keyboard

问题 Although I've searched, I'm confused about how best to approach this. I have a tableView where the bottom cell is an input to the list, in the same way apple reminders work. When there are too many items on the list, the keyboard covers the list and I can't see what I'm typing. My thought it I need to change the physical size of the table view and ensure it is scrolled to the bottom when the keyboard shows. Some have said keyboard observers but the majority of code I've found for this is out

问题 In my flutter , I create a TextFormField, but it's keyboard color is black in iOS, I want to know how to change it to white. flutter language version: >=2.2.2 <3.0.0 this is my code about the TextFormField: TextFormField( style: TextStyle( fontSize: 14, color: Colors.black), autofocus: false, initialValue: 'initial value', maxLines: 1, // onSaved: (String value) => _person = value, // obscureText: _isObscure, validator: (String value) { if (value.isEmpty) { return 'nononono'; } return null; }

问题 I am using Quartz Event Services to send key commands to applications, but it appears that it was designed to only sent to the front-most window for each application. In Windows, you can send a key event to a specific window using the SendKeys API. I know that you can target specific windows using AppleScripts and send key commands without bringing that window to the foreground for that application, but wondering if there is a way to do this programmatically in C/Objective-C. Seems like the

问题 After a really deep drill down the web, this is my code which unfortunately doesnt send the keys as upper case :/ MapVirtualKey Implementation: const uint MAPVK_VK_TO_VSC = 0x00; const uint MAPVK_VSC_TO_VK = 0x01; const uint MAPVK_VK_TO_CHAR = 0x02; const uint MAPVK_VSC_TO_VK_EX = 0x03; const uint MAPVK_VK_TO_VSC_EX = 0x04; [DllImport("user32.dll")] public static extern int MapVirtualKey(uint uCode, uint uMapType); SendInput Implementation: struct INPUT { public UInt32 Type; public

问题 What is the best way to listen for keyboard input in a Java Applet? I have an applet which opens a JFrame and I am using a KeyListener to listen for keyboard input. This works fine in my development environment (eclipse), but when I run the applet through a browser (I have tried Firefox and IE) it does not respond to keyboard events. However, if I run the applet and then minimize and maximize the frame, it works. I have tried setting focus to the JFrame in many different ways and also
