Fields| Name | Description | |
|---|---|---|
 | AdjustMaxAutomatically |
If true, will adjust max value automatically based on entities in parent.
|
| AfterDraw | Callback to execute every frame after this entity is rendered. (Inherited from Entity.) |
| AfterUpdate | Callback to execute every frame after this entity updates. (Inherited from Entity.) |
| AttachedData | Optional data you can attach to this entity and retrieve later (for example when handling events). (Inherited from Entity.) |
| BeforeDraw | Callback to execute every frame before this entity is rendered. (Inherited from Entity.) |
| BeforeUpdate | Callback to execute every frame before this entity updates. (Inherited from Entity.) |
| ClickThrough |
If this boolean is true, events will just "go through" this entity to its children or entities behind it.
This bool comes to solve conditions where you have two panels without skin that hide each other but you want
users to be able to click on the bottom panel through the upper panel, provided it doesn't hit any of the first
panel's children.
(Inherited from Entity.) |
 | DefaultSize | Default scrollbar size for when no size is provided or when -1 is set for either width or height. |
| DefaultStyle | Default styling for vertical scrollbars. Note: loaded from UI theme xml file. |
| Disabled | If true, this entity and its children will be drawn in greyscale effect and will not respond to events. (Inherited from Entity.) |
| ExtraMargin |
Adds extra space outside the dest rect for collision detection.
In other words, if extra margin is set to 10 and the user points with its mouse 5 pixels above this entity,
it would still think the user points on the entity.
(Inherited from Entity.) |
| Identifier | Optional identifier you can attach to entities so you can later search and retrieve by. (Inherited from Entity.) |
| LimitDraggingToParentBoundaries | If true, users will not be able to drag this entity outside its parent boundaries. (Inherited from Entity.) |
| Locked | If true, this entity and its children will not respond to events (but will be drawn normally, unlike when disabled). (Inherited from Entity.) |
| OnClick | Callback to execute when user clicks on this entity (eg release mouse over it). (Inherited from Entity.) |
| OnFocusChange | Callback to execute every time this entity focus / unfocus. (Inherited from Entity.) |
| OnMouseDown | Callback to execute when mouse button is pressed over this entity (called once when button is pressed). (Inherited from Entity.) |
| OnMouseEnter | Callback to execute when mouse start hovering over this entity (eg enters its region). (Inherited from Entity.) |
| OnMouseLeave | Callback to execute when mouse stop hovering over this entity (eg leaves its region). (Inherited from Entity.) |
| OnMouseReleased | Callback to execute when mouse button is released over this entity (called once when button is released). (Inherited from Entity.) |
| OnMouseWheelScroll | Callback to execute when mouse wheel scrolls and this entity is the active entity. (Inherited from Entity.) |
| OnStartDrag | Called when entity starts getting dragged (only if draggable). (Inherited from Entity.) |
| OnStopDrag | Called when entity stop getting dragged (only if draggable). (Inherited from Entity.) |
| OnValueChange | Callback to execute when entity value changes (relevant only for entities with value). (Inherited from Entity.) |
| OnVisiblityChange | Callback to execute every time the visibility of this entity changes (also invokes when parent becomes invisible / visible again). (Inherited from Entity.) |
| PromiscuousClicksMode | If in promiscuous mode, mouse button is pressed *outside* the entity and then released on the entity, click event will be fired.
If false, in order to fire click event the mouse button must be pressed AND released over this entity (but can travel outside while being
held down, as long as its released inside).
Note: Windows default behavior is non promiscuous mode. (Inherited from Entity.) |
| ToolTipText |
Optional tooltip text to show if the user points on this entity for long enough.
(Inherited from Entity.) |
| UseActualSizeForCollision |
If true (default), will use the actual object size for collision detection. If false, will use the size property.
This is useful for paragraphs, for example, where the actual width is based on text content and can vary and be totally
different than the size set in the constructor.
(Inherited from Entity.) |
| WhileDragging | Called every frame while the entity is being dragged. (Inherited from Entity.) |
| WhileMouseDown | Callback to execute every frame while mouse button is pressed over the entity. (Inherited from Entity.) |
