• 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.

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.

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.

This action sets how many rows this Control should be divided into when using a GridLayout. This will have no effect if this Control is not a container or if it is using a different layout. If this value is 0 or less, then the GridLayout will use its default grid height and ignore this value.

Parameters

• integer containerGridHeight

This action sets how many columns this Control should be divided into when using a GridLayout. This will have no effect if this Control is not a container or if it is using a different layout. If this value is 0 or less, then the GridLayout will use its default grid width and ignore this value.

Parameters

• integer containerGridWidth

• number topLeft: The rounding value to be applied to the top left corner, in pixels.
• number topRight: The rounding value to be applied to the top right corner, in pixels.

This action sets how much rounding to apply to the four corners of a rectangular control. The expected values are between 0 and 1, where 0 indicates no rounding, and 1 indicates full rounding. (If all four corners are set to have full rounding, the result will appear to be a circle.)

Parameters

• number bottomLeft: The rounding value to be applied to the bottom left corner (between 0 and 1).
• number bottomRight: The rounding value to be applied to the bottom right corner (between 0 and 1).
• number topLeft: The rounding value to be applied to the top left corner (between 0 and 1).
• number topRight: The rounding value to be applied to the top right corner (between 0 and 1).

The SetCustomDrawing action is used to indicate that this Item wants to directly manage how itself and its children are drawn. When this is set to true, the Item must be responsible for determining this 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.

Parameters

• boolean isCustom: True if this Item should use custom drawing, or false to use default drawing rules.
