Implement a Column Widget
-------------------------
Key: OFBIZ-4080
URL: https://issues.apache.org/jira/browse/OFBIZ-4080
Project: OFBiz
Issue Type: Wish
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.
