@JonB Thank you for interactions. Would you please show me an exact code of for example a PushButton and where to implement it. I am advanced python coder, I just need to see exact steps. Thank you very much.

@KroMignon Well, i try to learn from anothers in every forum, sorry :), @jsulm Thank you Sir, you are a Life saver :)

@Stainopel None of this seems relevant. Either you don't really want separate applications but just one and you just want to show the other widget. Or, to run another application as you ask, use Qt's QProcess, or the Python ones for running sub-processes if you prefer, called from your button clicked slot.

@JonB Very Good Suggestion, I used a second variable in the other function to read the opened file(s) from the first function and it did work like a charm. Thanks. Here is an update to the code def encryption_hash(self,comboBox_2): index = self.comboBox_2.currentIndex() path = self.fname_E with open(path, 'rb') as f: if index == 2: hasher1 = hashlib.md5() afile1 = f buf1 = afile1.read() a = hasher1.update(buf1) md5 =(str(hasher1.hexdigest())) self.lineEdit_E.setText("File Hash Using MD5: " + md5)

@Pl45m4 yes I initially used a line edit but ended up changing it to a qtextedit instead. Then using the documentation I was able to get the expected results

Thanks for the links !

In case anyone comes across this in a search, I was able to solve the problem by manipulating the selection in the class member function selectionChanged(): https://bazaar.launchpad.net/~dlynch3/rapid/zeromq_pyqt/revision/1178#raphodo/thumbnaildisplay.py Perhaps that was always the best way to do it.

Hi @dridk2 , I wish to help you with this project.

try to add this to main.py import os os.environ["QT_IM_MODULE"] = "qtvirtualkeyboard"

Hi, You can put your QStackedLayout and buttons in a QVBoxLayout so you can re-use the buttons. Put that layout in a QWidget and set that widget as the central widget of your QMainWindow.

@raven-worx you sir saved my life! I cant believe i was stuck at this for 2 days, when it was simply just about using the right object in qml. thanks!

@GLaDOS1105 I hit the same problem recently trying to send messages from a PySide2.QRunnable via PyPubSub to the main GUI thread. The only thing I can recommend is to try adapting your code to using the QThreadPool class instead of the multiprocessing module.

Hi there. I think you can use TableViewColumn element to create a new column inside a TableView component. If necessary, you can define your own delegate to set how the data is showed to user.

@germyrinn Hi, this was an old post of mine. As I wrote, the problem is that for the £ sign e.g. read from a file created in the way I describe, decode("utf-8") gives me a UnicodeDecodeError. I found the only conversion which works is decode("cp850").

@Fuel the exemples in pyqt-master do it automatically but i don't understsnd what event or property they use

I have found a solution that kind of does the job, although takes three times as much memory. Every update I calculate the difference between the new and the old saturation matrix, this eliminates 60% of the nonzero values, which means it gets drawn that much faster. As a second layer of optimization I call repaint with a rectangle describing the most important zone, and call update every 60ms.

@Pierone Can you put you code in GitHub instead of a rar file? Its pretty awkward to unpack your code.

@Pataruutu Hi the video you link is QML :) So its its the reason it looks differently. The one you call ugly is QWidgets and it uses the default look of the platform. It seems you can use QML with pyt http://pyqt.sourceforge.net/Docs/PyQt5/qml.html

Thanks @jsulm!! That sorted it!

Hay i saw your keyboard its really good, i also want to design this kind of keyboard, can you please tell me when i move the cursor on the keys it automatically enlarge. how is it possible ? and another one is, when i am typing it does not show anything but my only cursor move forward.

Thank you! I didnt noticed that. I did correct this mistakes, but still getting the same error:( and empty window :/

I did the test and appearantly it's the painting which is very expensive... with no slot connected, the program takes 1,5 seconds to complete the task. There is a very similar issue reported at https://bugreports.qt.io/browse/QTBUG-49655. But generally ProgressBars are consuming especially when we update it that often (>365000 times) while there is no significant change at each iteration. So I simply update the QProgressBar less often and the results are good (~1s) and the progression still smooth. PSB : class ParseFileAsync(QtCore.QThread): match = QtCore.pyqtSignal(str) PBupdate = QtCore.pyqtSignal(int) PBMax = QtCore.pyqtSignal(int) def run(self): with open("test_long.log", "r") as fichier: fileLines = fichier.readlines() self.lineNumber = len(fileLines) self.PBMax.emit(self.lineNumber) if (self.lineNumber < 30): self.parseFile(fileLines, False) else: self.parseFile(fileLines, True) def parseFile(self, fileLines, isBig): cpt = 0 if(isBig): for line in fileLines: cpt+=1 if(cpt % (int(self.lineNumber/30)) == 0): self.PBupdate.emit(cpt) for element in liste: if element in line: self.match.emit(line) self.PBupdate.emit(self.lineNumber) #To avoid QProgressBar stopping at 99% else: for line in fileLines: cpt+=1 self.PBupdate.emit(cpt) for element in liste: if element in line: self.match.emit(line)

super :) also using "#MainWindow" makes sure it dont apply to childs as stylesheets does.

@Kourpetis Hi, it sounds like your code is getting stuck in your while loop. I believe your code needs threading.

How can i create my signal for text edit with python3 ? With as many ways i tried, but I did not succeed .. :(
