General and Desktop

I believe it is impossible because those dialogs are native Window' s ones.

@Narki1 said in Few emits in one slot: no one works. What does this means? it crashes? How are you debugging the problem?

Qt now supports 16 bit handling in 5.12 version

@SGaist i'm using arm GNU. And it is for linux platform. ("hisiv100 stands for hisilicon boards).

@SGaist Yes it is, it it works there. Funny enough, it was yet another bug in my code that cause led a zero-width shape.

@SGaist Yes that's correct. Drag would only be triggered when clicking and dragging selected items. If the items are not selected, then no dragging occurs. The selection would be updated instead.

Pseudo code: auto curVal = obj["key1"] auto curArr = curVal.toArray(); curArr.append("c"); obj["key1"] = curArr;

Hi, setInterval just sets the interval while start starts the timer with the given interval. As for your use of sleep, it will block the event loop hence it can't process normally. If you want to introduce different delays you should reconsider your design. Maybe use a state machine.

Hi and welcome to the forums It's hard to guess at with no code. Maybe you assign the same value to all 3 ?

Find out the reason, sqlite version of Qt.511.2 is too old

In my pro file: https://pastebin.com/pbxBNLaR In my output: https://ibb.co/mB4m42B When I add library with this name I see that ITKCommon not found. When I add ITKCommon I see teribble view: https://ibb.co/RypyNnk

@JonB Ooh sorry, I did not see that part. the instruction I was following on qt doc did not mention about make install, it was something like this: cd %QTDIR%\qtbase\src\plugins\sqldrivers qmake nmake sub-odbc And there are two plugin folders But I did this: C:\Qt\Qt5.13.2\5.13.2\mingw73_32>cd C:\Qt\Qt5.13.2\5.13.2\Src\qtbase\src\plugins\sqldrivers\odbc C:\Qt\Qt5.13.2\5.13.2\Src\qtbase\src\plugins\sqldrivers\odbc>mingw32-make install mingw32-make -f Makefile.Release install mingw32-make[1]: Entering directory 'C:/Qt/Qt5.13.2/5.13.2/Src/qtbase/src/plugins/sqldrivers/odbc' g++ -c -fno-keep-inline-dllexport -O2 -std=c++1z -fno-exceptions -Wall -W -Wextra -Wvla -Wdate-time -Wshift-overflow=2 -Wduplicated-cond -Wno-stringop-overflow -DUNICODE -D_UNICODE -DWIN32 -DMINGW_HAS_SECURE_API=1 -DWINVER=0x0601 -D_WIN32_WINNT=0x0601 -DQT_DEPRECATED_WARNINGS -DQT_NO_NARROWING_CONVERSIONS_IN_CONNECT -DQT_NO_CAST_TO_ASCII -DQT_NO_CAST_FROM_ASCII -DQT_NO_EXCEPTIONS -DQT_NO_DEBUG -DQT_PLUGIN -DQT_SQL_LIB -DQT_CORE_LIB -I. -IC:\Qt\Qt5.13.2\5.13.2\mingw73_32\include\QtSql\5.13.2 -IC:\Qt\Qt5.13.2\5.13.2\mingw73_32\include\QtSql\5.13.2\QtSql -IC:\Qt\Qt5.13.2\5.13.2\mingw73_32\include\QtCore\5.13.2 -IC:\Qt\Qt5.13.2\5.13.2\mingw73_32\include\QtCore\5.13.2\QtCore -IC:\Qt\Qt5.13.2\5.13.2\mingw73_32\include -IC:\Qt\Qt5.13.2\5.13.2\mingw73_32\include\QtSql -IC:\Qt\Qt5.13.2\5.13.2\mingw73_32\include\QtCore -I.moc\release -IC:\openssl\include -IC:\Utils\my_sql\mysql-5.7.25-win32\include -IC:\Utils\postgresql\pgsql\include -IC:\Qt\Qt5.13.2\5.13.2\mingw73_32\mkspecs\win32-g++ -o .obj\release\qsql_odbc.o qsql_odbc.cpp g++ -Wl,-s -shared -Wl,-subsystem,windows -Wl,--out-implib,C:\Qt\Qt5.13.2\5.13.2\Src\qtbase\src\plugins\sqldrivers\plugins\sqldrivers\libqsqlodbc.a -o ..\plugins\sqldrivers\qsqlodbc.dll .obj/release/qsql_odbc.o .obj/release/main.o .obj/release/moc_qsql_odbc_p.o -LC:\openssl\lib -LC:\Utils\my_sql\mysql-5.7.25-win32\lib -LC:\Utils\postgresql\pgsql\lib C:\Qt\Qt5.13.2\5.13.2\mingw73_32\lib\libQt5Sql.a C:\Qt\Qt5.13.2\5.13.2\mingw73_32\lib\libQt5Core.a "C:\Program Files (x86)\Windows Kits\10\lib\10.0.17763.0\um\x86\odbc32.lib" .obj\release\qsqlodbc_resource_res.o copy /y ..\plugins\sqldrivers\qsqlodbc.dll C:\Qt\Qt5.13.2\5.13.2\mingw73_32\plugins\sqldrivers\qsqlodbc.dll 1 file(s) copied.

@JonB said in Controls Events: @jenya7 I don't think Qt Creator (I don't use it) provides a drag-and-drop interface to creating one, but yes Qt provides a https://doc.qt.io/qt-5/qfiledialog.html. From code you call one of its methods, you may be able to get away with the https://doc.qt.io/qt-5/qfiledialog.html#static-public-members ones for simplest purposes. Thank you.

Ok, I managed to work around this issue, will write it here in case anybody else has this problem. I quit trying to use qss and did it in the code. Subclassed the QComboBox and added the hover events: bool TrackableComboBox::event(QEvent *event) { switch (event->type()) { case QEvent::Enter: this->setStyleSheet("background-color: rgba(0, 0, 0, 0.2);"); break; case QEvent::Leave: case QEvent::MouseButtonPress: this->setStyleSheet("background-color: -1;"); break; default: break; } return QWidget::event(event); } The secret here is to add Leave and MouseButtonPress reset the color, otherwise you will have the same issue.

@Loic-B You can skip entering your account when installing Qt, then it will be OSS version.
