㈡ Java 怎樣獲取標題欄的高度

自己已找到方法（沒辦法，沒人回，只能靠自己。。）：

用java.lang.Container的getInsets()方法可以獲得標題欄的寬度和高度，Insets對象是容器邊界的表示形式，有top,left,right,bottom四個屬性可用。

An Insets object is a representation of the borders of a container. It specifies the space that a container must leave at each of its edges. The space can be a border, a blank space, or a title.

㈢ java如何獲取窗體標題欄的顏色

類 java.awt.SystemColor
SystemColor.activeCaption
SystemColor.inactiveCaption

㈣ 怎樣隱藏窗口標題欄（java）

樓主你好

可以用JFrame(或者Frame)類對象的setUndecorated方法來實現

public void setUndecorated(boolean undecorated)
禁用或啟用此組件的裝飾.

當參數設為true時 就隱藏了窗口標題欄

給lz一個例子:

import javax.swing.*;
public class Test extends JFrame
{
public Test()
{
this.setUndecorated(true);//隱藏標題欄
this.setSize(300,300);
this.setVisible(true);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

public static void main (String[] args) {
new Test();
}
}

希望能幫助你哈

㈤ java讓標題欄顯示信息

你說的是網頁的標題欄嗎？在<title>標簽里寫就可以了：

<html>
<title>這是我的班級</title>

<body>
</body>
</html>

㈥ Java中如何更換窗口標題欄字體（如何通過軟體代碼修改）

復制以下代碼，修改相應地方即可：

privatestaticvoidloadIndyFont()
{
UIManager.put("CheckBox.font",newjava.awt.Font("宋體",0,12));
UIManager.put("Tree.font",newjava.awt.Font("宋體",0,12));
UIManager.put("Viewport.font",newjava.awt.Font("宋體",0,12));
UIManager.put("ProgressBar.font",newjava.awt.Font("宋體",0,12));
UIManager.put("RadioButtonMenuItem.font",newjava.awt.Font("宋體",0,12));
UIManager.put("FormattedTextField.font",newjava.awt.Font("宋體",0,12));
UIManager.put("ToolBar.font",newjava.awt.Font("宋體",0,12));

UIManager.put("Spinner.font",newjava.awt.Font("宋體",0,12));
UIManager.put("Menu.acceleratorFont",newjava.awt.Font("宋體",0,12));
UIManager.put("CheckBoxMenuItem.acceleratorFont",newjava.awt.Font("宋體",0,12));

UIManager.put("PasswordField.font",newjava.awt.Font("宋體",0,12));

UIManager.put("OptionPane.messageFont",newjava.awt.Font("宋體",0,12));
UIManager.put("EditorPane.font",newjava.awt.Font("宋體",0,12));
UIManager.put("Table.font",newjava.awt.Font("宋體",0,12));
UIManager.put("TabbedPane.font",newjava.awt.Font("宋體",0,12));
UIManager.put("RadioButton.font",newjava.awt.Font("宋體",0,12));
UIManager.put("CheckBoxMenuItem.font",newjava.awt.Font("宋體",0,12));
UIManager.put("TextPane.font",newjava.awt.Font("宋體",0,12));
UIManager.put("PopupMenu.font",newjava.awt.Font("宋體",0,12));
UIManager.put("TitledBorder.font",newjava.awt.Font("宋體",0,12));
UIManager.put("ComboBox.font",newjava.awt.Font("宋體",0,12));
