  @VRonin Oh yeah that was brought up a few times and I'm aware of it. But the stackoverflow version was not a good mvce. I suppose the GitHub version explains the issue better. The loop actually runs in an environment without access to qt UI or its variables. I'm still writing the buffer so will keep this posted unless I can't figure out the buffer flush myself.

  PyQt example

  #! /usr/bin/env python # -*- coding: utf-8 -*- # # Here we provide the necessary imports. # The basic GUI widgets are located in QtGui module. import sys from PyQt4.QtGui import QApplication, QWidget # Every PyQt4 application must create an application object. # The application object is located in the QtGui module. a = QApplication(sys.argv) # The QWidget widget is the base class of all user interface objects in PyQt4. # We provide the default constructor for QWidget. The default constructor has no parent. # A widget with no parent is called a window. w = QWidget() w.resize(320, 240) # The resize() method resizes the widget. w.setWindowTitle("Hello, World!") # Here we set the title for our window. w.show() # The show() method displays the widget on the screen. sys.exit(a.exec_()) # Finally, we enter the mainloop of the application.

  Hi and welcome to devnet,

  That version of QtJambi is not part of Qt. In fact QtJambi has been deprecated a long time ago and the version you are using is a community edition. You should ask the authors of it directly.

  Well, there is nothing wrong about sharing preferences. But it's doesn't matter.
  We are using kubuntu 12.04 and PyQt-4.10.484.4.

  For now, I do windowB.activateWindow() when my mouse enters windowA but it's a bit limited and I don't really like it.

  @SGaist said in Writing directly to the Frame Buffer with PySide/PyQt:

  PyQt5 is either GPL or Commercial, so if you want to make a closed source application with PyQt5 you have to buy a commercial licence from them.

  This project is for an embedded device, which I believe carries its own particular considerations. I've not downloaded anything for the time being, as I need to read up on cross compiling of Qt anyway.

  No it is not. Have you read the documentation carefully? It should look something like:

  Hello @mrjj :

  In my main window, I call to launch my pop-up window :

  The class of my pop-up window is defined as :

  Hello again,

  Finally, I found a solution : putting actions when creating tabs. Here is my code :

  def add_new_tab(self,index,text): new_tab = InterfaceTemplateDialog() self.tabs.addTab(new_tab,text) self.tabs.setTabText(index,text) new_tab.generate_btn.clicked.connect(self.launch) new_tab.run_tranus_btn.clicked.connect(self.run_tranus) new_tab.check_all_btn.clicked.connect(self.check_all) def onChange(self): index = self.tabs.currentIndex() tab_title = self.tabs.tabText(index) tab = self.tabs.currentWidget() if tab_title != "All checked scenarios": scenario = tab_title.split('-')[1] else : scenario ="ALL" return [tab,scenario] def run_tranus(self): tab = self.onChange()[0] scenario = self.onChange()[1] tab.console.append("Beginning of execution of basic TRANUS programs for scenario "+scenario) tab.console.append("Executing loop TRANUS for "+ `tab.spin_box.value()` +" iterations")
