  Yes it does.

  How can we translate the string which contains \n during the string translation also.

  Just include \n in the translated text :-) If it is needed in other language, of course.

  Because you are using lang="it" this means that the file is only available if your locale is Italian. See the resources chapter in Qt's documentation for a more thorough explanation.

  Hello @mrjj :

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

  def show(self): self.project.load() if self.project.tranus_project: self.tranus_folder.setText(self.project.tranus_project.path) self.activate_launch_button() self.launch_options_TRANUS() super(OptionsTRANUSDialog, self).show() ...... def launch_options_TRANUS(self): self.get_checked_list() if self.checked_list != [] : dialog = launch_tranus_dialog.LaunchTRANUSDialog(self.checked_list,self.folder,self.tranus_binaries,parent=self) dialog.show() result = dialog.exec_() self.reinitialise_checked_list()

  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")

  By the way, why not use super rather than call the base class __init__ ?

  Hi,

  No special suggestions, the goal of both is to provide a complete set of bindings for the Qt modules.

  PySide2 information can be found here. If you need to start right now with Qt 5 and python, PyQt might be the current best option.

  I haven't tested Python for mobile application so I can't comment on that however there might be catches with the mobile platform development rules about using an interpreter that you should check.

  Hi,

  Putting your stylesheet at the application level (especially if the one your wrote) means that each and every widget might be customised which requires changing the style used to draw the widget. So you should be careful with what you put in your stylesheet.

  ps: And please use code tags when posting code

  is much easier to read than

  @Gelo said in Whats wrong with my code!:

  self.query = QSqlQuery() self.query.prepare("SELECT username FROM users WHERE username = '%s' and password = '%s'"%(USERNAME,str(PASSWORD))) self.query.addBindValue(USERNAME) self.query.addBindValue(PASSWORD)

  I just wonder this works... did you read http://pyqt.sourceforge.net/Docs/PyQt4/qsqlquery.html for how to use prepare statement and binding values?

  To bind values to a prepared statement you need placeholders.
  According to the examples on http://pyqt.sourceforge.net/Docs/PyQt4/qsqlquery.html it should be done like this:

  Named binding using named placeholders:

  QSqlQuery query; query.prepare("INSERT INTO person (id, forename, surname) " "VALUES (:id, :forename, :surname)"); query.bindValue(":id", 1001); query.bindValue(":forename", "Bart"); query.bindValue(":surname", "Simpson"); query.exec();

  Positional binding using named placeholders:

  QSqlQuery query; query.prepare("INSERT INTO person (id, forename, surname) " "VALUES (:id, :forename, :surname)"); query.bindValue(0, 1001); query.bindValue(1, "Bart"); query.bindValue(2, "Simpson"); query.exec();

  Binding values using positional placeholders (version 1):

  QSqlQuery query; query.prepare("INSERT INTO person (id, forename, surname) " "VALUES (?, ?, ?)"); query.bindValue(0, 1001); query.bindValue(1, "Bart"); query.bindValue(2, "Simpson"); query.exec();

  Binding values using positional placeholders (version 2):

  QSqlQuery query; query.prepare("INSERT INTO person (id, forename, surname) " "VALUES (?, ?, ?)"); query.addBindValue(1001); query.addBindValue("Bart"); query.addBindValue("Simpson"); query.exec();
