Skip to main content

Java Jframe centers my buttons ):<



Here is my code:







public class Main {

public static void main(String[] args){

JFrame frame = new JFrame("Vex Development Studio 2.0");

frame.pack();

frame.setVisible(true);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setLocation(10,10);

//make variables

File newproject;



Container content = frame.getContentPane();

GridBagConstraints gbc = new GridBagConstraints ();

Dimension buttonsize = new Dimension(75,25);

Button about;

about = new Button("About");

about.setPreferredSize(buttonsize);

//add content

content.setLayout(new GridBagLayout());

content.setBackground(Color.white);

gbc.gridx = 0;

gbc.gridy = 0;

content.add(about,gbc);

//main stuff

//about button

about.addActionListener(new ActionListener(){

public void actionPerformed(ActionEvent ae){

JOptionPane.showMessageDialog(null, "Example", "About", 1);

}

});

//some extra crap

frame.setSize(700, 500);

frame.show();

//end

}

}







I have all the code right, and I have all the required imports, the problem is: I need the buttons to be at the top left corner of the window. Thanks in advance! (:

  1. Because in your gridbaglayout, there's only one square.

    And I suggest to use a JButton instead of Button.

    mixing AWT and Swing is a bad idea.

  2. To anchor the button to top left of the content pane, you can use

    gbc.anchor = GridBagConstraints.NORTHWEST;


    or equivalently in new notation, I believe you can use

    gbc.anchor = GridBagConstraints.FIRST_LINE_START;

  3. If you want total freedom over you layout, do setLayout(null);

Why is this Javascript much *slower* than its jQuery equivalent?

I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
