Adrian Crum commented on OFBIZ-4080:
------------------------------------
Some additional thoughts on this:
1. The column-container element should accept only column sub-elements. If
other widget elements were allowed, then it would be difficult to determine
where they would appear in a multi-column layout.
2. An improved XML example:
{code}
<column-container>
<column name="this-column">
<!-- column contents -->
</column>
<column name="that-column">
<!-- column contents -->
</column>
...
</column-container>
{code}
...because the "first-column" and "second-column" names imply position, and it
is important to keep in mind that column placement could be under the user's
control.
3. I like the idea of including the new elements in form widgets.
> Implement a Column Widget

> Key: OFBIZ-4080
> URL: https://issues.apache.org/jira/browse/OFBIZ-4080
> Project: OFBiz
> Issue Type: Sub-task
> Components: framework
> Reporter: Bruno Busco
> Priority: Minor
>
> Some time ago there was a discussion on the dev mailing list about how to
> implement something to display contents in columns on screens.
> I cut and past an Adrian's idea that is something we should consider to
> implement.
> --------------------------
> From the screen widget XML perspective, it could look like this:
> <column-container>
> <column name="first-column">
> <!-- column contents -->
> </column>
> <column name="second-column">
> <!-- column contents -->
> </column>
> ...
> </column-container>
> The column elements can contain additional column-container elements.
> The column element can have an attribute to specify its width as a percentage
> of the column-container width. Pixel widths should be avoided since the
> screen widgets are supposed to be rendering device agnostic.
> The column-container and column elements will support the common screen
> widget attributes like name, style, id, etc.
> The column-container could support a type attribute that controls how the
> contained columns behave. For example, type="splitter" will render the
> contained columns as a splitter window.
> From the widget model perspective, the column-container manages resizing
> columns when one of them is collapsed or its width changes. Column size
> information needs to be kept in the rendering context. The information would
> start off with some default values that are overridden by user preferences.
