Detailed Description

A component with a TabbedButtonBar along one of its sides.

This makes it easy to create a set of tabbed pages, just add a bunch of tabs with addTab(), and this will take care of showing the pages for you when the user clicks on a different tab.

Member Enumeration Documentation

ColourIds

enum TabbedComponent::ColourIds

A set of colour IDs to use to change the colour of various aspects of the component.

These constants can be used either via the Component::setColour(), or LookAndFeel::setColour() methods.

See also

Component::setColour, Component::findColour, LookAndFeel::setColour, LookAndFeel::findColour

Enumerator
backgroundColourId	The colour to fill the background behind the tabs.
outlineColourId	The colour to use to draw an outline around the content. (See setOutline)

Constructor & Destructor Documentation

TabbedComponent()

TabbedComponent::TabbedComponent ( TabbedButtonBar::Orientation  orientation )

explicit

Creates a TabbedComponent, specifying where the tabs should be placed.

Once created, add some tabs with the addTab() method.

~TabbedComponent()

TabbedComponent::~TabbedComponent ( )

override

Destructor.

Member Function Documentation

setOrientation()

void TabbedComponent::setOrientation

(

TabbedButtonBar::Orientation

orientation

)

Changes the placement of the tabs.

This will rearrange the layout to place the tabs along the appropriate side of this component, and will shift the content component accordingly.

See also

TabbedButtonBar::setOrientation

getOrientation()

TabbedButtonBar::Orientation TabbedComponent::getOrientation ( ) const

noexcept

Returns the current tab placement.

See also

setOrientation, TabbedButtonBar::getOrientation

setTabBarDepth()

void TabbedComponent::setTabBarDepth

(

int

newDepth

)

Specifies how many pixels wide or high the tab-bar should be.

If the tabs are placed along the top or bottom, this specified the height of the bar; if they're along the left or right edges, it'll be the width of the bar.

getTabBarDepth()

int TabbedComponent::getTabBarDepth ( ) const

noexcept

Returns the current thickness of the tab bar.

See also

setTabBarDepth

setOutline()

void TabbedComponent::setOutline

(

int

newThickness

)

Specifies the thickness of an outline that should be drawn around the content component.

If this thickness is > 0, a line will be drawn around the three sides of the content component which don't touch the tab-bar, and the content component will be inset by this amount.

To set the colour of the line, use setColour (outlineColourId, ...).

setIndent()

void TabbedComponent::setIndent

(

int

indentThickness

)

Specifies a gap to leave around the edge of the content component.

Each edge of the content component will be indented by the given number of pixels.

clearTabs()

void TabbedComponent::clearTabs

(

)

Removes all the tabs from the bar.

See also

TabbedButtonBar::clearTabs

addTab()

void TabbedComponent::addTab	(	const String &	tabName,
		Colour	tabBackgroundColour,
		Component *	contentComponent,
		bool	deleteComponentWhenNotNeeded,
		int	insertIndex = -1
