JSuggestField - The JTextField that makes suggestions

Submitted by rakudave on 11. October 2009 - 20:03

JSuggestField behaves like "Google Suggest", but you can use it in Java. It extends JTextField, adding special features. You can use it just like any other JComponent.

JSuggestField s = new JSuggestField(this, suggestData);

Archive contains the JSuggestField-class and an example. Tested with jre 1.6

Use one of the following:

public void setPreferredSuggestSize(Dimension size)
public void setMinimumSuggestSize(Dimension size)
public void setMaximumSuggestSize(Dimension size)

Use the setPreferred/Maximum/MinimumSize()-Functions

I can't use it inside a JDialog, since I have no JFrame there to relate it to - that's a pity!
#12Submitted by rakudave on 24. April 2010 - 0:28.

You should be able to replace Frame by Window, and then it should work with a JDialog. It just needs some kind of top-container to attach the drop-down to...

hello, can I set the suggestion box so it will only display maximum 10 items? thx anyway
#15Submitted by rakudave on 27. May 2010 - 0:15.

sure, you can put a simple counter in the run-method of the InterruptableMatcher (located at the bottom of JSuggestField.java) and abort the loop as soon as your counter hits 10...
#16Submitted by Anonymous (not verified) on 13. September 2011 - 0:08.

To display only the top N matches.
this code goes in method run() from the InterruptableMatcher:

... setFont(regular);
int MAX_ITEMS_TO_SHOW = 10;
Vector maxSuggestions = new Vector();
if (suggestions.size() > 0) {
if(suggestions.size() > MAX_ITEMS_TO_SHOW){
//Filter the top N items found
for(int i = 0; i < MAX_ITEMS_TO_SHOW; i++){
maxSuggestions.add(suggestions.get(i));
}
}else{
//Less than the max, add all the items to the new vector.
maxSuggestions.addAll(suggestions);
}
dataList.setListData(maxSuggestions);
dataList.setSelectedIndex(0);
...

Splendid! Thank you.

Besides one question: if field is empty on lost focus event content is replaced with "Type a variable name here...". How to get rid of this?
#27Submitted by rakudave on 5. June 2011 - 0:35.

Yeah sorry this is hard-coded :-/ You'll have to change the source
(I'll try to provide a method for that in the future)

how do i change the size of the popup window of names that appears to 25

#29Submitted by rakudave on 5. June 2011 - 0:49.

Use one of the following:

public void setPreferredSuggestSize(Dimension size)
public void setMinimumSuggestSize(Dimension size)
public void setMaximumSuggestSize(Dimension size)

... but I'm not sure what you mean with "appears to 25"

Hi. I have a question. I saw that you have there 3 methods for redimensioning the JSuggestField, and i tried something like this:

Dimension d= new Dimension(10,10);
s.setMaximumSuggestSize(d);

but it does not work. I even tried on your example and it doesn't work. Any idea why?

Hi,as i am new to java,I don't know how to use this JSuggestField in my Netbeans project.Can anyone suggest me a sample code showing how and where to add this or apply this?
#34Submitted by Anonymous (not verified) on 6. September 2011 - 23:19.

JSuggestField couldnt use on NetBeans normaly like another custom components.

I use it by do some trick
1. drag a JTextField on your form
2. right click on this and choose customize code
3. In initialization code, chose custom creation instead default
4. edit like that
tf_searchStudent = new javax.swing.JTextField()
=> tf_searchStudent = new JSuggestField(new Frame())

5. You look down and see another field for initialization and edit like that , too
private javax.swing.JTextField tf_searchStudent;
=>
/*
private javax.swing.JTextField tf_searchStudent;
*/
private JSuggestField tf_searchStudent;
6. Get some data by use setSuggestData(Vector); method

Hello. I have a problem with this code. I have a program which adds some customers into the database. I have 2 fields of type suggestfield. When I insert the data in the fields everything works perfectly. When I press ok (ok means add data to database and set fields to be not editable), all my fields are emptied(program is supposed ), but the suggestion dialog is opened, without positioning the mouse over the field. And hideSuggest method does not work. Do you know why it does that?
#37Submitted by rakudave on 21. October 2011 - 15:54.

Sounds like a bug. I'll have to do some refactoring anyway, I'll have a look at it. (I'm kinda busy right now, might take awhile...)
