I'm using QWebView to run a web app. There are 650+ files. Placing the web app's directory in the source directory does not result in the executable bundling the directory.
How do I include the entire web app directory so that the executable will be able to render the files.
Note: I have currently added index.html as a resource, and can access it with qrc:// - But since I cannot add the entire directory structure to a qrc (can I?), the executable does not include the other files.
You need to put an XML node into the .qrc file for each file you want to use using the Qt resource system.
This can be done using a simple pre-build script. Take a look at qrcgen. Quoting the blog post behind this link:
The script I created, qrcgen, takes a directory and a prefix, recursively scans the directory and generates a .qrc file with the same name as the directory scanned. It has solved my problem, and I hope it can help others. It is also available via PyPI, just "easy_install qrcgen".
In order to update the .qrc file whenever your directory contens change, you need to include this step into your build process:
For C++/Qt projects, you can add this step in the build configuration in QtCreator or add in your qmake file a system(...) statement. Note that such commands aren't portable in general. (If it's not portable, you can put some operating system conditions around multiple commands.)
For PyQt/PySide projects, I don't know how to do this, but I'm sure you find a solution for this too.

I recently finished my first JavaFX project and am ready for deployment. I found that when I create the jar file for my project my ide creates a folder with the jar and other necessary files. I noticed that when I run the jar in the file everything works fine. However, when I take the jar our of that folder and place it as a desktop icon, various resources no longer become available - I am assuming this is because the jar file and the various resource files are no longer in the same file path/folder. - Is this the correct assumption to make?
Regardless, I wanted to ask what is the standard method of getting JavaFX resources and the accompanying jar file to work when the resources are not located in the same folder?
Essentially, I want to have a clickable desktop icon that launches the app, which the jar file fulfills. But if I put that jar file in a folder with its resources to get the project to work properly then the user will have to press the folder and then the jar file in order to get the project to launch - which is very counterintuitive.
Any ideas on how this issue is handled?
The best way to do this is to create a shortcut to your jar file not copy it to another location. The jar file depends on these resources to execute especially if you used external libraries.
The other alternative would be to export your jar file with the libraries included in the jar. This however would make your jar very huge depending on the number of libraries you have.
I hope this helps.
How can I tell doxygen to (only) use the files that are in my Qt project file when generating the documentation?
Reason for asking: I'm using a folder structure where a 'common' folder holds files that are used by some (not all) Qt projects I'm working on. Like this:
projects
MyProject
common_files
SubProject_A
SubProject_B
Both SubProject folders will have a Doxyfile and both projects will use some files from the common_files folder.
I know one way to achieve my goal (getting the documentation for just the files used in my project) is to manually add all files in the INPUT setting from the doxygen configuration file. But that would mean I'll have to change the Doxyfile every time I add or delete a file to/from my project.
Doxygen should be able to filter the files needed for the documentation from the .pro file. But how?
I am trying to populate a QTableview with some data. When developing under Qt Creator, data is read from build directory. Running the program each time, the QTableview keeps getting repopulated with previous data.
If I manually change the build directory each time before run, doesn't happen. But how do I solve the problem without manually changing the build directory every time I want a fresh run?
In your project directory there is a file name ProjectName.pro.user.
This file creating when you configure your project. it's XML file.
you can find this line on *.user files:
<value type="QString" key="ProjectExplorer.BuildConfiguration.BuildDirectory">C:/Users/probook/Documents/Qt/testProject/Build/Windows/Debug</value>
This line define build directory address for debug. there is a same line for Release and Profile in that file.
You can also use Qt creator to define(customize) relative directory build:
goto Qt creator, Tools, Options..., Build & Run, General, Default build directory.
More info:
Qt Creator stores user-specific project settings in a .pro.user file. You can share these settings between several projects as a .pro.shared file. It has the same XML structure as a .pro.user file, but only contains the settings to share.
Based on comment, issue seems to be data which gets saved to build directory. And solution would be to remove it before running the application.
You can add Custom Process Step, either under Projects - Build Settings -
Build Steps, or under Projects - Run Settings - Deployment, and just delete the desired data files. Exact command depends on operating system.
An alternative might be to add a command line switch, something like --development-erase-saved-data, to the application itself, and erase the files (or just not read them, or whatever). Then add that command line switch to Projects - Run Settings - Run Steps - Command Line Arguments for desired build configurations.
Adding support for this in the application itself is easier to maintain, and is almost automatically cross-platform. However, it might be a feature you don't want in the application, though in that case you might only enable it for Debug builds (with #ifdef).
As a side note, saving data to executable directory is not a good idea these days. You might want to save it for example to location returned by
QStandardPaths::writableLocation(QStandardPaths::AppDataLocation)
(See here for more info.)
I want to get a path to the project directory in Qt and reference the other files of my project relative to it. I know this issue have been already discussed here
Get current working directory in a Qt application
and here
How to get current working directory path of a Qt application?
but the answer is still unknown. In case it's impossible to get such a path then what is the approach of navigation among files of the Qt project.
Based on your comment, you are trying to:
Access some images which are being used in my program. I could of course put them into build target directory, but it becomes uncomfortable to pass my code to others.
The approach to store resource files in the project source directory and rely on such structure at runtime is not a greatest idea. I can't imagine the situation when mixing the concepts of initially decoupled source and build directories could be useful, correct me if I'm wrong.
So, according to your needs:
The most simple and plain way is to use the Qt resource system. The resource files are simply embedded into the executable, so there will be no need to access the file system.
Another way is the automatic deployment of the needed files. This answer describes the way to copy your files to the target directory using qmake.
I am working on a plugin for some application, and I am using libtiff. The filter is working just fine, but there is a problem. There are some .dll files that have to be included in compile path. When I add those .dlls in \QtSDK\Desktop\Qt\4.8.1\mingw\bin the plugin is working fine, but when i delete one or more of those .dlls, plugin is not recognised by the application. Those .dll are not included in the Qt SDK by default.
Is there any way I can include those .dll in my plugin and add a path to them without copying them to the Qt SDK bin folder.
Usually I add my plugins to my application directory and add this line of code to main() in main.cpp like so:
qApp->addLibraryPath(QString("."));
Image plugins go in imageformats and SQL drivers (ODBC) go in sqldrivers. You can make the library path anything you want relative to your application root directory. I like to keep things simple and just reference the root directory.
