class WeakReference< LookAndFeel >
 

Detailed Description

LookAndFeel objects define the appearance of all the JUCE widgets, and subclasses can be used to apply different 'skins' to the application.

This class is an abstract base-class - for actual look-and-feels that you can instantiate, see LookAndFeel_V1, LookAndFeel_V2 and LookAndFeel_V3.

LookAndFeel_V1, LookAndFeel_V2, LookAndFeel_V3

Constructor & Destructor Documentation

LookAndFeel::LookAndFeel ( )

Creates the default JUCE look and feel.

LookAndFeel::~LookAndFeel ( )
virtual

Destructor.

Member Function Documentation

virtual DropShadower* LookAndFeel::createDropShadowerForComponent ( Component )
pure virtual

Implemented in LookAndFeel_V2.

LowLevelGraphicsContext * LookAndFeel::createGraphicsContext ( const Image imageToRenderOn,
const Point< int > &  origin,
const RectangleList< int > &  initialClip 
)
virtual

Creates a new graphics context object.

virtual void LookAndFeel::drawSpinningWaitAnimation ( Graphics ,
const Colour colour,
int  x,
int  y,
int  w,
int  h 
)
pure virtual

Draws a small image that spins to indicate that something's happening. This method should use the current time to animate itself, so just keep repainting it every so often.

Implemented in LookAndFeel_V2.

Colour LookAndFeel::findColour ( int  colourId) const
noexcept

Looks for a colour that has been registered with the given colour ID number.

If a colour has been set for this ID number using setColour(), then it is returned. If none has been set, it will just return Colours::black.

The colour IDs for various purposes are stored as enums in the components that they are relevent to - for an example, see Slider::ColourIds, Label::ColourIds, TextEditor::ColourIds, TreeView::ColourIds, etc.

If you're looking up a colour for use in drawing a component, it's usually best not to call this directly, but to use the Component::findColour() method instead. That will first check whether a suitable colour has been registered directly with the component, and will fall-back on calling the component's LookAndFeel's findColour() method if none is found.

See also
setColour, Component::findColour, Component::setColour
virtual Path LookAndFeel::getCrossShape ( float  height)
pure virtual

Returns a cross shape for use in yes/no boxes, etc.

Implemented in LookAndFeel_V2, and LookAndFeel_V3.

LookAndFeel & LookAndFeel::getDefaultLookAndFeel ( )
staticnoexcept

Returns the current default look-and-feel for a component to use when it hasn't got one explicitly set.

See also
setDefaultLookAndFeel
MouseCursor LookAndFeel::getMouseCursorFor ( Component component)
virtual

Override this to get the chance to swap a component's mouse cursor for a customised one.

virtual Path LookAndFeel::getTickShape ( float  height)
pure virtual

Returns a tick shape for use in yes/no boxes, etc.

Implemented in LookAndFeel_V2, and LookAndFeel_V3.

Typeface::Ptr LookAndFeel::getTypefaceForFont ( const Font font)
virtual

Returns the typeface that should be used for a given font. The default implementation just does what you'd expect it to, but you can override this if you want to intercept fonts and use your own custom typeface object.

bool LookAndFeel::isColourSpecified ( int  colourId) const
noexcept

Returns true if the specified colour ID has been explicitly set using the setColour() method.

bool LookAndFeel::isUsingNativeAlertWindows ( )
void LookAndFeel::playAlertSound ( )
virtual

Plays the system's default 'beep' noise, to alert the user about something very important.

void LookAndFeel::setColour ( int  colourId,
Colour  colour 
)
noexcept

Registers a colour to be used for a particular purpose. For more details, see the comments for findColour().

See also
findColour, Component::findColour, Component::setColour
void LookAndFeel::setDefaultLookAndFeel ( LookAndFeel newDefaultLookAndFeel)
staticnoexcept

Changes the default look-and-feel.

Parameters
newDefaultLookAndFeelthe new look-and-feel object to use - if this is set to null, it will revert to using the default one. The object passed-in must be deleted by the caller when it's no longer needed.
See also
getDefaultLookAndFeel
void LookAndFeel::setDefaultSansSerifTypefaceName ( const String newName)

Allows you to change the default sans-serif font.

If you need to supply your own Typeface object for any of the default fonts, rather than just supplying the name (e.g. if you want to use an embedded font), then you should instead override getTypefaceForFont() to create and return the typeface.

void LookAndFeel::setUsingNativeAlertWindows ( bool  shouldUseNativeAlerts)
