Re: [udig-devel] Invalidate a draw command
|
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

Please invalidate a the draw command used to draw the lin in response
to tool feedback.
The draw commands are kept in a queue and always drawn; if you set the
draw command to invald (ie command.setActive( false) ) it will be
removed from the queue.
See http://udig.refractions.net/confluence/display/DEV/3+Draw+Command
I have added your question to the page to help the next person
