I have a QListWidget containing one item, I want the item’s texts to be partially bold, so I created a QItemWidget for it. I use a QLabel in it to display the partially bold texts, the code is as follows:
I’m using Qt Designer for design GUI to use in python, after designing my desired UI in Qt Designer, convert it to python code and then I changed generated code to do some action in my python code, but if I changed the UI with Qt Designer and convert it to python code again, I lost my previous changes on my code.
I was researching for some time to find information how to do multithreaded program using PyQT, updating GUI to show the results.
I have a program which interfaces with a radio I am using via a gui I wrote in PyQt. Obviously one of the main functions of the radio is to transmit data, but to do this continuously, I have to loop the writes, which causes the gui to hang. Since I have never dealt with threading, I tried to get rid of these hangs using QCoreApplication.processEvents(). The radio needs to sleep between transmissions, though, so the gui still hangs based on how long these sleeps last.
Is it possible to pass variables through slots so I can print out certain text?
Trying to pass variable ‘DiffP’ which is defined in another function to slot.
I’m using PyQt and am running into this issue. If my import statements are:
I am trying to connect slots with lambda functions, but it’s not working the way I expect. In the code below, I succeed in connecting the first two buttons correctly. For the second two, which I connect in a loop, this goes wrong. Someone before me had the same question (Qt – Connect slot with argument using lambda), but this solution doesn’t work for me. I’ve been staring at my screen for a half hour, but I can’t figure out how my code is different.
I’m using Qt’s QWebPage to render a page that uses javascript to update its content dynamically – so a library that just downloads a static version of the page (such as urllib2) won’t work.
I’m writing a GUI application that regularly retrieves data through a web connection. Since this retrieval takes a while, this causes the UI to be unresponsive during the retrieval process (it cannot be split into smaller parts). This is why I’d like to outsource the web connection to a separate worker thread.
Try to link PyQt and Opencv video feed, can’t understand how to apply while loop for continuously streaming video. It just take a still picture.Please can anyone help to solve the problem.
