how to insert a node to existing check box tree

[jamindhar]

Hi,

i have a checkbox tree with some nodes. based on some selection i need to insert the node in between the nodes of the checkbox tree. please let me know how to implement this


thanks

[JIDE Support]

It depends on which TreeModel you are using. If your TreeModel subclasses AbstractTreeModel, please try AbstractTreeModel#insert() or insertInto().

Thanks,

[jamindhar]

Thanks for your quick reply. sorry i couldnt give you the actual requirement. the following are the requirements for my UI.

1. The ui should display one check box tree with search facility and able to add the nodes in between them. for that we wrote a small piece of code .but we are facing two problems with this code.

1. we could not add the nodes in between the other nodes.
2. when you are selecting a search node .. all the nodes are being selected.


please find the below UI screens and code ..

Please help me out..

Please try use DefaultMutableTreeNode#insert() to insert a new node between existing nodes.

I'm sorry that I'm not quite understanding the second question you mentioned. From the image you post, I think it is a normal behavior, that all child nodes are selected when you try to select the parent node.

Thanks,

[RajaRajeswari_V]

Hi,

The second question is

1.we implemented search facility for the sample dialog. if you see the second screen shot in the previous mail ,we can search the node by giving some input in search field and accordingly it is displaying the node information. but when we select the displayed node then all the siblinbs are being selected.that is shown in the first ui screen shot in the previous mail.

please help me out...

[JIDE Support]

Do you mean the "Child1" is selected when you select "subChild1"? It is the default behavior for the CheckBoxTree. You could override CheckBoxTree#createHandler() to define your expected mouse clicking behavior.

Thanks,

[RajaRajeswari_V]

No. if i clicked on subchild1 then all the subchilds i.e subchild2 ,subchild3,subchild4 are getting selected.

For example ..consider the following tree

Child1
subchild1
subchild2
subchild3


if the user is searching for subchild1 ,he will give the same text in the search field . then following view will be displayed in the ui..

Child1
subchild1..

then the user selects the subchild1 then all the subchild2 ,subchild3 are getting selected.

to show this i attached the ui screens also.please help me out..

[RajaRajeswari_V]

for more clarity if you see ui.jpg which was sent on earlier thread

case 1:

i am searching with child1 text in search field..

then it is showing the following information

child1

subchild1


then i selected the subchild1 ..then the child1 is also get selected which is normal tree behavior

case 2: please see the ui1.jpg

after that i changed the text to child... then the problem is coming ..previously i selected only subchild1 ...but it is showing all the subchild1 & subchild2 & subchild3 as selected..


i hope the problem is clear to you.. please help me out..

[JIDE Support]

Got you. For dependency reason, we will probably have to add a new CheckBoxTreeSelectionModel class for Filterable scenario. Will see if we can find a good solution soon.

For now, Please try the following code. I have tested that it could solve your issue although it is not perfect yet. Please let us know if you encounter any issue.

Code: Select all

Thanks,

[jamindhar]

it solved my problem. but again it is giving one more problem.

i can select all the selects all the childs by clicking their parent node. but to remove if i click on the parent node it is not changing it state.. i.e consider the follwoing tree

child1

subchild1
subchild2
subchild3

if click on child1 then all the subchilds are selecting.but if i am trying to unselect child1 it is not working ...please help me out

[JIDE Support]

Please try change the line in method isPathSelected() from

Code: Select all

                            if (parent == path && _tree.getModel() instanceof FilterableTreeModel && ((DefaultMutableTreeNode) parent.getLastPathComponent()).getChildCount() > 0) {


to

Code: Select all

                            if (parent == path && _tree.getModel() instanceof FilterableTreeModel && ((DefaultMutableTreeNode) parent.getLastPathComponent()).getChildCount() > 0 && ((FilterableTreeModel) _tree.getModel()).getFilters().length > 0) {


Although it's still not perfect enough, it is what we can do best right now. We will consider add a new selectionModel class to address this issue.

Thanks,

[JIDE Support]

Just so you know, this bug is fixed in 2.6.7 which was just released.

Thanks,

[jamindhar]

Thank q for considering my request. today i downloaded the jide version and evaluted. it solved my problem but one problem is coming with this code. it is allowing me to select n-1 nodes only.not n node.

For example

Root
child1
child2
child3
are there .i am able to any of two childs . if i am trying to select all the child nodes then it is giving the following exception

Will fix it in next release. Please try the following code for now to work around.

Code: Select all

        _tree = new CheckBoxTree(filterData.getDisplayTreeModel()) {
            @Override
            protected CheckBoxTreeSelectionModel createCheckBoxTreeSelectionModel(TreeModel model) {
                return new FilterableCheckBoxTreeSelectionModel(model) {
                    @Override
                    protected boolean areSiblingsSelected(TreePath path) {
                        return path.getParentPath() != null && super.areSiblingsSelected(path);
                    }
                };
            }
        };


Thanks,

[RajaRajeswari_V]

but as per my knowledge areSiblingsSelected(TreePath path) method is private right?.then the following code will give the error.please clarify

[JIDE Support]

It was changed to "protected" since 2.6.7 to implement this class. I have tested this code before I post it. Please give it a try.

Thanks.

[RajaRajeswari_V]

its working fine.but it is giving problem when i unselected the filtered item..

For example

Child1
Subchild1
Subchild2
Subchild3


step 1: select child1 it will selects all the childs...

step 2: search for subchild3

step 3: Then it will display child1>subchild1 with selected state..

step4 : then unselect selected state for subchild 1 and search for different sub child ..then all the subchilds are unselected

Please help me out

[JIDE Support]

It is as expected. It also happens if you use normal table selection model. We don't have a mechanism to restore the selection before filtering so far and I'm afraid we will not have a short term plan for this either.

Thanks,

Just so you know, this is fixed in 2.7.0 which was just released.

Thanks,

Hi ,
I am facing a similar issue .When I make selections in my Checkboxtree and type something in the search panel,the tree changes .When i clear the text in the search panel the tree reappears but the selections disappear . I tried with jide 2.8.5
and 2.6.1 but of no use.
Please help me with this.

[JIDE Support]

We will fix it in both 2.8.6 and 2.9.0.

Thanks,

[vibhor]

Hi,
In the thread below, you have mentioned that it is fixed in 2.7.0 but it is still giving the same issues. Please let me know when this can be fixed or suggest some workaround.

[JIDE Support]

Sorry for the confusion. However, we did mention the NPE issue which was fixed in 2.7.0. Please check out the change log for 2.7.0 at http://www.jidesoft.com/history/. In the previous post, you would see that we didn't find a good solution for this issue at that time.

(Grids) Fixed the NPE issue while selecting the last node while CheckBoxTree implements FilterableCheckBoxTreeSelectionModel.

Thanks for triggering this issue out again. We were able to re-consider this issue and figured out a solution eventually. Will let you know when 2.8.6 or 2.9.0 is released. They should be ready in two weeks.

Thanks,

[JIDE Support]

Just so you know, 2.8.6 is released. In this release, if you use FilterableCheckBoxTreeSelectionModel, the issue vibhor raised has been solved.

Thanks,

[vibhor]

Hi,
I downloaded the 2.8.6 version of jide. I tried running a simple example by making some changes in the G15.QuickFilter example.I changed the tree to CheckBox Tree and changed the selectionModel to FilterableCheckBoxTreeSelectionModel. Two Observations:

1) There is a treeModelListener attached to the tree which updtaes the label whenever the tree is filtered. The selections are retianed only if i use this. If i remove it the selections are gone. Please help me understand what does this code exactly do.

2) When i set the digIn to false and filter the tree , i am able to select/deselect the Child

POC.java

(6.67 KiB) Downloaded 2185 times

but not the Parent . It was not the same in earlier version. If my tree is:

*Root
->First
->Second
->Third
->Child1
->Child2
->Child3

If i filter Child1, then i am able to select/deselect Child1 but not its parent(Third). Please help me with this.

Thanks
Vibhor
