Detailed Description

The Stylesheet class represents all style information.

It is organised in types, which corresponds to the Components created, classes that can be referenced by any node, and nodes referenced by id.

Member Function Documentation

◆ setStyle()

void setStyle ( const juce::ValueTree & node )

The Stylesheet node in the XML can contain several Styles to select from.

Use this method to select a style.

References Stylesheet::setColourPalette().

Referenced by MagicGUIBuilder::updateStylesheet().

◆ setMediaSize()

bool setMediaSize	(	int	width,
		int	height )

Set the size of the UI.

This will be used to resolve the properties from the style classes.

Parameters

width	is the width of the UI
height	is the height of the UI

Returns: false, if the properties are likely to have changed (because a conditional class became valid or invalid)

Referenced by MagicGUIBuilder::updateLayout().

◆ updateValidRanges()

void updateValidRanges ( )

Reads the range, in which the properties won't change due to conditional classes.

Referenced by MagicGUIBuilder::updateLayout(), and MagicGUIBuilder::updateStylesheet().

◆ updateStyleClasses()

void updateStyleClasses ( )

Read the style classes and connect variables.

References MagicGUIBuilder::getMagicState(), and MagicGUIState::getPropertyAsValue().

Referenced by MagicGUIBuilder::updateStylesheet().

◆ setColourPalette()

void setColourPalette ( )

Updates the colourPalette.

References MagicGUIBuilder::getUndoManager().

Referenced by Stylesheet::setStyle(), and Stylesheet::Stylesheet().

◆ addPaletteEntry()

void addPaletteEntry	(	const juce::String &	name,
		juce::Colour	colour,
		bool	keepIfExists )

References MagicGUIBuilder::getUndoManager().

Referenced by PropertiesEditor::PropertiesEditor().

◆ getCurrentPalette()

juce::ValueTree getCurrentPalette ( )

◆ getPaletteEntryNames()

juce::StringArray getPaletteEntryNames ( ) const

Returns all variables for selection in colour values.

Referenced by StyleColourPropertyComponent::StyleColourPropertyComponent().

◆ getStyleProperty()

juce::var getStyleProperty	(	const juce::Identifier &	name,
		const juce::ValueTree &	node,
		bool	inherit = true,
		juce::ValueTree *	definedHere = nullptr ) const

This method traverses the dom and checks each style, if that property was defined.

Parameters

name	the name of the property.
node	is the node in the DOM. This is used for inheritance by traversing upwards.
inherit	if this is true, it will impact child nodes as well
definedHere	this is a hint for the editor where the property was actually set

Referenced by Stylesheet::getBackgroundImage(), Stylesheet::getLookAndFeel(), MagicGUIBuilder::getStyleProperty(), Stylesheet::getStyleProperty(), and StylePropertyComponent::lookupValue().

◆ getLookAndFeel()

juce::LookAndFeel * getLookAndFeel ( const juce::ValueTree & node ) const

Return the LookAndFeel for the node.

Make sure never to remove a LookAndFeel, especially as long as the ComponentTree is still referencing any of them.

Parameters

node	is the node in the GUI DOM

References Stylesheet::getStyleProperty().

Referenced by StyleColourPropertyComponent::StyleColourPropertyComponent().

◆ getBackgroundImage()

juce::Image getBackgroundImage ( const juce::ValueTree & node ) const

Finds a background image for the given node.

Note that this will only return anything useful, if you have added any actual images into the BinaryData and have enabled the FOLEYS_ENABLE_BINARY_DATA setting in the module page.

Parameters

node	is the node in the GUI DOM

References Stylesheet::getStyleProperty().

◆ parseColour()

juce::Colour parseColour ( const juce::String & name )

static

This is a slightly more intelligent colour lookup than the JUCE one, as it allows to use colour names, as well as 6 digit colour tuples (JUCE will use red as alpha in that case)

Parameters

name	a string representing the colour, can be an actual name or a RGB tuple or ARGB tuple.

Referenced by Stylesheet::getColour(), and RootItem::updateColours().

◆ getColour()

juce::Colour getColour ( const juce::String & name ) const

Lookup a colour.

This will go through the colourPalette to catch variables like $text.

References Stylesheet::parseColour().

Referenced by GradientBackground::setup(), StyleColourPropertyComponent::StyleColourPropertyComponent(), and GuiItem::updateColours().

◆ getCurrentStyle()

juce::ValueTree getCurrentStyle ( ) const

Referenced by ToolBox::stateWasReloaded().

◆ addNewStyleClass()

juce::ValueTree addNewStyleClass	(	const juce::String &	name,
		juce::UndoManager *	undo )

Add a new style class node, so elements of your GUI can inherit that class.

Parameters

name	is the name of the new class. Make sure you only use XML conform identifiers, i.e. characters, numbers but not starting with a number, dash and underscore only.
undo	the UndoManager to track the action

Referenced by PropertiesEditor::createNewClass().

◆ deleteStyleClass()

void deleteStyleClass	(	const juce::String &	name,
		juce::UndoManager *	undo )

Delete a style class.

This will not delete references to the class.

Parameters

name	the name of the class to be deleted.
undo	the UndoManager to track the action

Referenced by PropertiesEditor::deleteClass().

◆ registerLookAndFeel()

void registerLookAndFeel	(	juce::String	name,
		std::unique_ptr< juce::LookAndFeel >	lookAndFeel )

With that method you can register your custom LookAndFeel class and apply it to different components.

Parameters

name	the name the LookAndFeel can be referenced in the GUI editor
lookAndFeel	is an actual LookAndFeel instance, that is owned by the Stylesheet
