Re: wicket-tree checkboxes managing
Hi Sven,
I'm on back on it now.
To hidden the checkboxes for roots I've put the 'if' into the
'newContentComponent' method
something like this
public Component newContentComponent(String id, final AbstractTree<Skill>
tree, IModel<Skill> model)
{
if (model.getObject().isRoot()) {
return new Label(id, model);
} else {
return new CheckedFolder<Skill>(id, tree, model)
{ ... }
What I'd like to do now is to reproduce 'check all/uncheck all' features I
was able to do using a linear/plain list view data structure (the original
structure I'd like to replace with a hierarchical one)
best
massimo

Hi Massimo,
children of collapsed nodes are not present in the Wicket component
hierarchy. I don't understand why you're getting different results
whether you want to select or deselect though.
Instead of twiddling with components, you should perform the mutation
directly on your model objects:
root.selectAll(true):
public void selectAll(boolean select) {
this.selected = select;
for (Foo child : children) {
child.selectAll(select);
}
}
Hope this helps
Sven

Hi,
now that all is looking fine I'm observing a strange behaviuor.
The same method, to 'check/uncheck' all from a button,
public void modifyAllCheckBoxes(final boolean select) {
visitChildren(CheckBox.class, new IVisitor<Component>() {
@Override
public Object component(Component component) {
CheckBox checkBox=(CheckBox)component;
checkBox.setModelObject(select);
return IVisitor.CONTINUE_TRAVERSAL;
}
});
}
seems not working when all are collapsed and if I want unselect all (the
select works).
1. Collapsing all and selecting all works
2. nodes into a branch can be unselected with the button only after having
expanded and collapsed it
page is opened with the tree state = expanded by default
best
Massimo

Hi,
I just rechecked the source of FormComponentPanel and there's nothing in
there which could have any effect on the tree.
Sorry, but I don't have any clue what might be going wrong here.

hello Sven,
the branch just collapsed.
After a tab switching the tree is rightly loaded into its collapsed state
(active arrows + labels) and the same thing does not happen replacing the
'extends FormComponentPanel' with 'extends Panel'. I must add that the
application is very complex and the tree structure is a nested data
structure within a tabbed page (that is actually a Panel).
I'd like make use of a 'FormComponentPanel' because I think it's easier to
perform an update of the model (every tab switching is a save to persist
data).
wicket version is the 1.4.9 and the tree package I'm using is is the 0.4.4
kind regards Sven
Massimo

Hi Massimo,
for the tree it doesn't matter which component it is contained in.
There must be another change causing this.
>why do I get the branches (second level) lost
What is lost, the complete branch or is the branch just collapsed?
Best regards
Sven

Hi Sven,
I'm slowly moving forward and now loading a 2-levels checked selectable tree
within a panel hosted by tabbed page and so on.
The only significant changes I did are related to the model and the data
providing but a question:
why do I get the branches (second level) lost the second time I enter the
tab contaning the tree
when loading the tree itself into a 'formComponentPanel'?
The same thing doesn't happen using a simple 'Panel' instead of a
'formComponentPanel', do you have already experimented something like this?
best
Massimo

Hi,
you can utilize the usual Check/CheckGroup/CheckGroupSelector
combination. I've added a convenience CheckContent implementation
recently (now for Wicket 1.4 too):
http://code.google.com/p/wicket-tree/source/browse/branches/wicket-tree-0.4.x/wicket-tree/src/main/java/wickettree/content/CheckFolder.java
Hope this helps
