jframe

问题 I need to take all the textField, comboBox, jlst, and jslider input from the first frame and make it into a summary in the second frame after the Submit button is picked. I can't figure out the best way to do this. My assignment requires a popup second frame with a textArea and exit button that brings you back to the first frame. import javax.swing.*; import java.awt.*; import java.awt.event.*; import java.util.Hashtable; public class Ch10Asg extends JFrame { private String[] flightNames = {

问题 I am making a Java gui project and it consists of two frames. The problem is that when I call the secondframe from the firstframe, I have set it such that the firstframe visibility is set to false.

GridBagConstraints gbc = new GridBagConstraints(); gbc.weightx = 1; gbc.weighty = 1;

问题 I am creating a game in java using Swing. I am using mainJFrame.setExtendedState(mainJFrame.getExtendedState() | JFrame.MAXIMIZED_BOTH); on my JFrame to start it as a maximized window. After this I am using mainJFrame.pack(); to be able to get the correct x & y coordinates of components in the GUI. I need those coordinates since i'm painting custom images to the GUI.

问题 Question may be different than what you expected, but I'm creating a utility function for JFrames to make it easier for future me. public void setJframe(String title, int w,int h, JFrame name, Boolean maximize){ name.setSize(w, h); name.setTitle(title); if (maximize == true) { name.setExtendedState(name.getExtendedState()|JFrame.MAXIMIZED_BOTH); } else { name.setLocationRelativeTo(null); } } I want the ability to name the JFrame as I type in the parameters.
