如何瀏覽已禁用的QLineEdit小部件？

Question

如果我有5個QLineEdit小部件排隊。讓用戶在他們之間導航的最佳方式是什麼（跳過任何被禁用的）？

 
QLineEdit a (enabled) -> QLineEdit b (enabled) -> QLineEdit c (disabled) -> QLineEdit d (disabled) -> QLineEdit e (enabled) 

Answer 1

聽起來像要使用QKeyEvents。

一個簡單的實現將是這樣的：

class MyClass : public QWidget 
{ 
    //whatever you want 
    protected: 
    //here, override the virtual function keyPressEvent (from QWidget) 
    void QWidget::keyPressEvent(QKeyEvent* ev) 
    { 
    //check for the key(s) you care about and handle the event if needed 
    //by iterating through lineEditList, asking each QLineEdit* if 
    //the 'enabled' property is true. When you find the appropriate one, 
    //set the cursor to that widget. 
    } 
    QList<QLineEdit*> lineEditList; 
    int currentLineEditIndex; 
}; 

實施的細節是你的，當然。
