CRACKED IT! I'm sure someone will reply with a two line fix later, but I'm so
damned happy I don't care.
If anyone has the same problem, here is the generic function I used for setting
the default value of the ComboBox to the left value of the dropdown (Like HTML)
rather than the native index of the list items.
// Special function for ComboBox so we can set the default value of the dropdown
// by passing the comboBox object, and the default value
function setComboDefault(combo, leftValue) {
ListItems = combo.getList().getChildren();
for( var key in ListItems ) {
if(ListItems[key].getValue() == leftValue) {
combo.setSelected(ListItems[key]);
}
}
}
Remember this will only work if your ComboBox objects are created using the
same Database table ID's that you are passing to this function.

Subject: Re: [qooxdoo-devel] Setting Combobox Default ListItem
I am still having major trouble with this if anyone can please help.
Here is exactly what I am doing:
I have made my own class of ComboBox that gets values from a database in
pairs of [id]=>[text value];
The [text value] is the visible part in the dropdown, while the [id] is the
value of the selected item. This id is stored in the database when the record
is saved.
This part works fine.
The problem is when I display a record for editing, I want to setSelected the
relevant item in the dropdown, using the id again supplied from the database.
I have this function which I pass the ComboBox object, and the id value of
the list item I am trying to select:
function setComboDefault(combo, leftValue) {
listItem = (combo.getList().getChildren()[leftValue]);
combo.setSelected(listItem);
}
This function only works by the native index of the ComboBox (e.g. 0 to N).
Obviously, ComboBoxEx would solve my problem rather easily, however there is
a bug in this object where it cannot be used on a Window.
So what I need to do can be seen in this algorthym:
function setComboDefault(Object ComboBox, String IdValue) {
ListItems = get all list items of ComboBox
for(each ListItems as ListItem) {
if (ListItem value == IdValue) {
ComboBox.setSelected(ListItem);
}
}
}
Can anyone help with this please?

Thanks mate, that does work, but I had to be able to set it using the
initalVal parameter I passed to the function, with out using a loop.
easily done with if-else with two items but some of them have many items,
and are dynamic.
This is what I came up with and it works:
field.setSelected(field.getList().getChildren()[initialVal]);
Cheers

field.setSelected(item_no);
Just a guess....

Hi Guys,
Spent a good 3 hours trying to do this simple task, and can't find the
way of doing it in the API or Demos.
Take this simple Yes/No Combobox class that I have made:
function ftmDataEntryYesNo (name, xPos, initialVal) {
var field = new qx.ui.form.ComboBox();
field.setCssClassName("ftm-text-fields");
field.setTop(xPos);
field.setWidth(75);
field.tagName = name;
var item_no = new qx.ui.form.ListItem("No");
item_no.setValue(0);
var item_yes = new qx.ui.form.ListItem("Yes");
item_yes.setValue(1);
field.add(item_no, item_yes);
//Set the initial value
field.setSelected(field.getList().item_no);
return field;
}
What is wrong there? I know about field.getList().getLastChild(), the
above code came from a demo example using it. But how do I select a specific
child?
Cheers
Aaron
