Betreff: AW: [Trinidad] Selecting a row in tr:table by clicking on the
row
Hi,
just a little improvement: It is not necessary to set a tableId via
<c:set/>. Your JS Function will also work if you set the parameter as follows:
mySelectRow(this.id, #{status.count});
Regards,
Sven

Betreff: Re: [Trinidad] Selecting a row in tr:table by clicking
on the row
Hi all,
Yesterday I posted a couple of questions on how to change the
tr:table so that a row can be selected by clicking on the row instead of the
radio buttons/checkboxes that are used by default. I figured a couple of things
out myself. I'll try to explain what I've accomplished so far:
* I've been focussing on single selection only for now.
* It's easy to hide the column with radio buttons, since
the TH and TD's in that column get a different CSS style class. I already have
a custom skin.css file, if you want to know how to do that, see the skinning
documentation on the Trinidad website. To hide the column with radio buttons,
just add the following to your skinning css file:
af|tableSelectOne_cell-icon-format-band {
display: none;
visibility: hidden;
width: 0px;
}
af|tableSelectOne_cell-icon-format {
display: none;
visibility: hidden;
width: 0px;
}
af|column_header-icon-format {
display: none;
visibility: hidden;
width: 0px;
}
* To select a row by clicking on it's contents, I add an
onclick eventhandler to the component that renders the contents of each column.
This implicates that the row will not get selected when the user clicks
somewhere in a table cell where no contents are rendered. For example when
using a tr:outputText component, the code becomes:
<tr:outputText value="#{row.someVariable}"
onclick="${mySelectRow('#{tableId}', #{status.count});}"/>
This calls a JavaScript function which is (in my case)
defined in the Facelets page template. (It should be possible to include a .js
file as a resource, but I did not succeed in that approach yet...) Note that
there must be a variable tableId, containing the ID of the table. It can be
defined like this:
<c:set variable="tableId" value="table1"/>
You can use it in your table declaration as well:
<tr:table id="#{tableId}" ... >
* The script that contains the function definition looks
like this:
<script type='text/javascript' language='javascript'>
//<![CDATA[
function kpmSelectRow(tableName, rowIndex) {
var n = rowIndex - 1;
var selBox =
document.getElementById(tableName+':'+n);
selBox.checked = true;
var selectedRow = selBox.parentNode.parentNode;
var table = selectedRow.parentNode;
var rowCount = table.rows.length;
for (var currentRow = 0; currentRow < rowCount;
currentRow++) {
var r = table.rows[currentRow]
if(currentRow == rowIndex) {
if(r.className.indexOf('selectedRow') <
0) {
r.className += ' selectedRow';
} else {
selBox.checked = false;
r.className =
r.className.replace(/selectedRow/g, '');
}
} else {
r.className =
r.className.replace(/selectedRow/g, '');
}
}
}
//]]>
</script>
As you can see, this script sets a CSS class
"selectedRow" on the selected row and removes it again if the row gets
deselected (either by clicking it a second time or by clicking another row.)
* The CSS class "selectedRow" is used in the skinning CSS
file, to change the layout of all cells (TD's) that are contained in a selected
row, like this:
.selectedRow td.af_column_cell-text-band {
background-color: rgb(0, 0, 200);
font-weight: bold;
color: rgb(255, 255, 255);
}
.selectedRow td.af_column_cell-text {
background-color: rgb(0, 0, 200);
font-weight: bold;
color: rgb(255, 255, 255);
}
Notice that we have to do it twice, because even and
odd rows get different CSS classes. This also gives us the possibility to use
different styling for selected rows, matching the "banding" colors. (As you can
see, I chose to keep the selected style the same, regardless of the "banding".)
Following this recipe, I now have a table where a single row
can be selected by clicking on the contents of a cell in the row. Clicking the
row a second time will deselect it. Here's my list of things I want to do to
make it even better. Any suggestions on how to achieve these things will be
highly appreciated...
* It should be possible to select a row by clicking on a
cell (a TD element, so not only it's contents.) I'm still searching for a way
to add an onclick value to a rendered TD element, but this seems hard
(impossible?) to achieve.
* The table component remembers the selected row in
several situations:
* when pagination is used, the selected row is
remembered if the user navigates to another page and back to the page that
contains the selected row.
* when some action is performed on a selected row
(for example a detail page is shown) and the user returns to the table page.
In these situtations, the remembered selection is not
shown using my solution. So I'm looking for a method to re-apply my script
whenever a table is refreshed.
* When using a disabled component to render a
read only value (for instance a disabled checkbox to render a read only boolean
value), the onclick event does not get fired when clicking on the disabled
component.
* I still prefer to place my JavaScript function
in a separate .js file, but I cannot find a method to include such a file any
help on that is appreciated too!
* I don't need it right now, but for the sake of
completeness it would be nice if I could add support for multiple select too.
It shouldn't be too hard...
So far I had a lot of fun figuring this out. I improved
my JavaScript skills a little bit too. I'll keep the list posted of I figure
out more things. If anyone has an idea on improving this solution, please let
met (and the list) know!
Best regards,
Bart Kummel

Re: [Trinidad] Selecting a row in tr:table by clicking on the row
Hi all,
Thanks for your replies. I agree with Shane that
"richness" being a core feature of JSF. However, I find "if XYZ can do it, it
ought to be possible in Trinidad too" a somewhat tricky assumption. With the
right combination of Java, JavaScript, XML, etc, virtually everything is
possible. But I'm asking this question on a Myfaces Trinidad mailing list. The
reason for that is that I'm looking for a solution that requires the least
amount of custom code and will not interfer with standard Trinidad features.
With some additional Googling, I found some useful bits
and pieces. I can now select a row by clicking on it's contents, this can be
achieved by adding an onclick property to the tr:outputText that renders the
contents of a cell in the tr:table. Like this:
onclick="var selBox = document.getElementById
('#{tableId}:${status.count-1}'); selBox.checked='true';
selBox.parentNode.parentNode.className='selectedRow';"
In this snippet tableId is the id I gave to my
tr:table. status is the variable name I assigned to the varStatus property of
the tr:table. As you can see, the JavaScript code also changes the className of
the parent of the parent of the selection checkbox. This is actually the table
row.
Now I have selected a row in the table by clicking on
its contents, I have some additional things to do:
* I have to externalize the JavaScript code in a
.js file. (That's not difficult.)
* I have to add some functionality to unselect a
row. In case of a single selection table, this is done by selecting another
row. This works already for the radiobutton, but the "selectedRow" class is not
yet removed from the table row in that case. In case of a multiple selection
table, this should be done by clicking on the row again. Therefore, the current
selection state should be checked first. I think this is pretty
straightforward, expecially once I have rewritten the solution as a couple of
JavaScript functions in a separate .js file.
* Trinidad does not use the tr element for
styling, but relies on the td elements only. If I change the style of the tr
element, this cannot be seen on the page, because the style is overridden by
the style that is defined for the td elements. If someone has a suggestion how
to solve this, please let me know. (I can think of a solution where I iterate
over all TD's in JavaScript, but this does not sound very elegant.)
* If I succeed in implementing this solution, I
still have the checkboxes/radiobuttons in the first column. Neither the table
cell (TD) nor the box/button itself get a special CSS class from Trinidad, so I
cannot think of a simple way to hide this column using CSS only. Of course I
could set the "rowSelection" property of my tr:table to "none", but that way I
would lose the selection functionality, meaning that I would have to write
something myself. That's not the type of solution I am looking for, as I want
to stay with standard functionality as much as possible. Suggestions are
appreciated!
* Selecting a row by clikcing on its contents is
a step in the right direction, but I'm still looking for a way to make the
whole row "clickable". Does someone have any idea on how I can add an onclick
property to either the tr element or to every td element within a row? Adding
an onclick property to the tr:column results in an onclick property on the
table header. Anyone?
That are a lot of questions in one email... I'd highly
appreciate any suggestions / idea's.
Best regards,
Bart Kummel

Huh?! Richness is the "raison d'être" for JSF; striving
for desktop features is the goal!
I'd love to see something like this too (selection of
any sort on tree would be a step forward). I have to admit that neither my
javascript nor css is up to the task, but what about using goLinks in your
nodes/column cells, use whatever styleClass you are currently using on the
outputText components, then trigger your css changes from the link's js. You
couldn't handle clicking on the whitespace inside the table, but it should be
familiar to users at least (more so than the stinking radio buttons and
checkboxes featured by Trinidad and other frameworks) Besides, if the guys at
icefaces can do it, it ought not to be impossible in Trinidad (naturally,
icefaces doesn't have a treeTable...)

Hi Bart,
I don't know about Trinidad, but for showing selected
row in <t:

field (you can
store in the hidden field the id of the selected object
or the row
index). For showing the selected row you can use css
and for
clicking on the entire row you can use: rowOnClick.

Subject: [Trinidad] Selecting a row in tr:table by
clicking on the row
Hi List,
I'm looking for a method to select a row in a tr:table
or tr:
treeTable by clicking anywhere on the row. I have a
rather complex
UI and I'm looking for ways to reduce the number of
controls the
user sees. One thing I came up with was removing the
radio buttons
in the treeTable on my page. While the user should be
able to select
a single row, I thought it would be nice if the row was
selected
just by clicking anywhere on the row and selection of
the row is
indicated by a different background color and/or use of
a different
font (bold instead of plain).
I found a proposal for this functionality as standard
feature here:
http://myfaces.markmail.org/search/?q=table%20select%20row#query:
<http://myfaces.markmail.org/search/?q=table%20select%20row#query:>
table%20select%20row+page:2+mid:dw257hvw5mgp5g5e+state:results
But this did not make in into the regular builds
aparantly.
Does someone know a way to achieve this without
adapting Trinidad
itself. I think it should be possible with a clever
combination of
skinning (CSS) and JavaScript.
Best regards,
Bart Kummel
