/* * Get File Name from a Path with or without extension */ std::string getFileName(std::string filePath, bool withExtension = true) { // Create a Path object from File Path filesys::path pathObj(filePath); // Check if file name is required without extension if(withExtension == false) { // Check if file has stem i.e. filename without extension if(pathObj.has_stem()) { // return the stem (file name without extension) from path object return pathObj.stem().string(); } return ; } else. In the case the string corresponds to a valid file path on the system, a file:// URL is constructed, using QUrl::fromLocalFile(). If that is not the case, an attempt is made to turn the string into a http:// or ftp:// URL. The latter in the case the string starts with 'ftp'

def showDialog(self): fname = QFileDialog.getOpenFileName(self, 'Open file','.pro')[0] os.chdir(os.path.dirname(str(fname))) self.props,self.globdat = InputRead( str(fname) ) print(File ,os.path.basename(str(fname)), is ready. Press RUN to start the simulation.\n\n In the example, we use several methods to print the file path and its parts of the given file name.

Files in the filesystem have a system of protection. Files are given flags which determine who can access and.

The returned value is null if the file path is null. The separator characters used to determine the start of the file name are DirectorySeparatorChar and AltDirectorySeparatorChar. Because \ is a legal file name on Unix, GetFileName running under Unix-based platforms cannot correctly return the file name from a Windows-based path like C:\mydir\myfile.ext, but GetFileName running under Windows. When using relative pathes to access files, these will be relative to the current working directory. So you must set that first using chdir() or QDir::setCurrent: QDir::setCurrent(dir.absolutePath()); Or just use always absolute path names by building them from the base path, an optional sub directory, and the file name. Both methods of invoking the file dialog are demonstrated in the following example. The first button invokes the file dialog by the static method. fname = QFileDialog.getOpenFileName(self, 'Open file', 'c:\\',Image files (*.jpg *.gif)) The selected image file is displayed on a label widget. The second button invokes the file dialog by calling.

The filename always occurs at the end of the string. It can't contain any colons or backslashes, so it cannot be confused with folders, drive letters, or network shares, which all use backslashes and/or colons Now, things become trivial: get the file name and read from the reply: file.write(reply->readAll()); // this is done in saveToDisk() Well, that's it. We will have a downloaded file named download, download.0, etc if we have more input urls If you call GetModuleFileName(NULL,) from within a DLL, you will get the path and filename of the top-level EXE file that ultimately loaded your DLL, *not* the filename of the DLL itself.

Qt5 Tutorial: Resource Files, The Qt resource system is a platform-independent mechanism for storing binary files in the application's executable. This is useful if our application always needs a certain set of files (icons, translation files, etc.) and we don't want to run the risk of losing the files For each filename, the list of paths that were found for that filename are stored in <conflicting_deps_prefix>_<filename>.

  1. The totalBytes is -1 and QT doc says: bytesTotal indicates the total number of bytes expected to be downloaded. If the number of bytes to be downloaded is not known, bytesTotal will be -1. So, it sets the max value for the progress bar -1 which is not right: progressDialog->setMaximum(totalBytes); Used QFileInfo() to get the file size

  3. The path can be traversed element-wise via iterators returned by the begin() and end() functions, which views the path in generic format and iterates over root name, root directory, and the subsequent file name elements (directory separators are skipped except the one that identifies the root directory). If the very last element in the path is a directory separator, the last iterator will.
  4. A QDir is used to manipulate path names, access information regarding paths and files, and manipulate the underlying file system. It can also be used to access Qt's resource system. Qt uses / as a universal directory separator in the same way that / is used as a path separator in URLs. If you always use / as a directory separator, Qt will translate your paths to conform to the underlying.
  5. To compile Qt 5 using Visual Studio easily. Compiling Qt 5 can become annoying, as it's nothing but a routine task that could be time wasting.

For example, when Qt 4.6 was released in December 2009 it included a new QtMultimedia module. Support for that module was not complete until CMake 2.8.2, released in June 2010. That means that if someone wanted to use QtMultimedia, they could either have to wait for and then.

When you run a Qt project, QtCreator first deploys the project to a remote embedded Linux device via ssh and then runs the executable on the remote device. This feature enables nearly instant feedback how your Qt application works on the embedded device. Deployment works fine with the INSTALLS variable of qmake. It does not work out of the box with the install functions of CMake. Fortunately. Then copy the complete qt file tree from Path-To-Qt-SDK\qt to Path-To-Qt-SDK\qt-static (or whatever path you prefer). copy Path-To-Qt-SDK\bin\qtenv.bat to the static folder and adapt content —> replace xxx\qt with XXX\qt_static Cleaning up the folders. As you copied the sources from an existing build, you have to clean it up, before doing a new build. To get this, do the following: delete. Now in Qt Designer menu click View then pick the Preview option, you should get the something like the screenshot above. It looks good right? But watch what happens when we increase our window size: Our objects stay in same positions and have same sizes even though the main form changed size, and even though the button is almost invisible. That's why you should use layouts more often than.

The main interface to the Python Qt binding, realized as a singleton. Use PythonQt::init() to initialize the singleton and PythonQt::self() to access it. While there can be only one PythonQt instance, you can have any number of Python context to do scripting in. One possibility is to use createModuleFromFile(), createModuleFromScript() or createUniqueModule() to get a context that is separated. The convention with Qt 5 is Qt in a compiler-specific folder like P:\QT\MAJOR.MINOR.PATCH\COMPILER_SPEC, or omitting the patch number.

The correct way is to export the QT_SELECT variable and add the custom ~/.config/qtchooser/somename.conf file. This will be a qt installation visible in qtchooser -l under somename. So that: QT_SELECT=somename; qtchooser -print-en generates commands to create .ts (via lupdate) and .qm (via lrelease) - files from directories and/or sources. The ts files are created and/or updated in the source tree (unless given with full paths). The qm files are generated in the build tree. Updating the translations can be done by adding the qm_files to the source list of your library/executable, so they are always updated, or by adding a custom target to control when they get updated/generated Reinstalling the application may fix this problem. Having encountered the problem in the past, I could solve it by appending the plugins by hand like this: import os import sys import PyQt5 dirname = os. path. dirname ( PyQt5. __file__ ) plugin_path = os. path. join ( dirname, 'plugins', 'platforms' ) os. environ [ 'QT_QPA_PLATFORM_PLUGIN_PATH'] =.

The default filename will be determined from QCoreApplication::applicationName() (otherwise qt_temp) and will be placed into the temporary path as returned by QDir::tempPath(). If you specify your own filename, a relative file path will not be placed in the temporary directory by default, but be relative to the current working directory. Specified filenames can contain the following template. Create an RCC file from a list of Qt resource files. Options may be given to rcc, such as those found when executing rcc -help.

  1. Qt 5 Get QListWidget Selected Item . The class variables are used to demonstrate object orientation where several class methods can operate on the class data (only having to read it once per class instance). The size of the variables demonstrate how to handle large text files, with thousands of lines, without having to demonstrate the use of pointers or vectors. The size of the variables are.
  2. The most notable difference is the -qt-host-path option. To cross-build Qt, you need to point to an already existing native build of your host platform. This is called the host Qt. All the native host tools like moc, rcc and uic are run from there. In Qt5, we built the host tools anew for every single cross-build. Re-using the host tools from an existing host Qt installation saves us from building the host tools for every cross-build over and over again and greatly simplifies Qt's build system
