Hello,
my intention is this: when a map is displayed, I press a key - i.e. "m" for
marker or 'Markierung' or 'Mitte' - and then there will be a cross or something
else painter over the exiting map.
If the map is refreshed, I have to press 'm' again, that doesn't matter.
I realized this in the old p.mapper in zoombox.js via
// Bildmitte markieren
function drawMarker() {
parent.mapFrame.jg.setColor('#0000ff');
parent.mapFrame.jg.setStroke(lineWidth);
hbreite = parent.mapFrame.mapW/2;
hhoehe = parent.mapFrame.mapH/2;
xfrom = hbreite;
yfrom = hhoehe-20;
xto = hbreite;
yto = hhoehe+20;
parent.mapFrame.jg.drawLine(xfrom,yfrom,xto,yto);
xfrom = hbreite-20;
yfrom = hhoehe;
xto = hbreite+20;
yto = hhoehe;
parent.mapFrame.jg.drawLine(xfrom,yfrom,xto,yto);
parent.mapFrame.jg.paint();
}
This function was triggered by the kp function:
...
case 109: // m-Taste
drawMarker(); // Mitte einzeichnen
break;
...
I found the corresponding function in the actual pmapper for the keypress, but
how to draw?
Can anyone give me a hint or solution?
Thanks a lot i.a.,
Guido
