This page contains descriptions of terms found within the EiffelBuild documentation.
|
|
|
|
==Object==
|
|
|
|
An EiffelBuild object is a representation of a Vision2 component and its properties. When developing with EiffelBuild, you manipulate objects to build the desired interface.
|
|
|
|
Each object type has a different set of properties that may be manipulated, and these correspond directly to the properties available within the [[EiffelVision Introduction|EiffelVision 2]] type. There is property which is specific to an EiffelBuild object, '''Name''' which is used for your identification purposes and as the attribute name in the generated code.
|
|
|
|
For more information on manipulating objects within EiffelBuild, see:
|
|
* How to [[Create an object|create an object]]
|
|
* How to [[Reparent an Object| reparent an object]] .
|
|
* [[Object editor|Object editor]] for details on modifying object properties.
|
|
|
|
Within EiffelBuild, there may be multiple views of a single object displayed simultaneously. Any modifications to an object will immediately update all views. Both the [[Layout constructor| layout constructor]] and the [[Builder window|builder window]] provide views of the objects within your project, and in these, the objects may be manipulated. The [[Display window|display window]] also provides a view of the objects in your system, except the objects cannot be manipulated from this view. It can be thought of as a preview of the project you are developing.

|
|
==Component==
|
|
|
|
EiffelBuild components are templates representing user defined object structures. From a component, you can quickly build a matching structure of objects. Components are available in EiffelBuild so that you do not repeatedly create the same structures over and over again while developing your projects.
|
|
|
|
You specify a new component by creating it from an existing object structure. See [[Component selector| component_selector]] for more detailed instructions on the use of components.
|
|
|
|
To view an existing component, use the [[Component viewer|component_viewer]] .
|
|
|
|
It is not possible to modify a component once created, except to [[Component selector| delete]] it.
|
|
<span id="pick_and_drop"></span>
|
|
==Pick and Drop==
|
|
|
|
The pick and drop mechanism is one of Eiffel Software 's exclusive technologies and is provided by [[EiffelVision Introduction|EiffelVision 2]] . In EiffelBuild, it allows you to easily send data from a component of the interface to another.
|
|
|
|
You can '''Pick''' a reference to a '''development object''', such as an object or component with a single click of the '''right''' mouse button. Then as you start moving the mouse around - not pressing any of its buttons - a pebble tracks the cursor position, and a line continuously connects the pebble to the object's original position.
|
|
|
|
You may terminate this situation in either of two ways:
|
|
* If the pebble you are dragging is the regular cursor, you can right-click again to confirm the pick-and-drop and so effectively send the dragged development object to the targeted component. This is known as '''Dropping'''.
|
|
Right-clicking when the pebble is the '''no''' cursor, will only stop the pick-and-drop because the component you are hovering with the mouse does not accept your development object.
|
|
|
|
* If, for any reason, you change your mind, you can cancel the pick-and-drop by left-clicking anywhere or by pressing the Escape key.
