Check boxes inside tree

Is it possible to add check boxes inside Tree as elements. Can anyone please provide some sample code for that?

Hi,
Unfortunatly all is correct in your code, except data. CheckBox should know when it should be checked and when not. and what should be chnged when you click on it. It's only show data. For changing data you showl add logic to handle click event on CheckBox.
<mx:XML id="dgData">
<root>
<item col1="1" col2="sdf"/>
<item col1="0" col2="sdfa"/>
<item col1="0" col="wer"/>
<item col1="1" col2="dgh"/>
</root>
</mx:XML>
<mx:DataGrid x="171" y="137" editable="true" dataProvider="{dgData.*}">
<mx:columns>
<mx:DataGridColumn headerText="Column 1" dataField="col1">
<mx:itemRenderer>
<mx:Component>
<mx:CheckBox selected="{data.@col1 == '1'}"/>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
<mx:DataGridColumn headerText="Column 2" dataField="col2"/>

Check Box in Tree (tree multiple selection)

I need to create a 2 level hierarchy tree, where the user is allowed to make multiple selection on leaf node. One way is to use TableTree (TreeByNestingTableColumn), but with this I am unable to get the same look and feel of a simple Tree view.
My questions are:
1. Is there a way to enable multiple selection on a simple Tree?
2. If the answer to question 1 is no, then is there a way to add check boxes to the Tree elements (be it parent or leaf)?
3. Is there anything that can be done to solve this issue without using TableTree?
Thanks in advance.

Hi,
Please go through Multiselection in Tree control thread.
The solution outline is like this:
1. When you click on a leaf, you mark it as selected and you can also store it in the context.
2. Click as many leaves as you like and the onAction will mark each of them as selected.
3. There's no need to do a CTRL+click, only normal clicks.
4. Once done you can find out all the marked leaves.

Check box in Tree ui element.

Hi All
I am using org.eclipse.swt.widgets.TreeItem for creating tree structure. Now I am trying to incorporate check box for last tree element. For example if I am preparing tree structure for files the check box should appear only for text file not for directory. User would select the file by checking the box. Here is my code..
for (int i = 0; i < files.length; i++) {
TreeItem item2 = new TreeItem(item1, 0);
item2.setText(files.getName());
item2.setData(files[i]);
if (!files[i].isDirectory())
//here i have to do some thing so that i can select the file in check box
if (files[i].isDirectory()) {
new TreeItem(item2, 0);
I cant use java script here. So pls help me out without using js.
Thanks a lot.

in oninputprocessing use the following code to read all the form field values

field type ihttpnvp.
call method request->get_form_fields

Check Box in Tree Control

I found that the oracle installation is using tree control with check box. I tried to use the same feature in my application. But I found that the tree control in swing and infoswing is not having the feature to add checkbox in the tree control. If anybody knows how to add checkbox in the tree control using the jdeveloper please help me.

You can see how to do it the next link http://www2.gol.com/users/tame/swing/examples/JTreeExamples2.html

Why does the check box untick itself?

I have a program which has a GUI control that I designed. It consists of several check boxes inside a panel, the user can tick one or more of them. There are various methods to get all the selections, untick boxes in code etc. In one place in my software, I need a dialog box to appear when the user ticks a box. So I got my control to raise a property change event whenever one of the check boxes is ticked or unticked. I then catch this in another part of the code, and cause a dialog to appear which asks the user for further options.
My problem is this: for some strange reason, when the dialog appears, it is causing the check box to be unticked again immediately after it is ticked. I have prepared a simplified version of the problem code, below. If you comment out the call to ticking(), then it works ok (but the dialog doesn't appear obviously). Has anyone got any ideas, please?

Help - how to change Check Box color?

Hi All!
Can anyone help and tell me how to change the color of a Check Box (inside the little square where users check or un-check) from the default white color to, say, gray?
Thanks in advance.

Can i have a check box in the hierarchical tree in the icons place, urgent!!! please

Hi,
I'am working on the Hierarchical Tree structure which should have three levels, I need to have a check box in the place of the icon & if i select a node that node & the child nodes should get selected.
After this when i say move selected ( i'am trying to use picklist class also) the entire checked tree has to move to the display area to the right & should display as tree structure & after this if i save then the checked records which are moved to another text area should get saved!!
How to achieve this? I have the tree structure ready but the check box part is the worrying factor! & then moving the checked records to the right using picklist class is the second problem & finally saving records to database.
Any help in this regard will be deeply appreciated:)
If check box is not possible then i will have to look at other methods, will the tree structure allow checkboxes????
Thanks
Mahesh

No the tree will not allow checkboxes

How to handle check box events in alv tree.

hi,
i am working in CL_GUI_COLUMN_TREE class.Also using Check box. Now i want to handle events for check box . I am new to ABAP Objects.
Pls expaline in detail or send code
thanks in advance,
senthil kumar.r

Hello Senthil
Have a look at the sample report
SAPCOLUMN_TREE_CONTROL_DEMO
. The crucial points are:
(1) Register the required events at the control
* define the events which will be passed to the backend
" checkbox change
event-eventid = CL_GUI_COLUMN_TREE=>EVENTID_checkbox_change.
event-appl_event = 'X'.
append event to events.
CALL METHOD G_TREE->SET_REGISTERED_EVENTS
 EXPORTING
 EVENTS = EVENTS
 EXCEPTIONS
 CNTL_ERROR = 1
 CNTL_SYSTEM_ERROR = 2
 ILLEGAL_EVENT_COMBINATION = 3.
IF SY-SUBRC <> 0.
 MESSAGE A000.
ENDIF.
(2) Set the event handler
assign event handlers in the application class to each desired event
SET HANDLER G_APPLICATION->HANDLE_CHECKBOX_CHANGE FOR g_tree.
(3) Define and implement event handler method
METHOD HANDLE_CHECKBOX_CHANGE.
 " this method handles the checkbox_change event of the tree
 " control instance
 " show the key of the node and the name of the item
 " of the clicked checkbox in a dynpro field
 G_EVENT = 'CHECKBOX_CHANGE'.
 G_NODE_KEY = NODE_KEY.
 G_ITEM_NAME = ITEM_NAME.
 CLEAR G_HEADER_NAME.
ENDMETHOD.

Check Box Tree.

Hi All,,
Unfortunately, I knew that the Check box Tree was removed from the final release of Apex, but I have a problem and I do need to implement this functionality in my application. What I have tried so far is :
1- I tried to use Apex_Item.Check Box in the ICON parameter of the tree query, but nothing happened.
2- I tried to concatenate Apex_Item.Check Box in the Text parameter of the tree query, but it displayed as a normal text and the browser doesn't interpret the html text <input type="check box".....>.
Does anybody now any solution or work around for this problem?
Any help will be appreciated.
Thanks in Advance,,
Ola

ADF Tree with Boolean Check Box: How to find selected items

Hi Experts,
ADF: 11.1.1.5.0
WLS: 10.3.6
I am using an ADF Tree which contains elements at two levels (say Departments and Employees). My requirement is to give provision for user to select Departments and Employees using the check boxes. User should be able to select what ever Departments he/she likes and what ever employees he/she likes. There should not be a provision to select Employee with out selecting the corresponding Department (root node in the tree).
I am facing the below issues while trying to implement this use case:
1. Always, only the first master record will be expanded by default (I am using "Display Row" property value as "default" and "ExpandAllEnabled" as "true"). My need is to expand all the master records by default. So that user need not explicitly expand each master record node and then select the associated child records.
2. Currently, I am using value change listener associated to af:selectBooleanCheckBox to identify the Departments and Employee records that have been selected. Since not all departments (masters) are expanded by default, if user selects the check box of department (master) and then expands the department node, automatically all the employees of that department are selected. But, this event is not triggering the value change listener for the employee records. Because of this, after a department node is selected and then expanded, all the child elements' check boxes are selected but the events are not generated. Hence, I am not able to capture the selection of employee records.
To summarize,
1. Please let me know how to expand all master nodes in af:Tree by default.
2. Please let me know the best approach to identify the selected items (both master and detail items) in the af:Tree component using af:selectBooleanCheckBox.
Thanks in advance,
Rathnam

Using check Box in a Tree Region style

I want to display some data in a hierarchical manner and use a checkbox for the user to select the node for which he wants to see a report.
I need to fetch the node value where the user has ticked in the check box.
I went through the documentation but it does not mention about using a checkbox.
Can any one please let me know if we can use checkbox to tree nodes and to capture the user checked nodes do we have to make the VO based on an EO or even with a read only VO I can know which node the user has selected.

Hi,
In my project i need to use Check box in <af:tree> so that i can select some tree nodes .Has anyone tried it before?. any pointers regarding this would be helpful for me.
thanks in advance,

Hi,
Maybe you need to set a partialTriggers in af:selectBooleanCheckbox, referencing to clear button.
Anyway, see this Andrejus' article, perhaps you can on it a better way to achieve that: http://andrejusb.blogspot.com.es/2011/12/adf-tree-how-to-autoselectdeselect.html
