[Gambas-user] Label.Resize in Picture1_MouseMove

[Demosthenes Koptsis]

Do you suggest to use the DrawingArea instead PictureBox?

As i see the draw event is in DrawingArea only.

My intension is not to draw something.

i want to resize an object with transparency and border (as Label) and
after to use its X,Y, Width, Height in Image.Copy object.
