the scroll area);
reset the size policies overrides, unless you really know how they work;
reset the size hint of the spacers, as the stacked widget already takes care of the minimum size required for all its pages, so using a minimum height for spacers can result in having unused blank spaces;
All the reset indications above mean using the small red arrow button, which actually resets the property to the default state of the widget. Note that manually setting a value to what appears to be the default one is not the same as resetting it: the default value of properties can depend on different aspects and might not be the same for all widgets and situations (including the OS/style), and while using the default (property unset) ensures that Qt properly uses the default expected behavior, explicitly setting a value might not have the same result even if it seems the default.
Further suggestions:
the scrollAreaWidgetContents already has a vertical layout set, but you're using a further nested vertical layout that is almost useless. Move every widget from that nested layout to the main one of the scroll area and delete that layout;
form layouts are normally suggested for extended (and possibly dynamic) interfaces; you can use a normal grid layout for the bottom part, since it only contains 3 widgets, and you should also set the checkbox text instead of using a label (the standard convention for checkboxes says that their label should be on the right);
check the tab order, because it seems a bit confused;

Emiting QTableWidgetItem specific signal on being clicked

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_())
