Language Bindings

@nullbuil7 said in how do i separate these sudoku boxes (grids):

import sys
from PySide2.QtWidgets import *
from PySide2.QtGui import *

class SudokuGrid(QWidget):
def init(self):
super(SudokuGrid, self).init()
self.initGUI()

def initGUI(self): self.setWindowTitle("Sudoku Grid Example") self.setGeometry(800, 800, 400, 350) self.setGrid() def setGrid(self): gridLayout = QGridLayout() box1 = QGridLayout() box2 = QGridLayout() box3 = QGridLayout() box4 = QGridLayout() box5 = QGridLayout() box6 = QGridLayout() box7 = QGridLayout() box8 = QGridLayout() box9 = QGridLayout() hline = QFrame() hline.setFrameShape(QFrame.HLine) hline.setFrameShadow(QFrame.Sunken) vline = QFrame() vline.setFrameShape(QFrame.VLine) vline.setFrameShadow(QFrame.Sunken) gridLayout.addLayout(box1,0,0) gridLayout.addWidget(vline, 0, 1) gridLayout.addLayout(box2,0,2) gridLayout.addWidget(vline, 0, 3) gridLayout.addLayout(box3,0,4) gridLayout.addWidget(hline, 1, 0, 1, 5) gridLayout.addLayout(box4,2,0) gridLayout.addWidget(vline, 2, 1) gridLayout.addLayout(box5,2,2) gridLayout.addWidget(vline, 2, 3) gridLayout.addLayout(box6,2,4) gridLayout.addWidget(hline, 3, 0, 1, 5) gridLayout.addLayout(box7,4,0) gridLayout.addWidget(vline, 4, 1) gridLayout.addLayout(box8,4,2) gridLayout.addWidget(vline, 4, 3) gridLayout.addLayout(box9,4,4) pos = [(0,0),(0,1),(0,2), (1,0),(1,1),(1,2), (2,0),(2,1),(2,2)] i = 0 while i < 9: box1.addWidget(QLabel("1", self), pos[i][0], pos[i][1]) box2.addWidget(QLabel("1", self), pos[i][0], pos[i][1]) box3.addWidget(QLabel("1", self), pos[i][0], pos[i][1]) box4.addWidget(QLabel("1", self), pos[i][0], pos[i][1]) box5.addWidget(QLabel("1", self), pos[i][0], pos[i][1]) box6.addWidget(QLabel("1", self), pos[i][0], pos[i][1]) box7.addWidget(QLabel("1", self), pos[i][0], pos[i][1]) box8.addWidget(QLabel("1", self), pos[i][0], pos[i][1]) box9.addWidget(QLabel("1", self), pos[i][0], pos[i][1]) i = i + 1 self.setLayout(gridLayout)

if name == 'main':
try:
myApp = QApplication(sys.argv)
myWindow = SudokuGrid()
myWindow.show()
myApp.exec_()
sys.exit(0)
except NameError:
print("Name Error:", sys.exc_info()[1])
except SystemExit:
print("Closing Window...")
except Exception:
print(sys.exc_info()[1])

Its not a bug in Qt or PySide2: you can't add a widget to a layout multiple times; you only create one each ofhline and vline and add them to multiple locations in your layout. See my example below where I create a new instance of hline and vline each time I use them (and tidied things up a bit):

from PySide2.QtWidgets import QWidget, QGridLayout, QFrame, QLabel class SudokuGrid(QWidget): def __init__(self, parent=None, **kwargs): super().__init__(parent, **kwargs) self.setWindowTitle("Sudoku Grid Example") self.setGeometry(800,800,400,350) l=QGridLayout(self) boxes=[] for i in range(9): col=i%3 row=i//3 box=QGridLayout() boxes.append(box) l.addLayout(box, row*2, col*2) if col<2: vline=QFrame() vline.setFrameShape(QFrame.VLine) vline.setFrameShadow(QFrame.Sunken) l.addWidget(vline, row*2, (col*2)+1) if col==2 and row<2: hline=QFrame() hline.setFrameShape(QFrame.HLine) hline.setFrameShadow(QFrame.Sunken) l.addWidget(hline, (row*2)+1, 0, 1, 5) for box in boxes: for i in range(9): col=i%3 row=i//3 box.addWidget(QLabel(str(i),self), row, col) if __name__=="__main__": from sys import argv, exit from PyQt5.QtWidgets import QApplication a=QApplication(argv) s=SudokuGrid() s.show() exit(a.exec_())

I've tested this with PyQt5 not PySide2, but they are compatible and this code should work perfectly well.

Hope this helps ;o)

Hi
Should it not be on the application like ?
QtGui.QApplication.setStyle(QtGui.QStyleFactory.create('Fusion'))

Relating to attaching Debugger to Valgrind PID, when I launch qtcreator

./qtcreator

The following messages appear before launching
Analyze->Valgrind Memory Analyzer with GDB
Debug->Attach to Running Application

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'

Hi,

What version of Qt are you using ?
What Linux distribution are you running ?
What versions of OpenSSL do you have installed ?

You are not connecting the error related signals anywhere, you should so you'll have more information about what is going wrong.

On a side note, there's no need to create your QNetworkRequest on the the heap as shown in the QNetworkAccessManager documentation.

@aha_1980 I will try compiling it myself since I'd like to stick with MinGW.

Just tried that but MinGW outputs the following:
0 [main] sh 1816 sync_with_child: child 12536(0x1E4) died before initializing with status code 0xC0000142
208 [main] sh 1816 sync_with_child: *** child state waiting for longjmp
/usr/bin/sh: fork: Resource temporarily unavailable
mingw32-make: *** [Makefile:55: mingw] Error 128

@Nathan-Miguel
Look, the "dots" aren't part of a file name, they are the . and the .. entries in the directory, The other two are filenames. You are choosing to print them out all touching each other (testlist.join("")). Clearly that has nothing to do with your "want to set to open a file inside the folder". You can access indvidual files via each element in entryList() or entryInfoList(), as you please.

Can you rather post a minimal example that shows that behaviour ?

Because the environment variable is described here. The fact that you are using python is of no importance here.

@skylendar Sorry, I miss your last message.
Any improvements here ?

Hi and welcome to the forums
I dont know Golang but the interface is the same so i would
check in func (m *CustomTableModel) data
that this test
if role != int(core.Qt__DisplayRole) {
return core.NewQVariant()
}

is not always returning an empty variant for each call.

also
case 0:
return core.NewQVariant12(item.firstName)
case 1:
return core.NewQVariant12(item.lastName)

does return a valid QVariant ?

i wondered why the empty one is
NewQVariant()
but with data its NewQVariant12 ?

@Mayankjain
C is plain better (IMHO) :) But for your career, C++ is definitely more advisable!

Hello,

I'm facing the same issue.

Have you solved this problem?

Hi,

AFAIK, there's none. You need to implement your own macro on top Q_PROPERTY to do that.

So I give up. I'll declare a method instead.

Maybe in a further version of Qt5.

Thank you anyway.

@Nathan-Miguel said in Read a specific tag in xml:

PROGRAM DIRECTORY: E:\Git\Denoiser-Script\QML_C++\build-Denosier-Desktop_Qt_5_12_3_MSVC2017_64bit2-Debug\debug

In your code extract you have hard coded the path and with you output it should be:

QString systeminfo::getCpuName() { QString rootDir = qApp->applicationDirPath(); // QDir::currentPath() != not application path QString xmlDir = "/sysinfo/system.xml"; QDomDocument docxml; QString test; QFile xmlread; xmlread.setFileName(rootDir+xmlDir); test = "head"; if (xmlread.open(QIODevice::ReadOnly)) { QXmlStreamReader reader(&xmlread); if (docxml.setContent(&xmlread)){ //Open xml with success test = "xml loaded with success"; //Read specifc tag xml auto nodes = docxml.elementsByTagName("cpuname"); for(int i = 0; i < nodes.count(); i++) { QDomNode elm = nodes.at(i); if(elm.isElement()) { test = QStringLiteral("%1 = %2").arg(elm.toElement().tagName(), elm.toElement().text()); } } } } return test; }

==> my output with this code and your XML document is:
0_1561445518059_240c2702-943f-4bcc-b78f-e2a3dabc860e-image.png

Hi @semtexzv, and welcome!

@semtexzv said in Generating bindings for other languages:

...mainly utilize Rust language.

Have you seen the Rust-Qt project? https://github.com/rust-qt

could the shiboken generator used to generate bindings for other languages in custom format ?

I'll leave this question for someone else who has experience with Shiboken. But if you want to check yourself, this is a good place to start: https://blog.qt.io/blog/2018/05/31/write-python-bindings/
