List item/combo

hi,
anyone know how to programmatically invoke a list item ?
thanx.

Andrew EJ
Thanks, I hadn't thought of that and will bear it in mind. However, my current problem revolves around a non-mandatory item which is currently null. Forms does include a blank value in the list but puts it at the bottom, hence the bottom of the list is being displayed. I don't want to use your technique in this case because it will be updating the item with a value the user has not actually chosen. What I really want is the blank at the top. I will experiment with including a null in my list but I suspect forms might put another in at the bottom.
As for opening the list automatically, I think I will experiment with changing the list style to tlist and increasing the vertical size when the user navigates to it.

List item (combo box) issues...

Hi,
I have a form I'm creating that returns several records based on a query that the user may edit. I do not base these items on database values, but rather control the data within the form. I have created dynamic combo boxes for the return values (ie, they're only visible when valid values are returned to them). Basically, when I click on a combo box after the items have been populated, I want to populate the combo box, but exclude the values in the remaining combo boxes restraining the user from trying to specify the definition for a value type twice. I'm running into two problems. First, I use the when-mouse-click trigger on the combo box to populate the values, however, it seems it's automatically generating a scrollbar within the combo box, showing two arrows (which I don't want but can't seem to disable). Also if a user clicks on it twice, it's continuing to add values. I have used the clear_list function, but that seems to be causing other problems such as removing one value, but leaving another and after 2 clicks stops working. Has anyone done something similar or have an idea as to how I might get the functionality I want?
Thank you.

Can u try to attach a record group to the list item
and you only populate record group with commands
1. Create record group with 2 columns
2. Populate the group
FUNCTION POPULATE_GROUP
(recordgroup_id RecordGroup);
3.Populate list
PROCEDURE POPULATE_LIST
(list_id ITEM,
recgrp_id RecordGroup);
this way you will have better control.Hi,
This actually worked great. Thank you!
The only issue I'm still having is the initial when-mouse-click action is bringing up a scrollbar and minimizing what you can view to one value inside the existing list item, but allowing you to scroll through the list displaying one item at a time (within the list item). If I click twice, the scrollbar disappears, but you still can't see the full list. If I click three times, it starts functioning the way I want it to on the initial click by displaying all values as a combo box list with no scrollbar (all values visible). Is there a behavior I'm overlooking that will force it to behave this way from the initial mouse click?
Thank you again!

List Item Problem(Urgeng!)

Hi all,
I have one list tiem(Combo Box) and I have some element in the list like:
DHAKA
BABNA
DALCHUT
DATABASE
BANGLA
BONDHU
COMMILLA
What I want to do is when my user press B from keyboard the list will show or sort the item starting with B first and and rest of the item. Can I do it? Please reply.
regards,
suddin

no chance. When your focus is in the item you cannot change the elements on key-pressed. This is a feature that forms has only in LOV's. Maybe you should use a LOV instead.

List item problem - couldn't pick a value

Dear professionals,
i used Andreas's code to dynamically populate list item (http://andreas.weiden.orcl.over-blog.de/article-28957008.html) and it works fine (nice work Andreas)!
My problem is that i couldn't pick any value from list - I see many values, but there is now way to choose any of them. (video and picture are here: http://imageshack.us/g/3/property.jpg/)
Also, i spotted that it's not possible to use Combo-box property along with encapsulating procedure - the form is just not opened...
I'm using JRE 1.6, 10gR2 (10.1.2) F&R...
Does anyone know why is that ?
Thanks in advance,
Adnan

You didn't show us the query you use to populate the list. I would guess that all entries have the same value for the VALUE-column of the select, so that they are all "identical" from the value.Andreas bravo ! :))
Yes, you're right - my select statement looks like this:
select a value, "Word" label
from emp;I'll fix it tomorrow - thx once again, generic procedure is excellent !

How to populate List Item from the table in a form builder

I want to know how to populate the List Item (pop up menu and combo box) from a table.
Supposing I have a table Customer(cust_id,cust_name)
and now I want to populate it in such a manner that I can update the data back to the database and also access the list on the form.

This is the method i am using to populate a list.
1- First of all you need to create a non-database list item for customer_name.
2-create this procedure
PROCEDURE populate_list_with_query
--Populates the given list item with the specified query.
(p_list_item in VARCHAR2
,p_query in VARCHAR2)
IS
/* Name the record group after the list item (no
block prefix). */
cst_rg_name constant VARCHAR2(30) :=
GET_ITEM_PROPERTY(p_list_item,item_name);
v_rg_id RECORDGROUP;
BEGIN
v_rg_id := FIND_GROUP(cst_rg_name);
IF ID_NULL(v_rg_id) THEN
v_rg_id := CREATE_GROUP_FROM_QUERY(cst_rg_name,p_query);
END IF;
IF POPULATE_GROUP(v_rg_id) = 0 THEN
POPULATE_LIST(p_list_item,v_rg_id);
/* Force display of first list element label
in the list item. */
COPY(GET_LIST_ELEMENT_VALUE(p_list_item,1),p_list_item);
END IF;
END populate_list_with_query;
3- Create When-Create-Record on the block level and write this code
BEGIN
POPULATE_LIST_WITH_QUERY('bk1.customer_name',
'SELECT customer_name, to_char(customer_id) FROM customer');
END;
In this example, the customer name is the (visible) list label and the customer ID is the (actual) list value
i hope this will solve your problem ...

How to resize the poplist List Item

How can I resize a poplist List Item so that when it's expanded all of my item choices are displayed and the user doesn't have to use a scroll bar to move up and down the list of choices?

The number of choices that are displayed in a poplist (or combo box) is determined by Forms and cannot be specified. However, if you use a t-list you can expand the list by using the height property.

Tooltips don't work with list items?

Hi
I have a list item (I've tried with both combo and poplist), I've set the tooltip and the tooltip doesn't get displayed. I tried setting the tooltip on a normal text item control for comparison and that displays the tooltip. Do tooltips not work on list items?
Marc

It's work in 10gR2.
It's not work with Combo Box!
Could be a problem about what JRE you are working? Jinitiator or Sun JRE.
Try your test on it

Set vertical gap of menu items, list items...

Hi, is there any way to adjust the vertical gaps between menu items, between list items, between combo box list lits? I am trying to make my Java application look like Windows application, but the vertical gaps in these Java components are just too big. Thanks!

Sorry for the massive bit of code, but you can use this to display the UI defaults and decide what to change if you want to try to affect (simple) global changes to the look and feel:
It's far from beautiful but I've found it helpful from time to time.

on text filed B- DELIVERY DATE is assign and at text field D again DELIVERY DATE is assign. I want to avoid this thing and prompt the user regarding the same. How should I go about this? Should I design a button for validation, if yes then what should be the code? or should i go with WHEN-LIST-CHANGE? if so, then what should be the code?
my design time display is like this

lst8
txt9
lst9
txt10
lst10
please suggest something
Thank You
Sam

THe most user-friendly way would be to remove elements from all other lists when they are chosen once. You would have to have a WHEN-LIST-CHANGED-trigger on all listitem and populate the the listitems accordingly.
