The QTQPAPLATFORMPLUGINPATH variable is used by Qt to look up certain drivers including the qwindows.dll. It doesn't know the path to the 'qgis directory apps Qt5 plugins' directory, so you need to provide it before using the QgsApplication module imported from qgis.core. Qt Designer normally ships as a part of Qt Creator. This is Qt's official editor and lets you do a lot more than just graphically design user interfaces. It is a full-fledged and very powerful C IDE.

NOTE: The recommended way to deploy your application is to use the official deployment tool (windeployqt). Try that first! Continue reading this guide only if windeployqt doesn't quite work for you.

The windeployqt tool will gather files from a few different locations. Here is an example of an app that uses Qt Quick to display a picture (PACKAGE-SPECIFIC DLLS ARE NOT SHOWN):

Sometimes, your app might be missing some functionality after deployment. Perhaps a window is blank, an image doesn't show, or a music file won't play. If this happens, windeployqt has probably forgotten to include a file that is only loaded at runtime (like a plug-in DLL).

Here is a systematic (albeit brute-force) way to identify the missing files. This guide is written for Qt 5 and assumes that:

• The release version of your app works correctly when you build + run it from Qt Creator
• Your (dynamically-linked) copy of Qt is installed in C:Qt5.2.1mingw48_32

Initial deployment (Quick and dirty)

1. Close Qt Creator.
2. Copy the following into C:Deployment
   1. The release version of MyApp.exe
   2. All the .dll files from C:Qt5.2.1mingw48_32bin
   3. All the folders from C:Qt5.2.1mingw48_32plugins
   4. (If you used QML) All the folders from C:Qt5.2.1mingw48_32qml
3. Rename C:Qt to C:QtHidden (This turns your PC into a clean environment, just like one that doesn't have Qt installed).
4. Launch C:DeploymentMyApp.exe.

If it didn't work correctly, ask for help (see the Appendix)

Final deployment (Cleaned up)

Do the deletion steps below in C:Deployment and all of its subdirectories. After each deletion, launch C:DeploymentMyApp.exe and test it. If it stops working, restore the files you just deleted.

1. Launch MyApp.exe. While it is running, try to delete all DLLs. The DLLs that aren't used will go to the recycle bin, leaving behind only the DLLs that you need. (This trick doesn't work for .qml and qmldir files, however).
2. (If you used QML) Delete a few .qml files and try relaunching MyApp.exe. Repeat until you try all .qml files.
3. (If you used QML) Delete qmldir files from the folders that have no more DLLs or .qml files

When you have removed all the files that you don't need,

1. Rename C:QtHidden back to C:Qt to restore your installation.
2. Distribute your app.

Appendix 1: How to ask for help

If you still get stuck,

1. Start a new post in the Qt Project forum
2. Say that you followed this guide. Say which attempts passed, and which attempts failed.
3. Describe how it fails, and provide any error messages that you see.
4. Provide a screenshot of the contents in C:Deployment

Remember: The more info you provide, the better your chances of getting a solution!
