I have seen the original question qt-creator-how-to-set-application-icon
but it did not help me because i am building an app in ubuntu and the Qt`s Documentation
is not clear for me..
Is there anynone, who has done it?
Whats the method?
Thanks in advance.
Linux does not have any standard for reading embedded resources, so there is no way to embed the icon in the application binary itself and have it display in the menu and launcher. You will have to install your icon in the appropriate pixmaps directory and a .desktop file in appropriate apps directory pointing to your application and respective icon.
The Qt documentation you quoted refers to icon theme specification, which describes where the files should be installed. Look for the Installing Application Icons towards the end for summary of what needs to be done.
You will have to install the files in the "install" target of your build system (qmake or cmake or what you use) and possibly create a Debian package on top of that. The Qt Creator is unlikely to help you with these.

I have a project written in Qt that I have no problems compiling and running on Linux. The command line is:
qmake ../trunk/GSDTesting.pro
The process on Linux was really simple: install a few dependencies using apt and you are off.
My task is to recompile the same program on Windows using Visual Studio C++ compiler, but the problem is I don't know how to start. There is no such thing as qmake for Windows.
Can someone give me a few hints where to start. Please note that I don't know QT almost at all, my task is just to debug some issue unrelated to QT.
Are you using terminal exclusively on Windows? If so, maybe this image of example build steps straight from Qt Creater 4.14.2 may help you:
As you can see the image of the default Qt creator build steps list the file path where 'qmake.exe' can be located on a local installation of the toolchain.
If you can use a machine with a display I find using the Qt creator GUI is not all that bad.
Here is a link to the base get started page:
https://doc.qt.io/qt-5/gettingstarted.html
Here is a link to the installer download page:
https://www.qt.io/download
IMPORTANT:
You will need to make a Qt account, login to your account, and then download the open-source version of the API. The commercial version of the same source is acquired differently/seperately.
Otherwise, if you cannot use the GUI, can I request some clarification on why you cannot use Qt creator on your Windows installation?
I would like to use heob to check my app for memory leaks. This is what i tried: I opened the project "analogclock" from the examples collection in qtcreator. After that i have chosen "Analyze" and "Heob" from the drop down menu. After choosing the heob path and a click on the ok button, the application starts and a console window "heob32" is displayed. But now nothing happens. Just the word "kill" is displayed in the console window. I can´t see any output and if i close the analogclock app i get the message: "heob: cannot create target process". Can anyone help me further to get useful output from heob?
What OS are you using and what heob did you install?
You need to download and install heob separately from Creator. Creator just installs a link without heob itself. Have you done this? Are you really running on a 32-bit system (there is a heob64 in case you are using a modern OS).
Did you configure your heob installation in Qt Creator correctly?
Can you run heob from the commandline with reasonable behaviour?
I am using Visual Studio 2019 on Windows 10 and am trying to use GTK in C++ and installed it using vcpkg.
I've installed GTK using vcpkg according to the guide from GTK. I'm using Visual Studio 2019 and it is able to compile and run the example program here, but there is an issue regarding the theme and icons. According to the installation guide, under the section Building and distributing your application there are some things that must be done to get themes and icons to work.
I've started by downloading the Windows theme the guide suggests and have it in a share directory and then I've created a settings.ini file in an etc directory. It says to place this in the "install directory", which I assume is where Visual Studio is placing the exe for the program. I've tried it in both build and release, in the source files, in the top project directory - all with no success (and I did make sure it is targeting x64).
Just in case I also tried placing these where vcpkg is installed as well as where vcpkg installs gtk. No luck. When the program runs I get the warning
(gtkExample0.exe:16772): Gtk-WARNING **: Could not find the icon 'window-minimize-symbolic-ltr'. The 'hicolor' theme
was not found either, perhaps you need to install it.
You can get a copy from:
http://icon-theme.freedesktop.org/releases
So it seems that it is never finding the ssettings.ini file telling it to use the Windows 10 theme. Has anyone had any luck with getting this to work (both from VS2019 debugging runs and in deployment)?
To summarize the files:
share\themes\Windows10\gtk-3.0\gtk-3.20\ (downloaded from suggested GitHub repo)
etc\settings.ini contains:
[Settings]
gtk-theme-name=Windows10
gtk-font-name=Segoe UI 9
I've placed these in
<VS2019Project>\x64\Release,
<VS2019Project>\x64\Debug,
C:<path_to_vcpkg>\vcpkg\packages\gtk_x64-windows,
C:<path_to_vcpkg>\vcpkg\installed\x64-windows
All with no change when running from VS2019 under Release or Debug.
Theme and icons considered as external resources are not distributed by vcpkg, and the instructions given in the distribution guide from GTK regarding where these resources should be layout on windows 10 are not crystal clear. The problem has also been reported here vcpkg issue#4417.
The solution proposed hereunder is to install
all the resources in the <VS2019Project>\x64\Release directory of your VS project where your .exe application lives [This is a local solution the problem. A global approach should consider the setting of some user-defined free desktop environment variables which is not discussed here]. Icons can be picked from an ancillary MSYS2 distribution and the theme as indicated in the GTK Guide. The solution should be replicated for the Debug branch.
Supposing you have MSYS2, install mingw-w64-x86_64-adwaita-icon-theme package with the pacman package manager if not already done on your MSYS2 installation pacman -Syu mingw-w64-x86_64-adwaita-icon-theme.
Copy C:\msys64\mingw64\share\icons to <VS2019Project>\x64\Release\share\icons
you should get both hicolor and Adwaita icons as subdirectories of your target dir.
Copy the theme resources downloaded in the source gtk-3.20 directory directly into <VS2019Project>\x64\Release\share\themes\Windows10\gtk-3.0\. Do not locate these resources into a gtk-3.20 subfolder: to understand why consult this article Theme Location [assuming here that no global desktop environment variable has been set].
Create a <VS2019Project>\x64\Release\etc\gtk-3.0 directory, put your settings.ini into it.
Recompile and you should obtain a windows 10 look and feel for your application window.
I am developing a desktop application using QT Quick. I have been searching and reading the QT documentation (http://doc.qt.io/qtinstallerframework/ifw-tutorial.html) for creating an installer and how to use windeployqt.exe and binarycreator.exe to deploy on a windows machine. So far so good , but since I want to target this application for windows XP as well.
I want to know exactly what is required to be installed on the target machine to be able to run my application when using MinGW orMSVC2015 during building, so that I may include them in my installer or make the end user download them. Just like we download .Net Framework , Visual C++ Redistributable or DirectX when installing an application.
We use windeployqt to gather all the Qt official dependencis. Two parameters of windeployqt are quite useful:
--debug or --release: determine whether your app is in debug state or release state. windeployqt will put corresponding version of DLLs to your exe's directory;
--qml and put the directory of your QML files after it. windeployqt will search your given directory and put all the QML modules to your exe's directory.
2018-11-05 10:52:34:
It seems the second parameter --qml has been changed to --qmldir.
Is there a cross-platform way to set the application icon with CMake? I am using Cmake 3.0.2 with Qt 5.4.
In the Qt documentation a method is shown but it is not cross-platform.
CMake doesn't handle this for you.
On some platforms are are several "application icons". For example, on a UNIX-like system which follows the FreeDesktop.org standards (essentially anything you can see today on Linux, no matter if it's KDE, Gnome, Unity, XFCE or some other DE-du-jour), this is done by setting an appropriate Icon entry in the application's .desktop file. See the .desktop spec for details. This is what gets shown as a launcher's icon, and some DEs such as the recent Plasma will use this for a window icon in the taskbar, with appropriate theme overrides.
Maybe you are shipping a Windows installer, too, perhaps based on the NSIS. Then you should probably specify this in your .nsi as well.
Actual window icons are something which should be set up by the programmer, too. As you can see, there's plenty of places where an "application icon" might be set. If you're looking for a real-world example, check out Trojitá's source code. Look for actual icon file installation through CMake, for the NSIS code, for creating a Windows RC file, and finally for setting the application icon from the C++ code.
