How do I set a selection in a TableView? I want the first index selected by default.
productTable.selectionModelProperty().set(value);
Is this right? What should value be?
The TableViewSelectionModel provides various methods of selections:
productTable.getSelectionModel().selectFirst();
Even the default value should be selected by someone in somewhere. In your case, it is you ;), running above code in some init block.
Generally, TableViewSelectionModel.select(int index) or, if you don't have the index, but you do have the object you want to select handy, TableViewSelectionModel.select(T object). Docs here.

When generate a list of radio (with a dropdownlist), it will select a default value automatically.
But I do not want to select any values as default, how to set this?
Thanks.
The only way to solve this from Studio is to add an empty row to your drop down list. If this is not preferred, then I would follow Jim's suggestion to affect all the drop downs to not contain a default value. To get the wanted affect to this single drop down then JavaScript code would be the proper tool.
Thanks.
It will be radio buttons. Not a drop down list.
As far as I'm aware there's no way to set this in studio.
You can set this in the database as a quick and dirty fix:
UPDATE fields_meta_data SET default_value = '' WHERE id = 'IDOFCUSTOMFIELD';
Nicer, but more involved would be to create a custom version of
modules/DynamicFields/templates/Fields/Forms/enum.tpl
which allows choosing no default value.
One way we've done this by adding a value in studio of "please_select" with a display label of "-please select-" and make this the default.
This way it's obvious when staff are looking at the record that it's not filled in, and we use workflows and reports to catch the exceptions and raise the alert to the appropriate person/s.
I have found a solution to this, although I would like to stress that I would not recommend this as a best practice.
I was using SuiteCRM 7.2.3, and Sugar 6.5.20. So not sure whether this will work in later Sugar Versions.
Create a Radio Drop Down Field
Create your drop down list
Save it
Go back in the dropdown editor and find your dropdown list: In my
example, I had options, 0, 1, and 2.
Create the same options again only as 3, 4, and 5.
Now delete options 0, 1, and 2.
Save the dropdown
MAKE SURE you don't save the field again after you do this, only the dropdown list.
Now go look at the field in the EditView and you'll see that no option is selected. Worked every time I did this. Nothing shows up in the DetailView, so I'm assuming NULL is being passed to the DetailView in this instance, but I'm not 100% sure.
I've got a RadioGroup with 3 cells. I want to hide some controls when the selected index in radio group is 1. That is:
[someControl setHidden: radioGroup.selectedIndex == 1];
I've got a lot of controls will show/hidden when radio group selection changed. Some might show when the selected index equals 0, some might show when equals 2.
I want it to be done by binding, not connect each control reference using outlet.
How to acheive that?
There are at least two ways of doing this, as binding hidden requires a Boolean balue:
Create a property that is of type BOOL and returns YES or NO based on your value comparison, then in your class use KVO to observe the original value and set the Boolean property inside of the KVO observer (this is required to make sure the object is updated at the right time)
Use bindings alone, but create a Value Transformer to transform each value you need into a BOOL as necessary to be interpreted correctly. There is an existing value transformer that changes YES to NO and vice-versa, but for other value transforms you will have to create these yourself, and there is no good way to parametrize them inside of the xib file.
The first solution is probably easier.
I am trying to create a dropdown in AbyyFlexicapture.
The dropdown should be filled from database (i have external DLL ready to do the job) or with fixed values. The problem is I cant find the appropriate element for the job. All i found (the closest) was checkbox group, but I dont know how to use it (add items programaticaly). The documentation on this is very poor ...
Any help would be appreciated!
Figured it out. You just push data to textbox with query and it gets auto-converted to dropdown. But theres no way (at least known to me) how to set up default selection...
Look at the IField.Suggest() method.
After a YUI2 datatable is constructed, is it possible to change configuration settings dynamically?
If draggableColumns was not set true when the datatable was initialized, how can I change that behavior later on?
Similarly, when columns are not identifed as resizable, is there a way to change it later?
I expected a datatable method would allow this to happen (set on/off), but I can't seem to find something like that in the API (http://developer.yahoo.com/yui/docs/module_datatable.html).
So, I tried browsing the datatable object and changing each column's 'draggable' flag. That didn't work and it also didn't seem the right way to do it.
How can I do this?
Every element's configuration object can be accessed via it's cfg attribute.
So, in order to set draggableColumns config property dynamically, you need to use :
myDatatable.cfg.setProperty("draggableColumns", "true", true)
Note that the second boolean argument should be a string. Refer this link for reference.
I've got a table one column of which uses an NSPopUpButtonCell. Try as I might, I can't seem to figure out the way to properly bind everything the way I want it. Here's what I'm trying to do:
I have an NSArrayController plucking items from a managed object context, called 'Field Values'. This is to be used to populate the popup menu for each item (i.e. the list of available choices). I can bind this by selecting the cell in IB and binding its content/objects/values to 'Field Values'.arrangedObjects and 'Field Values'.arrangedObjects.name as appropriate (to get the represented object and the visible title).
I then want to bind the column in such a way that the selected value in each row comes from an array in my controller class, again made visible (and only edited through) another NSArrayController.
So far I've managed to set it up so that every popup menu contains the list of available fields, and that the default value is selected in each of them. Actually selecting an item has no effect, however— it just snaps back to its initial value. I've also managed to find some other variations on this, such as the menu being populated with the selected values, or containing the name of all available values, and the selection containing the -description of the 'none' value I added.
I'm sure I'm missing something fairly simple, but I'm not sure what it is. Presumably there's some subtlety I've missed in how to bind this sort of data (i.e. the Content vs. Content Object vs. Content Value things), but I'm damned if I can see it right now.
Many thanks in advance :o)
I've got a similar set up with a table view, although the data source isn't Core Data based, but I saw one thing you might double check that could be a subtle difference. In my setup for the table column, I have the table column itself bound via content, contentValues, and selectedObject. However, it looks like it's also possible to do the bindings on the actual NSPopUpButtonCell instead. Perhaps it works when the bindings are on the table column, but not when they're on the actual cell? Anyway, there's one thing that might be worth looking into.
Never bind to scroll view, table view or cell.
However, ever bind to table columns.
Watch the title of the Inspector window to be certain of what you're binding.
