The Frame container is capable of containing one widget and it places a rectangle box around it. You can also have a label attached to the box. The box can have different appearances which is described by type ShadowType. The possible vales for ShadowType are as follows:
Here is a little bit of the createLabels() method from TestGTK to demonstrate the usage of Frame.
Example 6-2. TestGTK.java - Frame
public void createLabels() { Window win = new Window(WindowType.TOPLEVEL); win.setTitle("labels"); win.setBorderWidth(5); VBox vbox1 = new VBox(false, 5); HBox hbox = new HBox(false, 5); win.add(hbox); hbox.packStart(vbox1, false, false, 0); Frame frame = new Frame("Normal Label"); Label label = new Label("This is a Normal Label"); frame.add(label); vbox1.packStart(frame, false, false, 0); frame = new Frame("Multi-Line Label"); label = new Label("This is a Multi-Line Label. \nSecond line\nThird line"); frame.add(label); vbox1.packStart(frame, false, false, 0); frame = new Frame("Left Justiied Label"); label = new Label("This is a Left-Justified\nMulti-line label.\nThird line"); label.setJustification(Justification.LEFT); frame.add(label); vbox1.packStart(frame, false, false, 0);
