The released QT program cannot display icons and images.

Qt compiled in WindowsProgramOn other machines without QT installed, icons and Images cannot be displayed normally.

We can solve this problem in the following ways:

Create the plugins folder in the release folder, and copy the plugins/imageformats folder under the QT installation directory to the release/plugins folder (the imageformats folder contains many INS in image format, such as JPEG ).

The most important step is to add the following statement in Main. cpp:

Qapplication: addlibrarypath ("./plugins ");

Compile the program and then release it.
