How to create a .dll file which does some GUI tricks ?

In that GUI , I have an image which changes its colour by MouseButton Clicked event. I want to create such dll.

@hjohn
for creating a shared library see this.
In the QWidget then overrride mousePressEvent() handler to react to mouse clicks and do some stuff.

Yes it is possible. A dll with GUI is no different than one without, just follow @raven-worx's link and read the docs on how to create a shared library.

I am using centOS .
I have added my .so file into particular debug folder of project in which i want to use.

:-1: error: error: /home/local/build-TestDll-Desktop_Qt_5_5_1_GCC_64bit-Debug/libMyLib.so: No such file or directory

i have already added .so file in that path.If i run this project in windows (after changing files path).It works properly.

@hjohn Your original question was how to create a shared library. Now you say you added it already. So, what do you actually want to do? And why do you manually put your library to the build directory?!

hjohn

@jsulm
Yes , I created a library after asking the original question, just for learning purpose.
Now I'm running it on windows , and it works but when I try to do the same in Linux, its displaying that error message.

@hjohn Does it exist: /home/local/build-TestDll-Desktop_Qt_5_5_1_GCC_64bit-Debug/libMyLib.so ?

hjohn

@jsulm yes It does.

@hjohn Can you show your pro file?
