General and Desktop

I just found out that if I copy the two enums from the DeckLinkAPI.h file and put them in a new file ( only the enums ) and include that file like this #pragma once #include <QObject> namespace DLink { Q_NAMESPACE // #include "DeckLinkAPI.h" #include "DeckLinkEnumWrapper.h" Q_ENUM_NS( _BMDDisplayMode); Q_ENUM_NS( _BMDPixelFormat); }; and then everything compiles and works. I guess the DeckLinkAPI.h file has something that prevents a successful compilation, since this is an external file I don't know how to solve it other than what I did above, any one have an idea?

Thanks guys @jsulm & @mpergand it works now! i've been using a wrong bitratebox.h bitratebox.cpp files now i take the right ones from the site : [image: 17053271-209f-4e8d-a82e-be7336647858.png]

@ChrisW67 Where I added the comments with the offending code. I had to set the parents of some of the objects because it actually did not cleanup when the objects were destroyed, contrary to expectations. One of the error was on me because my game class wasn't properly destructed (and isn't a Qt object).

@yldzmuhammed quite literally like I wrote earlier. for example I have a batch file to connect network drives the the windows explorer. That is located on my desktop. So I add QMAKE_POST_LINK += CMD /c CALL "C:\Users\jhilk\Desktop\Connect_Network_Drives.cmd" anywhere in my pro file: QT += core gui greaterThan(QT_MAJOR_VERSION, 4): QT += widgets CONFIG += c++11 # You can make your code fail to compile if it uses deprecated APIs. # In order to do so, uncomment the following line. #DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0 SOURCES += \ main.cpp \ mainwindow.cpp HEADERS += \ mainwindow.h FORMS += \ mainwindow.ui QMAKE_POST_LINK += CMD /c CALL "C:\Users\jhilk\Desktop\Connect_Network_Drives.cmd" # Default rules for deployment. qnx: target.path = /tmp/$${TARGET}/bin else: unix:!android: target.path = /opt/$${TARGET}/bin !isEmpty(target.path): INSTALLS += target and once each rebuild, that batch file is executed.

@oncewealthy Hello and welcome. I don't know what your issue is, but for sure it has nothing to do with the setStyleSheet() that this topic is about. Please open your own new topic if you have questions about linking.

@SimonSchroeder I think I now have the solution. My problem was: Running CMake in project libzip, issues errors that make it look as though the user needs to set path type variables, ZLIB_LIBRARY and ZLIB_LIBRARY_DIR. If you set these variables to a path like I did, you then get the errors "cannot find...permission denied"etc. The libzip CMake file has , find package ZLIB. I didnt notice that findZLIB.cmake is actually a CMake file that is installed in the Qt directories i.e. in my case, not provided by the github clone in my root project! c:/Qt/Tools/CMake^4/share/cmake-3.23/Modules FindZLIB.cmake tells you: Distributed under the OSI-approved BSD 3-Clause License. See accompanying file Copyright.txt or https://cmake.org/licensing for details. #[=======================================================================[.rst: FindZLIB Find the native ZLIB includes and library. IMPORTED Targets ^^^^^^^^^^^^^^^^ .. versionadded:: 3.1 This module defines :prop_tgt:IMPORTED target ZLIB::ZLIB, if ZLIB has been found. Result Variables ^^^^^^^^^^^^^^^^ This module defines the following variables: :: ZLIB_INCLUDE_DIRS - where to find zlib.h, etc. ZLIB_LIBRARIES - List of libraries when using zlib. ZLIB_FOUND - True if zlib found. :: ZLIB_VERSION_STRING - The version of zlib found (x.y.z) ZLIB_VERSION_MAJOR - The major version of zlib ZLIB_VERSION_MINOR - The minor version of zlib ZLIB_VERSION_PATCH - The patch version of zlib ZLIB_VERSION_TWEAK - The tweak version of zlib .. versionadded:: 3.4 Debug and Release variants are found separately. Backward Compatibility ^^^^^^^^^^^^^^^^^^^^^^ The following variable are provided for backward compatibility :: ZLIB_MAJOR_VERSION - The major version of zlib ZLIB_MINOR_VERSION - The minor version of zlib ZLIB_PATCH_VERSION - The patch version of zlib Hints ^^^^^ A user may set ZLIB_ROOT to a zlib installation root to tell this module where to look. Once you set ZLIB_ROOT to the path where you have the dependencies (.dll and headers) (I set it to D:/ctest) then the CMake parses find and then you can successfully build.

I think this is possibly a bug of Qt and have filed a report at https://bugreports.qt.io/browse/QTBUG-105231.

I modify the code as your suggestion,it works well,thanks a lot

The trick of the mouse to rotate is that the rendering is rotated independently from the item itself. As for the movement, unless I am mistaken, it's always moving "horizontally" with respect to the item rotation rotation. Much like when you are walking, you are going forward, when you rotate you still go forward but with a different angle than before.

Thank you, I will check it!

Under Qt 5.12.11, the bug does not exist. So I took a look at the QAbstractScrollArea::sizeHint code of this version and compared it with the implementation used in recent versions of Qt and found that setting verticalScrollBarPolicy to "ScrollBarAlwaysOff" the "AdjustToContents" adjustment policy works. The default value was "ScrollBarAsNeeded", in fact we can see that this value is not handled but since in Qt 5.12.11 we only compare the vertical|horizontal]scrollBarPolicy to Qt::ScrollBarAlwaysOn it prevents this bug from appearing. The version used in the Qt github master branch : QSize QAbstractScrollArea::sizeHint() const { Q_D(const QAbstractScrollArea); if (d->sizeAdjustPolicy == QAbstractScrollArea::AdjustIgnored) return QSize(256, 192); if (!d->sizeHint.isValid() || d->sizeAdjustPolicy == QAbstractScrollArea::AdjustToContents) { const int f = 2 * d->frameWidth; const QSize frame( f, f ); const bool vbarHidden = d->vbar->isHidden() || d->vbarpolicy == Qt::ScrollBarAlwaysOff; const bool hbarHidden = d->hbar->isHidden() || d->hbarpolicy == Qt::ScrollBarAlwaysOff; const QSize scrollbars(vbarHidden ? 0 : d->vbar->sizeHint().width(), hbarHidden ? 0 : d->hbar->sizeHint().height()); d->sizeHint = frame + scrollbars + viewportSizeHint(); } return d->sizeHint; } The version used in Qt 5.12.11 : QSize QAbstractScrollArea::sizeHint() const { Q_D(const QAbstractScrollArea); if (d->sizeAdjustPolicy == QAbstractScrollArea::AdjustIgnored) return QSize(256, 192); if (!d->sizeHint.isValid() || d->sizeAdjustPolicy == QAbstractScrollArea::AdjustToContents) { const int f = 2 * d->frameWidth; const QSize frame( f, f ); const QSize scrollbars(d->vbarpolicy == Qt::ScrollBarAlwaysOn ? d->vbar->sizeHint().width() : 0, d->hbarpolicy == Qt::ScrollBarAlwaysOn ? d->hbar->sizeHint().height() : 0); d->sizeHint = frame + scrollbars + viewportSizeHint(); } return d->sizeHint; } Can someone update the status of this ticket : https://bugreports.qt.io/browse/QTBUG-101874 in any case, this method must be rewritten and it may not be obvious to handle the "ScrollBarAsNeeded" case at first glance

Thanks @mpergand i'm gonna try to implement this example CAN Bus example | Qt Serial Bus 5.15.2 (https://code.qt.io/cgit/qt/qtserialbus.git/tree/examples/serialbus/can?h=5.15.2) i hope it works

@embeddedmz_2 said in Infinite wait when stopping QThread event loop and then calling wait: if your program behaves differently from one version of Qt to another, it is a bug in Qt. Not necesserily...

I tried taking the current html of the editor and and adding markdown code to it and set the new string to the editor as markdown. Something like the following: editor.setMarkdown(self.ed.toMarkdown() + "- [ ] check") This works as intended but obviously, processing the whole string every time you need check box is not efficient.

@JKSH said in No suitable kits found / Invalid Qt Version: Hover over the yellow exclamation marks in the "Kits" tab then. What do you see now? Oh, in this case I see that there are some warnings: Warning: No debugger set up Warning: CMake tools is unconfigured, CMake generator will be ignored Warning: CMake configuration has a path with qmake binary set, even though the kit has no valid Qt version Debugger: Not recognized engine using: .../Qt/Tools/mingw1120_64/bin/gdb.exe

Great ! Then please mark the thread as solved using the "Topic Tools" button or the three dotted menu beside the answer that you deem correct so that other forum users may know a solution has been found :-)

Hi, That's an OpenCV question and you should bring that to their forum. What your code does not show is how you manage that box variable and whether its content changes between your cv::line calls.

setTickType, setTickAnchor, setTickInterval, setTickCount... Examine and use these assignments. I can say that you will achieve the result by adjusting the values ​​you want in each chart renewal.
