Language Bindings

For more information, here is the error that I get : Couldn't load plugin OptionsTRANUS due to an error when calling its classFactory() method

I've took a look at the official project on SourceForge so we may have something different currently.

For the record, the bug is in PySide. I moved to PyQt and except a few differences, the code is the same. No crash at all.
Sad.

Hi,

First version, you don't want to call find each and every time you want to do something with an internal object.

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

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

Thanks for this useffull link.

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 and welcome to devnet,

Yes, do_work will be called in your thread.

For such a use case, it's a bit overkill, QtConcurrent::run would likely be simpler and cleaner.

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.

@SGaist

DATE_RECEIVED = self.date_received.text()

i stop passing self.date_received.text() to DATE_RECEIVED and i do it in all of my variable

What does " i have problem with touch events" mean in your case?

ps: And please use code tags when posting code

import foo from bar def foobar(): print("this is more readable")

is much easier to read than

import foo from bar

def foobar():
print("this is not readable")

;)

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

@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();

@jsulm Thank you already solve the problem ^_^

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