I'm trying to set the assigned value to a YUI Menu Button in order to use values from previous operations.
Something like remembering previous choices.
For label I already know that I can change it with:
button.set("label", "my label")
unfortunatelly I cannot change the value using: button.set("value", "my value")
Any ideia on how can I do this?
Other way would be to force a selection, but I have no ideia on how to do that.
Thanks
just found out that you can use:
var menu = button.getMenu();
var item = menu.getItem(index);
button.set("selectedMenuItem", item);
all that is left for me now is finding the needed index

I am making a battleships program, and after i created a list of identical buttons for a grid and inserting them all into one list, i want to be able to choose the button just clicked and delete it. How can i achieve this?
l = []
for i in range (100):
b = Button(battleship.frame, height = 1, width = 3, command = )
l.append(b)
#this is a snippet of what i have now but i am not sure what to do.
I have tried using lambda to give each button something unique to make them all different but i don't think this helps me in selecting the specific button that was just clicked.
Any suggestions?
While adding component dynamically, 'this.container is null' is displayed in firebug.
I have a window with some combo boxes say combo1, combo2, combo3 and a label. Based on the selection value of combo3 the 'label' field is removed and replaced with combobox or text field. i do this my using
form.items.removeAt(4);
form.items.insert(4, newItem); #here newItem can be combox/textfield
form.doLayout();
The form resides inside a panel.
When above lines are execueted. 'this.container is null' is displayed and component fails to insert/add in appropiate position.
Any suggestions?
You should not be modifying the underlying items collection. Use the remove/insert methods on the container.
Try to comment those lines line-by-line to see which one produces error like
form.items.removeAt(4);
//form.items.insert(4, newItem); #here newItem can be combox/textfield
//form.doLayout();
form.items.removeAt(4);
form.items.insert(4, newItem); #here newItem can be combox/textfield
//form.doLayout();
form.items.removeAt(4);
form.items.insert(4, newItem); #here newItem can be combox/textfield
form.doLayout();
Your problem could take place because of inserted/replaced object is no yet prepared when you try to insert it. Give us your newItem initilization code.

Or you can wrap your changing components (label, combobox, textfields) in a panel with card layout. And on change of combo3 simply select exact card in that panel.
I was wondering if it was possible to replace one control in a TableLayoutPanel with another at runtime. I have a combo box and a button which are dynamically added to the TableLayoutPanel at runtime, and when the user selects an item in the combo box and hits the button, I'd like to replace the combobox with a label containing the text of the selected combo box item.
Basically, if I could simply remove the control and insert another at it's index, that would work for me. However I don't see an option like "splice" or "insert" on the Controls collection of the TableLayoutPanel, and I was wondering if there was a simple way to insert a control at a specific index. Thanks in advance.
Fixed this by populating a panel with the two controls I wanted to swap and putting that into the TableLayoutPanel. Then I set their visibility according to which I wanted to see at what time.
This is what I've been able to come up with for what I needed. It gets the position of the ComboBox and makes a new label using the selected value.
// Replaces a drop down menu with a label of the same value
private void lockDropMenu(ComboBox dropControl)
{
TableLayoutPanelCellPosition pos = myTable.GetCellPosition(dropControl);
Label lblValue = new Label();
myTable.Controls.Remove(dropControl);
if (dropControl.SelectedItem != null)
{
lblValue.Text = dropControl.SelectedItem.ToString();
lblValue.Font = lblValue.Font = dropControl.Font;
// Just my preferred formatting
lblValue.AutoSize = true;
lblValue.Dock = System.Windows.Forms.DockStyle.Fill;
lblValue.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
myTable.Controls.Add(lblValue, pos.Column, pos.Row);
}
}
I would like to move "click heading to sort" to "double click heading to sort". So currently i'm doing it with the following two lines:
table.unsubscribe("theadCellClickEvent", TAG.content.table.onEventSortColumn);
table.subscribe("theadCellDblclickEvent", TAG.content.table.onEventSortColumn);
However, when i do this, and i click on the heading, it will take me to folder/thead-id (since by default there is a "a" tag wrapped around the heading text.
Any idea how to do it properly?
Thanks a lot!

You have to stop the default click event. Create a new event handler for the click event that simply stops bubbling the event.
var stopEvent = function(oArgs) {
var evt = oArgs.event;
YAHOO.util.Event.stopEvent(evt);
};
table.unsubscribe("theadCellClickEvent", TAG.content.table.onEventSortColumn);
table.subscribe("theadCellClickEvent", stopEvent);
table.subscribe("theadCellDblclickEvent", TAG.content.table.onEventSortColumn);
I've been playing around with this for a couple of weeks now with no success...
In a CKEditor dialog, text input fields are renamed with a unique number - e.g. id: 'txtUrl' will become something like id='27_textinput'.
How do I reference this?
// I feel it should be something like:
var myfield = CKEDITOR.instances.myElement.document.$.body.getId('txtUrl');
// or maybe:
var myfield = CKEDITOR.dialog.getContentElement('info','txtUrl');
// and then:
myfield.value = 'myvalue';
But these don't work. Please help! Thanks in advance, R
This was the final solution:
var dialog = CKEDITOR.dialog.getCurrent();
dialog.setValueOf('info','txtUrl',"http://google.com");
return false;
within an onchange part of an element I now use
dialog = this.getDialog();
alert(dialog.getContentElement('info', 'grootte').getInputElement().$.id);
and it gives 'cke_117_select' as a result. (It's a selectbox)
alert(dialog.getContentElement('info', 'txtUrl').getInputElement().$.id);
gives 'cke_107_textInput'.
I think this is what you (or other visitors to this page) are looking for.
You have a page containing the CKEditor 3 and a dialog pop up. You open from this dialog, another pop up window, that is a JSP page. In order to set a value to a field in the dialog of CKEditor's parent window, you do the following:
window.opener.CKEDITOR.dialog.getCurrent().getContentElement('dialogTabId', 'dialogTabFieldId').setValue('yourValue');
This applies to CKEditor 3.
Look at the api dialog sample:
// Get a reference to the "Link Info" tab.
var infoTab = dialogDefinition.getContents( 'info' );
// Set the default value for the URL field.
var urlField = infoTab.get( 'url' );
urlField['default'] = 'www.example.com';
get
var ckValue = CKEDITOR.instances['txtUrl'].getData();
and set
CKEDITOR.instances['txtUrl'].setData(ckValue);
