RGtk2 - retrieve ggraphics mouse coordinates during drag-and-drop event
Hi all,
I have a gtable and a ggraphic widget.
I want to drag an element from the table onto the graphic.
When the drag object is released over the ggraphic widget, I want the
mouse coordinates inside the ggraphic to be returned.
Right now I do not know how to get the mouse ccordinates of the
ggraphic widget at any given time.
How can I access the ggraphics mouse coordinates?
Below you find my sample code (windows only due to ggraphics).
TIA,
Mark
library(gWidgets)
library(RGtk2)

w = gwindow("ggraphics example")

Problems with the borders (High difficulty)
...e dispersed seed are properly included in the SB for the next iteration?
Here I attach you the full model to be this message understandable:
width = 10
height= 10
endt = 6
nPop = 1
SBLL = 1
SBUL = 10
LrD <- matrix(0, width, height)
x <- as.integer(runif(nPop,min=1,max=10)) #uniform random x ccordinates for occupied cells
y <- as.integer(runif(nPop,min=1,max=10)) #uniform random y ccordinates for occupied cells
z <- cbind(x,y)
LrD[z] = runif(nPop,min=SBLL,max=SBUL) #uniform random SB densities assigned to random locations
