keyboard

问题 I think I've tried every combination, but I can't get the alpha keyboard to show the return key. It's always a "Done" button, which is not useful. On a Nexus 7 (4.1), it's worse, and shows a stupid smiley button along with the Done button, which makes no sense for my application. It's fine to have a Done button as long as I have a return button. Here's one of many options I've tried: <AutoCompleteTextView android:id="@+id/annotate_edit" android:layout_width="match_parent" android:layout

问题 Is it possible to detect in my custom Win32 control, while processing WM_CHAR, or WM_KEYDOWN message, whether the keystroke came from the actual keyboard , or was emulated by a call to SendInput or keybd_event type function? 回答1: You could check if the LLKHF_INJECTED flag is set in a low-level hook. I don't think you can tell just by looking at the LPARAM. 来源： https://stackoverflow.com/questions/45008637/how-to-detect-if-keystroke-was-emulated-by-keybd-event-or-sendinput

问题 So I have this code. I'm doing something wrong. I want the left arrow to go back (show the previous image) but it isn't working. It shows the next image (like the right arrow). Whatever arrow I click, left or right it shows the next image. I've tried millions of different things and I can't seem to find the problem. Can anyone help me? I also like the sources to loop. When the last source from the array has been reached, I want to loop back to the first source again (and to the last source

问题 How do I remap a key on the keyboard using Java so that I can give the key a new meaning? 回答1: If I understand the question, it's how to explicitly define behavior for a specific key. Here's how I do this to implement keyboard shortcuts -- hopefully it answers your question. In my example below, I believe you can change 'this' to be the specific component you wish to explicitly set the keyboard behavior on, overriding its default behavior. I usually do this in the context of a panel or frame.

问题 I try to dispatch an keyboard event for the esc key (for testing) this is what i got so far: KeyboardEvent keyEvent = new KeyboardEvent('keypress'); window.onKeyPress.listen((KeyboardEvent event){ KeyEvent keyEvent = new KeyEvent.wrap(event); if(keyEvent.keyCode == KeyCode.ESC){ //do stuff } }); window.dispatchEvent(keyEvent); This works as expected. The onKeyPress listener triggers. But i didn't find out how to set a KeyCode for my KeyBoardEvent? 回答1: Can't use dispatchEvent . Try: import
