Qt 6

Hi,

For version less support in cmake see the dedicated chapter in Qt 6's documentation.

As for the differences, there is the porting guide.

Thanks a lot! now I understand well why it was that of L and l. Try that and it works!

@appdev said in [Timestamp interpolation]:

To be more specific, is there any function in Qt that can interpolate QDateTime.

No but why should such a thing exist?

Convert your strings to QDateTime and calc the difference.

Hello and welcome.

In addition to @mchinand, please think about a (short but) meaningful title for your threads. hey, does not help those who read the questions.

You probably will also need to paste the content of your game.h header file, we need to see the declaration of Game class (does it have Q_OBJECT macro?) and Game::spawnEnemy() method (is it marked as a slot?).

Hi,

Thank you, that works.

Regards,

Michal

I guess it depends of what you are using from OpenGL and GLSL.

The opengl32sw.dll (mesa3d llvmpipe) that Qt is using is a bit dated, and might not provide the OpenGL version that you need.

You can get a newer version from https://github.com/pal1000/mesa-dist-win

Hi.

Qt6HostInfoConfig.cmake should be found in the host (read desktop) Qt installation.

You should not create the file yourself, but rather specify a -DQT_HOST_PATH=/path/to/host/qt argument when configuring the Qt for raspberry Pi, to a prebuilt / installed host Qt (for example, the one that comes with your distro, or the one from the Qt installer)

Hi,

Same answer as here.

@JonB It is a meson project using custom commands, and QT will not let me specify a different executable for release and debug. It will only let me manually switch which executable it will run, so I can have build run the debug build and then run run the release executable which is something I do not want done.

I tested the build with the sources but on a more recent version of macOS and it went fine using the same options as you.

QtXlsx is pretty limited in what it supports. There are many features of Excel which it does not support, including maybe your "groupRows".

This is because of virtualbox 3d acceleration support opengl version 2.0
it looks like qt multimedia(6.2) need opengl at least 3.0 version

Below was how to know it.
mesa log enable and log like below

Mesa: glGenTextures 1
Mesa: glBindTexture GL_TEXTURE_2D 2
Mesa: FLUSH_VERTICES in bind_texture_object
Mesa: FLUSH_VERTICES in teximage
Mesa: glTexImage2D GL_TEXTURE_2D 0 GL_R8 960 360 1 0 GL_RED GL_UNSIGNED_BYTE (nil)
Mesa debug output: GL_INVALID_VALUE in glTexImage2D(internalFormat=GL_R8)

GL_R8 variable is available upper than opengl 3.0

That's why we have to see green screen in virtualbox 3d acceleration

@JKSH Thank you ! I didn't know that, it's way more convenient

@Patsch36 said in QSqlDatabase: QMYSQL driver not loaded:

How can be the driver now available but does still not work?

Set QT_DEBUG_PLUGINS environment variable before starting your app, then post the output from terminal here.

Also, exact same questions is asked many many times, please search in this forum.

@Joona-A said in Allocation of incomplete type 'QaudioOutput':

What's wrong?

You forgot to include QAudioOutput header file as shown here: https://doc.qt.io/qt-5/qaudiooutput.html ?
