当文本更改时,将发出textChanged()信号;当文本更改不是通过调用setText()时,将发出textEdited()信号;当光标移动时,将发出cursorPositionChanged()信号;当按下回车键或回车键时,将发出returnPressed()信号。 编辑完成后,无论是因为行编辑失去焦点还是按下回车键,都会发出editing finished()信号。 注意,如果在edit行...

When editing is finished, either because the line edit lost focus or Return/Enter is pressed the editingFinished() signal is emitted. Note that if there is a validator set on the line edit, the returnPressed()/editingFinished() signals will only be emitted if the validator returns QValidator:...

Qt C++ 是一个跨平台的应用程序开发框架,它为开发者提供了创建图形用户界面(GUI)以及实现各种功能所需的丰富类库。Qt C++ 的核心优势在于其跨平台特性,能够在多个操作系统(如 Windows、macOS、Linux、Android 和 iOS)上编写统一的代码,并实现原生应用程序的效果。Qt C++ 的设计理念使得开发者可以用较低的学习成本快...
When the user has finished editing the value in the spin box, the view asks the delegate to store the edited value in the model by calling the setModelData() function. void SpinBoxDelegate::setModelData(QWidget *editor, QAbstractItemModel *model, const QModelIndex &index) const { QSpinBox ...
