Libraries.Interface.Selections.TreeSelection

A selection represents what would be interacted with if the parent is used. The general idea of selection is common across user interface elements. For example, trees have a selection, which represents the item in the tree that the user is interacting with if the tree itself has a focus. Similarly, text boxes have a very different kind of selection, which represents which region of the text is being interacted with. Selection represents a generic way to get the name of the selection. In the case of TreeSelection, this returns a path of TreeItem objects, which can be traversed to learn the specific and unique path to the current tree selection. This path should be interpreted from high level to low level. For example, if we were selected on Game -> Player 1, then the TreeItem objects in the path would be Game first and Player 1 secon

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Example Code

Object o
        Object t
        integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smalle

This action empties the selection pat

This action determines if two objects are equal based on their hash code values.

Example Code

use Libraries.Language.Object
        use Libraries.Language.Types.Text
        Object o
        Text t
        boolean result = o:Equals(

This action gets the name that would be shown to the user.

Example Code

action SelectionChanged(Selection selection)
            output selection:GetDisplayName()
        e

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode

This action returns the item that contains the selection. It is not the selection itself.

Example Code

action SelectionChanged(Selection selection)
            Item theParentItem = selection:GetItem()
        e

This action gets the Path of the selection. This path should be interpreted from high level to low level. For example, if we were selected on Game -> Player 1, then the TreeItem objects in the path would be Game first and Player 1 second.

This action returns the selected TreeItem. This is the last TreeItem in the path. If the selection is empty, this will return undefined.

This action is used internally to set the selection owner.

This action sets up the component with default attributes.

This action returns true if there is no selection.

This action sends information that the selection was changed to all listener

This action is used internally to set the path on the Selection.

This action sets the name that would be shown to the user. It also changes the selection, triggering a SelectionEvent.

Example Code

action SelectionChanged(Selection selection)
            selection:SetDisplayName("A new name I want to change to")
        e
