I've found a link that I was searching for to have the "QtTreePropertyBrowser" widget on my Qt Creator. Nevertheless, I don't know how to build it. What is the work flow? I'm using Qt Creator that is already built taken from Synaptic Manager, Ubuntu (pre-built). Should I compile from source first the Qt Creator in order to build the package of QtTreePropertyBrowser that I've just found?
Thanks in advance.
I've never tried to build and integrate a component into Qt-Designer so the following is just a guess, but I hope I show you the right direction: you do not need to compile Qt-Creator, what you need is to compile the component which is a plugin for Qt Designer. I can recommend two documents:
There is an INSTALL.TXT in the source code you found which tries to answer some of the questions you asked. These are the headlines:
INSTALLATION INSTRUCTIONS
Unpacking and installation
1. Unpacking the archive (if you have not done so already).
2. Configuring the package.
3. Building the component and examples (when required).
4. Building the Qt Designer plugin (optional).
Using a component in your project
In Qt's doc there is a page called Creating Custom Widgets for Qt Designer.

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 have build an app using C++ and Qt on QtCreator. The result is a .app file.
Now, when I am running it from the Qt Creator it is running fine.
But when I am running it on a different machine (with no Qt installed) it is not running.
I have figured out the reason is because my .app file is not deployed properly (as there is no framework folder added in the .app)
But I am now having trouble solving it. I am following this link but not getting anywhere as it for console purely.
Is there a way I can fix it using Qt Creator?
A Qt application relies upon Qt's libraries, which must be shipped with the application, inside the built application bundle. The steps for deploying a Qt application for OS X are detailed in the documentation.
If you're not using any other libraries, besides those of Qt, you just need to run the tool macdeployqt, which is part of the Qt installation, in the bin directory. You can set this up to run as a build step in Qt Creator, but I suggest only doing it before you actually deploy the final bundle to another machine.
Calling macdeployqt will copy the necessary Qt frameworks into the bundle and setup the paths to the frameworks so that the binary in the bundle knows where to find them.
If you use any other frameworks or libraries, you need to copy those yourself and set the references to them using install_name_tool
I have Qt application on Lnux. I want to create a executable/set up for this so as to distribute it on Windows and there is no need to install Qt. I have created the executable for this by including all the dlls
but to run it user needs to go inside the folder.
I want such user do not need to go inside any folder,he can directly click the icon can run it. Or such tha user downloads the set up, and install it.
What can be done for this?
You can use the Qt Installer Framework which could be downloaded here. The Qt Installer Framework provides a set of tools to create installers for Linux, Microsoft Windows, and Mac OS X.
You can compile the Installer Framework on your own, but i think using a prebuilt one is more convenient. You can see the Qt Installer Framework Manual for a complete guide on how to make off-line and on-line installers. Creating installers is described here.
A tutorial for creating simple installers for small projects is available here.
I had a working C++/Qt application. I updated MinGW, Qt and Qt Creator to the latest versions, and now I get an error at compile time. This error does not seem to be due to my code, but to the build system.
E.g.:
17:11:15: Running steps for project MyTest...
17:11:15: Starting: "C:\Qt\qtcreator-2.6.0\bin\jom.exe" clean
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
17:11:20: The process "C:\Qt\qtcreator-2.6.0\bin\jom.exe" exited with code 3.
In the project settings there is the message "qmake: No Qt version set. Cannot run qmake."
My source code is just what you get automatically when you create a new application.
I updated the system environment path with the new Qt and QtCreator directories.
I do not know what else to do...
Thank you!

Please go to Tools->Options->Build & Run->Kits and check that there is a Qt version set up in the kit you are using.
If not, then check the Qt versions creator detected in Tools->Options->Build & Run->Qt versions. Is the version you want to use there? If not: Add it here.
Then return to the kits page and set one of the kits to use that version. Double check the other information while there.
Now you should be able to build your project. You might need to close/reopen it though.
Initial setup seems to be a bit bumpy... but it works really well once you get over that initial hurdle:-( There are quite some improvements in the next update for this. Check the Qt 5 RC2 packages, the creator included there already contain most of the fixes if you are curious).
My IDE of choice for the Mac (at least for C++ and Objective-C development) is Xcode. I have a 64-bit Intel Mac with OS X Lion installed, and Xcode version 4.2 downloaded from the Mac App Store.
My problem is that Qt is apparently not compatible with Xcode 4 (it crashes when launching projects generated by qmake), so I'm basically asking how I can integrate Qt with Xcode. I don't have to be able to run and debug the project from Xcode, just build it.
So I thought it might be a solution to use qmake as an external build system within Xcode, the problem is that I have no idea how to set up qmake as my build system, so that I can develop my Qt applications in Xcode 4.
Please help me! :)
Google shows up many pages, but this Qt4 with Xcode page appeared at first glance to be a fairly definitive resource. However, it was last changed in 2006.
Please check out: http://qt-project.org/doc/qt-5/macosx.html
There is a much more recent Qt Developer Network forum post that seems to have good info in it. Specifically, this reply from August 19, 2011 gives a complete recipe.
Update 25/05/2016:
The first two links are now dead, and not archived due to robots.txt.
However, I've updated the link to the forum post.
And here's a copy of emiguel's answer. It is now 5 years old, so I don't know how current it still is.
Hi,
To solve my problem I did the following.
First I`m going to have a subproject in Qt that mantains the graphical interface, I created this project as a C++ library, so I could include this in the main project.
The main project is a C++ project in Xcode (which is a plugin template with a lot of configurations).
Second, I ported the Qt project to Xcode using the spec macx-xcode parameter.
Third, having both projects in Xcode, I can attatch the library (in Qt) to the main project. To do this, right click in the xcode project and click in the "existing file..." option, select the xcodeproj file from the Qt project. Finally add the library to the linkage phase, this is done by dragging the lib file, wich is under the xcodeproj file, to the "Targets" section in the "Link binary with Libraries".
Fourth, import the Qt framewoks to the main project, to do that, right click in the main project, click in add a existing framework, select the Qt features used by the project (ex. QtSDK/lib/QtCore.framework)
And finally, add the header and library paths in the main project. Click in project menu->project settings, set the header search paths option with the Qt headers (ex QtSDK/include//) and the library search paths (ex QtSDK/lib//**).
That's all, now I can instantiate my own Qt widgets from the C++ project.
Note: I have to do an additional step because my target was i386 and the downloaded Qt version were 64 bit, so I downloaded the sources and compiled it for i386.
Now I have another problems about drawing inner the plugin... but I think that will be for another post.
Thanks a lot for your help
Finally, current information on building Qt in Xcode is available in Qt for OS X - which is too long to copy here, and will be maintained and updated by Qt...
