Hi,

Did you check that the related plugins have been deployed as well ?

V0rtex

@SGaist which plugins need?
There is a file which name is virtualkeyboard on deploy path. And it has five or six plugins in there. Is there any file that i need to copy in my exe path?

SGaist

What if you run your application like this:

QT_IM_MODULE=qtvirtualkeyboard myapp

?

V0rtex

@SGaist should i write in main.cpp or .pro file

SGaist

On your terminal.

V0rtex

@SGaist

C:\Users\hasan.yilmaz\Desktop\TRM RELEASE>QT_IM_MODULE=qtvirtualkeyboard myapp
'QT_IM_MODULE' is not recognized as an internal or external command,
operable program or batch file.

i have this problem.

V0rtex

@V0rtex i write my app name instead of 'myapp' nothing change.

V0rtex

@SGaist ?

SGaist

Right, you are on Windows.QT_IM_MODULE is an environment variable.

set QT_IM_MODULE="qtvirtualkeyboard"
your_app_name

V0rtex

@SGaist

C:\Users\hasan.yilmaz\Desktop\TRM RELEASE>set QT_IM_MODULE="qtvirtualkeyboard" TRM.exe

I did it like that and nothing change.

SGaist

The two separate lines were on purpose.

The next debugging step is to set the QT_DEBUG_PLUGINS environment variable to 1 and start your application. You'll have a log of what of what is happening with the plugins. Check in there the entries related to QtVirtualKeyboard.

V0rtex

@SGaist I can't do it. Can you help me from begining?

jsulm

@V0rtex

set QT_DEBUG_PLUGINS=1
TRM.exe

V0rtex

@jsulm
Sorry but i can't do it . I tried every option. Can you access my pc and help me ?

SGaist

What can't you do ?

We gave you literally what you need to write in Windows command prompt to debug your issue.

V0rtex

@SGaist I figure it out. When i am writing

windeployqt TRM.exe

Automatically it add Qt5Core.dll. It is blocking virtual keyboard. But when i copy Qt5Core.dll from qt path virtual keyboard appear.

After that i copy the all .exe file to another computer which is not installed Qt. Program doesn't work.
0xc00007b ERROR occuring.

SGaist

You should use the windeployqt executable that matches the version where you have the virtual keyboard module installed.

If you have a different QtCore version then it's pretty strange.

By the way, which compiler are you using ?

V0rtex

@SGaist MinGW 7.3.0 32 Bit

SGaist

Did you check that you have the MinGW runtime dlls deployed as well ?
