extjs4

Looking at the deploy process for an ExtJS 4 application I performed the following steps (using SDK Tools 2.0.0-beta3): sencha create jsb -a http://localhost:8080/myapp/ -p app.jsb3 sencha build -p app.jsb3 -d . This created for me all-classes.js and app-all.js . The next step was to switch form ext-all.js to ext.js . Doing that my app stop working. Looking at the console, I noticed that Ext tried to load the required classes separately, from a src folder. src/AbstractPlugin.js?_dc=1372193551701 So, I'm assuming that ext.js requires the src folder that have the unminified version of the

What is the proper way to scroll a grid horizontally on load. I want to scroll to a particular grid column on load. I can focus the column I want using this: dataStore.on('load', function() { var cl = dataGrid.columns[43]; cl.focus(); }); but the grid does not scroll when I do this. One possibility is to use scrollByDeltaX . Example: viewready: function(){ var c = this.columns[5]; var p = c.getPosition(); this.scrollByDeltaX(p[0]); } Working sample: http://jsfiddle.net/YRraU/2/ 来源： https://stackoverflow.com/questions/13545674/how-to-scroll-extjs-4-grid-horizontally

I have added default remote filter to grid for column 'hiddenFlag', however it is not active on first loading. When I click column header menu, filter seem to be active however records is now appropriate. I should deactivate and activate it again. how, I can configure it to be active for the first load also? Ext.define('Ext.migration.CommentGrid', { extend: 'Ext.grid.Panel', alias: 'widget.commentgrid', xtype: 'grid', initComponent: function(){ filePath = ""; this.filters = { ftype: 'filters', encode: false, // json encode the filter query local: false, //only filter locally filters: [{ type:

I have a form with various textfields and two buttons - Export to Excel and Export to CSV. The user can provide the values to different fields in the form and click one of the buttons. Expected behaviour is that an Ajax request should be fired carrying the values of fields as parameters and the chosen file (Excel/CSV as per the button click) should get downloaded (I am not submitting the form as there needs to be done some processing at the values before submit). I have been using the following code in success function of Ajax request for the download: result = Ext.decode(response.responseText

I want to change the proxy of a store before (!) it is loaded. The specific problem in this case is that I do not find the right moment, when to load. In detail: I have created a MVC-model by creating a view, a controller, a model, and a store as defined by EXTJS4 architecture. The view is a grid panel. It defines the store within its own define statement: Ext.define('P.view.MyView' ,{ extend: 'Ext.grid.Panel', alias : 'widget.MyView', ... store: 'MyStore', ... } When I load the store with "autoload:true" everything works fine, but of course the proxy is then static as defined in the code.

For some reason I need to know when user has selected value from combobox even if it is already selected. "Select" event works only if user selects unselected item. I don't see any event like "itemclick" in the docs for combobox or picker. Any ideas? ComboBox uses BoundList for representing dropdown list. BoundList fires itemclick event. You can use ComboBox 's listConfig config in order to setup BoundList listeners: Ext.create('Ext.form.ComboBox', { // ... listConfig: { listeners: { itemclick: function(list, record) { alert(record.get('name') + ' clicked'); } } } } Check out the demo . 来源：
