Hi everyone, I'm new to the Forum, sorry if I make some mistakes ..
I state that I have been developing software in Visual Basic, C ++, B4A and B4J for years, now I would like to learn Gambas to develop software for Linux.  

Generally I love to draw the interface very well, this pushes me to prefer forms without borders …

I searched one hour online for a solution without a useful result, my problem is the following: how do I move a Form by clicking on a PictureBox and dragging?

I tried to write this script by doing some tests, the Form moves but the problem is that it is moved only when the left mouse button is released .. I would like a smooth and real-time movement to be performed with the movement of the cursor, can someone help me? Thanks

'===== My Try =====

 Hi DavideTr.
Welcome to the forum.

I needed to do this myself for a 'future project' so we both have a solution now.
This is just one way - there are potentially many more.
