问题 Is it possible to have a HTML input on a form that only accepts pasted input? As part of our registration process, the enduser needs to enter a 20 character identification token into a basic HTML input form. Ideally, the user would simply copy/paste the token into the appropriate field. We don't want to allow the user to manually type this in, as it is likely that they will mistype letters, and we don't have any reliable means to validate the input. The token comes from desktop software and

问题 I'm using iTextSharp to create a PDF, how can I add a textField into PdfPCell? 回答1: You wouldn't really add a 'text field' to a PdfPCell, you'd create a PdfPCell and add text (or other stuff) to that. mikesdotnetting.com might have the clearest example and there's always the iTextSharp tutorial. 回答2: Give this a try.

问题 I would like to hide the input caret of a TextField in JavaFX8. I already tried to set the text fill to white (my TextField has a white background), but then my user input also disappears. The problem is that the textfield still needs focus, so I also thought of some EventHandler which listens to user input, and focusses on the textfield when a key is pressed, but then I would miss the first key typed. Anyone that knows how to do this? Or is it not possible in JavaFX8? 回答1: Update for Java
