key-events

问题 I have a Form with a rich text box in which i want to do the following: When user presses the spacebar button (Currently i am doing it with keydown event but want to use key press event but it doesn't provide e.keycode), a function should be called in which this logic is to be implemented: last written word is to be fetched and is to be looped through the text of rich text box in order to find its number of occurrences in a rich text box. What i have done so far is: private void textContainer

问题 I want the users to be able to longpress the volumeUp hardware button for skipping a song, and do the regular volumeUp action on a short press. I'm able to differentiate between both (I found this solution, working with flags between onKeyDown, onKeyLongPress and onKeyUp) but I'm wondering if I can still call the standard/super action when the volume up button has been pressed. I can't seem to figure out when the volumeUp action is being called (in the onKeyDown- or onKeyUp-event) and where

问题 Is there any way to simulate keyevent on "OK" or "CANCEL" buttons of Android dialogue box using adb commands? 回答1: One indirect way is:- adb shell uiautomator dump /data/view.xml adb shell cat /data/view.xml calculate OK button coordinates from the relative coordinates given in the xml file. Then do adb shell input tap <x> <y> Hope works. 回答2: Using AndroidViewClient/culebra you can simply do: run java -jar androidviewclient-2.3.25.jar culebra --verbose --verbose-comments --find-views-with

问题 I created this small project to test key events. But when I press keys, it isn't behaving as I want. Actually I need key events for my Calculator project. I created a Calculator project and aside from mouse clicks, I want to add a feature where numbers or operators can be typed from a keyboard. Can anyone check this and help make it more functional? public class FXMLDocumentController implements Initializable{ @FXML private Label label; @FXML private Button backSpace; @FXML private Button

问题 I'm embedding a JFileChooser in my program in my own frame with other custom components in the frame. Here's a design of my app as it may help visualize my issues: If you can't tell, the lists directly under the JFrame titles are JFileChoosers . The way this is supposed to work is you assign shortcuts to destinations and then when you press those shortcut keys, the selected file moves to the destination. My strategy for doing this is to assign the shortcut to a javax.swing.JComponent.WHEN_IN
