Detailed Description

The password field component.

This control allows the user to secretly enter a password and supports an optional horizontal scrollbar.

Each key typed will display a # character, but the user can specify another character.

Unlike a text field it does not support text selection or the copying and pasting of text via the clipboard.

Fires CHANGED, ENTERED, LOST_FOCUS, GETS_FOCUS events.
The focus events are only fired if the control is added to a GTabManager object.

float  p3 
)

Create a password field without a scrollbar.

Parameters
theAppletthe main sketch or GWindow control for this control
p0x position based on control mode
p1y position based on control mode
p2x position or width based on control mode
p3y position or height based on control mode

String g4p_controls.GPassword.getPassword ( )

Get the current password (hidden) value of this field.

Returns
actual password text

◆ getSnapshot()

PGraphics g4p_controls.GPassword.getSnapshot ( )

This method should be used sparingly since it is heavy on resources.

Returns
a PGraphics object showing current state of the control (ignoring rotation)

Reimplemented from g4p_controls.GAbstractControl.
