I have kendo grid with column re-sizable option. When I double click on column header that column should re-size to auto width (ref:"jsfiddle.net/YF7ny/").
I need this options through MVVM (Model-View-View Model). I am new to this kendo & mvvm concepts, please help me.
To add your double-click handler you would need to make a custom MVVM binder.
There is some documentation on making a custom binder here: http://docs.telerik.com/kendo-ui/getting-started/framework/mvvm/bindings/custom
Then your grid element could have something like
data-bind="gridColumnResize: x"
Another alternative is to extend the default Grid widget and make your own, and in the init you can add your double-click handler.
Since this is JavaScript, you could even overwrite the existing Kendo Grid widget and add this feature to all grids.
I am trying to define a combobox that shows as items, custom controls instead of standard text only items. The control used is com.google.gwt.user.client.ui.ListBox (standard GWT control) as combobox.
Looking at the Showcase http://gwt.googleusercontent.com/samples/Showcase/Showcase.html#!CwCellList for example, there is a custom list with custom items. To do this, the example uses the CellList class. Is it possible to use the same technique for a combobox?
More in general, is it possible to use a combobox with custom, complex items (e.g. multi column items, custom complex items of any sort, in general a widget of my own or similar)?
I ask this using standard gwt ui controls, no Ext-GWT, no Smart GWT or others.
Thanks.
You cannot style GWT ListBox as it translates to HTML <select> element. If you still insist on feature rich combo-box like GXT then you can go with
GwtChosen - http://dev.arcbees.com/gwtchosen/
CellList with reduced height, selection mode - single and CustomCell.
GWT SuggestBox - http://gwt.googleusercontent.com/samples/Showcase/Showcase.html#!CwSuggestBox
I need to create a custom component which can have Label then Textfield and Image, by clicking the image i should select date, that selected date should be populated in TextField,
Is there way i can develop a custom component.
Thanks in Advance!!!
Absolutely!
You need to create a custom widget, and the way to do that is to extend the Composite class.
From the documentation:
A composite is a specialized widget that can contain another component (typically, a Panel) but behaves as if it were its contained widget. You can easily combine groups of existing widgets into a composite that is itself a reusable widget. Some of the UI components provided in GWT are composites: for example, the TabPanel (a composite of a TabBar and a DeckPanel) and the SuggestBox.
Rather than create complex widgets by subclassing Panel or another Widget type, it's better to create a composite because a composite usually wants to control which methods are publicly accessible without exposing those methods that it would inherit from its Panel superclass.
There is a good example to get you started here:
http://code.google.com/webtoolkit/doc/latest/DevGuideUiCustomWidgets.html
The GWT showcase give an example of somthing similar to what you are looking for along with the source code:
"Date Picker" - GWT Showcase
If you want to develop a custom component, look at #Jon Vaughan's answer!
You may also use third party libraries with widgets, like Ext GWT or SmartGWT. Date picker is one of the base widgets that everyone provides.
I'm trying to build a website similar to kayak.com, at least with respect to how it displays and filters results. I'm using GWT and have built a Composite widget which uses a CellList to display the results.
I'm not happy with how the cells are selectable. I've tried setting the SelectionModel of the CellList to an instance of NoSelectionModel, but that doesn't seem to work. Really, I just want to display some text and a few hyperlinks in each cell and only give the user visual feedback (change the mouse pointer, etc.) when the mouse is over a hyperlink.
See if this works for you:
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/2327336e09ab29d1
Use
cellList.setKeyboardSelectionPolicy(KeyboardSelectionPolicy.DISABLED);
to disable selection on a CellList.
i am using gwt to build my web site.
i would like to create a dropdown/listbox that contains no just text but also images, meaning that in the drop down there will be a what ever widget that ill create.
please advise

You won't be able to do this with a ListBox, because it just creates an HTML < select> element.
You can use a MenuBar that has one menu with MenuItems in it to simulate a dropdown with complex widgets inside it. You will also be able to style the dropdown rather than rely on browser-styled form elements.
Take a look at the Combobox or Suggestion box in Advanced GWT Components.
Another widget is the DropDownListBox in the GWT incubator. I have not used it, but the stated intent is to provide a rich, stylable ListBox. You can pass raw HTML to the addItem() method.
DropDownListBox
it is possible to use Tree inside ScrollPanel, without using nested items
Tree allows TreeItem to be a Widget
