Collapse event for Tree GUIBB

Hi experts,
I am implementing a tree GUIBB. I need to react on a collapse event of one single node within the tree. ( The content of the row should change depending whether the code is expanded or collapsed).
The only event that can be fired in thie case is a Lead of selection event without meaningful information, to react on the selected tree node.
Is this a bug in the Tree GUIBB or a limitation?
Dow have any ideas how to solve this issue?
kind regards,
Sahla

Hi experts,
I found the answer to my problem.
The value of the column with column_type if_fpm_guibb_constants=>gc_guibb_tree_columns-expanded. is changed from outside in ct_data!!
ct_data is a parameter of get_data.
Therefore we have the information and we can react.
kind regards,
Sahla

Handling event for Tree Control Collapse

Hi,
Can any one suggest how to handle an event for 'Tree Node Collapse' . I have checked with all the exised tree events.
thanks,
Venu

Hi Venugopal,
    If you are doing tree control programmin then i can suggest you a approach for tree node collapse and expand.
for doing this follow these steps.
1. create a toolbar (use class cl_gui_toolbar), add a button and assign a FCODE to it.
2. here you register the following the event for the toolbar.
gs_event-eventid = cl_gui_toolbar=>m_id_function_selected.
3. here you set the handler for the toolbar events
SET HANDLER gref_application->handle_function_selected
            FOR gref_toolbar.
4. now in your class for gref_application you write a definition and implementation.
definition
handle_function_selected FOR EVENT handle_function_selected OF cl_gui_toolbar IMPORTING fcode.
implementation
CASE fcode.
   when 'collapse'.
      CALL METHOD xref_tree->collapse_all_nodes.
this method might change depending upon the class you use for creating the tree.
i hope this will help you.
in case of clarification do get back to me.

CFDebug says, "widget: Firing selection change event for tree id: t1"

How do I capture this event and code against it. Previously used this code to trap click event:
YAHOO.example.onTreeViewAvailble = function() {
var curTree=ColdFusion.Tree.getTreeObject('t1');
curTree.subscribe("labelClick", function(node) {
TreeItemClick(1,node.data.id)
When the tree becomes available (ie. after the page loads),
this code will run the code above this.
"t1"- tree name in the cftree tag
YAHOO.util.Event.onAvailable("t1", YAHOO.example.onTreeViewAvailble);
I am obviously not an expert with the Yahoo widgets, but I'm learning.
This stopped working for some reason. However the CFDebug consistently shows the subject event happening on every mouse click. I'd rather just use that. Any ideas?

Roy, have you tried to reduce the complexity of your user case?
Try your use case with a simple page without a region in it first and see if you get the eating them. If yes add a region to your page and verify you get the result you expect. Only then add the portal stuff.
This will help to narrow down the error.

Regarding the event for expand/collapse of navigation panel

Hi All,
Is it possible to have an event for the exapnd/collapse for the navigation panel of the portal.
If yes, how to achieve it..
Can we add the event for this or not.
If yes, I want to fire this event from the webdynpro ABAP to collapse or expand the navigation panel of the portal based on some condition.
Is this possible....
Thanks Much.
Regards,
Lekha.

Hi,
See my thread: Hide Detailed Navigation on how to edit the relevant par file.
I guess you can add EPCM event (subscribe) and raise it from your ABAP code.
Hope it helps,

SIZE_CONTROL Event for docking container

Hi, Everybody
I'm trying to handle size_control event for a docking container. But the event is not trigged. See the code excerpt below:

      side = cl_gui_docking_container=>dock_at_left
      extension = 300

I have set the handle_doclist_resize method as a handler for the SIZE_CONTROL event of the CL_GUI_DOCKING_CONTAINER class (by Class Builder).

I have transfered my code just into the one programm. But it still doesn't work I guess the SIZE_CONTROL event is not implemented in CL_GUI_DOCKING_CONTAINER.

Abap WD ALV: Event for calculation row?

Hi,
i have one Abap WebDynpro ALV Component. It is possible to register an event (ON_CLICK) for Cells which are an Link_to_action for example.
My Table:
ID | Group | Var
A1 | Test | 4
A2 | Test | 5
A3 | Dev | 4
A4 | Dev | 6
If i create the ON_CLICK event for the last row, which is then a link_to_action column, i can click on the numbers and the event is triggered
Now i have a table which uses the ALV Calculation feature and the Intermediate Results for the grouping.
My new output view is:
ID | Group | Var
->---Test 9
A1 | Test | 4
A2 | Test | 5
->---Dev 10
A3 | Dev | 4
A4 | Dev | 6
(It calculates the sum of the vars and groups it by the second column)
Now I need an Event if someone clicks on the numbers in the Var Row of the intermediate results row (here: 9 and 10). How can i do this?
If this is not possible, how can i register an event if someone expands or collapses a intermediate result row?
Kind Regards,
Thomas

Line Color in Tree GUIBB

Hello,
May I know if it is possible to change the background or the font of one line in a GUIBB tree.
E.g. After we select a line and want to highlight this line.
Thank you very much.
Shumin

Hi,
As the previous answer was a little oriented on pure WD ABAP rather than FPM, I will try to give the FPM answer: YES and NO
YES -> Yes, you can set the color for the line/cell.
NO   -> No, you cannot set a color for the master column. (Issue addressed to FPM, but if you have any channels please also address it...maybe it gets promoted then )
To set the color for a line or cell you first have to create an additional attribute in the table structure used by the Tree GUIBB. After that you have to redefine the method
IF_FPM_GUIBB_TREE~GET_DEFINITION
in the Tree feeder class
CL_GUIBB_BOL_TREE
and link the cell you want to color to the new cell containing the value of the color:
LOOP AT et_field_description ASSIGNING <ls_field_description>.
    CASE <ls_field_description>-name.
* set color for last column
      WHEN 'AMOUNT_09'.
        <ls_field_description>-cell_design_ref = 'CELL_COLOR'. "name of cell with color value
So now, after telling FPM where to find the color value, you have to define which color to use. Best place - or at least where we did it - is the method
IF_FPM_GUIBB_TREE~GET_DATA
of the Tree feeder class:
LOOP AT ct_data ASSIGNING <ls_data>.
    ASSIGN COMPONENT 'AMOUNT_09'   OF STRUCTURE <ls_data> TO <l_amount>.
    ASSIGN COMPONENT 'CELL_COLOR' OF STRUCTURE <ls_data> TO <l_cell_color>.
    IF <l_amount> < '100-'.
      <l_cell_color> = '06'."set red color for negative value
    ELSE [...]
I hope I could help you!

Deep Linking/URLKit for Tree

Does anyone know if its possible (and if so, how) to use Deep Linking and URLKit to take a user to a particular node in a tree and open that branch item?
Thanks,
Dan

aaaaand? what? nobody knows how to implement urlkit to Tree?
UPD: oh. sorry. i fix it in my head))
UPD2:hmm, fix it not enough
i use this...
protected function tree_changeHandler(event:ListEvent):void
blablabla
stringa =tree.selectedItem.@name;
+
<url:UrlValueRule id="Rule" stringValue="{stringa}" sourceValue="tree.selectedIndex" change="stringa = Rule.stringValue" urlFormat="|*" defaultValue="0"/>
... for my Tree and its change url, but when i enter my new url in browser its reset url and spit in my face...
whyyyyyyyyyyy!
ps:leaving one of stringValue/sourceValue don't make it work.
maybe this forum have some people who implement urlkit for Tree well?

When previewing images by clicking on the thumbnail in an Event for example, I've been finding that many images preview in a 'zoomed in' way so only a small part of the photos is previewed in a highly magnified view.

When previewing images by clicking on the thumbnail in an Event for example, I've been finding that many images preview in a 'zoomed in' way so only a small part of the photos is previewed in a highly magnified view.
Initially I could find no cause. Then I tried right click - Edit and on the affected images, always get this warning:
"Image Cannot Be Edited - This photo was previously edited with another application or with an early version of Iphoto. Duplicate this photo to edit it." and a "Duplicate To Edit" Button is displayed.
The external Editor defined for iPhoto is Adobe Photoshop Elements.
Now, I reckon the MUST be others out there affected by this same apparent Preview bug, yet my searches have not revealed any answers. Also seems impossible to find a contact number for adobe???
Thanks

Client side event for h:outputText... and other JSF component

Hello friends...
I need client side (to use Java script ) event for change in <h:outputText /> or <h:inputText...>.
I want to open a popup window when there is a change in there. I donot want to use onblur() for this. Is there any thing for achiev it.
Thanks.

Hi Jacek,
Unfortunately I think you may be stuck extending Renderer. Another possibility is creating your component via a template, which will be available in JSF 2.0. However, as JSF 2.0 won't be out for a while... you can use JSFTemplating in the meantime:

Good luck!

Need To Return Calendar Events For Current Day

Hello,
I have a calendar which includes seperate start and end date fields. I need to write a query that will return events for each day in a month, but I need to be mindful of the fact that some events span multiple days. Here is my query so far which isn't working quite right.
<cfquery name="qTodayEvents" datasource="#getDatasource()#">
SELECT eventID, title, summary, code, description
FROM events INNER JOIN eventTypes ON events.typeID=eventTypes.typeID
WHERE deleted=0
AND
startDate >= <cfqueryparam cfsqltype="cf_sql_timestamp" value="#todayStartTime#" />
AND startDate <= <cfqueryparam cfsqltype="cf_sql_timestamp" value="#todayEndTime#" />
) OR (
endDate >= <cfqueryparam cfsqltype="cf_sql_timestamp" value="#todayStartTime#" />
AND endDate <= <cfqueryparam cfsqltype="cf_sql_timestamp" value="#todayEndTime#" />
) OR (
startDate <= <cfqueryparam cfsqltype="cf_sql_timestamp" value="#todayStartTime#" />
AND endDate >= <cfqueryparam cfsqltype="cf_sql_timestamp" value="#todayEndTime#" />
</cfquery>
The query is located inside a loop which loops through the days in a given month.
Does anyone know what I am doing wrong? Any assistance would be appreciated.
Many thanks,
Simon

You have to do nested loops - one for the days of the month, and once for the query. It probably does not matter which is nested inside of what. You want your query ordered by EndDate. Then you can do something like this.
ControlDate = Date1;
MaxDate = arraymax(yourquery["enddate"]);
<cfloop condition = ControlDate lt Date2>
<cfloop from = "1" to = yourquery.recordcount index = 1>
<cfif ControlDate >= StartDate and ControlDate <= EndDate>
your code goes here
<cfelse>
break
</cfif>
<cfloop>
add a day to ControlDate
maybe break if the control date is greater than the max date.
</cfloop>

How can organize photos by year? by putting a folder inside of a folder? So putting all of the events for one year under one folder so that it keeps them seperate?

Looking for help in organizing my photos. I would like to organize them so that i can put all of the events for a year into one folder (i would like to keep multiple events under a folder)? Help please?!

Like Larry suggested:
Click to view full size
The top folder could be named 2011. In it could be 12 smart folders each with the following criteria:
Date is in the range" mm/01/yyyy to mm/31/yyyy.
So the 2011 folder would have 12 month smart albums each with the photos for that particular month.
Or you can use the search by date function at the bottom of the window to search by year, month, week or day.

How to set fire action event for particular rows in a table

HI All,
I have a requirement in which I want to set fire action event for particular rows in a table based on some condition.
The table has columns like fullname,employee id etc.
So i want to set fire action event for particulars rows only which will saisfy some condition.

Atanu,
Your approach(setting fire action for few rows) seems not possible. Better to go ahead with workaround.
Do you want this functionality in processRequest(while page loading) or processFromRequest(on some event) method ? Give more explanation regd. your requirement ?
In either case loop through the rows and when your condition is met write the action to be performed in controller.
Regards,
Anand
