Libraries.Interface.Controls.TextBox

Returns true if rendering the focus event.

Parameters

• Libraries.Interface.Events.BehaviorEvent

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.

Parameters

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

Parameters

• integer index
• Libraries.Interface.Item2D

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

• Libraries.Interface.Item2D

This action adds a new Behavior to this Item.

Parameters

• Libraries.Interface.Behaviors.Behavior

This action removes an Item2D at a specifed index from the internal array.

Parameters

Return

boolean: True if this Item can receive mouse events, or false otherwise.

This action returns the nearest parent object that is accessible. This can be anything that the programmer wants to be accessible, from user interface components in a 2D interface to 3D components relative in 3-space on screen. By default, items have no accessible parent and are self-contained, but user interface components normally override the behavior so that controls can be logically nested within each other. attribute: returns Item

Return

boolean:

The IsClipping action returns true if pixel clipping is enabled, or false if it is disabled. If it is enabled, when the Item and its children are drawn as part of the QueueForDrawing action, any pixels that would be drawn outside of the unrotated dimensions of the Item are not rendered. In other words, the Item will only draw inside the exact rectangle formed by its x, y position and its width and height.

Return

boolean: Whether or not pixel clipping is enabled for this Item.

This action determines whether this item is collidable.

Return

boolean: True if this item is collidable, false otherwise

The IsCustomDrawing action returns whether or not this Item is directly managing how itself and its children are drawn. When this value is true, the Item is responsible for determining its rendering via the Draw(Painter2D) action -- if this action isn't overridden, the Item and its children won't be drawn. This is an advanced feature only necessary for complex custom components, and most users will not need to use this functionality.

Return

boolean: Whether or not this Item is currently using custom drawing rules.

This action returns whether or not any items are contained in this Item.

Return

boolean:

This action sets this item's angular velocity in radians per second. Physics must be enabled in this item before using this action.

Return

boolean:

This action will return if the Item2D is currently flipped across the x-axis.

Return

boolean:

This action will return if the Item2D is currently flipped across the y-axis.

Return

boolean:

This action returns whether or not the Item can currently receive focus. This property can be set with SetFocusable().

Return

boolean:

The IsFocused action determines if this Item is currently focused, returning true if it is, or false if it is not.

Return

boolean:

This flag tells the textbox to move the focus on a tab, as opposed to doing indentation. This thus directly turns off the indentation manager.

Return

boolean:

This action gets the number of broadphase nodes this item has. This action is used internally and users should not need to use this action.

Return

boolean: The number of broadphase nodes attached to this item

This action returns true if the item has been added to a Layer, or false otherwise.

Return

boolean: True if the item is on a Layer, or false otherwise.

This action determines whether physics is currently enabled for this item.

Return

boolean: True if physics is enabled for this item, false otherwise

This action determines if the TextBox should place characters so that they're touching the base line. In practice, if this is true, the TextBox will position characters slightly lower, providing more whitespace above the first line. If this value is false, the characters will be positioned higher, which may look better for TextBoxes that are approximately one line in height. The default value is true.

Return

boolean:

Returns true if rendering the focus event.

Return

boolean:

Returns true if rendering the mouse down event.

Return

boolean:

Returns true if rendering the mouse over event.

Return

boolean:

Returns true if rendering the selection event.

Return

boolean:

This action sets this item to be collidable. Passing true turns on collision for this item while passing false turns off collision for this item.

Return

boolean:

This action determines whether physics is currently enabled for this item.

Return

boolean: True if physics is enabled for this item, false otherwise

This action returns whether the Item is currently set to be visible on the screen.

Return

boolean: A boolean representing whether or not the Item is currently visible.

This action translate a pixel value to a percentage scroll Y value. The pixel value is relative to the Spreadsheet.

Return

boolean:

This action returns a percentage (represented between 0 and 1) indicating how much of the content's height can be viewed in the scrollable region. For example, if the content is 400 pixels tall and the scrollable region is 100 pixels tall, the percent of viewable height returned will be 0.25. This value cannot be set directly. It is calculated from the dimensions of the content and the Control.

Return

boolean:

This action gets the position of the center of this item in local coordinates (i.e., with respect to itself).

Return

boolean: The vector representing the center of this item in local coordinates

This action sets the x-component of this item's linear velocity in units per second. Physics must be enabled on this item before using this action.

Return

boolean:

This action creates the nodes for this item for the broadphase collision. This action is needed in order to add the item to the collision detection system. This action is used internally and users should not need to use this action.

Return

boolean:

This action is used to load the graphical components of the Control. This is handled automatically by the Game engine as needed, and most users shouldn't need to use this action directly.

Checks to see if the Item2D's internal vertices are up to date, and updates them if they are not. This is used primarily internally to ensure that the item's vertices are properly aligned before use, e.g. to project an image on the screen at the coordinates of the vertices. Most users will never need to use this action directly.

This action takes a gesture event and handles it. It will first test to see if the gesture event took place within the bounds of this Item. If so, it will notify any GestureListeners of the event. If the event was not contained within this Item, or if there are no GestureListeners on this Item, the Item will ask its parent Item to process the event, if there is a parent.

Parameters

Parameters

• Libraries.Interface.Events.TouchEvent

This action is used to draw this Item on the screen, and then draw all of the Item's children hierarchy on the screen. Note that Items themselves can not be drawn, but some classes that extend the Item class, such as the Libraries.Game.Graphics.Drawable class, can be. To see how they draw, see their documentation.

Parameters

• Libraries.Game.Graphics.Painter2D

This action inserts the provided text at the requested global text index. This action does not move the caret and has no otherwise visual impact.

Parameters

• Libraries.Interface.Events.GestureListener

The DeleteForward action deletes a portion of the text, as if the user had just pressed the delete key. If a portion of text is selected, the selection will be deleted -- otherwise, the character immediately following the caret will be deleted.

Parameters

• integer index

The ideal long-term solution is to have each line in the MultipleLineText class maintain its width, which is updated during changes. Then finding the width is O(n) for n lines. Currently that class only maintains text for monospaced fonts, so we calculate from that for now. This approach only works due to the constrained conditions of the first version of this TextBox: - All of the text is styled with a single font. - The text is monospaced. If it isn't, we attempt to err on the side of too much space, rather than not enough.

Returns true if rendering the mouse over event.

This action requests that this Control should be laid out by its container (or the Layer2D if there is no containing Control) during the next Update.

This action requests that this Control (as well as all of its descendents) should reload their graphics during the next Update.

This action informs the engine that this Item needs to recalculate its vertex values before they can be used (most commonly, to be drawn to the screen). Most users will never need to call this directly. If you are using a custom ShaderProgram with this Item, you can use this action to indicate that the shader mapping should reset the vertex values for this Item before its drawn again.

This action sets the y-component of this item's linear velocity in units per second. Physics must be enabled on this item before using this action.

Parameters

• boolean flag

This action is used to indicate that the Control no longer needs to be laid out. This is called internally by the system as needed, and shouldn't be necessary for most users.

This action sets the mass, mass moment of inertia, and how the 2D item should move (via linear velocity) to be at the desired location.

The Resize action is used to recalculate the size and position of Controls that are being controlled by a Layout. Calling Resize on an Item2D won't have a direct effect on it, but if the Item's children hierarchy contains any Controls, those Controls will be resized.

Rotates this Item2D by the given number of degrees. This will also rotate all Items in the children hierarchy of this Item.

Parameters

• number degrees

This action will multiply the current scaling value by the given number. A parameter of 0 or less will be ignored.

Parameters

• number xAmount
• number yAmount

This action will multiply the current scaling value by the given number. A parameter of 0 or less will be ignored. This action will increase or decrease the scale of the object from the center, and update the Item's x,y coordinates to reflect the new bottom-left corner of the Item.

Parameters

• number amount

This action will multiply the current scaling values of the x and y planes by the given number. A parameter of 0 or less will be ignored. This action will increase or decrease the scale of the object from the center, and update the Item's x,y coordinates to reflect the new bottom-left corner of the Item.

Parameters

• Libraries.Interface.Events.MouseEvent

Force a recalculation of the width by setting its value to -1.

Parameters

• integer startIndex

This action selects an item in the Control using first letter navigation, if the Control supports it. If the Control doesn't support first letter navigation, this will do nothing.

Parameters

• text firstLetter

This action sets the accent color on the control.

Parameters

• Libraries.Game.Graphics.ColorGroup: the accent control.

This action sets whether or not this Item accepts mouse input. If set to true, this will intercept incoming mouse events, triggering any related MouseListeners and InputSets and preventing the mouse event from propagating to other Items on the Layer. The default value is true.

Parameters

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

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

• integer newAccessibilityCode: the new accessibility code for this Item.

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. If the item behaves very similarly to a standard control type, then set the accessibility code to that standard type while also setting the role description. 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

• text newRoleDescription: the new custom role description for this Item.

This action gets the rotational inertia of this item. The inertia is in kilogram units squared.

Parameters

This action sets how far the view of content should be scrolled along the y-axis. In other words, it's a percentage represented between 0 and 1 indicating how far the vertical scroll bar should be moved downwards. This percentage represents the position of the start of the scroll bar. For example, a scroll percent of 0.4 indicates that the view begins 40% of the way through the scrollable area.

Parameters

• integer barThickness

This action sets the border color of the control.

Parameters

• Libraries.Game.Graphics.ColorGroup: the border color.

This action sets the border style either, LayoutProperties.TOP, LayoutProperties.BOTTOM, LayoutProperties.LEFT, LayoutProperties.RIGHT, and LayoutProperties.ALL.

Parameters

• integer style

This action sets the border thickness on the control.

This action sets how long it takes for the caret to cycle between visible and hidden when the caret is idle. The time provided describes the number of seconds it takes to transition from one stage to another -- e.g., if the provided time is one second, the caret will remain visible for one second, then hide for one second, and so on.

Parameters

• number time: The number of seconds the caret should wait before cycling between visible and hidden while idle.

This action sets the number of seconds the caret should wait before automatically moving when the user presses and holds a movement key.

Parameters

• number time: The number of seconds a user must hold a movement key before the caret moves automatically.

This action sets the number of seconds it should take for the caret to move a single character when the caret is automatically moving due to the user pressing and holding a movement key.

Parameters

• number time: The number of seconds it takes for an automatically moving caret to move a single character.

The SetCaretPosition action places the caret at the requested global index within the text of the TextBox. Note that if the index requested would be in the middle of a line separator, the caret will be placed at the end of the line separator on the next line, which can cause the actual index of the caret to be slightly higher. If the selection is locked to a region, attempting to set the caret to a position outside of the lock will instead go to the appropriate end of the locked region instead.

Parameters

• integer index

The SetCaretPositionToLine action sets the caret to the beginning of the specified line.

Parameters

• integer line

This action will set the X and Y coordinates of the Item so that the center of the Item is located at the given X, Y coordinates.

This action will set the Y coordinate of the Item so that the center of the Item is aligned with the given Y coordinate value.

Parameters

• number setY

The SetChildrenProcessingMouseEvents action is used to set whether or not children items should receive mouse events if this Item is using custom drawing. This affects only custom drawing Items -- if the Item isn't drawing, children objects will always receive the mouse events first. This value is false by default. This is an advanced feature only necessary for complex custom components, and most users will not need to use this.

Parameters

• boolean shouldProcess

This action sets the clipping coordinates of the given painter to respect the coordinates of this Item (if it's clipping) as well as any clipping being performed by parent Items. This action is called automatically by the Game engine as necessary, and most users will never need to use this action directly.

Parameters

• Libraries.Game.Graphics.Painter2D

The SetClipping action is used to enable or disable clipping. If it is enabled, when the Item and its children are drawn as part of the QueueForDrawing action, any pixels that would be drawn outside of the unrotated dimensions of the Item are not rendered. In other words, the Item will only draw inside the exact rectangle formed by its x, y position and its width and height.

Parameters

• boolean clip: True to enable pixel clipping, false to disable.

This action sets this item to be collidable. Passing true turns on collision for this item while passing false turns off collision for this item.

Parameters

• boolean flag: Whether or not to turn collision on for this item

This action gets the position of the item in physics space from the previous frame. This action is used internally and users should not need to use this action

Parameters

• boolean flag

This action sets the total torque on this item. The units are kilogram units squared per second per second. This action should be used to set the total torque on this item. If we want to apply a torque to this item, we should use the ApplyTorque actions instead. Physics must be enabled on this action before using this action.

Parameters

• boolean flag

This action sets the total force on this item. The units are kilogram units per second per second. This action should be used to set the total force on this item. If we want to apply a force to this item, we should use the ApplyForce actions instead. Physics must be enabled on this item before using this action.

Parameters

• integer index

This is an action used internally by the physics system to keep track of the collisions with this item in a linked list structure. This action sets the head of the linked list of collisions to the passed CollisionEdge2D object. This action is used internally and users should not need to use this action.

Parameters

• Libraries.Game.Collision.CollisionEdge2D: The new head of the linked list of collisions
