Libraries.Interface.Controls.TextField Documentation

The TextField class is a control object and UI element it is added to the Game class. The TextField is used to represent a general text area that contains a single line of text.

Example Code

use Libraries.Interface.Forms.Form
use Libraries.Interface.Forms.Page
use Libraries.Interface.Controls.TextField
use Libraries.Game.Graphics.Color

class Main 
    action Main 
        Form form
        Page page = form:GetMainPage()

        TextField field
        Color color
        field:SetName("myTxt")
        field:SetBackgroundColor(color:Green())
        page:Add(field)

        form:Display()
    end
end

Actions Documentation

Activate(Libraries.Interface.Events.BehaviorEvent event)

Returns true if rendering the focus event.

Parameters

Activate()

This action returns a default behavior for this paricular control. Some controls do nothing by default, like a TextBox that responds to different kinds of input. Others, however, have default behaviors, like a Button or a MenuItem. If there is no default behavior, this action returns undefined.

Add(integer index, Libraries.Interface.Item2D newItem)

This action adds a different Item2D into this one, storing the added Item2D at a specific index in the internal array.

Example

use Libraries.Interface.Item2D

Item2D parentItem
Item2D child
parentItem:Add(0, child)

Add(Libraries.Interface.Item2D newItem)

This action adds a different Item2D into this one. This makes a few things happen. 1. The added item will get this item as its parent. 2. The added item's x and y coordinates will become relative to this Item. 3. Most actions on this Item will also affect the added Item.

Parameters

Dispose()

This action is used to free up any additional memory that is being used by this Item for purposes such as graphics. Note that the Item class doesn't have any extra memory that needs to be released with this action, but some classes which inherit from Item, such as Libraries.Game.Graphics.Drawable, do.

The Draw action is used to perform custom drawing on this Item and its children. This is only called during the Game engine's draw phase if this Item has enabled custom drawing via the SetCustomDrawing action. This is an advanced feature, and shouldn't be used by most users. If custom drawing is enabled, this action should be overriden -- if it isn't, the Item will attempt to provide default rendering for itself, its view, and its children, without regard to depth buffering. This action is responsible for instructing the provided Painter on how to draw this item, the view, and its children, and in what order to do so.

SetAccentColor(Libraries.Game.Graphics.ColorGroup value)

This action sets the accent color on the control.

Parameters

SetAcceptsMouseInput(boolean accepts)

Parameters

  • boolean accepts: True to set this Item to receive mouse events, or false to ignore them.

SetAccessibilityCode(integer newAccessibilityCode)

This action changes the accessibility code for this Item. This should be done with care because setting the accessiblity code to the incorrect type can cause accessibility to stop functioning or, in some cases, cause the program to crash.

Parameters

SetAccessibilityRoleDescription(text newRoleDescription)

This action sets a custom accessibility role description for this item. This should only be done if there is not a standard accessibility code for the type of item being implemented.

For example, if implementing an item that extends Control, is keyboard focusable, and responds to activation via both mouse clicks and the Space key, like a button, but it shouldn't be described as a button, then set the accessibility code to BUTTON and the custom role description to whatever is appropriate. If there isn't a suitable accessibility code, or if in doubt, set the accessibility code to CUSTOM.

Parameters

item:SetWidth(100)
item:SetHeight(100)
