Returns:

• Boolean — true if the item matches all the criteria, false otherwise

See also:

• getItems(match)

Checks whether the item matches the given criteria. Extended matching is possible by providing a compare function or a regular expression. Matching points, colors only work as a comparison of the full object, not partial matching (e.g. only providing the x-coordinate to match all points with that x-value). Partial matching does work for item.data.

See project.getItems(match) for a selection of illustrated examples.

Parameters:

Fetch the descendants (children or children of children) of this item that match the properties in the specified object. Extended matching is possible by providing a compare function or regular expression. Matching points, colors only work as a comparison of the full object, not partial matching (e.g. only providing the x- coordinate to match all points with that x-value). Partial matching does work for item.data.

Matching items against a rectangular area is also possible, by setting either match.inside or match.overlapping to a rectangle describing the area in which the items either have to be fully or partly contained.

See project.getItems(match) for a selection of illustrated examples.

Options:

• match.recursive: Boolean — whether to loop recursively through all children, or stop at the current level — default: true
• match.match: Function — a match function to be called for each item, allowing the definition of more flexible item checks that are not bound to properties. If no other match properties are defined, this function can also be passed instead of the match object
• match.class: Function — the constructor function of the item type to match against
• match.inside: Rectangle — the rectangle in which the items need to be fully contained
• match.overlapping: Rectangle — the rectangle with which the items need to at least partly overlap

Parameters:

• match: Object⟋Function — the criteria to match against

Returns:

• Array of Item objects — the list of matching descendant items

See also:

• matches(match)

Extended matching is possible by providing a compare function or regular expression. Matching points, colors only work as a comparison of the full object, not partial matching (e.g. only providing the x- coordinate to match all points with that x-value). Partial matching does work for item.data. See project.getItems(match) for a selection of illustrated examples.

Parameters:

• match: Object⟋Function — the criteria to match against

Transform the item.

Parameters:

• matrix: Matrix — the matrix by which the item shall be transformed

Converts the specified point from global project coordinate space to the item’s own local coordinate space.

Parameters:

• point: Point — the point to be transformed

Returns:

• Point — the transformed point as a new instance

Converts the specified point from the item’s own local coordinate space to the global project coordinate space.

Parameters:

• point: Point — the point to be transformed

Returns:

• Point — the transformed point as a new instance

Converts the specified point from the parent’s coordinate space to item’s own local coordinate space.

Parameters:

• point: Point — the point to be transformed

Returns:

• Point — the transformed point as a new instance

Converts the specified point from the item’s own local coordinate space to the parent’s coordinate space.

Parameters:

• point: Point — the point to be transformed

Returns:

• Point — the transformed point as a new instance

Transform the item so that its bounds fit within the specified rectangle, without changing its aspect ratio.

Parameters:

• rectangle: Rectangle
• fill: Boolean — optional, default: false

Example:Fitting an item to the bounding rectangle of another item's bounding rectangle:

Example:Fitting an item to the bounding rectangle of another item's bounding rectangle with the fill parameter set to true:

Example:Fitting an item to the bounding rectangle of the view

Attaches an event handler to the item.

Parameters:

• type: String — the type of event: ‘frame’, mousedown’, ‘mouseup’, ‘mousedrag’, ‘click’, ‘doubleclick’, ‘mousemove’, ‘mouseenter’, ‘mouseleave’
• function: Function — the function to be called when the event occurs, receiving a MouseEvent or Event object as its sole argument

Returns:

• Item — this item itself, so calls can be chained

Example:Change the fill color of the path to red when the mouse enters its shape and back to black again, when it leaves its shape.

Attaches one or more event handlers to the item.

Parameters:

• object: Object — an object literal containing one or more of the following properties: frame, mousedown, mouseup, mousedrag, click, doubleclick, mousemove, mouseenter, mouseleave

Returns:

• Item — this item itself, so calls can be chained

Example:Change the fill color of the path to red when the mouse enters its shape and back to black again, when it leaves its shape.

Example:When you click the mouse, you create new circle shaped items. When you move the mouse over the item, its fill color is set to red. When you move the mouse outside again, its fill color is set black.

Detach an event handler from the item.

Parameters:

• type: String — the type of event: ‘frame’, mousedown’, ‘mouseup’, ‘mousedrag’, ‘click’, ‘doubleclick’, ‘mousemove’, ‘mouseenter’, ‘mouseleave’
• function: Function — the function to be detached

Returns:

• Item — this item itself, so calls can be chained

Detach one or more event handlers to the item.

Parameters:

• object: Object — an object literal containing one or more of the following properties: frame, mousedown, mouseup, mousedrag, click, doubleclick, mousemove, mouseenter, mouseleave

Returns:

• Item — this item itself, so calls can be chained

Emit an event on the item.

Parameters:

• type: String — the type of event: ‘frame’, mousedown’, ‘mouseup’, ‘mousedrag’, ‘click’, ‘doubleclick’, ‘mousemove’, ‘mouseenter’, ‘mouseleave’
• event: Object — an object literal containing properties describing the event

Returns:

• Boolean — true if the event had listeners, false otherwise

Check if the item has one or more event handlers of the specified type.

Parameters:

• type: String — the type of event: ‘frame’, mousedown’, ‘mouseup’, ‘mousedrag’, ‘click’, ‘doubleclick’, ‘mousemove’, ‘mouseenter’, ‘mouseleave’

Returns:

• Boolean — true if the item has one or more event handlers of the specified type, false otherwise
