Moving window without shortcut

I created my own application and it has its own toolbar. I need to move my app around all the window without shortcut keys, just a mouse click. This would be the same as any toolbar of any KDE application.

How would it be possible?

does it have a title bar?

It does not have a title bar.

The idea is that the application only has one bar that I created and in this bar will be all functions (close, maximize, minimize, moveā€¦).

In case the application has a title bar, my own toolbar will also have the move function.
