[Gambas-user] R: "Strange" coordinates of mouse with _Drop() event

[Ru Vuott]

Hello Benoît,

well, at this time we are also discussing this issue in the forum of the Italian community of programmers Gambas .

I am attaching a simple application .
I would like to point out that when you start to drag the image to be dredged, also the X and Y coordinates of the mouse pointer - relative to the object (in the example of the application attached it is a "PictureBox" ) that contains the image to drag - are stored.

Then , when the release occurs , and therefore is raised the event of _Drop( ) inside another container (in the example of the attached application it is a "ScrollView" ) , the dragged object is not released to the coordinates in which the mouse pointer is located at the time, but to the coordinates previously stored when dragging begins !!!

So the object is released in the other container (the ScrollView) to the coordinates "where" the mouse was clicked (inside of the PictureBox), when dragging of the image is started.

And more, I known however a slight displacement of the coordinate values ​​at the time of the event of _Drop( ) compared to those stored in the time of initiation of the drag , and for the accuracy : X - 8  and Y + 2.

I hope I have been clear enough.  :-(

Best regards
vuotttt
