overriding

问题 I've created my own theme as a separate Maven project, and it is loaded correctly. Now I want to change the size of an component. For example, a <p:orderList>. It has a class called ui-orderlist-list which is defined in primefaces.css with a fixed 200x200 dimension. No matter what I do in my theme.css , it is overwritten by this attribute and there is no way I can make the content part of a <p:orderList> wider. For other components I might want to override just one instance of a component,

问题 I am facing an issue trying to override StrongLoop built in method for PUT request. So in model.js file I am using: Model.on('attached', function(){ Model.updateAttributes = function(data, id, cb){ cb(null,'This is a overridden method'); }; } But when I call the endpoint with a PUT /api/v1/models/1 and payload this function does not get executed but the built in one. I also tried to use other function instead of updateAttributes but without any success like for example: Model.updateAll =

问题 In my MVC app I have a few generic base controllers that handle Create\Edit\Delete actions and work without a single change in code (aside from defining the class) for multiple models. Occasionally I need to alter one of the basic actions for some particular model and I achieve that using override . Now, the question is, do the overridden actions inherit action filters from their base version or do they lose those? For I second I thought that I can check that quickly in my existing code, but

问题 I have an app where I've pushed two items onto the navigation bar. The top item, which ends up as a 'back' button, should have the function to jump all the way back to the start page, which is a list of web news. The other one simply displays a logo. The boss wants a navigation bar look and feel but with a simple function, so the user can click around the news site, but always be able to jump to the news list page with just the one click. Is the only option to create a fixed navbar with two

问题 I'm working with BigDecimal s and I have the requirement that a division by 0 should not result in an ArithmeticException , but in returning 0 instead (weird business math). This is a rather new requirement and we already have quite a bit of code, which uses BigDecimal s in a lot of places. I don't want to go through all these places and implement zero checks. This also would not help me with 3rd party libraries, which might internally use BigDecimal s and will throw an ArithmeticException

问题 What is the correct way to override the cut(), copy(), and paste() methods of the Text control? What triggers the execution of these methods? I have created an example application with a custom class that overrides these methods. Unfortunately, nothing seems to execute these overridden methods, including the act of using Ctrl + X / Ctrl + C / Ctrl + V or selecting cut/copy/paste from the context menu. Custom Text Class: import org.eclipse.swt.widgets.Composite; import org.eclipse.swt.widgets

问题 Imagine a table view controller ExtraRowTableViewController , which always inserts an extra row, after (let's say) the third row. So in this example ... class SomeList:ExtraRowTableViewController override func numberOfSectionsInTableView(tableView: UITableView)->Int { return yourData.count ... say, 50 items } override func tableView (tableView:UITableView, cellForRowAtIndexPath indexPath:NSIndexPath) -> UITableViewCell { return yourData.cell ... for that row number }
