@Vijaykarthikeyan I uninstalled and reinstalled the compilers..now it is working..But,it is important to learn about configuring the Qt projects

@JoeCFD QML file code below. I haven't edited it at all. QT += quick CONFIG += c++11 # The following define makes your compiler emit warnings if you use # any Qt feature that has been marked deprecated (the exact warnings # depend on your compiler). Refer to the documentation for the # deprecated API to know how to port your code away from it. DEFINES += QT_DEPRECATED_WARNINGS # You can also make your code fail to compile if it uses deprecated APIs. # In order to do so, uncomment the following line. # You can also select to disable deprecated APIs only up to a certain version of Qt. #DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0 SOURCES += \ main.cpp RESOURCES += qml.qrc # Additional import path used to resolve QML modules in Qt Creator's code model QML_IMPORT_PATH = # Additional import path used to resolve QML modules just for Qt Quick Designer QML_DESIGNER_IMPORT_PATH = # Default rules for deployment. qnx: target.path = /tmp/$${TARGET}/bin else: unix:!android: target.path = /opt/$${TARGET}/bin !isEmpty(target.path): INSTALLS += target

Here is a final version on how to solve this related matter. Ensure that you have set your system path for mysql. SET PATH=%PATH%;[mysql/bin] In your cmakelist, link mysql library to project set(MYSQL_DIR "C:/Program Files/MySQL/MySQL Server 8.0") set(MYSQL_INCLUDE_DIR "${MYSQL_DIR}/include") find_library(MYSQL_LIBRARY NAMES mysql PATHS ${MYSQL_DIR}/lib ) target_link_libraries(target ${MYSQL_LIBRARY} ) If you like to deploy the project to other pc, please ensure that you have included necessary file needed for mysql. For my case, the mysql version I'm using is MySQL Server 8.0. What I need to do was copy libcrypto-3-x64.dll, libssl-3-x64.dll and libmysql.dll to my project directory. Here a cmakelist version of copy the dlls needed. set(MYSQL_REQUIRED_FILES "${MYSQL_DIR}/bin/libcrypto-3-x64.dll" "${MYSQL_DIR}/bin/libssl-3-x64.dll" "${MYSQL_DIR}/lib/libmysql.dll" ) foreach(SOURCE_FILE IN LISTS MYSQL_REQUIRED_FILES) get_filename_component(FILE_NAME ${SOURCE_FILE} NAME) add_custom_command (TARGET appManualEDI POST_BUILD COMMAND ${CMAKE_COMMAND} -E copy ${SOURCE_FILE} ${CMAKE_BINARY_DIR}/${FILE_NAME} COMMENT "Copying ${FILE_NAME} to ${CMAKE_BINARY_DIR}" ) endforeach()

@jsulm QML was not installed, I installed it in the Software Manager (LM21.2) but KDevelop still shows the <QQmlApplicationEngine> file is not found. There is a huge number of QML installs in the Software Manager but I didn't see any that mentioned header files for QML.

@JonB Yes, you are correct. Unlike QPdfWriter, QPixmap must be big enough for the image that is to be drawn. Thanks!

Hi, I haven't tested it yet but this Qt blog article might be what you are looking for.

@SGaist Thanks for your reply. The random crash may be caused by corrupt memory. Will use valgrind to check the code out.

@Rumeysa_135 said in QTimer: but I cannot do this on the 2nd page. The pages should only be a representation of your data. You still retrieve the data every 2 seconds and display the data you want to show on page/widget 1 and 2 respectively.

Try to add Qt::Window to setParent as here: mAssistant = new ManualAssistant(); mAssistant->setModal(true); mAssistant->setParent(parent, Qt::Window); mAssistant->exec();

@obelisk79 Difficult to make guesses in the dark: Which Qt Version & platform is used here? How are the icons populated? Anything special about their size? Can you show the relevant code?

You have to add your widget to the parents layout.

@Radio1985 said in QT Desktop Database Application and Remote Connection: When you say a database server did you mean a cloud base database? You wrote: "the data stored in the database should be able to access from a different location and different network". That means that you need a server which can be accessed from all locations where the access is required. Whether it is a traditional database server or cloud is again something you need to decide. Cloud would require less maintenance on your side I guess, but then you have to trust the cloud provider. If your data has a well defined structure and you need the possibility to query it then I would recommend SQL.

@jsulm @JonB , Thanks for the suggestions. Yeah I was able to learn from ui_...h file how things are implemented. I removed all the alignments in the first row. Then I set my dynamic widget parameter dimensions and alignment according to the first row. Thanks!

@KAMblLLl said in The text drawn by paint scrolls with the scroll bar: There are some text elements that must have highlighted word inside You could also use https://doc.qt.io/qt-6/qsyntaxhighlighter.html

You can simply iterate your vector and then do the connections you want on the current object in the iteration loop.

Hi, A single qmake ? No, a single .pro file ? Yes, check the ones generated by Qt Creator. There's a test to check whether you are using Qt 4 or Qt 5 (or at least there was)

Hi try https://github.com/QtExcel/QXlsx

That's currently the only way: https://wiki.qt.io/Center_a_QCheckBox_or_Decoration_in_an_Itemview
