QLineEdit{text-align:center;}

QLineEdit 设置text-align:center; 不起作用。

This property is currently supported only by QPushButton and QProgressBar.

解决办法

QLineEdit{qproperty-alignment:AlignHCenter;}

edit->setAlignment( Qt::AlignHCenter);

任何可被识别的Q_PROPERTY都可以使用qproperty-语法设置。

Q_PROPERTY定义的属性通过QSS按照qproperty-语法的方式设置。

源代码中可以查看有哪些Q_PROPERTY属性

class Q_WIDGETS_EXPORT QLineEdit : public QWidget { Q_OBJECT Q_PROPERTY(QString inputMask READ inputMask WRITE setInputMask) Q_PROPERTY(QString text READ text WRITE setText NOTIFY textChanged USER true) Q_PROPERTY(int maxLength READ maxLength WRITE setMaxLength) Q_PROPERTY(bool frame READ hasFrame WRITE setFrame) Q_PROPERTY(EchoMode echoMode READ echoMode WRITE setEchoMode) Q_PROPERTY(QString displayText READ displayText) Q_PROPERTY(int cursorPosition READ cursorPosition WRITE setCursorPosition) Q_PROPERTY(Qt::Alignment alignment READ alignment WRITE setAlignment) Q_PROPERTY(bool modified READ isModified WRITE setModified DESIGNABLE false) Q_PROPERTY(bool hasSelectedText READ hasSelectedText) Q_PROPERTY(QString selectedText READ selectedText) Q_PROPERTY(bool dragEnabled READ dragEnabled WRITE setDragEnabled) Q_PROPERTY(bool readOnly READ isReadOnly WRITE setReadOnly) Q_PROPERTY(bool undoAvailable READ isUndoAvailable) Q_PROPERTY(bool redoAvailable READ isRedoAvailable) Q_PROPERTY(bool acceptableInput READ hasAcceptableInput) Q_PROPERTY(QString placeholderText READ placeholderText WRITE setPlaceholderText) Q_PROPERTY(Qt::CursorMoveStyle cursorMoveStyle READ cursorMoveStyle WRITE setCursorMoveStyle) Q_PROPERTY(bool clearButtonEnabled READ isClearButtonEnabled WRITE setClearButtonEnabled) public: ... }
