Running a QML .exe file on Windows

Kenchan has mentioded the deploy tool arguments.

Windeployqt does'nt know if you are deploying an qml application, so you need to pass --qmldir [your qml root path folder] argument

Note: if your qml root path folder has space characters, you should use double quotes between your path or it will interpret as Different Commands.

@KillerSmath @kenchan I found my posting linkage of stackoverflow is invalid, I update it just now, Here(https://stackoverflow.com/questions/44762836/deploying-qt-c-qml-application-on-windows/55850012#55850012). My problem seems to need some non-dynamic library(DLL), and runtime is unoccupied. Kind of weird. I had already run my program and then I wanna know that's about what.

@Crawl.W
If your apllication is running on test environment, so the windeployqt should able to identify and copy the dependent dlls.
Keep in mind, you also can use --force parameter to copy the dependencies even though they already exist on deploy folder.

@KillerSmath I have tried --qmldir [your qml root path folder], deployed program is still not work.

@Crawl.W
Can you show a detailed command example ?

Crawl.W

@KillerSmath windeployqt --qmldir D:\Qt\Qt5.12.0\5.12.0\msvc2017_64\qml ImWorkStation.exe What I can confirm now is my program need to depend on some unoccupied non-dll at runtime, which exits in qmldir.

@Crawl.W
When i said [your qml root path folder], it means your project folder path where are your qml files.

Example:
D:\MyProject\qml
D:\MyProject

Note: Use --force parameter if you already have old deploy files.

@KillerSmath Good, I changed to where my project's qml file is located, it works. You rocks!
I might have three more questions:

if my project's qml file locate two folder, how I should pass directory?
just because the qml file needs to do this?
Always confused. What are the non-occupied dependencies at runtime but is must when startup? I am targeting two folders: QtQuick\Controls and QtQuick\Extras

1- if my project's qml file locate two folder, how I should pass directory?

If your project is organized as below then pass the project path because the qmlimportscanner will find all files inside the root folder.

Project
- qml_1
  - file_1.qml
- qml_2
  - file_2.qml

2 - just because the qml file needs to do this?
https://doc.qt.io/QtQuickCompiler/#overview

As .qml files are loaded at run-time, it is necessary to deploy them together with the released application.

3 - Always confused. What are the non-occupied dependencies at runtime but is must when startup? I am targeting two folders: QtQuick\Controls and QtQuick\Extras

Depend on which qml files are loaded.

I think this is the final answer to this question.Thanks to @KillerSmath 's for your patience. Thanks also to kenchan.
By the way, last question(with a sly grin),what windeployqt provides is not all necessary, how deploy by the best concise?

hi
@Crawl.W said in Running a QML .exe file on Windows:

all necessary

1 start your app
2 select all the dlls
3 delete them
Only unused dlls will be deleted

Crawl.W

@LeLev Yeah,that's my solution, but it will delete qml file when load at JIT. I wanna know a one-step solution.

jsulm

@Crawl.W "2 select all the dlls" - only select and delete DLLs, not anything else

Crawl.W

Note: I we use VirtualKeyboard will need copy QtQuick\VirtualKeyboard folder to program directory. When use windeployqt to deploy program, qmlimportscanner seems not to accomplish the job. (ENV: qt 5.12 + msvc2017)

Crawl.W

@jsulm This's an uncomfortable operation and that some dll is load at JIT, which need I try all possibilities when deploy.

windeployqt not helping.
Qt_5_12_1_MinGW_64

called windeployqt --quick . in directory with only one exe file
it created bunch of files (64 mb). "dir" output:
