详细描述

The Q3CheckTableItem class provides checkboxes in Q3Tables.

A Q3CheckTableItem is a table item which looks and behaves like a checkbox. The advantage of using Q3CheckTableItems rather than real checkboxes is that a Q3CheckTableItem uses far less resources than a real checkbox would in a Q3Table . When the cell has the focus it displays a real checkbox which the user can interact with. When the cell does not have the focus the cell looks like a checkbox. Pixmaps may not be used in Q3CheckTableItems.

Q3CheckTableItem items have the edit type WhenCurrent (见 EditType ).

To change the checkbox's label use setText (). The checkbox can be checked and unchecked with setChecked () and its state retrieved using isChecked ().

To populate a table cell with a Q3CheckTableItem 使用 Q3Table::setItem ().

Q3CheckTableItems can be distinguished from Q3TableItem s and Q3ComboTableItem s using their Run Time Type Identification (rtti) value.

成员函数文档编制

Q3CheckTableItem:: Q3CheckTableItem ( Q3Table * table , const QString & txt )

创建 Q3CheckTableItem with an EditType of WhenCurrent 作为子级对于 table . The checkbox is initially unchecked and its label is set to the string txt .

[虚拟] QWidget * Q3CheckTableItem:: createEditor () const

重实现自 Q3TableItem::createEditor ().

bool Q3CheckTableItem:: isChecked () const

Returns true if the checkbox table item is checked; otherwise returns false.

另请参阅 setChecked ().

[虚拟] void Q3CheckTableItem:: paint ( QPainter * p , const QColorGroup & cg , const QRect & cr , bool selected )

重实现自 Q3TableItem::paint ().

[虚拟] int Q3CheckTableItem:: rtti () const

重实现自 Q3TableItem::rtti ().

Returns 2.

Make your derived classes return their own values for rtti()to distinguish between different table item subclasses. You should use values greater than 1000, preferably a large random number, to allow for extensions to this class.

另请参阅 Q3TableItem::rtti ().

[虚拟] void Q3CheckTableItem:: setChecked ( bool b )

若 b is true the checkbox is checked; if b is false the checkbox is unchecked.

另请参阅 isChecked ().

[虚拟] void Q3CheckTableItem:: setContentFromEditor ( QWidget * w )

重实现自 Q3TableItem::setContentFromEditor ().

[虚拟] void Q3CheckTableItem:: setText (const QString & t )

重实现自 Q3TableItem::setText ().

[虚拟] QSize Q3CheckTableItem:: sizeHint () const

重实现自 Q3TableItem::sizeHint ().
