how to set the mandatory property dynamically?

Eva Wacker — Thu, 02 Feb 2012 06:13:28 -0500

I need to set the mandatory property of some widgets at the run-time depending on some run time criteria and without having a typed reference to the widget. How can I do this?

I can do this for example for the visible property. I can loop through all components of a display or other panel or container by panel.myContainer.getComponents(), select which components I am interested in and then call setVisible(Boolean) on them.

I cannot call setMandatory(Boolean) on this level but I would need to.

RListDisplay Scrollbar

Emmanuel — Thu, 06 Jan 2011 07:46:58 -0500

I use the RListDisplay Widget in Ivy 4.1.2 and 4.1.3 to display other components dynamically and it works good so far.

The RListDisplay shows a vertical Scrollbar as soon as there is not enough vertical place to show all the components. It is included into a Rich Dialog and the list of components to load in the RListDisplay is built in the Rich Dialog Start method.

The problem is that the scrollbar scrolls automatically to the end of the ListDisplay after the RDC has been loaded. I can not get the scrollbar to stay "quiet" at the 0.0 position.

I have tried with the "ListDisplay.setAutoscrolls(false);" method or with panel.ListDisplay.setVerticalScrollBarPosition(0.0); in the last step of the start method: the scrollbar scrolls always automatically to the end.

I there any solution to this problem?

Richard Schmid — Fri, 23 Apr 2010 11:03:07 -0400

I want to mark the full content of text fields automatically as soon as the text field gains the focus. I use setSelectionStart und setSelectionEnd in the focus gained.

The problem is that I need to create a focus gained event for all text fields. I wonder if there is a more elegant solution to this?

I want to hide table columns if a condition in the value of the cell in the column holds true. For example value.toString().trim() != "*". Unfortunately this does not work, even with a value of "*", the column is not hidden.

RTable is not updated when model is changed

Alain Helfenstein — Mon, 04 Jan 2010 06:08:38 -0500

I use an RTable widget with a ivyScript List as model. I want that the table updates it self when I change an element in my list. E.g. I have a list with articles and I change an article, add a new one or delete one, then I want that the table is updated automatically. How can I do that?

Display NULL values in record set nicely in the RTable

Benedict Groppe — Tue, 28 Apr 2009 09:48:16 -0400

I have a record set from a DB query that I want to use for display in a RTable. Some values can be NULL and the result is that the RTable shows them like java.lang.Object@1234 which is not very useful information for the end user.

How can I make this cell empty for the display?
