Disabling selection of JSeparator in a JComboBox

Does anyone know how to disable the selection of a JSeparator in a JComboBox?
I'm using JRE 1.1.8.

The BlockComboBox example doesn't allow the selection of the separator, however there is no way to move past the separator by using the arrow keys of the keyboard.
I've tried to add a key listener, but for some reason the code never gets executed when hitting a key.
Is there a problem with using key listeners with a JComboBox?

How to disable selection of root node in JTree

Hi all! Thanks for taking a minute to read my post!
I am writing a really basic JTree for showing a list of items.
Here is some of the code:
/** Create a basic tree **/
DefaultMutableTreeNode rootNode = new DefaultMutableTreeNode("Title");
DefaultTreeModel treeModel = new DefaultTreeModel(rootNode);
JTree tree = new JTree(treeModel);
/** Method to return the string of the current highlighted selection **/
public String getSelectionString()
DefaultMutableTreeNode node =
tree.getSelectionPath().getLastPathComponent();
return (String)node.getUserObject();
I would like to disable selection of the root node of my JTree.
Thus, if I make a call to getSelectionString() above, it would return null instead of the string that represents the root label.
I have read the following forum on disabling various TreePaths and TreeNodes in a JTree:
http://forum.java.sun.com/thread.jsp?forum=57&thread=224691
This forum suggests implementing the TreeSelectionListener interface and the TreeSelectionModel class and over-riding the addSelectedPath() methods. I tried this suggestion, and I was able to enable and disable the different children of the Jtree, but the root of the JTree would not disable.
I suppose that I could just simply remove the visibility of the root node, but I really want to avoid that option if possible.
Wait --- let me be clear ---- I want to disable the selection of the root node only - still allowing selection of all its children.
Any suggestions?
Am I missing something really simple here?
Did I explain my problem clearly?
Thanks in advance!
jewels

simply try this..
in the
public void valueChanged(javax.swing.event.TreeSelectionEvent event);
method of TreeSelectionListener impelentation get the
TreePath tp = event.getPath();
from TreePath get the component and then remove the selection from the treePath if it is the node u were checking/root node in this case
tree.getSelectionModel().removeSelectionPath(tp);
Try out....

Disable select one choice in adf table

Hi, my requirement is that based on value of input text i have to disable select one choice(soc1) in adf table.
suppose i have to disable soc1 on value of input text i have used *#{row.bindings.Dependenttaskid.inputValue=='30'} it's working fine.*
But my requirement is that i have to disable soc1 checking value from two input text
When i am using operator from expresion builder like *#{row.bindings.Dependenttaskid.inputValue=='30'}and#{row.bindings.Tasklocationid.inputValue=='OUTSRC'}*. it is not showing error but it's not working .
Can anyone suggest how to use orperator from expression builder.
Thanks a lot!

you can override isAttributeUpdateable is your viewRowImpl class like this code
public boolean isAttributeUpdateable(int i) {
//you can add your condition here
if (this.getDependenttaskid().equal("30") && this.getTasklocationid().equal("OUTSRC") && i==YouLOVAttributeEnum)
return false;
else
return super.isAttributeUpdateable(i);

How to disable "Selection Security" in a correct way?

hi experts!
how to disable "Selection Security" in a correct way?

thanks!

Hi...
Open "Catalog Manager" and
navigate to Shared -> "Shared Folder Name" (ex: Sample Sales) -> _Portal.
Here you find all dashboards. Open the dashboard that you already enabled selection. In that dashboard folder you find one more folder with name: _selections*
Delete the _selections* folder.
You will get Enable option again in front end.
All the best

Disable selection of certain items in ListView

I have a ListView with different items.
For most items I like the default multiple selection but for some items I would like to disable selection completely.
I tried disabling the cell while it displays a non selectable item, but this only disables selection from direct events on the cell. I can still select it by clicking on an item above an then shift-clicking on an item below.
I also tried to set the cell as empty when displaying a non selectable item. This fixes the issue with shift selection described above, but i can still select the cell by selecting an item next to it and pressing the respective arrow key.
Does anybody have an idea?
Thanks

How about this?
 final ListView<Node> fileList = new ListView<Node>();
 fileList.getSelectionModel().selectedIndexProperty().addListener(new ChangeListener<Number>() {
 @Override
 public void changed(ObservableValue<? extends Number> observableValue, Number oldv, Number newv) {
 if (newv.intValue() == 4) {
 fileList.getSelectionModel().select(oldv.intValue());
 });

How can I disable Select Tool & enable Hand Tool using Adobe JavaScript ?

How can I disable Select Tool & enable Hand Tool using Adobe JavaScript ?
I want wherever the PDF opened automatically preferrence changed, default HAND TOOL remain selected. I want to do it using Adobe JavaScript.

You are correct in that it's not functioning, however I do not have that option under the "online and adobe online" section in Adobe Customization Wizard XI. I have the following boxes that can be checked:
"Disable initiating shared reviews and data collection via distributed forms using Adobe online services (does not affect non Adobe online services reviews and forms).
"Disable the Tools pane in Reader"
"Disable file storage on Adobe online services"
"Enable file storage even when all other services are disabled"

JTextArea / Disabling selection

Im getting a bit frustrated with this, hence my post....
I have a JTextArea, in which will contain various text.
The component should not be editable, and likewise should not be selectable.....
I still have not found a way to disable text selection in a JTextArea, in fact any subclass of JTextComponent for that matter.
why setEnabled(false) does not prevent selection is beyond me........
I had a similar problem once before, and my solution was to set selection color to thed, which worked just fine, despite not really solving the problem....
I would probably go ahead and use this technique again, however I have a different situation here, Im using a translucent background, (0,0,0,0) and setting selection color to this value does not seem to work...
Is there a way to totaly disable selection???
Should I possibly use a different component to handle the task, which does not support selection, ( Ihavent found anything yet). I need to have line wrap so a few of the more basic components are out of question....
Im hoping some would give me some suggestions on this, they will be greatly apreciated, and as always adequately rewared....
Thanks

I had a non-editable JEditorPane which I didnt want to select its text, if I'd set it to setEnabled(false) whenever I would've cross a hyperlink, The cursor would not change to a Hand-Cursor (because the comp. is disabled)
So, What I did was just "disabling" the selection (not the comp.) by setting my own Caret as follows:
        JEditorPane lbl = new JEditorPane();
        lbl.setCaret(new javax.swing.text.Caret()
            public void install(javax.swing.text.JTextComponent c){}
            public void deinstall(javax.swing.text.JTextComponent c){}
            public void paint(Graphics g){}
            public void addChangeListener(ChangeListener l){}
            public void removeChangeListener(ChangeListener l){}
            public boolean isVisible(){return false;}
            public void setVisible(boolean v){}
            public boolean isSelectionVisible(){return false;}
            public void setSelectionVisible(boolean v){}
            public void setMagicCaretPosition(Point p){}
            public Point getMagicCaretPosition(){return new Point(0,0);}
            public void setBlinkRate(int rate){}
            public int getBlinkRate(){return 10000;}
            public int getDot(){return 0;}
            public int getMark(){return 0;}
            public void setDot(int dot){}
            public void moveDot(int dot){}
        });Again I remind you that this will only work good for non-editable text components...
Cheers

Bex 2004s - Disabling Selection Sreen of a Query for the purpose of Views

Hi,
Is there possibility in Bex 2004s, where in we can disable Selection Sreen of a Query for the purpose of creating multiple Views.
Thanks
Praveen

Hi,
There is no posibility to disable the selection secren if there are any variables defined on a query. it can be done on the web applications side by inserting the command VARIABLESCREEN=" ". in this also it is only possible if there are no mandatory variables defined on the query.
thanks

Disabling selecting label text

Hi
I just noticed that by pressing on a label on a touch screen devices the text become selected. Only way I found was to cover the label with rectangle. However the rectangle reduced gallery performance specially on surface2 device. So is there
any solutions to disable selecting text without disabling whole label? I'm using label OnSelect behaviour so I can't disable whole label

Hello,
Similar for round buttons which look "smart" when developing for touch.
For now I duplicate the function in the label and the shape but that's removing some of the cooler effects you can default on a button (press, etc.)
