问题 When moving between panels I get the following error [WARN][Ext.Component#constructor] Registering a component with a id (`logOutButton`) which has already been used. Please ensure the existing component has been destroyed (`Ext.Component#destroy()`. I can go back to the previous screen but the cannot go forward again without getting the above error. To combat this I have tried using the code below, but it does not work. Can anyone help me out? var loginView = Ext.getCmp('login'); if(

问题 We are building a Windows application in .NET and one of its requirements is touch screen monitor. Other than that, it's a normal windows form based application. But except for making UI items little bigger for touch, I can't find anything I as a developer need to do for the requirement since touch screen is basically mouse operations. Am I missing something? 回答1: No, you are not missing anything. Do get the actual hardware hooked up so you can test it, "little bigger" is invariably

问题 I'm working on a JavaFX project and would like to switch from Oracle JDK 1.8 to OpenJDK 11. So far the transition has been pretty seamless, but there is still one main problem related to touch/mouse input that's causing some trouble. The JavaFX UI is supposed to run on a touch-enabled device, which used to work straight out of the box with Oracle JDK 1.8. When I touch the screen, the following sequence of mouse events is fired as expected: MOUSE_PRESSED MOUSE_RELEASED MOUSE_CLICKED After

问题 I have looked around google and stack overflow to find a solution to this but I can't seem to understand why I can't get it to work, I follow everything I see. my problem here is that whenever I touch on a tab it does not change to the tab I have chosen. looking at the moment I am following directions from [This Stackoverflow post][1] Please note that the tabs work when swiping perfectly Here is the XML for the tabview. <?xml version="1.0" encoding="utf-8"?> <android.support.design.widget

问题 How precise is the timestamp property of the UITouch class in iOS? Milliseconds? Tens of milliseconds? I'm comparing an iPad's internal measurements with a custom touch detection circuit taped on the screen, and there is quite a bit of variability between the two (standard deviation ~ 15ms). I've seen it suggested that the timestamp is discretized according to the frame refresh interval, but the distribution I'm getting looks continuous. 回答1: Prior to the iPad Air 2, the touch detection

问题 I'm working on an application that needs to distinguish between physical touchscreen (hardware) touches and software simulated touches invoked by other application. Is there any way to do this without root access? More info: I will be using this to detect if someone is using auto-clicker (auto-tapper?) software on their device to imitate activity in my application. Bump: Still researching for an answer, I can't find any clear explanation online. Can anyone help? 回答1: No. Apps like BotMaker

问题 I've made a tooltip and I want it to close on a touch event outside the tooltip. However I don't want to make an opaque view because I still want the touch to work on whatever was pressed. I tried wrapping my app in a TouchableWithoutFeedback : <TouchableWithoutFeedback onPress={(e) => this.onAppTouch(e)}> This works if the element pressed isn't a Touchable , but otherwise the event seems to get swallowed and not bubble up to that top level onPress . Is there a way to get this to work or else

问题 I'm in the process of writing an 'touch-able' WPF Application for Windows 10. Imagine a window containing the following grid: <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto"></RowDefinition> <RowDefinition Height="*"></RowDefinition> <RowDefinition Height="Auto"></RowDefinition> </Grid.RowDefinitions> <TextBox Text="dsdsd"></TextBox> <TextBox Text="unten" Grid.Row="2" InputScope="Number"></TextBox> </Grid> If my application is compiled using at least .NET 4.6.2 and its window is

问题 I'm trying to get unity to recognize that I am swiping left to right, I have solved that but my issue is that it doesn't understand this till I lift my finger off the screen. My question is how would i make it so that it knows i went right and then left and then right again all without ever taking my finger of the screen Here is the code I have so far using UnityEngine; using System.Collections; public class Gestures : MonoBehaviour { private Vector2 fingerStart; private Vector2 fingerEnd;
