TextArea txt = new TextArea();
我该调用哪个方法来设置这个
TextArea
的高度和宽度?TextArea textArea = new TextArea(); //making a TexrArea object
double height = 400; //making a variable called height with a value 400
double width = 300; //making a variable called height with a value 300
//You can use these methods
textArea.setPrefHeight(height); //sets height of the TextArea to 400 pixels
textArea.setPrefWidth(width); //sets width of the TextArea to 300 pixels
setPrefColumnCount() 和 setPrefRowCount() 工作正常。
TextArea textArea = new TextArea();
double prefWidth = 1.0
double prefHeight = 1.0
textArea.setPrefSize(prefWidth, prefHeight);
setPrefColumnCount()
和setPrefRowCount()
应该能够满足您的需求。请参阅此处。 - Draken
