Dear Electric developers,
IMHO measurement procedure in layout window needs to be improved.
At first it would be better if the marker would move interruptedly
in accordance with
Display Grid Preferences minimum size. In this case it would be
easier to hit into the
starting and finishing points of the measurable segment. Now the market moves
continuously and it is difficult to hit into the predeterminated position.
Next the marker for measurements is too sophisticated that causes
uncertainty which end
of it should be used.
I have fixed this in the internal version of Electric. Here is what I did:
(1) I changed the measurement icon so that it looks like a
tape-measure. It is more obvious which is the pointer end. I will
attach a GIF file of the icon, which should replace both:
com.sun.electric.tool.user.ui.resources.ButtonMeasure.gif AND
com.sun.electric.tool.user.ui.resources.CursorMeasure.gif
(2) I added code to
com.sun.electric.tool.user.ui.MeasureListener.java so that it snaps
the cursor during measurement. To do this, I added this method:
-----------------------------------------------------
private void gridMouse(MouseEvent evt)
{
// snap the cursor to the grid
if (evt.getSource() instanceof EditWindow)
{
EditWindow wnd = (EditWindow)evt.getSource();
int mouseX = evt.getX() + gridOffX;
int mouseY = evt.getY() + gridOffY;
Point2D dbMouse = wnd.screenToDatabase(mouseX, mouseY);
Point2D align = new Point2D.Double(dbMouse.getX(), dbMouse.getY());
EditWindow.gridAlign(align);
Point newPos = wnd.databaseToScreen(align);
try {
Robot r = new Robot();
Point offset = wnd.getLocationOnScreen();
r.mouseMove(offset.x+newPos.x, offset.y+newPos.y);
gridOffX = mouseX - newPos.x;
gridOffY = mouseY - newPos.y;
} catch(AWTException e) {}
}
}
-----------------------------------------------------
and I declared field variables "int gridOffX=0, gridOffY=0;"
and I added a call to "gridMouse(evt);" as the first line in the
method "mouseDragged()"
