I am new to JavaFX so please don't hesitate to explain basic concepts. I am able to create a simple GUI and I have a TabPane with two tabs in my program. My question is how do I create a class that can be used as a node?
For example, tab.setContent(stuff) would add stuff to a tab, tab assuming of course that stuff is a Node. So let's say I create a class called Clock and want to add an instance of it to tab, how do I do such a thing?
The clock should be a graphical object. I'm new to graphical programming so references to Swing etc. won't be particularly helpful.
In your case, create a class "Clock" and extend it with a layout you wish it to contain. For example:
public class Clock extends BorderPane{}
Then, you can set properties or other Nodes to it by using a constructor.
public class Clock extends BorderPane{
TextArea ta = new TextArea("This is TOP");
this.setTop(ta);
Button b1 = new Button("This is button 1");
Button b2 = new Button("This is button 2");
HBox box = new HBox();
box.getChildren().addAll(b1,b2);
this.setCenter(box);
}
Then, you would call it from your main program as such:
@Override
public void start(Stage primaryStage){
primaryStage.setScene(new Scene(new Clock()));
primaryStage.show();
}
In your case, you would set the Scene when the tab is pressed. That can be done using the Tab class and adding an actionListener to it.
tab.setContent(new Clock());
Hope this helped.
Please add a method in clock, then also make a constructor that calls this method. put all
TextArea ta = new TextArea("This is TOP");
this.setTop(ta);
Button b1 = new Button("This is button 1");
Button b2 = new Button("This is button 2");
HBox box = new HBox();
box.getChildren().addAll(b1,b2);
this.setCenter(box);
inside that methode.
