Entities and Objects: Description of Objects: Area

The areas are a new type of object graph, which allows to draw colored rectangular areas with the opportunity to view a text on the inside, this type of object is useful for instance to define groups of objects in the diagram relating a particular type or function inside the database. These objects have properties not active, or exercise any influence on objects contained in the draft, and can be defined independently of any display of the project. For each area, you can define the fill color and, optionally, a line of text as a description of what you want to enclose. Creating object in selecting the panel instruments, from the main menu or from the popup menu by pressing the left mouse button in a chart displaying and dragging the cursor to the size desired; releasing the button will set the final coordinated. During building, appear on the chart the new area (initially gray color), which constantly monitor the design phase, so as to enable the user to verify in real time the actual size. It should be borne in mind that, for practical reasons, the areas with smaller sides of 50 pixels per side will be automatically eliminated, why not considered useful and to eliminate the possibility of creating invisible objects (such as an object from 1x1 pixels) that could create problems for their cancellation. Then you can change the settings of the new business double-click with the left mouse button on himself, who will present a dialog with the current ownership of the new item. At any time you can move or resize a subject area: in the first case, as with other types of object, just select the object with the mouse and holding down the right button, drag the graphic element to the position desired, in the second case, the size can be changed by dragging the edges or bottom right until he reaches the desired size.

The figure below shows the window is to modify an object Area. Like all objects, the window presents a field where you must enter a unique name in the draft.

The "Text" lets you enter a description, that note will be displayed in the upper left corner inside the graph. Optionally, you can highlight the text in bold, acting on the check.

In correspondence of the "Color" is a button that represents the current background color of the object, pressing this button will access the window for selecting colors, to change the current setting.

In addition to the above settings, you can manually define the position and size of the chart, entering the coordinates corresponding directly at the top left corner of the object and its size width and height.

Any such change will be effected reflected in the diagram of the project to close the window change.
