opencv is one way

@jsulm said in Qt 5.15.2 MinGW 32-bit throwing errors but 64-bit version working fine.: If you do not have such customers I am hoping I don't. Thank you for your insight.

@AnneRanch said in How to use __LINE__ macro as QString parameter ?: QString label = QString(LINE ); //current code line use QString::number QString label = QString::number(__LINE__ );

QPixmapCache can be a good start.

The search for LSP (language server protocol). The Kate editor has a plugin for KTextEditor.

A QDialog is not meant to be used inside another widget. It's a top-level widget and there is no need / usecase for it.

@Christian-Ehrlicher said: msvc doesn't know the concept of 'system headers'. It does. It just calls them "external headers", which is IMO a better name for it, as there is nothing system about Qt on Windows for example. @Taytoo If you want to skip all compilation warnings from, say C:\Qt\Qt5.12.2, you can do it like this: /experimental:external /external:W0 /external:I C:\Qt\Qt5.12.2 The first switch enables this feature (it's experimental). The second one sets the warning level for external headers (W0 disables them entirely) and the third one sets a path to treat as external. But that's really not the problem. The question was about the static code analysis tool and those switches unfortunately won't work with that. VS static analysis tool does not have warning levels so there's no switches to configure it. The current solution MS suggest for that is something like this: #include <codeanalysis\warnings.h> #pragma warning( push ) #pragma warning ( disable : ALL_CODE_ANALYSIS_WARNINGS ) #include <Qt includes you use> #pragma warning( pop ) which, admittedly, is quite ugly and invasive. It also has a nasty side effect of silencing everything that gets included transitively from Qt, so make sure Qt headers are last on your include list. UPDATE: There have been improvements to this and now external code can be excluded also from code analysis. See this blog post for details: Customized Warning Levels and Code Analysis for External Headers

@djsuson Hi, I'd send a signal from your dialog to be handled where needed to open the data.

@suslucoder said in Table Widget selected item doesnt take the first one: But it doesnt take the first one that i select Yes, this code will visit all selected items, including whatever "first one" which you say it does not include. Else everybody would be complaining about it. Why don't you print out: qDebug() << ui->tableWidget->selectedItems().length();

@suslucoder And where does the code you show generate but it says me series[1] doesnt declare in this scope ? Where is the for loop you say you are trying? Also, where does it use the QLineSeries *series[7]; you say you are having trouble with? I do not see it using any array of anything, which is what your whole question is about...

How to make QComboBox or QCheckBox delegates show constantly? They appear when I clicking on the cell only. Or this approach (QTreeView + custom delegates) is not suitable for my case?

Thank you to all the panellists, I’ll take care of it. Can we leave it open in case there are any mistakes or questions?

@developer_61 said in QFileSystemWatcher sends 2 signals. Is there anyway to avoid that?: i think its solved. so don't forget to mark your post as such!

@suslucoder Was this code executed at all? How is it triggered? Please provide more information when asking!

@Sakasushi as @JonB already has written, you are mixing up MySQL/MariaDB and phpMyAdmin: MySQL/MariaDB are database engines phpMyAdmin is a database administration tool If you want to use QSqlDatabase/QSqlQuery/etc., you have to connect to the db engine.
