@FarukErat said in I cannot set QPixmap without passing the whole directory:

I wanna shorten tha path to ":/res/black.bmp".

Then you need to put them into a resource file: https://doc.qt.io/qt-5/resources.html

Hi,

This stack overflow thread might be of interest to avoid having to play with the PATH environment variable.

Are running this on two different computers (or VMs)? It seems there are more variables involved than just 'different version of QtCreator'.

Working:

Qt 5.12.2 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 8.3.0) on "xcb" OS: Ubuntu 19.04 [linux version 5.0.0-38-generic] Environment: QT_ACCESSIBILITY="1" QT_AUTO_SCREEN_SCALE_FACTOR="0"

Not Working (note, QT_ACCESSIBILITY is not set):

Qt 5.12.4 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 9.2.1 20191008) on "xcb" OS: Ubuntu 19.10 [linux version 5.3.0-40-generic] Environment: QT_AUTO_SCREEN_SCALE_FACTOR="0"

Do you have additional KDE packages (not sure what that the 'kdedev' folder is) installed on the one that's working? Does your application depend on them? Can you run it in debugging to see where exactly it is crashing?

@KillerSmath That solved my problem. Thanks!

@Stefan-Monov76 said in How to make Qt Creator use variables in the builddir path, so I can easily rename project?:

Thanks anyway

You're welcome. Shadow building (option 1 from above) should work for you regardless.

@Mark81 ok, I found a way:

QDBusInterface *iface = new QDBusInterface("your.service", "/your/path", "org.freedesktop.DBus.Introspectable", QDBusConnection::systemBus(), this); qDebug() << iface->call("Introspect").arguments();

@Mark81
Hi,

I'm not sure if it is returned from some DBus methods or I have to manually build it using the bluetooth address and the local device.

It is not, you have to handle it manually. From what I can discern from your link it's a path you construct out of device names. If the service is compliant you can usually list the objects it exposes.

Kind regards.

Good !

In that case, please mark the thread as solved using the "Topic Tool" button so that other forum users may know a solution has been found :)

@mrjj said:

"/home/pics/" + name"

Indeed, it worked. Thank you :)

Hii..

Sorry to disturb you but if you are free then please give me answer of below question

https://forum.qt.io/topic/60399/adobe-photoshop-cc-2015-plugin

I am newbie to this Qt framework.

That I can't comment on. You should ask the MySQL people about that matter.

Hi, your env settings for the plugin paths seem a bit fishy, usually the QT_QPA_PLATFORM_PLUGIN_PATH points to a directory one level below QT_PLUGIN_PATH (assuming you're doing a standard deployment of the plugins where libqxcb.so is residing in a subdirectory called platforms).

You could try:
QT_QPA_PLATFORM_PLUGIN_PATH=/usr/local/my_distro/revision/lib/qt/plugins/platforms
QT_PLUGIN_PATH=/usr/local/my_distro/revision/lib/qt/plugins

Also you could try setting the plugin path explicitly in your main.cpp before calling QApplications's ctor, say like this:

... QCoreApplication::setLibraryPaths("/usr/local/my_distro/revision/lib/qt/plugins"); QApplication a(argc, argv); ...

This will override env settings for the plugin paths.

To debug when the bad 5.15.0 dlls/plugins are pulled in, open a Terminal and type "lsof -c yourappname" to see what dlls are loaded.

@reina
Could you provide us with a usecase? In my experience, a QPixmap only interacts with file storage at initialization and is then a blob of data with an API for internal use.

@Carsten-Hansen ":/" is the root path of the Qt Resource System.

Resource files are built into your .exe, so you don't need to supply the individual files.

Is it an error from a self built Qt ?
