Detailed Description

An extended version of RibbonWidget, with more capabilities.

A dynamic ribbon builds upon RibbonWidget, adding dynamic contents creation and sizing, scrolling, multiple-row layouts.

Note: items you add to a list are kept after the the ribbon was in is removed (i.e. you don't need to add items everytime the screen is shown, only upon loading)

Constructor & Destructor Documentation

◆ DynamicRibbonWidget()

DynamicRibbonWidget::DynamicRibbonWidget	(	const bool	combo,
		const bool	multi_row
	)

Parameters

combo	Whether this is a "combo" ribbon, i.e. whether there is always one selected item. If set to false, will behave more like a toolbar.
multi_row	Whether this ribbon can have more than one row

Member Function Documentation

◆ addAnimatedItem()

void DynamicRibbonWidget::addAnimatedItem	(	const irr::core::stringw &	user_name,
		const std::string &	code_name,
		const std::vector< std::string > &	image_files,
		const float	time_per_frame,
		const unsigned int	badge = `0`,
		IconButtonWidget::IconPathType	image_path_type = `IconButtonWidget::ICON_PATH_TYPE_RELATIVE`
	)

Dynamically add an animated item to the ribbon's list of items (will not be visible until you call 'updateItemDisplay' or 'add').

Animated means it has many images that will be shown in a slideshown fashion.

Parameters

user_name	The name that will shown to the user (may be translated)
code_name	The non-translated internal name used to uniquely identify this item.
image_files	A path to a texture that will the icon of this item (path relative to data dir, just like PROP_ICON)
time_per_frame	Time (in seconds) to spend at each image.
badge	Whether to add badges to this item (bitmask, see possible values in widget.hpp)
image_path_type	How to interpret the path to the image (absolute or relative)

◆ addItem()

void DynamicRibbonWidget::addItem	(	const irr::core::stringw &	user_name,
		const std::string &	code_name,
		const std::string &	image_file,
		const unsigned int	badge = `0`,
		IconButtonWidget::IconPathType	image_path_type = `IconButtonWidget::ICON_PATH_TYPE_RELATIVE`
	)

Dynamically add an item to the ribbon's list of items (will not be visible until you call 'updateItemDisplay' or 'add').

Parameters

user_name	The name that will shown to the user (may be translated)
code_name	The non-translated internal name used to uniquely identify this item.
image_file	A path to a texture that will the icon of this item (path relative to data dir, just like PROP_ICON)
badge	Whether to add badges to this item (bitmask, see possible values in widget.hpp)
image_path_type	How to interpret the path to the image (absolute or relative)

◆ clearItems()

void DynamicRibbonWidget::clearItems ( )

Clears all items added through 'addItem'.

You can then add new items with 'addItem' and call 'updateItemDisplay' to update the display.

◆ elementRemoved()

void DynamicRibbonWidget::elementRemoved ( )

virtual

Callback from parent class Widget.

Reimplemented from GUIEngine::Widget.

◆ mouseHovered()

EventPropagation DynamicRibbonWidget::mouseHovered	(	Widget *	child,
		const int	playerID
	)

privatevirtual

used when you set eventSupervisors - see m_event_handler explainations below called when one of a widget's children is hovered.

Returns: 'EVENT_LET' if main event handler should be notified of a change, 'EVENT_BLOCK' otherwise

Reimplemented from GUIEngine::Widget.

◆ propagateSelection()

void DynamicRibbonWidget::propagateSelection ( )

private

Even though the ribbon grid widget looks like a grid, it is really a vertical stack of independant ribbons.

DynamicRibbonWidget is made of several ribbons; each of them thus has its own selection independently of each other.

When moving selection horizontally, this method is used to notify other rows above and below of which column is selected, so that moving vertically to another row keeps the same selected column.

To keep a grid feeling (i.e. you remain in the same column when pressing up/down), this method is used to ensure that all children ribbons always select the same column

◆ registerHoverListener()

void DynamicRibbonWidget::registerHoverListener ( DynamicRibbonHoverListener * listener )

Register a listener to be notified of selection changes within the ribbon.

Note: The ribbon takes ownership of this listener and will delete it.; The listener will be deleted upon leaving the screen, so you will likely want to add a listener in the "init" callback of your screen.

◆ setMaxLabelLength()

void GUIEngine::DynamicRibbonWidget::setMaxLabelLength ( int length )

inline

Set max length of displayed text.

◆ setSelection() [1/2]

bool DynamicRibbonWidget::setSelection	(	int	item_id,
		const int	playerID,
		const bool	focusIt,
		bool	evenIfDeactivated = `false`
	)

Select an item from its numerical ID.

Only for [1-row] combo ribbons.

Parameters

item_id In range [0 .. number of items added through 'addItem' - 1]

Returns: Whether setting the selection was successful (whether the item exists)

◆ setSelection() [2/2]

bool DynamicRibbonWidget::setSelection	(	const std::string &	item_codename,
		const int	playerID,
		const bool	focusIt,
		bool	evenIfDeactivated = `false`
	)

Select an item from its codename.

Returns: Whether setting the selection was successful (whether the item exists)

◆ setText()

void DynamicRibbonWidget::setText ( const irr::core::stringw & s )

virtual

Sets the text of a widget from a wchar_t.

Handy for many constant strings used in stk.

Note: Not all widgets use strings, so some widgets may ignore this text property; Changing the text property will only take effect the next time this widget is add()ed

Reimplemented from GUIEngine::Widget.

◆ sortItems()

template<typename Compare >

void GUIEngine::DynamicRibbonWidget::sortItems ( Compare comp )

inline

Sort the list of items with a given comparator.

◆ transmitEvent()

EventPropagation DynamicRibbonWidget::transmitEvent	(	Widget *	w,
		const std::string &	originator,
		const int	playerID
	)

privatevirtual

All widgets, including their parents (m_event_handler) will be notified on event through this call.

Must return whether main (GUI engine user) event callback should be notified or not. Note that in the case of a hierarchy of widgets (with m_event_handler), only the topmost widget of the chain decides whether the main handler is notified; return value is not read for others.

Reimplemented from GUIEngine::Widget.

Member Data Documentation

◆ m_ids

std::vector<int> GUIEngine::DynamicRibbonWidget::m_ids

private

irrlicht relies on consecutive IDs to perform keyboard navigation between widgets.

However, since this widget is dynamic, irrlicht widgets are not created as early as all others, so by the time we're ready to create the full contents of this widget, the ID generator is already incremented, thus messing up keyboard navigation. To work around this, at the same time all other widgets are created, I gather a number of IDs (the number of rows) and store them here. Then, when we're finally ready to create the contents dynamically, we can re-use these IDs and get correct navigation order.

◆ m_label_height

int GUIEngine::DynamicRibbonWidget::m_label_height

private

Height of ONE label text line (if label is multiline only one line is measured here).

If there is no label, will be 0.

◆ m_multi_row

bool GUIEngine::DynamicRibbonWidget::m_multi_row

private

Whether this ribbon can have multiple rows (i.e.

ribbon grid) or is a single line

◆ m_row_amount

int GUIEngine::DynamicRibbonWidget::m_row_amount

private

Number of rows and columns.

Number of columns can dynamically change, number of row is determined at creation

◆ m_rows

PtrVector<RibbonWidget, REF> GUIEngine::DynamicRibbonWidget::m_rows

Reference pointers only, the actual instances are owned by m_children.

Used to create multiple-row ribbons (what appears to be a grid of icons is actually a vector of stacked basic ribbons)
