Font Class

Well I came to the city...
I was running from the past.
My heart was bleeding...
And it hurt my bones to laugh.

aztec.ui.Font

public class Font from<Base>

Base

Font

The Font class represents a text font which can be used to draw text. The font can be attached to any window to specify the appearance of text within that window. The name of the font and the point size (8, 10, 12, etc.) is used when creating the font. The class also provides an IsValid() method to indicate whether the font name and point size were valid when creating the font.

 

Note that a Font object uses UI system resources which are limited by the OS. It works most efficiently when allocated once and then used each time a window needs to be redrawn. If used in a Canvas control, allocating a new Font object every time a window has to be redrawn could eventually cause UI resources to run out.

 

The Font object also registers a font resource with the Display with which it will be used (which is passed into the constructor). If the Font is used to write or draw on a Display other than the one for which it was created, a DisplayException will be fired.

Display()

public method<Display> Display()

Parameters

None

Return Value

Returns reference to Display object

Description

This method returns the reference to the Display object where the Font was created (the Display that was passed into the constructor). If a null was passed into the constructor, the local display is used, and this method returns the reference to the local Display object.

 

A Font resource is created within the context of a Display, and it can only be used with that Display. If a Font is used with a Display where it was not created, a DisplayException will be fired.
