class PopUpTreeGridView
package com.feathersui.controls
extends FeathersControl
implements IStageFocusDelegate, IDataSelector<Dynamic>
Displays a Button
that may be triggered to display a TreeGridView
as a
pop-up. The tree grid view may be customized to display in different ways,
such as a drop-down, inside a Callout
, or as a modal overlay.
The following example creates a pop-up tree, gives it a data provider, tells the item renderer how to interpret the data, and listens for when the selection changes:
var popUpTreeGridView = new PopUpTreeGridView();
popUpTreeGridView.dataProvider = new ArrayHierarchicalCollection([
{
dept: "Bakery",
children: [
{item: "Whole Wheat Bread", dept: "Bakery", price: "2.49"},
{item: "English Muffins", dept: "Bakery", price: "2.99"},
]
},
{
dept: "Dairy",
children: [
{item: "2% Milk", dept: "Dairy", price: "2.49"},
{item: "Butter", dept: "Dairy", price: "4.69"},
]
},
{
dept: "Meat",
children: [
{item: "Chicken breast", dept: "Meat", price: "5.90"},
{item: "Bacon", dept: "Meat", price: "4.49"},
]
},
{
dept: "Produce",
children: [
{item: "Lettuce", dept: "Produce", price: "1.29"},
{item: "Broccoli", dept: "Produce", price: "2.99"},
]
},
], (item:Dynamic) -> item.children);
popUpTreeGridView.columns = new ArrayCollection([
new TreeGridViewColumn("Department", (data) -> data.dept),
new TreeGridViewColumn("Item", (data) -> data.item),
new TreeGridViewColumn("Unit Price", (data) -> data.price)
]);
popUpTreeGridView.itemToText = (item:Dynamic) -> {
if (popUpTreeGridView.dataProvider.isBranch(item)) {
return item.dept;
}
return item.item;
}
popUpTreeGridView.addEventListener(Event.CHANGE, (event:Event) -> {
var popUpTreeGridView = cast(event.currentTarget, TreeGridView);
trace("PopUpTreeGridView changed: " + popUpTreeGridView.selectedLocation + " " + popUpTreeGridView.selectedItem.item);
});
this.addChild(popUpTreeGridView);
Events:
openfl.events.Event.CHANGE | Dispatched when either
|
---|---|
openfl.events.Event.OPEN | Dispatched when the pop-up tree grid view is opened. |
openfl.events.Event.CLOSE | Dispatched when the pop-up tree grid view is closed. |
feathers.events.TreeGridViewEvent.ITEM_TRIGGER | Dispatched when the user taps or clicks an item renderer in the pop-up tree grid view. The pointer must remain within the bounds of the item renderer on release, and the tree view cannot scroll before release, or the gesture will be ignored. |

Constructor
new(?dataProvider:IHierarchicalCollection<Dynamic>, ?changeListener:Event ‑> Void)

object.

.Variables
buttonFactory:AbstractDisplayObjectFactory<Dynamic, Button>
Creates the button, which must be of type feathers.controls.Button
.
In the following example, a custom button factory is provided:
popUpTreeGridView.buttonFactory = () ->
{
return new Button();
};

cellRendererRecycler:AbstractDisplayObjectRecycler<Dynamic, TreeGridViewCellState, DisplayObject>
Manages cell renderers used by the pop-up tree grud view.
In the following example, the pop-up tree grid view uses a custom item renderer class:
popUpTreeGridView.itemRendererRecycler = DisplayObjectRecycler.withClass(CustomItemRenderer);

columns:IFlatCollection<TreeGridViewColumn>
Defines the set of columns to display for each item in the pop-up tree
grid view's data provider. If null
, the tree grid view will attempt to
populate the columns automatically using
reflection.
The following example passes in a data provider and tells the columns how to interpret the data:
popUpTreeGridView.dataProvider = new ArrayHierarchicalCollection([
{ item: "Chicken breast", dept: "Meat", price: "5.90" },
{ item: "Butter", dept: "Dairy", price: "4.69" },
{ item: "Broccoli", dept: "Produce", price: "2.99" },
{ item: "Whole Wheat Bread", dept: "Bakery", price: "2.49" }
]);
popUpTreeGridView.columns = new ArrayCollection([
new TreeGridViewColumn("Item", (data) -> data.item),
new TreeGridViewColumn("Department", (data) -> data.dept),
new TreeGridViewColumn("Price", (data) -> data.price)
]);

customButtonVariant:String
A custom variant to set on the button, instead of
PopUpTreeGridView.CHILD_VARIANT_BUTTON
.
The customButtonVariant
will be not be used if the result of
buttonFactory
already has a variant set.

customTreeGridViewVariant:String
A custom variant to set on the pop-up tree grid view, instead of

.
The customTreeGridViewVariant
will be not be used if the result of
treeGridViewFactory
already has a variant set.

dataProvider:IHierarchicalCollection<Dynamic>
The collection of data displayed by the pop-up tree grid view.
Items in the collection must be class instances or anonymous structures. Do not add primitive values (such as strings, booleans, or numeric values) directly to the collection.
Additionally, all items in the collection must be unique object instances. Do not add the same instance to the collection more than once because a runtime exception will be thrown.
The following example passes in a data provider and tells the columns how to interpret the data:
popUpTreeGridView.dataProvider = new ArrayHierarchicalCollection([
{ item: "Chicken breast", dept: "Meat", price: "5.90" },
{ item: "Butter", dept: "Dairy", price: "4.69" },
{ item: "Broccoli", dept: "Produce", price: "2.99" },
{ item: "Whole Wheat Bread", dept: "Bakery", price: "2.49" }
]);
popUpTreeGridView.columns = new ArrayCollection([
new TreeGridViewColumn("Item", (data) -> data.item),
new TreeGridViewColumn("Department", (data) -> data.dept),
new TreeGridViewColumn("Price", (data) -> data.price)
]);

read onlyopen:Bool
Indicates if the tree grid view pop-up is open or closed.
feathersui-data-containers-pack 1.0.0
.See also:
popUpAdapter:IPopUpAdapter
Manages how the tree grid view is displayed when it is opened and closed.
In the following example, a custom pop-up adapter is provided:
popUpTreeGridView.popUpAdapter = new DropDownPopUpAdapter();
feathersui-data-containers-pack 1.0.0
.prompt:String
The text displayed by the button when no item is selected.
The following example sets the pop-up tree grid view's prompt:
popUpTreeGridView.prompt = "Select an item";
feathersui-data-containers-pack 1.0.0
.selectedItem:Dynamic
feathersui-data-containers-pack 1.0.0
.See also:
feathers.core.IDataSelector.selectedItem
selectedLocation:Array<Int>
The currently selected location. Returns null
if no location is
selected.
The following example selects a specific location:
popUpTreeGridView.selectedLocation = [2, 0];
The following example clears the currently selected location:
popUpTreeGridView.selectedLocation = null;
The following example listens for when the selection changes, and it prints the new selected location to the debug console:
var popUpTreeGridView = new PopUpTreeGridView();
function changeHandler(event:Event):Void
{
var popUpTreeGridView = cast(event.currentTarget, PopUpTreeGridView);
trace("selection change: " + popUpTreeGridView.selectedLocation);
}
popUpTreeGridView.addEventListener(Event.CHANGE, changeHandler);

.treeGridViewFactory:AbstractDisplayObjectFactory<Dynamic, TreeGridView>
Creates the tree grid view that is displayed as a pop-up. The tree grid
view must be of type feathers.controls.TreeGridView
.
In the following example, a custom tree grid view factory is provided:
popUpTreeGridView.treeGridViewFactory = () ->
{
return new TreeGridView();
};

Methods
closeTreeGridView():Void
Closes the pop-up tree grid, if it is open.
The following example closes the pop-up tree grid:
if(popUpTreeGridView.open)
{
popUpTreeGridView.closeGridView();
}
When the pop-up tree closes, the component will dispatch an event of
type Event.CLOSE
.
feathersui-data-containers-pack 1.0.0
.See also:
dynamicitemToText(data:Dynamic):String
Converts an item to text to display within the Button
, if the item is
selected. By default, the toString()
method is called to convert an
item to text. This method may be replaced to provide custom text.
For example, consider the following item:
{ text: "Example Item" }
If the Button
should display the text "Example Item", a custom
implementation of itemToText()
might look like this:
popUpTreeGridView.itemToText = (item:Dynamic) -> {
return item.text;
};
feathersui-data-containers-pack 1.0.0
.openTreeGridView():Void
Opens the pop-up tree grid, if it is not already open.
The following example opens the pop-up tree grid:
if(!popUpTreeGridView.open)
{
popUpTreeGridView.openTreeGridView();
}
When the pop-up tree grid opens, the component will dispatch an event of
type Event.OPEN
.
