Language Bindings

@Dl10 Hi I think it exists https://www.youtube.com/watch?v=Dmo8eZG5I2w There you just place 4 qframes on center mainwindow Then right click (not on frames) and from layout menu select Grid layout

@SGaist Thanks for the reply. It has the same behavior in the MATE desktop environment. So far I've also tried in Unity and Gnome 3.0 as well.

@Dl10 You may split the function and start a timer.. something like.. from : testFunction(){ step1.. step2.. time.sleep().. step3.. } to testFunction(){ step1.. step2.. qtimer t; connect(&t,SIGNAL(timeOut()),this,SLOT(testFunction2())); t.start(2000); } testFunction2(){ step3... } PS: Syntax may vary.. this is a c++ code.. please convert it to pyqt5.. Hope this is what you are expecting... and thats what i understood from your post...

Hi and welcome to devnet, What slider are you talking about ?

Well, for right or for wrong architecturally, I ended up writing a function (Python, but you get the drift :) ): def findMainWindow() -> typing.Union[QMainWindow, None]: # Global function to find the (open) QMainWindow in application app = QApplication.instance() for widget in app.topLevelWidgets(): if isinstance(widget, QMainWindow): return widget return None No Python global variables --- which I now understand, are about as "global" as the parochial village I live in, are misnamed really, and are brain-dead in the way they work :)

@jazzycamel That worked! How would I load a UI file in the Widget class? I tried using uic.loadUI(), but that seems to override the previous gui.

hmmm.... right but i thing not in analog input/output.

@JNBarchan it's being worked on. Getting something like that back up to date takes time. It was left behind for a long time. I mentioned it, as it will at some point be an option.

Yeah i feel like i do sudo apt-get update && upgrade at least once a day. I just checked about SIP and i compiled it from source but i cant remember if i actually used the command make and make install. Does that mean i have to reinstall pyqt5 again? I guess i just open a new thread. Thanks for all the help @SGaist

Hi @J-Hilk thanks for your reply. Your help is much appreciated :)

what i was describing, fits your 3rd point more. i would want to use c++ but for some part of the program, python does the job better than c++ that's why i also need python but maybe 1st point is good too. only pyqt

@jsulm As I said, I totally understand that, I was not complaining, in this question I was just trying to clarify the Python behaviour so that I may bear it in mind when I read answers elsewhere. Which I believe we have now indeed covered here, thank you.

What behaviour do you get with QSplitter ?

Hey @m-sue , thanks for your reply. The problem isn't that cursor.movePosition(QTextCursor.NextCharacter) does not move the cursor, but rather that self.setHtml() sends the cursor to the end regardless of its current position. This does not explain why self.setTextCursor(cursor) has no effect.

@Fahad-H I need to sort out an issue in an existing Ubuntu 10.04 system which runs qt4 package. I assume the machine you are using is not the actual one which was used to do the compilation originally? I tried to install gcc drivers and all, but still some compatibility issues are there and the issue still persists. You are going to need to correctly install and set up g++. http://ubuntuguide.net/how-to-install-and-setup-gcc-4-1g4-1-in-ubuntu-10-0410-10 https://askubuntu.com/questions/928510/problem-in-installing-g-in-ubuntu-10-04 https://stackoverflow.com/questions/14969853/what-packages-are-needed-on-ubuntu-10-04-to-run-programs-compiled-with-gcc-g-4 It might help if you knew precisely what version of g++ the software you have was compiled for when working. But I don't suppose you know that? BTW: I just updated one qt4 (*.pro) program Do you actually need to update the .pro file for some reason? Or do you mean you've made a change in the source code?

@SGaist I need the slot send_console_log to be called when the signal written in ConsoleStream is emitted. When running the program with a normal while/for loop in the interpreter, the slot will be called becuase at that moment its non blocking. But the moment I add time.sleep into a loop, slots will only be called at the end when all the blocking is over. Thank you for looking into this.

Great ! Then please mark the thread as solved using the "Topic Tools" button so that other forum users may know a solution has been found :)
