问题 I am trying to export some dynamic content into a PDF file with a small bit of page formatting. I'd like to have the PDF pages have a small padding with a border and then inside that border, a small company logo should appear up the top right on each page. Now the issue is that because the content is dynamic, the number of pages and content per page can vary.

Now, I like to add another link to the "Edit" "Delete" "Details" trio on my custom table view. I'd like it behave much like the "Delete" button, i.e. not call another page, but do something in the background (Here: Send an email.) and then refresh the view. Alas, I fail to understand how this "Delete" link works. It is defined in the

问题 I can currently place static points in the map window: var latlng = new GLatLng(lat, lng); map.addOverlay(new GMarker(latlng, markerOptions)); And I know how to get the bounds of the window.
