Detailed Description

A widget that organizes contents in tab panes.

This widget has an API that is similar to the WTabWidget.

Unlike WTabWidget, each tab is actually represented by a Panel, and methods are provided to add a panel directly (see addTab(Panel *)). The panel titles are then used as the tab labels.

The widget inherits from Panel, and uses a WDefaultLayout to contain the tab panels. Adding panels to the layout is equivalent to adding tabs to the tab widget.

Example of a TabWidget

Member Function Documentation

void Wt::Ext::TabWidget::addTab	(	WWidget *	child,
		const WString &	label
	)

Add a new tab, with child as content, and the given label.

This is implemented by creating a panel for the widget, and setting the panel title to be the label.

See also: addTab(Panel *), removeTab(int), widget(int)

void Wt::Ext::TabWidget::addTab ( Panel * panel )

Add a new tab panel.

The panel title is used as the tab label.

See also: addTab(WWidget *, const WString&)

Signal<int>& Wt::Ext::TabWidget::currentChanged ( )

Signal emitted when the user activates a tab.

The index of the newly activated tab is passed as an argument.

int Wt::Ext::TabWidget::currentIndex ( ) const

Return the index of the activated tab.

See also: setCurrentIndex(int)

WWidget * Wt::Ext::TabWidget::currentWidget ( ) const

Return the widget of the activated tab.

See also: setCurrentWidget(WWidget *), currentIndex()

int Wt::Ext::TabWidget::indexOf ( WWidget * widget ) const

Return the index of the given widget/panel.

If the widget was not added to this tab widget, then -1 is returned.

Panel * Wt::Ext::TabWidget::panel ( int index ) const

Return t the panel at the given tab index.

See also: widget(int)

void Wt::Ext::TabWidget::refresh ( )

virtual

Refresh the widget.

The refresh method is invoked when the locale is changed using WApplication::setLocale() or when the user hit the refresh button.

The widget must actualize its contents in response.

Note: This does *not* rerender the widget! Calling refresh() usually does not have any effect (unless you've reimplemented refresh() to attach to it an effect).

Reimplemented from Wt::Ext::Panel.

void Wt::Ext::TabWidget::removeTab ( int index )

Remove a tab.

See also: addTab(Panel *), addTab(WWidget *, const WString&); indexOf(WWidget *)

void Wt::Ext::TabWidget::setCurrentIndex ( int index )

Activate the tab at index.

See also: setCurrentWidget(WWidget *), currentIndex(); currentChanged() signal

void Wt::Ext::TabWidget::setCurrentWidget ( WWidget * widget )

Activate the tab showing the given widget

This is equivalent to setCurrentIndex(indexOf(widget))

See also: currentWidget(), setCurrentIndex(int)

void Wt::Ext::TabWidget::setTabEnabled	(	int	index,
		bool	enable
	)

Enable or disable a tab.

Enables or disables the tab at index. A disabled tab cannot be activated.

void Wt::Ext::TabWidget::setTabHidden	(	int	index,
		bool	hidden
	)

Hide or show a tab.

Hides are shows the tab at index.

void Wt::Ext::TabWidget::setTabText	(	int	index,
		const WString &	label
	)

Change the label for a tab.

This is equivalent to panel(index)->setTitle(label);

See also: tabText(int)

void Wt::Ext::TabWidget::setTabToolTip	(	int	index,
		const WString &	tip
	)

Set the tooltip for a tab.

The tooltip is shown when the user hovers over the label.

This seems currently broken in extjs 2.0.

const WString & Wt::Ext::TabWidget::tabText ( int index ) const

Return the label for a tab.

See also: setTabText(int, const WString&)

WWidget * Wt::Ext::TabWidget::widget ( int index ) const

Return the content widget at the given tab index.

See also: panel(int)
