设置文件选择对话框大小及纵向大小不可变--JAVA-SWING-JFileChooser-setMinimumSize

要求：使文件选择对话框不可变小，纵向大小不可变大，横向大小可变大

实现：重写createDialog事件，并指定最小宽高、纵向大小变大时自动重设

private JFileChooser fileChooser = new JFileChooser(){

protected JDialog createDialog(Component parent) throws HeadlessException {

final JDialog dialog = super.createDialog(parent);

int defaultWidth = dialog.getWidth();

final int defaultHeight = dialog.getHeight();

dialog.setMinimumSize(new java.awt.Dimension(defaultWidth, defaultHeight));

dialog.addComponentListener(new ComponentAdapter() {

public void componentResized(ComponentEvent e) {

int currentWidth = dialog.getSize().width;

dialog.setSize(currentWidth, defaultHeight);

}

});

return dialog;

}

};
