dialog

问题 I have a method that checks several conditions, and calls another activity when they are satisfied. When a condition isn't satisfied, it should display an error dialog (which is currently using a DialogFragment to display an alert dialog). The method looks something like this: void checkAndCall() { CustomObject o1 = null; try { o1 = CustomObject.parse(editText1.getText().toString()); } catch (CustomException e) { handleBadCase(e); return; } CustomObject o2 = null; try { o2 = CustomObject

问题 I want to show an AlertDialog when a http get fails. The function showDialog (https://api.flutter.dev/flutter/material/showDialog.html) has the parameter "@required BuildContext context", but I want to call the AlertDialog from my async function getNews(), which hasn't a context value. By analogy with Java, where I use null for dialog without an owner, I tried to put context value to null, but it is not accepted. This is my code: Future<dynamic> getNews() async { dynamic retVal; try { var

问题 How (or is it even possible) to use custom HTML dialogs in Electron? I know that Electron provides certain dialogs ( showMessageDialog , showErrorDialog ) but these do not seem to allow custom HTML. I do not wish to use native HTML dialogs ( dialog ) tag as it does not 'blend in' with the user interface. Any help would be much appreciated. Thanks! 回答1: You can create a BrowserWindow that's modal and, if you like, frameless. See http://electron.atom.io/docs/api/browser-window/. 回答2: Yes. On
