@lukutis222 And it is better to pass your vector as const reference. I guess you do not want to make a copy of it. float calculate_1_min_average(uint32_t sample_counter, uint8_t index_1_min, const std::vector< float > & average_vector){

@Robert-M said in SIGSEGV in fromStdString: other_options If other_options is your struct with your data, you want to send to your dialog, it's fine. Nobody said it's not :) The QVector would make it more variable

@JonB Thanks for help, I solved it, I called other method in my constructor and it was blocking everything.

@nicker-player As @jsulm says. The order is undefined and that is how Qt QJson... sorts output. If you search this forum there have been several long discussions about this a while ago. One of them elected to use some third-party library to do their desired JSON output sorting. I cannot recall what that was, whether it was Python, whether it's available to you....

@Damian7546 QList<QByteArray> QByteArray::split(char sep) const with . as splitter. You might alternatively convert to a QString, pass it to QUrl and use its methods to parse the IP address into segments for you.

@kshegunov Hard to believe this issue been around since 2015. This is good reading but I didint manage to solve my problem. I use different methods of drawing graph than they are discussing. I am very new to QCustomPlot and C++ in general so the whole overriding virtual function thing is still complex to me. Hoping that someone who had simillar issues before with this can give me some additional help here. Thanks

@Dummie1138 Well, adding/deleting items will also likely trigger a "selection changed". Check QList<QTableWidgetItem *> QTableWidget::selectedItems() const for what is now selected, maybe it's the same items as before, maybe all selections get cleared on changing items....

Hi @JoeCFD, Thanks, your idea is working. I have iterated through all the pixels and I have ignored the background color pixels. While iterating through the image, I have incremented the RGB channel data values to apply gradient inside the icon.

@jsulm thank you

@trusktr With property bindings in C++ the answer is easy: the inspiration were property bindings from QML :-) They came first (around 2007, back in Qt 4.7 days). And with QML I think the inspiration was just in the nature of this (by then) new language: QML is a declarative language so you need a mechanism to automatically update values when their components change. And since Qt had signals and slots since early days (early '90), it was quite straightforward to implement this using existing "backend" technology.

@masa4 Looks like another Qt version was installed (looks like 32bit) in /lib. So now, if you start QtCreator the loader finds Qt libraries in /lib which cannot be used with QtCreator as it was linked against Qt libs in /usr/lib64.

@Dsig Are you using PySide or PyQt? What "box"? AFAIK PyUic is a tool that comes with PyQt

@SGaist said in QMenu And QSqlQueryModel translation problem !: QEvent::LanguageChange @ SGaist Hi bro <3 i didn't know about QEvent::LanguageChange before really thank you, i will check it <3

@ArtiFAS That's one of the issue with the code sample you gave. There's not enough context to fully understand how it is working. Now the question is: why do you need a separate thread to handle your network connection ? Most of the time there's no need for that as Qt is asynchronous.

@Pl45m4 Thank you. Documentation for Python : https://doc.qt.io/qtforpython-5/PySide2/QtGui/QPixmap.html Example of code : I give this because of the minimum examples on the internet from PyQt6.QtCore import Qt ... self.labelCropFace.setPixmap(pixmap3.scaled(self.labelCropFace.size(), Qt.AspectRatioMode.KeepAspectRatio)) For other people who need it, hopefully it helps too

@ocgltd It is totally up to you how to build shared libs, like which classes are added to .so. Qt can not automatically detect what is included in the lib. But when Qt code uses any of classes which are supposed to be in the lib, they should be there. Otherwise, you will see errors like undefined symbols.
