Class BFlexComponent
The absolute minimum possible set of shared behaviour between FlexItem and FlexContainer.
(NB: FlexBuilder versions 0.1-2.0 had this class, but in reality the ideal is that they share ZERO code; v4 reinstated this for a very small number of features that really must be shared between them and shouldn't be accessed by external classes - because C# is so bad at permissions/privacy, this was the only way to give them a SHARED set of private internal methods and helper-classes)
Implements
Namespace: NinjaTools.FlexBuilder
Assembly: cs.temp.dll.dll
Syntax
public abstract class BFlexComponent : UIBehaviour, IFlexComponent, IUpgradeableComponentProperties
- (Boolean) _isContainerActiveAndEnabled
NOTE: this it to workaround ENORMOUS bugs in core Unity, whereby Unity's GameObject.isActiveSelf / GameObject.isActiveInHierarchy return INCORRECT VALUES when entering playmode in the editor. But .enabled (at least in Unity-2020+) is ALSO incorrect, in a way that allows us to infer the TRUE value of the GameObject.
Note: we are NEVER changing .enabled, it cannot change -- but Unity internally changes it while doing their callbacks! So we use that to 'detect' that they've disabled the object temporarilly)
- (RootFlexContainer) containingRootFlexContainer
Returns the innermost RootFlexContainer, i.e. the outermost part of this specific layout subtree, or null if this FlexContainer is not part of a rooted (i.e. valid/layouting) tree (which happens if e.g. this is a prefab of a partial layout).
- (String) hierarchicalName
Returns the fully-qualified name of this GameObject, by inserting the names of all its ancestors, separated by '.' - this makes it far easier to debug.
- (String) hierarchicalNameShortFirst
As for hierarchicalName but for especially long/deep hierarchies this is more human-readable: it places the current GameObject's name first, then adds the ancestor information afterwards
- (String) hierarchicalPath
As for hierarchicalName except it separates elements by '/', making it suitable for cases where you want a 'path' style name
- (FlexContainer) parentFlexContainer
Checks if there's a parent object, and it has a FlexContainer (note: does NOT return this.FlexContainer, we want the parent, not self
Use typically as: "if( OBJECT.parentFlexContainer is FlexContainer parentFC ) ... ".
If you prefer, use: "if( OBJECT.HasParentConainer( out var parentFC ) ) ..." - these are effectively identical, but this method lets you on-the-fly also check '...and was it an RFC?'
- (RectTransform) rectTransform
- (Version) versionCreatedBy
Which version of FlexBuilder originally created this component (mostly used for auto-upgrading and auto-fixing legacy bugs)
- (Version) versionUpgradedTo
Which version of FlexBuilder last upgraded this component (mostly used for auto-upgrading and auto-fixing legacy bugs)
Methods
- (Boolean) HasParentContainer(out FlexContainer)
Infinitesimally more efficient version of parentFlexContainer
Parameters
| FlexContainer | parentFC |
Returns
| Boolean |
- (void) OnGloballingEnteringPlayMode()
Unity's callback handler that we have to implement to fix major bugs in Unity's "RectTransform callbacks" system, which they now refuse to fix. Ignore it.
- (void) OnGloballingLeavingPlayMode()
Unity's callback handler that we have to implement to fix major bugs in Unity's "RectTransform callbacks" system, which they now refuse to fix. Ignore it.
- (void) SetAnchorsToCenter(GameObject)
Safe version of setting RectTransform anchoredPosition to "center" - this one suppresses the Unity callbacks that otherwise cause an infinite loop of re-positioning; always use this method instead of setting .anchoredPosition or .anchorMin or .anchorMax
Also note the bug in core Unity: RectTransform.anchorMax / anchorMin have a never-documented side-effect of corrupting the RectTransform size, so you must ONLY call this immediately BEFORE setting Size (not after!)
Parameters
| GameObject | go |
- (void) SetPosition(GameObject, Vector2)
Safe version of setting RectTransform.position - this one suppresses the Unity callbacks that otherwise cause an infinite loop of re-positioning; always use this method instead of setting .anchoredPosition
Parameters
| GameObject | go | |
| Vector2 | newPosition |
- (void) SetSizeSuppressingLayout(GameObject, Vector2)
Safe version of setting RectTransform.rect.size - this one suppresses the Unity callbacks that otherwise cause an infinite loop of re-positioning; always use this method instead of calling RectTransform.SetSizeWithCurrentAnchors
Parameters
| GameObject | go | |
| Vector2 | newSize |
