Detailed Description

This class represents a diagram context, i.e. the data (a list of key/value pairs) of a diagram at a given time. It is notably used by titleblock templates to fetch the informations they need to do their rendering, or element for retrieve information about itself Key for element : label -> label or identification of element formula -> formula used to create the label (formula is make with variable) designation -> exhaustive comment used to explain what the element does. description -> exhaustive description used to explain what the element does. plant -> the plant assigned to the element comment -> a little comment wich can be displayed in the folio manufacturer -> the manufacturer of the element manufacturer_reference -> the manufacturer reference of the element quantity -> quantity of the element unity -> unity of the element auxiliary1 -> auxiliary 1 of element auxiliary2 -> auxiliary 2 of element machine_manufacturer_reference -> reference of the machine manufacturer supplier -> the supplier of the element function -> the function of element location -> the location assigned to the element frozenLabel -> label locked at a given time

add()

void DiagramContext::add

(

DiagramContext

other

)

DiagramContext::add Add all value of other to this. If a key already exist, the value is replaced. If a key doesn't exist, she will be added. All other keys of this context, which are not present in other, stay unchanged.

Parameters

addValue()

bool DiagramContext::addValue	(	const QString &	key,
		const QVariant &	value,
		bool	show = true
	)

Parameters

key	key to insert in the context - the key may only contain lowercase letters and dashes. If embedded key is set, key must be find it else value is not added.

Parameters

value	value to insert in the context
show	if value is used to be show on the diagram or somewhere else, we can specify if he is show(true) or not(false)

Returns

true if the insertion succeeds, false otherwise
