建構子詳細資訊

BasicInternalFrameTitlePane.SystemMenuBar

public BasicInternalFrameTitlePane.SystemMenuBar()

方法詳細資訊

isFocusTraversable

public boolean isFocusTraversable()

從類別 Component 複製的描述

返回此 Component 是否可以成為焦點所有者。

覆寫：

類別 Component 中的 isFocusTraversable

返回：

如果此 Component 是可以獲得焦點的，則返回 true；否則返回 false

另請參見：

Component.setFocusable(boolean)

requestFocus

public void requestFocus()

從類別 JComponent 複製的描述

請求此 Component 獲取輸入焦點。有關此方法的完整描述，請參閱 Component.requestFocus()。

注意，不推薦使用此方法，因為其行為與平臺有關。建議使用 requestFocusInWindow()。若要瞭解有關焦點的更多資訊，請參閱 The Java Tutorial 中的 How to Use the Focus Subsystem 一節。

覆寫：

類別 JComponent 中的 requestFocus

另請參見：

Component.requestFocusInWindow(), Component.requestFocusInWindow(boolean)

paint

public void paint(Graphics g)

從類別 JComponent 複製的描述

由 Swing 調用，以繪製元件。應用程序不應直接調用 paint，而是應該使用 repaint 方法來安排重繪元件。

此方法實際上將繪製工作委託給三個受保護的方法：paintComponent、paintBorder 和 paintChildren。按列出的順序調用這些方法，以確保子元件出現在元件本身的頂部。一般來說，不應在分派給邊框的 insets 區域繪製元件及其子元件。子類別可以始終覆寫此方法。只想特殊化 UI（外觀）委託的 paint 方法的子類別只需覆寫 paintComponent。

覆寫：

類別 JComponent 中的 paint

參數：

g - 在其中進行繪製的 Graphics 上下文

另請參見：

JComponent.paintComponent(java.awt.Graphics), JComponent.paintBorder(java.awt.Graphics), JComponent.paintChildren(java.awt.Graphics), JComponent.getComponentGraphics(java.awt.Graphics), JComponent.repaint(long, int, int, int, int)

isOpaque

public boolean isOpaque()

從類別 JComponent 複製的描述

如果此元件是完全不透明的，則返回 true。

不透明元件將每個像素繪製在其矩形邊界內。透明的元件則僅繪製部分像素或者不繪製任何像素，允許其底層像素“透視出來”。因此，沒有完全繪製其像素的元件則提供了一定程度的透明度。

保證總是完全繪製其內容的子類別應該覆寫此方法並返回 true。

覆寫：

類別 JComponent 中的 isOpaque

返回：

如果此元件是完全不透明的，則返回 true

另請參見：

JComponent.setOpaque(boolean)
