Details:
Steps to reproduce:
1. Compile and run the attached testcase.
Expected results:
1. A window shows up. It has three areas that are separated by two horizontal
lines. First two areas have the height of three lines while the third can only
show two lines of the textarea.
Actual results:
1. A window shows up. It has three areas but the horizontal lines that are
supposed to separate the areas oscillate constantly up and down.
Testcase:
import javax.swing.*;
import java.awt.*;
public class jsplitpane extends JFrame {
public static void main(String[] args) {
(new jsplitpane()).show();
}
public jsplitpane() {
JSplitPane pane1 = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
JSplitPane pane2 = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
pane1.setTopComponent(createTestPanel());
pane1.setBottomComponent(pane2);
pane2.setTopComponent(createTestPanel());
pane2.setBottomComponent(createTestPanel());
this.setContentPane(pane1);
this.setSize(new Dimension(700, 200));
}
JPanel createTestPanel() {
JPanel panel = new JPanel();
JTextArea area = new JTextArea(5,5);
area.setText("line1\nline2\nline3");
panel.add(area);
return panel;
}
}
Note that the text is also bit misaligned but I'll submit another bug report
for that.
