qlabel

I access the Qt GUI's QLabel's QPixmap in another thread since I will finally use this to display mjpeg stream in QLabel, and I decided to use QLabel since its the easiest way It should look like 'Live' and not block the UI thus using another (non-gui) thread. nothing shows up in the QLabel. only the exception QPixmap: It is not safe to use pixmaps outside the GUI thread any better or correct way to do this ? here is my PyQt code of another thread: self.theQlabel.setPixmap(QtGui.QPixmap.fromImage(myQimg) Instead of directly setting the pixmap, make the external thread emit an updatePixmap

Im working on a simple project in QtCreator where you input text into a line_edit which then gets printed after clicking a button. It works but I need to resize the window in order to see the updated/changed display. So starting off with the main.cpp, I have left it as default after some tests: #include "mainwindow.h" #include <QApplication> int main(int argc, char *argv[]) { QApplication a(argc, argv); MainWindow w; w.show(); return a.exec(); } That has the issue I was talking about above. I decided to add w.update(); and see if that fixed the issue, it did not. I thought maybe it was because

I am beginner in Qt, now I want to make my label clickable, I have searched so much online, but no one gives my a real example of how they made it. So can someone teach me step by step? Now my basic thinking is creating a new .c file and new .h file respectively and then include them into my mainwindow.c and then connect it with the existing label in ui form. These are what I was trying to do, but can not make it. Hope someone can teach and better put the step picture in the command, thanks. Here is the clicklabel.h code: #ifndef CLICKEDLABEL_H #define CLICKEDLABEL_H #include <QWidget>

I want to display some string in QLabel on button click but my code only shows first char of the string. I am using following code for this class UITesterWindow(QWidget): def __init__(self, parent=None): super(UITesterWindow, self).__init__(parent) self.test2 = QPushButton("Test1", self) self.test2.setGeometry(10, 360, 200, 30) self.test2.setStyleSheet("font: bold 12pt Courier") self.emailIDIN = QtGui.QLabel(self) self.emailIDIN.setStyleSheet("font: bold 18pt Courier") self.emailIDIN.move(420, 170) class SecondWindow(QMainWindow): def __init__(self, parent=None): super(SecondWindow, self)._

I am trying to display a loading gif after a button is pressed. This is the code I currently have import sys from PyQt4 import QtGui, QtCore from PyQt4.QtCore import * from PyQt4.QtGui import * class MainWindow (QtGui.QMainWindow): def __init__(self, parent=None): super(MainWindow,self).__init__(parent) self.setGeometry(50,50,240,320) self.home() def home(self): but = QtGui.QPushButton("Example", self)#Creates the brew coffee button but.clicked.connect(self.gif_display) but.resize(200,80) but.move(20,50) self.show() def gif_display(self): l = QMovieLabel('loading.gif') l.show() class
