I'd like to display informations about a book in a CellTable in GWT. For example its content.
How can i create a TextColumn that displays that much text. Multiple lines or a scrollbar is what i'm looking for.
Thanks in advance
If your content is plain text, you can put it in TextColumn. It will wrap within a cell, unless some CSS prevents wrapping.
If you want to set a limit on how high a cell can be, add a CSS rule to this table:
.myTable tr {
max-height: 100px;
}
If you have formatted text, you will need to create your own Cell by extending AbstractCell:

Hello im making a program and using TableModel. I have 6 column filed with string's. I want the sixth column string make it look like URL. When i mean look like URL , i mean turn it into blue and be underlined. Is it possible to do that?
You need to write custom TableCellRenderer for your jtable. See this link.This may be helpful for you.
Sun had a very good tutorial (http://docs.oracle.com/javase/tutorial/uiswing/components/table.html#modelchange) on cerating jtable. just go through it before you start. hope this tutorial will help you.
But below is my suggestion.
("<html><b><u>link</u></html>");
<html><b>bold</b></html>
a similar kind of thing
However, I wouldn't recommend altering the data in your model just to effect display. Instead I would create a custom cell renderer which accomplishes this effect and set it on the table. You could either wrap your text in the HTML or manually set font color and style properties on the renderer to mimic html.
Now even if you were to include the url in the html you still can't click on it. There is no component in the table. You don't really want to go into edit mode when clicking on a url. You just want to open that link. To accomplish this you would add a mouse listener to the table itself. When you receive a click event, you would then programatically determine which cell it was over, go back to your model and get the url, and finally use other Java API calls to open that url.
I'm pretty sure you can simply create a string containing
<html>...</html>
and it will work. Just code your link inside the html tags as you would in html. You'll just have to add extra code if you want it to appear blue. I think:
<font color='blue'>
would do it
Sorry for the simple question, how to change the font in the grid?
If you are talking about the text which might be displayed in one of your columns, you can do this easily with cells. When you set up your ColumnModel class, you can pass a custom cell to one of the columns. Then, with html and css, you can style up the column per your needs.
If you want to change the column headers, then you can simply pass some SafeHtml to that column's ColumnConfig.setHeader(SafeHtml) method. Again, this would be done when you set up your ColumnModel. This let's you style up the header however you wish.
If you do use images or css, I highly suggest using the ClientBundle and CSSResource classes.
I have a JList with items that I want to show two values. Is there a way to have it show a string name and then have a right justified string to show a value. Looking something like this:
Title__________________120
Title2_________________135
Is it possible to pass in two string to an item and have the first string display on the left and the second one on the right?
Sure, implement a custom renderer. You might return a JPanel with BorderLayout as the rendering component, with the LHS text in the WEST, and the RHS text in the EAST.
Another way is to shove HTML into the default renderer (a JLabel), using an HTML table that stretches across 100% of the width. Though the custom renderer would be a better choice for a number of reasons (e.g. not presuming the type of the default renderer is a label).
BTW - perhaps you should consider using a JTable for this kind of functionality. No hacks or custom classes needed.
..does the jtable allow selecting items?
Of course! Here is an example taken directly from How to Use Tables in the tutorial. 'Jane' is selected.
A table is a little more effort to set up and get right, but it is well worth the effort.
Would a JTable perform just as a JList ..
No, the table ultimately provides more functionality. But the things it does which a list can also do, work (for the user) in much the same way.
Is it possible to get multiline (say 2-line) row in JFace tableViewer? I want my long text part spreaded between two lines, and my short lines aligner vertically in the cell. How can I achive that result?
The table control itself does not support this. You will have to paint the content of those cells yourself. There's an official example (Snippet006TableMultiLineCells) on how to do that.
I'm trying and failing to understand how to use Java's text editor components to colorize text as you insert it. I don't want or need a fully featured syntax highlighting library.
Basically, I have a JTextField (or some other JText... component), and a list of words. I want any words in the field that appear in the list to be red, and the rest of the words be green. So for example, if "fire" is in the list, "fir" would appear green and "fire" would appear red.
I've tried using a JTextPane and a DefaultStyledDocument, using a KeyListener to go over the text in the document and using AbstractStyledDocument.replace to replace the existing words with versions that have the correct attributes. This didn't do anything. What am I doing wrong?
Neither JTextPane nor JTextField isn't able to present formatted text, i.e text having more than one format. For text-editor-like capabilities like you'd find in WordPad or HTML, the component to use is the JEditorPane or its descendant, JTextPane.
The simplest thing you can do is set the ContentType of the JEditorPane to "text/html" and simply set its text to a string containing HTML. The Java structured text components are surprisingly competent with HTML; you can display tables and/or DIVs, and there is support for much of CSS2. Simplest to do your styles inline, but you can even do external style hrefs.
If you want to get fancy programmatically, you can access the DocumentModel and create text from spans of text each having their own formatting. The DocumentModel works essentially like a programmable text editor.
EDIT: Re-reading your question, I see my answer doesn't quite address it. Since you want multi-colored text JEditorPane is your only option; but rather than just piping in pre-colored text via HTML or such, you'll have to put a listener on your document model to catch changes introduced when you type; and after every document change you'll want to examine the text (again from the Document model) for text that should or should not be highlighted, and you'll want to apply formatting to certain runs of text.
There are devils in the details, but this should get you started.
