https://www.linkedin.com/in/sujan-d-6a980151/ This is my Linked In profile. Let me know if visa sponsor is available with you ? I am interested but I am Indian, if you sponsor me work visa, I will be able to move.

@hfinger said in How to fix installer file while installing: @sierdzio Do you mean something like /home/.qt5/? (This is Ubuntu.) Or something like /home/myhome/.qt5/? Note sure what you mean by local directory. I am a newbie. I usually install to /home/username/qt.

@rohit1729 You should read this first: https://doc.qt.io/qt-5/signalsandslots.html void panelB::mouseMoveEvent(QMouseEvent *eventMove) { QString txt; txt = QString("(X:%1,Y:%2)").arg(eventMove->pos().x()).arg(eventMove->pos().y()); emit coordinatesChanged(eventMove->pos().x(), eventMove->pos().y()); //qDebug() << txt; } coordinatesChanged would be the signal.

This is my experience with "Ravi, Robbie" and whoever is running things at goslicd. I interviewed over a skype call and in my oppinion it went very smoothly and it was a good interview. He knows I'm at least qualified if not over qualified for this job. He said over skype that he would send me the coder agreement that I could read over and then get back to him on it. He never sent the agreement. It's been 2-3 days. It was supposed to be sent right after the skype call. No email from him. I sent an email asking about it. No response was returned. I said I was open about how much I would get paid per milestone. That would be an employer's wet dream, right? There is no hourly wage, it's jut pay-by-milestone + equity (so they say). Another horror story from the dishonest, fake, unfair job market. This post has no business in the Qt forums, with such disrespect shown from the hiring party. Well, they do have about a 20% chance of success as 80% of startups fail. Good luck to them! I could have finished all of the project milestones in less than half the timeline stated. Their loss. Thinking of applying? Don't waste your time.

@Gojir4 thanks, I am trying that right now. I’ve added a 1s delay in my image grabbing thread. Let’s see. Fingers crossed!

@JKSH That makes sense. I'll give that a try. Thanks again!

@Eoin what about work visa, will you take care of it.?

I've managed to figure out the issue. It turns out that I needed to disable power management signalling (dpms). I added the following lines to my /home/pi/.config/lxsession/LXDE-pi/autostart file - @xset s off @xset -dpms @xset s noblank The GUI now remains fully responsive even after a full day of running. Thank you for your time @SGaist

@Andrex_Qt said in Responsive QtMainWindow on Startup.: i access them through C Api Could it be possible you share a link to such API for the benefit of other users just in case?

Hi, Thank you for your reply. I totally changed my implementation using the signal and slots. Thank you so much again.

@kenchan I want to draw it on QOpenGLWidget and i want to relate it to an audio file so i can position it wherever i want

@HW-Developer Start here http://doc.qt.io/qt-5/qtxml-index.html

@sebs What I don't understand: you want an application with 3 threads, right? But why do you create new process?

Hi and welcome to devnet, Can you show the code you are using ? What exactly do you expect ? What exactly do you get ?

Everything is correct. I have reinstalled and these three buttons are done by as you already stated. Thanks! It was two reasons. THANKS!!!

@JKSH Yes, I had to reinstalled QT on Visual C++. Works OK... THANKS!!!

@Christian-Ehrlicher ahh, you are right. Good catch. http://doc.qt.io/qt-5/qjsonvalue.html#toDouble converts the QJsonValue to double if its that type(). in this case it will return defaultValue (0) so its something like QJsonValue bid1 = jsonObj.value("bid_1"); QString asStr=bid1.toString(); double n = asStr.toDouble(); qDebug() << n;

Hi and welcome to devnet, There's no ready made "console widget", you can use QPlainTextEdit or depending on the amount of data a QListView with a custom QStyledItemDelegate for fancy rendering. For getting the output of your cli application, you can use QProcess.

Hi You did read ? http://doc.qt.io/qt-5/stylesheet-examples.html#customizing-qscrollbar

@GhostWolf Sounds like it crash. Does the samples also crash ?

@jsulm Oh. I haven't considered that. I'm definitely going to try that. I don't know why it didn't came to my mind. Thank you very much. I really appreciate your advice. I have been stuck at this problem for a week. I am glad there are people who are willing to help beginners.

@moffa13 said in Slot called multiple times to a blocking function in the same thread: One question : Is it bad to lock and unlock a mutex multiple times ? No, that's exactly what they are deigned for

Hi, sadly, I do not now. It looks like it can be a pain to integrate OpenGL with qtquick2, but it is possible. Widget-base approach is much more straightforward, but you loose "qtquickness" :P Sorry for the delay, I had a long brake from work.

Here is a possible solution for solving this "missing check/mark" issue. I implemented the CSS "indicator" solution I got from this qt form post which is problematic. Sources of solution: Doc page: here Implementation: here QPalette p = ui->checkBox->palette(); p.setColor(QPalette::Active, QPalette::Base, QColor(255, 255, 255)); p.setColor(QPalette::Button, QColor(255, 255, 255)); ui->checkBox->setAutoFillBackground(true); ui->checkBox->setPalette(p); QColor(255, 255, 255) refers to your desired background color, possibly the same color as your window background, etc. QPallete::Active, QPalette::base refers to the active checkbox's background (the white box background) QPalette::Button refers to the "actual background" (behind the checkbox and the checkbox text) Hope this helps!

@Onikouzou What is this checkbox used for? If you only want to use a combobox then do: QInputDialog showSounds; QStringList soundList; soundList << "Sound 1" << "Sound 2"; showSounds.setOptions(QInputDialog::UseListViewForComboBoxItems); // Remove this if you want a combobox instead of a list showSounds.setComboBoxItems(soundList); showSounds.setWindowTitle("Select sounds"); showSounds.exec();

Anreads I sent you my CV I am Sujan from India, if you give work visa I can relocate

@SGaist Thank you, I will try it!

@raven-worx Thank you for pointing me to the proper documentation pages – I'll have a look at them asap. If the project actually takes off, I'll be a regular in the forums :-) Best regards, – Davide

if instead of checking the property you use the pseudo-state it should work qwidget->setStyleSheet( "QWidget:disabled{color: #64B2D1;}" "QWidget{color: blue;}");

Hey @Wieland . Thanks for the help . It is working fine . ( i will customize it now to my needs )

Actually, my idea is to have a storage of different wooden blocks in user interface and drag them one-by-one to working area to design a house model and then generate a txt file containing the stream of the coordinates (including some other attributes like color, shape) of building blocks.

@Wieland, this float number is represent the speed Value of DC motor in RPM, may you mean I it should be in double type or something else!!. in fact I don't know obviously whit's the type I should use this is the GUI I built link text you can see in Stack-overflow here: link text may you get what I need, I'am sory to be annoying but I spent alot of time in this problem :(

By the way, in QApplication's detailed documentation, you have an example of how start an application in "no-gui" mode.

Understood. Thank you.

Then you should take a look at this to get started. See also Qt::AA_EnableHighDpiScaling in Qt's Application Attributes enumeration
