问题 There is really low quality when loading large bundled images, even when using resizeMethod="resize" . This happens only on Android, not on any iOS simulator/device . Have tested it on Android 8.1 emulator and LG G6 with Android 8.0. Please see the screenshots bellow. At the left screenshot we see the exact same code running with RN 0.56.0 and at the right screenshot we see RN 0.57.5 . The code is just a simple image <Image source={require('./assets/ELHall1.png')} resizeMethod="resize" /> and

问题 My whole idea is a little more complex, but just to break things down so they're simple and to the point here...I have a button on a widget that i need to open the "places" activity in the official facebook app. Here's the code i'm using: Intent PlacesIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER).setComponent(new ComponentName("com.facebook.katana", "com.facebook.katana.activity.places.PlacesNearbyActivity")); PendingIntent pendingIntent = PendingIntent

问题 Tutorials that I found about how to create delphi components were nice, but they only used one of existing components as object to inherit actions from. Something like this unit CountBtn; interface uses Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls, ExtCtrls; type TCountBtn = class(TButton) private FCount: integer; protected procedure Click;override; public procedure ShowCount; published property Count:integer read FCount write FCount; constructor Create

问题 I was able to successfully create a button that on click loads another instance of my component into the DOM, but it loads it outside the component I want it to be inside which results with the CSS being off. When I add "editorComponents" to my page it currently looks like this: But I want it to look like this: You can see from the inspection that in the second example all of the tags are manually moved to where I want them to be. Right now my code is as follows: home.component.html <div

问题 Trying to use Leaflet in an Angular 6 component. Depending on how the css file is linked, the map shows ok or is messed up, there are missing tiles not in the right order, which means the css is not taken into account. I managed to make it work with 2 solutions linking the css to the application level (global), but never only to the component. Here's what I tried (in addition to reading several posts about css/leaflet/Angular): Worked - global level: // styles.css @import url("assets/lib

问题 What is the best way to determine if a component in Flex/Flash is showing on the user's screen? I'm looking for an analog to Java's Component.isShowing() method. The show and hide events fire for visibility, and this seems to work for the first descendant of a ViewStack component, but not further down the display tree. 回答1: UIComponent.visible is not necessarily valid for children of an object where visible=false. From the docs: "In either case the children of the object will not emit a show

问题 I was wondering how to pass an object to a child component using props and retrieving. I understand how to do it as attributes but how to pass an object and retrieve the object from the child component? When I use this.props from the child component I get undefined or an error message. Parent component <template> <div> <child-component :v-bind="props"></child-component> </div> </template> <script> import ChildComponent from "ChildComponent.vue"; export default { name: 'ParentComponent',

问题 I'm looking for a syntax-highlighting Textbox component, preferably free, with source, and capable of being used in Winforms, ASP.NET and WPF alike. Also, it should support not just display, but also editing contents. I've discovered the excellent, FREE ActiPro SyntaxHighlighter for ASP.NET but that's unfortunately ONLY for ASP.NET and it only displays text in syntax highlighted manner, it has no editing capabilities..... I also know of the ICSharp Text Editor component that's part of
