keyboard

问题 I'm using a react-native Modal, which contains a View. The View has some TextInput elements. When the keyboard pops up, the View elements all collapse to fit into the remaining space, but I don't want the View to change at all. This does not happen for IOS. And also, it does not happen in non-modal Views for Android within the same app. I have windowSoftInputMode="adjustPan" set in my android Manifest, but it doesn't seem to be applied on the Modal. return( <ImageBackground source={require('.

问题 Is there a simple means of dismissing the keyboard or any other active control when another control such as a date picker becomes active? Or vice versa. There are some solutions for dismissing the keyboard, but which also disable the use of a picker. Possibly there is an event other than onTapGesture to use. Follows is some sample code that illustrates the problem. struct TestView: View { @State private var firstname = "" @State private var surname = "" @State private var birthdate = Date()

问题 With the help of some of the Cyberintelligensia, I am now able to use combinations of Ctrl+[some displayable key], Ctrl+Shift+[some displayable key], and Ctrl+Shift+Alt+[some displayable key] to add accented chars into a textbox. The question and its answers are here. However, there is still one recalcitrant combination. I used CodeCaster's suggestion to add a call to "Debug.WriteLine(keyData);" to see what in tarnation was being pressed (which keys). This works fine in most cases; for

问题 I tried with this code to detect two keyboard arrows being simultaneously pressed: document.addEventListener('keydown', event => { if (event.keyCode === 38) { console.log('up Arrow') } if (event.keyCode === 39) { console.log('right Arrow') } }) But it doesn't work, however hard I try to press them at exactly the same time. How can I cleanly fix this and detect when both keys are down ? 回答1: There's only one keyCode per event. You have to track the keys going down, and up: // if you keep both

问题 I have to write an on screen keyboard for our company's program, which is mostly used on industry's PCs with touch capability. We can't use the windows default keyboard because we don't need all keys on the keyboard. So I was asked to write a custom one in C#. I already found this blog as reference, but I'm not sure how to start. I created a small prototype GUI and assign for each key a scancode, and translate these scancodes to the related character. And send them to the active control. But
