Programmatically select a sketcher at runtime

Hi !!
We have two editor named MDL editor and ISIS editor installed in the system. Actually, I have to open the editor programatically. We have developed a eclipse plug-in for that and that is working fine. The issue is when I selected the ISIS editor in eclipse environment and make the call, then every time MDL editor is get opened. How can I select the editor at run time. If you guys have any idea then please do help me.

Pop up a dialog and ask which the user wants...
or you are going to have to choose the default one that you want used and search the system to see if it is installed.

Programmatically selecting row in af:table

I have an instance of the <af:table> component that points to a value on a managed bean of type List<MyValueType>.
I need to make the <af:table> have a preselected row, and I have the value of type MyValueType that represents the row I need selected.
How do I programmatically select the appropriate row in the table?
Thanks!

Hi Rune,
1) Expose the adf table to a managed bean property by using @binding attribute, say, requestScope. The property should be RichTable type.
2) Create a method in java class which can find the managed bean created in step 1) by using EL expression and calling its RichTable.setRowKey(int) to set the current row. Other row currency method are also available besides setRowIndex(int).
3) Create Data Control on the java class you created in step 2)
4) Insert the method created in step 2) into <bindings> as methodAction in page definition file.
5) Still in page definition file, insert an invokeAction into <executables> to invoke the method action created in step 4)
6) Reorder the invokeAction created in step 5), place it below the table's <iterator>
7) Set the @refresh attribute for the table <iterator> and <invokeAction> if you want, for example: "prepareModel"
-Or-
You can implement a custom page lifecycle to achieve the goal.

Programmatically selecting a cell in a two-dimensional JTable

The problem is that when a person edits a cell and the value fails validation, I would like to programmatically select the cell. The validation is done in the setValueAt method of a Class extending the AbstractTableModel. By simply returning out of that method, the cell value is set back to the way it was before the user changed it. In addition, I would like the problem cell to be automatically selected rather than requiring the user to click in it to select it. The first question is 1- Is this possible, and 2- Any clues as to how to select it?
We find for examle in Chapter 6 of the CoreJava 2 Vol II Advanced features statements like this on page 399 of, I think, Edition 4, (can anyone tell what edition it is?) by Cay Horstmann
void setCellSelectionEnabled(boolean b)
If b is true, then individual cells are selected (when the user clicks in the cell?). I have researched this problem for several days and don't have a clue how to automatically select the cell although I know precisely what row and column it is.

This is the code to return the focus to error cell.

Programmatically selecting Item in drop down

I want to Programmatically select an item in a dropdown when the page is loaded. I am using the following code:
<h:selectOneMenu binding="#{CatByLocTrend.predefinedQueryDropdown}" id="predefinedQueryDropdown"
style="height: 21px; width: 133px; font-family: Verdana,Arial,Helvetica,sans-serif; font-size: 10px" valueChangeListener="#{CatByLocTrend.predefinedQueryDropdown_processValueChange}">
<f:selectItems binding="#{CatByLocTrend.predefinedQueryDropdownSelectItems}"
id="predefinedQueryDropdownSelectItems" value="#{CatByLocTrend.predefinedQueryDropdownDefaultItems}"/>
</h:selectOneMenu>
I use the following to select the item after the default values have been loaded:
predefinedQueryDropdown.setValue(new Integer(2));
predefinedQueryDropdownSelectItems.setValue("Top3Sales");
Neither of these work. How do I programmatically select the value?

I have this working.
Following is some code snippets:
JSP:
<h:selectOneMenu binding="#{Admin$AdminEscalationList.uiSelOneMnuMgrList}" id="dropdown2"
                            style="left: 443px; top: 349px; position: absolute; width: 186px" value="#{Admin$AdminEscalationList.currMgrSelection}">
                            <f:selectItems id="dropdown2SelectItems" value="#{Admin$AdminEscalationList.escalationContntMgrs}"/>
</h:selectOneMenu>Now is the Code behind it:
Java:
    private UISelectOne uiSelOneMnuMgrList = new UISelectOne();
    public UISelectOne getUiSelOneMnuMgrList()
        return(uiSelOneMnuMgrList);
    public void setUiSelOneMnuMgrList(UISelectOne oNewVal)
        uiSelOneMnuMgrList      = oNewVal;
    private int m_nMgrId        = 0;
    public Integer getCurrMgrSelection()
        return(new Integer(m_nMgrId));
    public void setCurrMgrSelection(Integer strMgrSelection)
        try
            m_nMgrId            = strMgrSelection.intValue();
        catch(Exception ex)
// Now is the function that pre-set the selection of the list.
// Call the below function in whereever you want to set the preselection.
uiSelOneMnuMgrList.setValue( getCurrMgrSelection());Of course, I am calling the setCurrMgrSelection() before calling the
uiSelOneMenuMgrList.setValue() function.
Let me know if any of you have any trouble with this.

Programmatically select a property

Hello,
Is it possible to programmatically select a property for a FP object? Properties for which a value change is required are stored in a database (as are the values itself). I can't use a property node because the poperty to change is not fixed and the database can and will be extended in near future.
Thanks.
Jan

That looks to be a very powerful library of VI's that you have linked to tst.
It looks like they've basically enumerated all the possible properties for all the control types. They some tricky combination of names and tags and the properties saved as binary data and can parse the file they have to determine which VI's to run and which cases of all the case structures to execute to get to the appropriate property node.
I'm going to hold on to this library as it could be very helpful in the future.
I dug into the VI's to see how they were doing this. I came across a property node with a pink top bar instead of the usual yellow, and I've never seen this before. What does it mean?

JTable - Programmatically selection multiple cells

Hi!
I'd like to know wether it's possible to programmatically select certain cells of a Jtable component.
For example:
My Jtable looks like that
1 2 3
4 5 6
7 8 9
and I want to select cell 2,4 and 7. How could I do that??
Thanks for answers...

Hello,
I consciously read your thread, but I still can't get the sample code running.
(java.lang.StackOverflowError
Exception in thread "main" )
Would you please give me a hint?
Or better,
send or post me the sample code of your class 'AttributiveCellTableModel', please.
Thank you very much in advance!

Distinguishing user selections from programmatic selections in JList

I have two jlists., and registered a subclass of ListSelectionListener on each list. When the user selects a record in the first list part of of the code I have written sets a selection on the second list which is correct, but then this triggers the listener on the second list to receive an event, and run its listener code which is not what I want.
I want to be able to identify a list selection caused by the user selecting a record in the list rather than the a programmatic selection, so that i can ignore programmatic selections.
Checking event.getSource() is no good as it always just returns the JList itself regardless of whether it has been done programtaically or by a user.
I tried checking list.isFocusOwner() , figuring that only lists that had been user selected would be focus owner. This works for Windows but on MacOS, it doesnt work the frst time you select something from the list after moving from another component (it does work after that).
How do i do this, thanks Paul

an alternative is to set a flag
boolean fromList1Listener = false;//class field scope
list1Listener
fromList1Listener = true;
change list2 selection
fromList1Listener = false;
list2Listener
if(fromList1Listener == false)
normal code goes here

ADF Tree (10.1.3) Programmatically select Tree node

Hi,
i want to pre-select a specific treenode in an af:tree programmatically. I got it nearly working with using a CoreTree-binding in the backing bean using set setFocusRowKey method. After that, the node is selected properly, but when selecting another node in the tree via the UI, the programmatically selected node is not deselected, means in the display is see two selected nodes.
Any ideas ?
Tia,

Programmatically selecting a Tree node

Hi there,
Given a TreePath object, I need to know how to programmatically select a tree node on a JTree.
Here's the situation:
I have a simple text editor project which has a JTree on its interface representing the local file system. The program has a SaveAs dialog box which also has a duplicate JTree as the one on the main interface (directories only). As the user selects the directory in which they wish to save the open file in the SaveAs dialog box, I need somehow to programmatically cause the JTree on the main interface to correspondingly select the same directory. How is this done?
The whole point of this is so that I can then add a new leaf node to the tree at the specified directory location. I've tried simply setting the jTree1.setSelectionPath(...) method and even tried to call the valueChanged(...) method of the TreeSelectionListener object as you can see from the code snippet below, but none of these approaches have been successful.
Please advise,
Alan
public void createLeafNode()
     jTree1.repaint();
     if(path == null)
        return;
     jTree1.setSelectionPath(path);
     //SelectionListener.valueChanged(new TreeSelectionEvent(jTree1, path, true, oldLeadPath, newLeadPath));
     //System.out.println("path is: " + path.toString());
     DefaultTreeNode parent = getTreeNode(path);
     //System.out.println("parent is " + parent.toString());
     //Create the child node
     IconData idata = new IconData(ICON_LEAF, new FileNode(new SpecialFile(ref.FileOpen)));
     DefaultTreeNode node = new DefaultTreeNode(idata);
     parent.add(node);
     //Tell the model that the tree structure has changed
     model.nodeStructureChanged(parent);
     path = path.pathByAddingChild(node);
     jTree1.scrollPathToVisible(path);
     //jTree1.repaint();

Yes, I've tried setSelectionPath(TreePath path) numerous times, but it does nothing to select the node on the tree! You can see from the code I submitted that it is there commented out.
Ordinarily, when you click on a node on the tree it becomes the "active" node, evident because it becomes highlighted. But when I use setSelectionPath(TreePath path) method, giving it the path it needs, the node on the tree doesn't become the "active" node, therefore, not selected! Furthermore and subsequently, the rest of the code in the method createLeafNode() doesn't add a new node to the tree in the location specified by the TreePath object!
If you have used setSelectionPath(TreePath path) before successfully I would be interested in seeing a small sample program demonstrating its use. It would have to prove to me that you can select a node in the tree without physically clicking on any node in the tree with the mouse cursor, and add a new child node to that selected node.
I submit to you a small test program I put together that demonstrates the "typical setup". It requires the user to physically click on a node of the tree, then click on a button that adds a new node in the location of the selected node. If you can alter this program demonstrating that you can add a new node to the tree without my having to click on any node of the tree with my cursor, then I'll assign you the Duke Dollars and be forever humbled by your programming prowess.
Thanks for keeping on top of this thread as I've tried everything I can think of to try and make my program work. If you need to ask any questions please ask away. Perhaps there is something about my program that I've not explained yet that you're not aware of that I should have included. At this point I can't see the forest for the trees.

Programmatically select all items in a list

Hi, I've been looking through the online docs trying to find
a way to programmatically select all items in a list. I have a
checkbox that when checked should select all items in a list. I
found a method to clear all selections but not one to select all.
Did I just miss it? Thanks!

I don't know of any built-in functions to select all list
items, but here is an example function to select all items in a
list:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
xmlns="*" layout="absolute">
<mx:Script>
<![CDATA[
[Bindable] private var people_xml:XML =
<people>
<person>Jen</person>
<person>Brian</person>
<person>Scot</person>
</people>;
private function select_all():void {
var indices:Array = new Array();
for (var i:uint = 0; i<people_xml.children().length();
i++) {
indices.push(i);
peopleList.selectedIndices = indices;
]]>
</mx:Script>
<mx:Button x="125" y="10" label="Select All"
click="select_all()"/>
<mx:List x="10" y="10" allowMultipleSelection="true"
dataProvider="{people_xml.person}" id="peopleList"

Is there any way to programmatically select photos?

I'd like to programmatically select photographs in a catalog based on the contents of a file (containing image names). Is this possible? Thanks!

If your goal is to run a script that when completed leaves your Catalog in grid mode with certain images selected, i.e., highlighted, then I don't believe there is currently a method available with the SDK. I might be wrong so please wait for others to respond as well.
You can of course scan the entire catalog and perform certain actions for images meeting your criteria (containing image names) if that is your ultimate goal. This will entail studying the SDK manual, sample plug-ins, etc. all of which involves learning the lua language to some extent. The SDK has many limitations but I doubt that its functionality is complete at this point so it may be worth your while to start the learning process. I only dabble a bit but find it somewhat fascinating.
Also, you might be able to solicit someone from this forum to write the plug-in for you, for a fee of course. I would suspect a little more information might be necessary.

How do you programmatically select TabBar VC within the MORE section?

Can anyone help me figure out how to programmatically select a view controller that is beyond the main 4 tabs in a TabBarController? Usually you can use:
tabBarController.selectedIndex = NSUInteger;
but once you have more than 5 Tabs, you get the "More" tab as #5 and the others go into their own TableView. If you try to change selectedIndex to any # > 4 you get an NSRange error.
I have tried the following workaround unsuccessfully:
UIViewController *desiredVC = [[tabBarController.viewControllers] objectAtIndex:5];
tabBarController.selectedViewController = desiredVC;
where tabBarController is a UITabBarController;
Still no go. Any help would be greatly appreciated.

I came up with this solution:
[self.tabBarController.moreNavigationController popToRootViewControllerAnimated:NO];
[self.tabBarController setSelectedIndex:4];
[self performSelector:@selector(selectMore:) withObject:newViewController afterDelay:0.1f];
- (void) selectMore:(UIViewController *)controller
[self.tabBarController.moreNavigationController pushViewController:controller animated:NO];
It's does the job, but the "More..." list is shortly displayed before the newViewController is displayed.
Is there another way to handle this problem?

Programmatically selecting one NI-9505 module from a PXI R-series expansion slots

How can I
change the SoftMotion example entitled “position control closed loop- NI
9505.lvproj” in order to use it as a
configurable sub-vi to drive serveral motors?
in a PXI-RT
box I’m using a PXI-7813R card, its ports are connected to several R-series expansion
chassis’s each of them driving three
9505 Modules, i.e. 12 motors in total
The problem
is I didn’t find a way to programmatically define which 9505 Module the sub-vi
should use, i.e which motor to drive. Is there a way to archive this?
thank you.

Hello Mr. Villa,
as the current and position control portion of your code needs to get implemented on the FPGA. That means, that the code needs to be mapped to the gates of the FPGA, which doesn't allow dynamical assignment of resources at runtime. So in your case you will have to implement the code for one axis and create multiple instances of it with modified I/O nodes for each axis. In contrast to the design rules of standard LabVIEW vis, you should work with a quite flat vi hierarchy with LabVIEW FPGA in order to save FPGA space.
Kind regards,

Programmatically selecting a tab in panelTabbed

Hi,
i have the following UI structure.
af:paneltabbed
---af:iterator
-------af:showdetailitem
As you can see, i have the showdetailitem inside the af:iterator. so am currently in one particular tab, on click of a button i need to programmatically show other tab and close the current tab.
How this can be done in this case?

Can you please check this thread:
Re: How do I select a Tab in a ManagedBean?

How can I programmatically select row to edit in ADF - 11g

Hello,
I'm having a table with rowSelection="single" and editingMode="clickToEdit". Currently i'm facing two issues.
First issue: the first click on a table row makes the row selected, on second click it becomes editable. If I click on another row it gets selected, but previously selected row remains editable. I would like to change this, so when I select another row, the previously selected one to become read-only again. By now, I didn't find any solution to set programmatically the 'editable' state of a row.
The second issue might be a bug and is related to deleting an editable row. I select a row, click to edit it, and then delete it. The next row get's selected, but clicking on it to edit, has no effect unless I press the 'ESC' select another row before. Does anyone have a tip how to workaround it?
Thank you very much!

try adding this method in the table selectionListener.
public void table1_selectionListener(SelectionEvent selectionEvent) {
    public String getCurrentRow() {
        BindingContainer bindings = getBindingsForDCB();
        RichTable table=table1;
        DCIteratorBinding outListIter = getBindingsForDCB().findIteratorBinding("outlistOutIterator");
        RowKeySet rowSet = table.getSelectedRowKeys();
        Iterator rowKeySetIter = rowSet.iterator();
        while (rowKeySetIter.hasNext()) {
                List l = (List) rowKeySetIter.next();
                Key key = (Key)l.get(0);
                outListIter.setCurrentRowWithKey(key.toStringFormat(true));
                Row r = outListIter.getCurrentRow();
        return null;
    }
