In my Qt Project, I want to create some subfolders like Audio or Video.
Something like this:
Project\Media
Project\Media\Audio
Project\Media\Audio\Video
How I can do this?
Is there an way to add a new folder in Qt Creator? Or do I need to create this manually via the explorer?
Currently the only way is to add or create file that is inside of the directory - then the directory will be also created in Projects view of the QtCreator. This is not really that bad, since you can create directory while adding a new class file to the project. When the file is added to the project, also all its parent directories will be reflected in the Projects view.
In qt you use mkdir
bool QDir::mkdir ( const QString & dirName ) const
which will create a subdirectory called (variable dirName)
You could also use cmake which allows you to generate makefiles for every platform you need, itsteand of writing them manually. See code examples here

When working with a Qt project file *.pro one can use for example the $$PWD to reference to the folder containing the project file.
Is there a possible way to define a custom folder path?
Like saying: $$CUSTOMFOLDER = /home/user/folder
I would like to define CUSTOMFOLDER once and then reuse it in the project file so that I dont always have to paste the long folder path. By That the code would also become more readable.
I'm using Qt Creator on Windows and trying to add an image to an icon.
The only way I can get it to work is by specifying the full path:
QPixmap newIcon("C:/Users/slipn/Documents/qt/projetos/exemplo/new.png");
newToolBarAction = toolbar->addAction(QIcon(newIcon), "New File");
I tried adding to the project as shown below:
The image and the code files are in the same directory. I have no clue of what path I should use to make it work. Any hints?
The problem you need to solve, is that your source path and the path where you build or maybe later even install your application are not the same. You need to bundle your image resource with your application, either by copying & installing it to your build/install, or by including it directly in your application binary.
The latter is your easiest bet with qmake. Installing files with qmake is (relatively) easy, but making your build result work without a separate make install step is a different thing.
Your easiest bet to solve both "running your build result directly" and "running the installed application" is to use the Qt Resource System.
Create a .qrc file with File > New File > Files and Classes > Qt > Qt Resource File, add a "prefix" (some name), add your image file there, and then use QPixmap newIcon(":/yourprefix/new.png") to access it in your application.
i have made a MFC-based game and my project includes images and sounds. Now i want to create an installer setup in order to distribute it.
i have used the resources by providing their exact path in e.g
img->Load(L"C:\\Users\\Ad33l's\\Desktop\\block mania\\block mania\\res\\db.png");
MCIWndCreate(NULL, NULL,WS_POPUP|MCIWNDF_NOPLAYBAR|MCIWNDF_NOMENU,L"C:\\Users\\Ad33l's\\Desktop\\block mania\\block mania\\res\\tick.wav");
1.Can someone tell me any way to avoid Hard-coding the actual resource path as these resource files will not be present at this same exact path in other computers ?
2.Also guide me to handle these resource files during the creation of standalone SETUP (i am using advance installer )
(as an actual answer).
Do not use absolute path, always use relative path; relative to your EXE file is one solution.
The EXE path can be found using GetModuleFileName.
char appPath[MAXFILENAMELEN];
GetModuleFileName(NULL, appPath, MAXFILENAMELEN);
(addendum) appPath name is misleading, it contains the full name of the application; you need to extract the path from the full application name.
We do something like this:
(edit to make it compilable in unicode)
TCHAR applicationPath[MAX_PATH];
GetModuleFileName(NULL, applicationPath, MAX_PATH);
CString sSoundFile(applicationPath);
PathRemoveFileSpec(sSoundFile.GetBuffer());
sSoundFile.ReleaseBuffer();
From there, you can do something like (pseudocode-ish):
img.Load( appPath + "//Images//db.png" );
You can have a variable that saves the directory they want to install your program in. After they choose the directory they want to install it in, go off of that. Or you can also use system folders like the appdata folder
A first solution would be to configure your setup project to install the installation files under the DesktopFolder\block mania\block mania\res. Then, you can access within your application the current user Desktop location and append to it the remaining fix location (block mania\block mania\res).
Another solution would be to configure the setup project to create registries at install time which will store the paths of the installation files. Then, your application could read the installation paths from registry.
Finally you could also create at install time environment variables containing the paths of the installation file and, then use within your application the environment variables to access the installed files locations.
I have a question.
How do I create in my project folder with a file. .QSS ?
At the option of creating new files do not have this extension!
I would be very grateful for the help.
Thank you.
Control+N
-> General
-> Chooose
In name write style.qss (you may also choose the directory)
Add to project, or SVN
Drink a coffie or beer
Just create it with a text editor like a notepad and save it with the .qss extension. I suggest to add it in your resource file.
You can load it using the following sample code
QFile file(":/qss/style.qss");
if(file.open(QFile::ReadOnly)) {
QString StyleSheet = QLatin1String(file.readAll());
qApp->setStyleSheet(StyleSheet);
}
Yeah, Qt Creator (I'm assuming that is what you are using) is a little lacking in this area. Just create the folder and file on your file system. Then, in Qt Creator, right click on the project and select Add Existing Files...
I am trying out lua script with C++ in Mac OS X. I was finding a way to make the program returning the current working directory. That's no problem with getcwd, but then I came one thing:
My foo.lua stays at its initial path only. When I compile program, it is not being copied over to the build/Debug directory. Sure, I can grab my script there, but that's just impractical. XCode or any IDE should carry resources to the build zone. XCode does this automatically with iPhone app, but this seems to be a different case. For this case, how to command XCode to put the respective resources in the build directories?
int main (int argc, char * const argv[]) {
...
...
luaL_dofile(luaVM,"/Users/yourNameHere/Desktop/LuaSandbox/LetsTryLua/foo.lua");
//typing the whole absolute path here is just ugly and impractical.
...
...
printf("working directory: %s", buffer);
//output is: working directory: /Users/yourNameHere/Desktop/LuaSandbox/LetsTryLua/build/Debug
...
...
Rather than hard code the path to your Lua script you may want to use the NSBundle API's to find it:
NSBundle * mainNSBundle = [NSBundle mainBundle];
NSString * luaFilePath = [mainNSBundle pathForResource:#"foo"
ofType:#"lua"
inDirectory:NULL
forLocalization:NULL];
luaL_dofile(luaVM,[luaFilePath UTF8String]);
This will find it in the bundle's folder (if you added the "Copy Bundle Resources" build step to your target as the above poster suggested.
Because you're using a .lua file as a resource, I suspect that isn't recognised as a standard resource type and hence it hasn't been automatically copied. You should be able to do this though by adding an extra Copy Bundle Resources build step to your target and then add your file to it in the project view.
If you're creating a command line tool that is not a bundle, then there's never going to be a good solution. If you're creating a regular app then the aforementioned solution will work, but you're going to have to stop assuming that your working directory is set to anything even remotely meaningful at any point in time and use the appropriate methods for finding resources stored within your bundle.
