Element: Text.

Text: An interactive string.
Description: A Text is a drawing element that displays a string at given coordinates of the parent drawing panel. The string is drawn with the specified font.
Texts admit subscripts and superscripts, as well as greek letters. Thus, setting the text to F_{N} = m$\omega$^{2}R results in the following display.
Texts respond to user interaction on their position coordinates (changing their position), invoking up to three different actions. The precise drawing position of the geometrical shape with respect to the given coordinates can be chosen among several standard values.

Name | Description | Values accepted |
Position and Size | ||
X | The X coordinate of the element. | Any constant or variable of type double or int. |
Y | The Y coordinate of the element. | Any constant or variable of type double or int. |
Z | The Z coordinate of the element. | Any constant or variable of type double or int. |
Visibility and Interaction |
||
Visible | The visibility of the element. | A boolean variable or one of the constants true or false. |
Enabled | Whether the element responds to user interaction. | A boolean variable or one of the constants true or false. |
Actions |
||
On Press | The action to invoke when the element is pressed. | The Java code to invoke for the action. |
On Drag | The action to invoke when the element is moved. | The Java code to invoke for the action. |
On Release | The action to invoke when the element is released. | The Java code to invoke for the action. |
On Enter | The action to invoke when the pointer enters the element. | The Java code to invoke for the action. |
On Exit | The action to invoke when the pointer leaves the element. | The Java code to invoke for the action. |
Graphical Aspect | ||
Text | The string with the text to draw. | Any constant or variable of type String. |
Position | The exact drawing position of the string relative to the element's coordinates. | One of the following constants:
Integer constants and variables are also accepted, using any of the values indicated in the parentheses above. This allows changing the position in run-time. |
Rotate | The (counter-clockwise) rotation angle to apply to the element. | A constant or variable of type double for an angle in radians, or a constant or variable of type int for an angle in degrees. |
Color | The color used to draw the element. | An Object variable of the class java.awt.Color
or one of the predefined colors: black,
blue, cyan, darkGray, gray, green, lightGray, magenta, orange, pink,
red, white, yellow.
A color can also be specified providing its integer RGB coordinates (between 0 and 255), plus an optional transparency coordinate. The default value is decided by the system. |
Font | The font used for the text displayed by the element. | An Object variable of the class java.awt.Font
or a set of family, style and size, separated by commas. The style
must be one of plain,
bold, italic, bold | italic. Example: Monospaced,italic,18.
The default value is decided by the system. |
