I have drawn multiple lines on the map to calculate the distance and on the
Double Click i want to erase them and start fresh.
If i use drawcommand.setvalid(false) and after that i repaint the page only
the last line is getting erased and if i use array of com mands for drawing
the lines and then i try to delete the lines on double click using the for
loop, the for loop does not seem to work. i am pasting the code below:
@Override
protected void onMouseDoubleClicked(MapMouseEvent e ) {
System.out.println("inside double clicked" + pointsCount);
for(int i=0; i < pointsCount; i++)
{
System.out.println("inside double clicked" + i);
command[i].setValid(false);
}
getContext().getViewportPane().repaint();
getContext().getSelectedLayer().refresh(null);
}
Can you please give me your suggestions as to how i can solve this.
Thanks
