Is necessary have QT creator if i already created my interface
-
Hello friends! that is my cuestion. I have created a interface with QT creator and now my intention is create a executable to use this interface. Then, will i need QT creator installed in my laptop after? Thanks!
@AdrianCruz No, you don't need QtCreator, but you need Qt and a compiler to be able to build your app.

If you mean run the compiled app standalone, then please see here

https://forum.qt.io/topic/92577/dll-missing/2@mrjj yes this, then, if i want to run my app (interface) in other computer, because is a app for my final project and i will need to run in others computers. Do i just need to place the missings DLL in the same folder?

@AdrianCruz
Yes , basically its just a folder with the Qt dlls you app needs.
There is tool to help get them. -

@AdrianCruz You should take a look at https://doc.qt.io/Qt-5/windows-deployment.html

Warning: Cannot find GCC installation directory. g++.exe must be in the path.
And also, after, many DLLs are still missing. What is the issue?

@AdrianCruz I found the problem. Just needed to include the installation of MinGW in the path. Now the windows tool run properly but, i have found a new issue, when i try to run the .exe, i receive of windows a message that it says that it cannot find libwinpthread-1.dll. Another solution?

@AdrianCruz said in Is necessary have QT creator if i already created my interface:

No, please don't add MinGW to your PATH! This can break other apps.
You should deploy your .exe and DLLs properly. @JonB already mentioned the Windows deployment tool: https://doc.qt.io/Qt-5/windows-deployment.html
At the end of the deployment, the required MinGW and Qt DLLs will be in the same folder as your .exe.

@JKSH then, i will delete the MinGW of the path. But when i am using the windows tool and the tool returns this :

Hi,
What path are you using to load it ?
What about using Qt resources system to get it builtin in your application ? -
Now it's fixed, but i have another question...ajajaja
I have my app working without opening QT creator, but the background picture of my app is not appear, why??
@AdrianCruz said in Is necessary have QT creator if i already created my interface:
the background picture of my app is not appear, why??
Some possible reasons:
- Your app can't find the picture
- You didn't deploy the required image plugin
How do you load the background picture?
-
@JKSH with the next code:
QPixmap bkgnd("../InterfazKinect/img/foto_index_sinTXT.png");Running in QT creator the picture appears but using the executable not.
@AdrianCruz
well its a relative path.
so if u go to exe. and go one step back it expects there to be
InterfazKinect folder and inside there the img folder.
To avoid this, you can use q resource files.
http://doc.qt.io/qt-5/resources.html
http://www.bogotobogo.com/Qt/Qt5_Resource_Files.phpits then compiled into exe.
