1. Run Qt
1. Open the Qt integrated development environment (IDE).
2. In Qt IDE, select "File" > "Open File or Project" and navigate to the directory where your Qt project file (usually a file with a .pro extension) is located.
3. Select your project file and click "Open".
4. Qt IDE will load and open your project.
5. In the left project navigation bar of Qt IDE, expand your project folder, then expand the "Source Files" or "Header Files" folder to find your main source file (usually one with a .cpp extension document).
6. Double-click the main source file to open it.
7. In the top toolbar of Qt IDE, select the target you want to build and run (for example, select an executable or a Qt application).
8. Click the Build button (usually a green play button) to build your project.
9. After the build is successful, click the "Run" button (usually a green triangle button) to run your project.
10. Your Qt application will launch in the Qt IDE's application output window and display your application's interface.
In this way, you can successfully run your Qt project. Make sure that you have correctly configured the Qt project files and that all dependencies are installed and linked before running.
2. Transplant the Qt project
Steps to delete the existing Qt file intermediate files with old configuration and generate new files:
1. Open Qt Creator and open your Qt project.
2. In the left navigation bar of Qt Creator, select the "Project" view.
3. In the "Project" view, expand your project folder and find the "Build Directory".
4. Right-click "Build Directory" and select "Clean Project".
5. In the pop-up dialog box, select "Delete build directory and all generated files", and then click "OK".
6. Wait for Qt Creator to complete the cleanup operation, which will delete old intermediate files and generated files.
7. In the left navigation bar of Qt Creator, select the "Project" view.
8. In the "Project" view, expand your project folder and find the "Build Directory".
9. Right-click "Build Directory" and select "Rebuild Project".
10. Wait for Qt Creator to regenerate new intermediate files and generated files.
By performing the above steps, you can delete old intermediate files and generated files, and generate new files to adapt to different configuration environments. This ensures that the project builds and runs consistently in different environments.
