Mikhail Grushinskiy commented on TOMAHAWK-388:
----------------------------------------------
And one more property would be very useful to check whether at least one of the
nodes is expanded
public boolean isExpandedEmpty() {
boolean expandedEmpty = true;
java.util.HashSet<Integer> expandedNodes = getExpandedNodes();
if (expandedNodes != null) {
expandedEmpty = expandedNodes.isEmpty();
}
return expandedEmpty;
}
public void setExpandedEmpty(boolean expandedEmpty) {
if (expandedEmpty) {
java.util.HashSet<Integer> expandedNodes =
getExpandedNodes();
if (expandedNodes != null) {
expandedNodes.clear();
}
}
}
> Add expandAll/collapseAll or toggleAll details for master detail dataTable

> Key: TOMAHAWK-388
> URL: http://issues.apache.org/jira/browse/TOMAHAWK-388
> Project: MyFaces Tomahawk
> Type: Improvement
> Components: Extended Datatable
> Versions: 1.1.2-SNAPSHOT
> Environment: All
> Reporter: Mikhail Grushinskiy
> Priority: Minor
> Fix For: 1.1.2-SNAPSHOT
>
> Add expandAll/collapseAll or toggleAll details for master detail tomahawk
> dataTable (detailToggler). It seems it can be achieved pretty easily.
> In tomahawk package org.apache.myfaces.component.html.ext HtmlDataTable
> the following methods could be added for that
> public void expandAllDetails()
> {
> int rowCount = getRowCount();
>
> _expandedNodes.clear();
> for (int row = 0; row < rowCount; row++)
> {
> _expandedNodes.add(new Integer(row));
> }
> }
>
> public void collapseAllDetails()
> {
> _expandedNodes.clear();
> }
>
> In tomahawk.tld
> <attribute>
> <name>varDetailToggler</name>
> <required>false</required>
> <rtexprvalue>false</rtexprvalue>
> <description>
> This variable has the boolean property "currentdetailExpanded"
> which is true if the current detail row is expanded and the action methods
> "toggleDetail" which expand/collapse the current detail row;
> "expandAllDetails" - expands all detail rows;
> "collapseAllDetails" - collapses all detail rows
> </description>
> </attribute>
> Also it would be nice to have an attribute to allow initial state to be "all
> expanded", something like allExpandInit="true"
> Thanks a lot,
