Problem solved with mooving to PyQtGraph. Thanks for help. Vlado import pyqtgraph as pg OUT_Buffer_Time = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26] # 26 spominskih mest OUT_Buffer_Zg = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0] # 26 spominskih mest OUT_Buffer_Sp = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0] # 26 spominskih mest def simple_graph(): H = pg.plot(OUT_Buffer_Time, OUT_Buffer_Zg, pen='b') H.plot(OUT_Buffer_Time, OUT_Buffer_Zg, pen=(255, 0, 0)) H.plot(OUT_Buffer_Time, OUT_Buffer_Sp, pen=(0, 255, 200))

@Technologist Which python and mingw version do you use?

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 : class LaunchTRANUSDialog(QtGui.QDialog, FORM_CLASS): def __init__(self,checked_list,project_directory,tranus_bin_path,parent=None): """Constructor.""" super(LaunchTRANUSDialog, self).__init__(parent) self.setupUi(self) self.project = parent.project self.proj = QgsProject.instance() self.tranus_bin_path = tranus_bin_path self.project_directory = project_directory self.project = parent.project self.checked_list = checked_list self.is_all_checked = False self.tabs = self.findChild(QtGui.QTabWidget, 'tabWidget') self.proj = QgsProject.instance() #control actions self.tabs.blockSignals(True) self.tabs.currentChanged.connect(self.onChange) self.tabs.blockSignals(False) def show(self): self.put_tabs() super(LaunchTRANUSDialog, self).show()

@mrjj no, a callback is just the nomenclature you use to describe functions passed as arguments to other functions to be invoked later.

Hi, QSignalMapper might be what you are looking for.

Hello, It was an other problem that causes this problem. So, I solved and now it works. Thanks .

For more information, here is the error that I get : Couldn't load plugin OptionsTRANUS due to an error when calling its classFactory() method ImportError: cannot import name OptionsTRANUSDialog Traceback (most recent call last): File "C:/OSGEO4~1/apps/qgis/./python\qgis\utils.py", line 333, in startPlugin plugins[packageName] = package.classFactory(iface) File "C:/Users/emna/.qgis2/python/plugins\OptionsTRANUS__init__.py", line 34, in classFactory from .Options_TRANUS import OptionsTRANUS File "C:/OSGEO4~1/apps/qgis/./python\qgis\utils.py", line 607, in _import mod = _builtin_import(name, globals, locals, fromlist, level) File "C:/Users/emna/.qgis2/python/plugins\OptionsTRANUS\Options_TRANUS.py", line 30, in from .OptionsTRANUS_project import OptionsTRANUSProject File "C:/OSGEO4~1/apps/qgis/./python\qgis\utils.py", line 607, in _import mod = _builtin_import(name, globals, locals, fromlist, level) File "C:/Users/emna/.qgis2/python/plugins\OptionsTRANUS\OptionsTRANUS_project.py", line 24, in from .Options_TRANUS_dialog import OptionsTRANUSDialog File "C:/OSGEO4~1/apps/qgis/./python\qgis\utils.py", line 607, in _import mod = _builtin_import(name, globals, locals, fromlist, level) File "C:/Users/emna/.qgis2/python/plugins\OptionsTRANUS\Options_TRANUS_dialog.py", line 29, in from .launch_tranus_dialog import LaunchTRANUSDialog File "C:/OSGEO4~1/apps/qgis/./python\qgis\utils.py", line 607, in _import mod = _builtin_import(name, globals, locals, fromlist, level) File "C:/Users/emna/.qgis2/python/plugins\OptionsTRANUS\launch_tranus_dialog.py", line 7, in from .Options_TRANUS_dialog import OptionsTRANUSDialog ImportError: cannot import name OptionsTRANUSDialog Python version: 2.7.5 (default, May 15 2013, 22:44:16) [MSC v.1500 64 bit (AMD64)] QGIS version: 2.18.3 Las Palmas, 77b8c3d Python Path: C:/OSGEO4~1/apps/qgis/./python C:/Users/emna/.qgis2/python C:/Users/emna/.qgis2/python/plugins C:/OSGEO4~1/apps/qgis/./python/plugins C:\OSGEO4~1\apps\Python27\lib\site-packages\setuptools-0.9.8-py2.7.egg C:\OSGEO4~1\bin\python27.zip C:\OSGEO4~1\apps\Python27\DLLs C:\OSGEO4~1\apps\Python27\lib C:\OSGEO4~1\apps\Python27\lib\plat-win C:\OSGEO4~1\apps\Python27\lib\lib-tk C:\OSGEO4~1\bin C:\OSGEO4~1\apps\Python27 C:\OSGEO4~1\apps\Python27\lib\site-packages C:\OSGEO4~1\apps\Python27\lib\site-packages\jinja2-2.7.2-py2.7.egg C:\OSGEO4~1\apps\Python27\lib\site-packages\markupsafe-0.23-py2.7-win-amd64.egg C:\OSGEO4~1\apps\Python27\lib\site-packages\pytz-2012j-py2.7.egg C:/Users/emna/.qgis2//python

Hay i saw your keyboard its really good, i also want to design this kind of keyboard, can you please tell me when i move the cursor on the keys it automatically enlarge. how is it possible ? and another one is, when i am typing it does not show anything but my only cursor move forward.

Thank you! I didnt noticed that. I did correct this mistakes, but still getting the same error:( and empty window :/

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.

Thanks for this useffull link.

Hi and welcome to devnet, I'd recommend brining this to the PyQt forum. They'll be best to answer packaging related questions. Just in case, I saw the pyqt5-tools package that might be interest. Hope it helps

@jsulm PyQt does indeed deploy to iOS. Acceptance is another issue. But aside from this, my question is really regarding best use of the Qt API for my project.

Model is the QSqlQueryModel of your QTableView

@jsulm Thank you already solve the problem ^_^

@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();

@the_ Thank you ! you help me a lot ! :) GodBless!

I traced the build failure down to pyside commit eb28469e - "Fix QtQuick bindings generation". I haven't had a chance to triage the root cause but pyside builds on macOS up through the previous commit.
