Class TextField

Namespace

MLEM.Ui.Elements

Assembly

MLEM.Ui.dll

A text field element for use inside of a UiSystem. A text field is a selectable element that can be typed in, as well as copied and pasted from. If an on-screen keyboard is required, then this text field will automatically open an on-screen keyboard using OpenOnScreenKeyboard(string, string, string, bool). This class interally uses MLEM's TextInput.

Properties

CaretLine

The line of text that the caret is currently on. This can only be only non-0 if Multiline is true.

public int CaretLine { get; }

Property Value

int

CaretPos

The position of the caret within the text. This is always between 0 and the Length of Text

public int CaretPos { get; set; }

Property Value

int

CaretPosInLine

The position in the current CaretLine that the caret is currently on. If Multiline is false, this value is always equal to CaretPos.

public int CaretPosInLine { get; }

Property Value

int

Font

The font that this text field should display text with

public StyleProp<GenericFont> Font { get; set; }

Property Value

StyleProp<GenericFont>

MaskingCharacter

A character that should be displayed instead of this text input's Text content. The amount of masking characters displayed will be equal to the Text's length. This behavior is useful for password inputs or similar.

public char? MaskingCharacter { get; set; }

Property Value

char?

MaximumCharacters

The maximum amount of characters that can be input into this text input. If this is set, the length of Text will never exceed this value.

public int? MaximumCharacters { get; set; }

Property Value

int?

Multiline

Whether this text input should support multi-line editing. If this is true, pressing Microsoft.Xna.Framework.Input.Keys.Enter will insert a new line into the Text if the InputRule allows it. Additionally, text will be rendered with horizontal soft wraps, and lines that are outside of the text input's bounds will be hidden.

public bool Multiline { get; set; }

Property Value

bool

Text

This text input's current text

public string Text { get; }

Property Value

string

TextScale

The scale that this text field should render text with

Property Value

StyleProp<float>

Methods

Draw(GameTime, SpriteBatch, float, SpriteBatchContext)

Draws this element and all of its children. Override this method to draw the content of custom elements. Note that, when this is called, SpriteBatch.Begin has already been called with custom Transform etc. applied.

public override void Draw(GameTime time, SpriteBatch batch, float alpha, SpriteBatchContext context)

Parameters

time GameTime

The game's time

batch SpriteBatch

The sprite batch to use for drawing

alpha float

The alpha to draw this element and its children with

context SpriteBatchContext

The sprite batch context to use for drawing

InitStyle(UiStyle)

Initializes this element's StyleProp<T> instances using the ui system's UiStyle.

protected override void InitStyle(UiStyle style)

Parameters

style UiStyle

The new style

InsertText(object, bool)

Inserts the given text at the CaretPos. If the resulting Text exceeds MaximumCharacters, the end will be cropped to fit.

public void InsertText(object text, bool removeMismatching = false)

Parameters

text object

The text to insert

removeMismatching bool

If any characters that don't match the InputRule should be left out

RemoveText(int, int)

Removes the given amount of text at the given index

public void RemoveText(int index, int length)

Parameters

index int

The index

length int

The amount of text to remove

SetAreaAndUpdateChildren(RectangleF)

Sets this element's Area to the given RectangleF and invokes the OnElementAreaUpdated event. This method also updates all of this element's Children's areas. Note that this method does not take into account any auto-sizing, anchoring or positioning, and so it should be used sparingly, if at all.

public override void SetAreaAndUpdateChildren(RectangleF area)

Parameters

area RectangleF
