qprogressbar

问题 Appreciate if you could help me. I have a trouble showing up the progress bar while saving file to excel. What I want to achieve is to show a progress bar while saving excel file from a pandas dataframe also from qwidgettable as it takes time before it saves.

So far, this is the compiled codes I have created. import sys from PyQt5 import

问题 I have created a desktop application by PYQT5 and python 3.7 to download a video by clicking the download button and save it locally in the PC. The code will fetch the video link from (lineEdit.text()) which is labeled "URL" and save it in the local directory in (lineEdit_2.text()) which is labeled "SAVE AS" .

问题 How can I implement a progress bar in a pop-up window that monitors the progress of a running function from a so-called Worker class (i.e. time/CPU-consuming task) by means of a QThread ? I have checked countless examples and tutorials, but the fact that the progressbar shows up in a pop-up window seems to make everything harder. I believe what I want is a rather simple thing but I keep failing at it and I ran out of ideas. I have an example of what I am trying to achieve, which is based on

问题 I have the following code that works as expected. It updates the progress bar value in each for loop. The only issue I have is when I'm done and call emit ProcessUserRowsFinished() in the method OnProcessUserRowsStarted the program crashes. class UsersProcess: public QObject { Q_OBJECT public: UsersProcess(CTCore::DBConnect* db_context, UserSettingsMap user_settings_map); void SetProgressBar(QProgressBar *progress_bar); private: QProgressBar *progressBar; QSharedPointer<QList<CTCoreZen::User>

问题 I built a PyQt5 GUI to do some Selenium testing. Everything works as expected, except for the PyQt progress bar. In the first example below, where I use the Selenium browser, the progress bar just jumps to 100%, at the end, when the browser closes. But, the Selenium works as expected. def test(self): self.completed = 0 browser = webdriver.Firefox() links = ['http://www.somesite.com/', 'http://www.somesite.com/page2', 'http://www.somesite.com/page3'] for link in links: browser.get(link) self

问题 I have a GUI class created by Qt designer in which i have a progress bar, and another class in which all the number crunching is done during which i want my progress bar to update regularly. The way i thought i would do this it to do something like this in the other class: gui.progressbar.setValue(some%) but i cant seem to make that work. the code for the gui class is something like: from PyQt4 import QtCore, QtGui from Run import RunProgram class Ui_mainLayout(QtGui.QWidget): def setupUi

问题 If I want to update a QProgressBar on the view layers from a loop on the logic layer (such as each iteration will update the progress bar), what is the proper way to do that? Thanks 回答1: class LogicClass : public QObject { Q_OBJECT public: explicit LogicClass(QObject *parent = 0); int max(){ return 100; } int min(){ return 0; } void emit50(){ emit signalProgress(50); } signals: void signalProgress(int); public slots: }; MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui:

问题 I'm new to PyQt4 so maybe it is a bagatelle. I try to show a progress in my GUI, which will be updated by an worker thread.The QProgressBar is with other memory's in a QTableWidget. The worker thread starts in the init function of my GUI. self.st = ServerThread() self.st.start() Here is the thread class _exportedMethods = { 'changes': signal_when_changes, } class ServerThread(QtCore.QThread): def __init__(self): super(ServerThread,self).__init__() st = self #threading.Thread.__init__(self)
