Running a QML .exe file on Windows

jsulm

@Crawl.W Did you use windeployqt tool?

Crawl.W

@jsulm Yes,windeployqt can not deploy a executable application，I double click the exe but nothing ever happens.I answer the question on stackoverflow.com where user name is Crawl.W as here.I copy qml floder to runtime directory,and then run the exe, then fell all other unoccupied files heartily.But seemly cannot delete some unoccupied thing in qml\QtQuick, if I delete it double click the exe will have nothing happened.

@Crawl.W
You must pass it the correct arguments not just double click the exe.
did you look at he docs here

Crawl.W

@kenchan My program haven't arguments need to pass. I will read your post linkage carefully and refine some answers here.

@Crawl.W
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.

Crawl.W

@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.

KillerSmath

@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.

Crawl.W

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

KillerSmath

@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.

KillerSmath

@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.

Crawl.W

@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

@Crawl.W
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:

but no changes. application not running.
thought the problem was in my code , tried same on maroon example got same result.
