问题 How do I change WebView's default cursor? Every change I make is ignored, the icon always reverts back to the default pointer. Example: import javafx.application.Application; import javafx.scene.Cursor; import javafx.scene.Scene; import javafx.scene.layout.VBox; import javafx.scene.web.WebView; import javafx.stage.Stage; public class Main extends Application { public static void main(String[] args) { launch(args); } public void start(Stage primaryStage) { primaryStage.setTitle("JavaFX WebView

问题 I have lines in a file that look like this: FA General,1234567^^^^^FA Student Letter- General^<<undefined>>^\\path\to\file.RTF I'm trying to use sed to replace the caret characters with commas. If I use: sed 's/\^/,/' file.txt Nothing changes. I've also tried sed 's/\\^/,/' file.txt sed 's/^^/,/' file.txt What am I missing here? 回答1: Do you want to replace all carets? I am sure if you look closely at your result you'll see that the first caret is replaced. So try this: sed -e 's/\^/,/g' file

问题 I have a question concerning the construction of confusion matrix from the below link: Ranger Predicted Class Probability of each row in a data frame If I have the following code for example (as explained by the answer in the link): library(ranger) library(caret) idx = sample(nrow(iris),100) data = iris data$Species = factor(ifelse(data$Species=="versicolor",1,0)) Train_Set = data[idx,] Test_Set = data[-idx,] mdl <- ranger(Species ~ ., ,data=Train_Set,importance="impurity", save.memory = TRUE

问题 In C, I recalled that I can move the invisible caret around the command line interface screen with respect to the line and character position, meaning I can make the program print any text anywhere on the screen. Do we have such command in Java? For instance, here is a pseudocode in C: int main(){ printf("launching program\n"); moveTo(4,3); //move to line 4 at character index 3 on the screen. printf("AAA"); moveTo(3,0); //move to line 3 at character index 0 on the screen. printf("BBB");

问题 I want a non-editable TextField (or a subclass) that doesn't even have the caret displayed. Alternatively, I want a multiline LabelField. Is any of these possible? 回答1: TextField without focus cursor TextField readOnly = new TextField(NON_FOCUSABLE); readOnly.setText("Read only, no carret"); add(readOnly); TextField drawFocus override If text is too large to fit the screen, you can override drawFocus method in TextField, so scrolling will be available: TextField readOnly = new TextField

问题 i'm working on a project (Swift4,Xcode 9.2) which has a feature to get text input and the blinking bar/line should be of big size (it should be Square instead of bar/line) , so i placed a UITextField for Text but i don't understand how to change the size of that blinking line/bar. So, is it possible to change the size of line/bar? and if Yes then how to do it? i know how to change the color of that line/bar but this is something different. 回答1: You can change the size by overriding the frame
