问题 Over the past 5 months we have been prototyping GWT and setting up the infrastructure. WE are using GXT for the widgets with MVP and Command Pattern implementations. However, we are currently looking to do a spike on a ComboBox with autosuggest from a live Database. I would like to do this in the framework of the MVP and Command pattern implementations. Any one out there have any ideas how to go about doing this? 回答1: I solved that using a generic DispatchDataProxy modelled over the Command

问题 I am currently attempting to create an Inno script installer which requests a list of "Web sites" from a user's IIS installation so that the user can select the appropriate website from a combo box list and this list can be used to create a virtual directory in the correct Website location. I need to Generate a list of IIS websites e.g. "Default Web Site" populating a combo box So far I have only been able to achieve installing the virtual directory to a location based on a hard-coded

问题 I try to have a GXT combobox (3.0.1) accepting text I type in it but it keeps deleting it on blur. Isn't it possible to tell the combobox to accept a value that's not a part of its liststore ? PS: setForceSelection(false) doesn't do what I want :) 回答1: The bug mentioned in the comments is focused on ComboBox<String> , since there is a natural mapping from the data the user typed in (aka a String) to the data in the combo (also a String). If you don't have such a natural mapping, the latest

问题 I want to add a combo Box in table cell to provide drag n drop option LWUIT. I have used this option for it .. private String strCmbBox[] = { "1", "2", "3", "4" }; ComboBox comboRdoBox = new ComboBox(strCmbBox); comboRdoBox.setListCellRenderer(new comboBoxRenderer()); TableModel model = new DefaultTableModel(new String[] { "Col 1", "Col 2", "Col 3" }, new Object[][] { {"Row 1",new DefaultTableModel(new String[] { "1" }, new Object[][] { { comboRdoBox }, { "lbl" } }), "Row X" }, { "Row 2",

问题 Is it possible to show combobox (better if it will be extjs combo) in the tab's title? I have created an example on jsfiddle but there are such issues: 1. It is not possible to show combo's options list (mouse click don't work) 2. Tab's height is incorrect (I guess this can be fixed by applying height to the combo). Sample code: new Ext.TabPanel({ renderTo: 'tab-with-combo', activeTab: 0, items:[ { title: 'First tab ' + '<select>' + '<option>Option 1</option>' + '<option>Option 2</option>' +

问题 I want to make a GUI which is dynamic, meaning that the GUI will change depending on the choice which user makes on the combo box. For example, if combo box consists of {English, Spanish, French}, the panel on the bottom of the combo box will change its description language depending on the choice. To do this, I believe I have to do something like clear panel then redraw panel, but I have no idea how. Can someone tell me how to make this happen in details on Visual Studio 2005 C#? Thank you

问题 My problem is that the selected ComboBox item text is not visible on the screen after selecting it with setValue(). Here are some details: Adding items to my CB: combo.getItems().add("a"); combo.getItems().add("b"); combo.getItems().add("c"); combo.getItems().add("d"); Afterwards, when Button A is pushed: combo.setValue(null); When Button B is pushed: combo.setValue("a"); Now, if I push Button B first, "a" is shown, thats OK. After that if I push Button A, no text is shown on the ComboBox,

问题 I have a problem with the auto-complete behaviour of comboboxes in VB.NET (with the .NET framework 2.0). I am using a combobox to type in numeric values, and its DropDown list to suggest possible numeric values. This list is sorted in ascending order, for example {"10","92", "9000", "9001"}. The combobox properties are set as follow: AutoCompleteMode: SuggestAppend AutoCompleteSource: ListItems DropDownStyle: DropDown Sorted: False The DropDown list is simply filled like this: myCombobox
