Class TCastleEdit

Unit

Declaration

type TCastleEdit = class(TCastleUserInterfaceFont)

Description

Edit box to input a single line of text. The contents are in the Text property, you can get or set them at any time.

Note that you should set a suitable TCastleUserInterface.Width of the edit box, to nicely display a typical content. The height is by default auto-calculated (see AutoSizeHeight) looking at font size (and other properties, like padding and frame size), and usually is reasonable automatically.

Properties

Public property FocusedColor: TCastleColor read FFocusedColor write SetFocusedColor;

Focused text color. By default it's black.

Public property UnfocusedColor: TCastleColor read FUnfocusedColor write SetUnfocusedColor;

Unfocused text color. By default it's dark gray.

Public property PlaceholderColor: TCastleColor read FPlaceholderColor write SetPlaceholderColor;

Color for Placeholder. By default it's light gray.

Public property BackgroundColor: TCastleColor read FBackgroundColor write SetBackgroundColor;

Background color. Fills the area under Text and the padding. By default it's white. Note that it can be transparent, in which case it will show the tiEdit image underneath (if Frame is True), or UI control underneath (if Frame is False).

Public property AllowedChars: TSetOfChars read FAllowedChars write FAllowedChars;

Allowed characters that user can input. Note that this only restricts the user input, it does not prevent from programmatically setting Text to include disallowed characters.

Public property MaxLength: Cardinal read FMaxLength write FMaxLength;

Max length of user input. Value of 0 (default) means "no limit". Note that this only restricts the user input, it does not prevent from programmatically setting Text to be longer.

Published property Text: string read FText write SetText;

Currently input text.

Published property PaddingHorizontal: Single read FPaddingHorizontal write SetPaddingHorizontal default 0;

Inside the box rectangle, padding between the borders (or frame, if Frame) and text. Total horizontal padding is the sum PaddingHorizontal + Padding, total vertical padding is the sum PaddingVertical + Padding.

Published property PaddingVertical: Single read FPaddingVertical write SetPaddingVertical default 0;
 
Published property Padding: Single read FPadding write SetPadding default DefaultPadding;
 
Published property Frame: boolean read FFrame write SetFrame default true;

Draw frame around the box. Frame uses theme image tiEdit, see TCastleTheme.Images if you want to customize it.

Published property CaptureAllInput: boolean read FCaptureAllInput write FCaptureAllInput;

Should we capture input regardless of the currently focused control. This is in practice only sensible if this is the only edit box currently visible on the screen.

Published property AutoOnScreenKeyboard: Boolean read FAutoOnScreenKeyboard write FAutoOnScreenKeyboard default DefaultAutoOnScreenKeyboard;

When true, it shows the software keyboard on Android.

Published property AutoSizeHeight: Boolean read FAutoSizeHeight write SetAutoSizeHeight default true;
 
Published property Placeholder: String read FPlaceholder write SetPlaceholder;

Displayed when Text is empty.

Published property OnChange: TNotifyEvent read FOnChange write FOnChange;

Event sent when Text value was changed by a user. Note that this is not called when you change Text property programmatically.

Published property PasswordChar: Char read FPasswordChar write SetPasswordChar default #0;

Show given character (usually "*") instead of actual input characters. Useful for password input fields.

Published property FocusedColorPersistent: TCastleColorPersistent read FFocusedColorPersistent;

FocusedColor that can be visually edited in Castle Game Engine Editor, Lazarus and Delphi. Normal user code does not need to deal with this, instead read or write FocusedColor directly.
