问题 I am making a java application that includes a JWindow. I want to be able to track the mouse without the user having to click the window after going to another window. 回答1: Your question is little vague on why you want to continue processing the mouse once it's left the JWindow ...but You have two (basic) choices when it comes to mointoring the mouse outside of your application, you can use a JNI/JNA solution or you can poll MouseInfo. The following demonstrates the latter, using MouseInfo

问题 I created transparent JDialog which unfortunately does not work with two screens. When its dragged to other screen it becomes opaque. The code is below, just run it and drag label to other screen. public class TransparentFrame{ public static void main(String[] args) { JDialog dialog = createDialog(); SwingUtilities.invokeLater(() -> dialog.setVisible(true)); } private static JDialog createDialog() { JDialog dialog = new JDialog(); JLabel label = new JLabel("drag me to the other screen");

Make JWindow retain focus when children are focused, including another window as child

由 荒凉一梦 提交于 2019-12-12 04:06:52
问题 I have created JWindow , which has several JTextInput fields. This JWindow parent is JFrame . Now the situation - if text fields are clicked - they get the focus BUT JWindow also stays focused. That is good. But if I create another JWindow (child of first JWindow ), and set it visible, then focus on first JWindow is lost, and the child JWindow is focused. This is bad. Is there some way to retain focus on the parent JWindow , and to make the child JWindow get the focus like JTextInput fields?

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.
