components

问题 I guess simple answer to the question would be a component . Although I agree, I feel weird having to write a component for something so specific. For example, let's say I have a table of users.

问题 How to set custom time to Android AnalogClock placed in app widget? As an alternative I was thinking to override default AnalogClock to set the time through codes.

I'm afraid we are limited on RemoteViews to have our own custom Component. UPDATE: This is error log I have following the solution given by vArDo at first. 回答1: Intro It's

问题 We have a requirement to add the ability to edit PDF documents witin a Delphi application. I.e. given a PDF document, open it and generate a form with edit boxes on it which the user can use to update the PDF document. Can anyone suggest a third part component that would provide this functionality or suggest some way of achieving this. Thanks 回答1: I use QuickPDF. Well documented, lots of examples, good support.

问题 I seem to be seeing examples, where people answer to questions how to get some specific behavior from components by adding CSS code, however nobody seems to explain how to use that CSS code to connect it to Java components... .v-table-body{ overflow: hidden !important; } How do I use for instance this code on my table that I create? Table table = new Table(caption); table.addContainerProperty("Visit ID", Long.class, null); 回答1: You can create you own custom theme. See https://vaadin.com/book/

Here is my service:- import {Injectable} from '@angular/core'; @Injectable() export class TestService { public _test:any; set test(value:any) { this._test = value } get test():any { return this._test; } } I set the service like:-

问题 I have a ColdFusion session variable that's a structure of data. My goal is to execute a jQuery call that does one of two things via Ajax: sends that ColdFusion structure to a ColdFusion component method, updates an element of that structure with a newly created string, and returns that same structure back. or executes a ColdFusion component method that creates a new string, returns that string, and assigns that new string to an element of that same ColdFusion session structure after the Ajax

问题 I was wondering if there is a way (any components/controls) that allow me to draw a simple Microsoft Word style table in my application window. Something like this: Any ideas? 回答1: It depends on how you want to use it. Either use one of the ItemsControl (like DataGrid , ListView etc), do it directly with a Grid panel (as recommended by the other answers) or use a FlowDocument FlowDocument allows you to specify Tables, Rows and Columns. You can also select several cells at once for Copy/Paste

问题 I have a general idea, and there are some obvious cases, but there are also some gray areas for me - when is it best to use to extend from a component and when is it best to create a user control? This pertains to a specific work problem I am trying to solve, but the specifics of that are not important - a general answer to this question is enough for me. 回答1: In WPF and Windows Forms, both, the main difference is that a UserControl is meant to be a collection of controls - a reusable, single
