问题 Just wondering if there is any command in OpenCV to create an input "Text box" or"Edit text box" for a GUI in C++? Like name box (to enter a name) PS: I'm using Linux (Ubuntu) 回答1: As Miki says, there is no such facility in OpenCV itself, but there is nothing to stop you using Zenity or any of the alternatives, which work like this at the command line: zenity --title "Gimme some text!" --entry --text "Enter your text here" If it does what you want, you can integrate it into your C++ program

问题 I wrote a simple layout which has an EditText , but it's showing the following warning message: “No label views point to this text field” While searching I found this and it solved that warning message, but did not get difference between both attributes android:id and android:labelFor . Any clarification? 回答1: android:id Supply an identifier name for this view, to later retrieve it with View.findViewById() or Activity.findViewById() . This must be a resource reference; typically you set this

问题 I want to make an editbox in a MATLAB GUI which will only allow numbers or only allow letters to be typed into it. Is this possible? 回答1: There is no such feature, at least not a documented one. You could assign a callback that will check the input, but that will happen after the user entered illegal character. Though I don't know how exactly to do it, my guess is that you can use Java GUI. Another interesting option is to add an ActiveX that will do the job. Edit: I have found an ActiveX
