@Js

(Widget) - A table widget that displays Resources. ResourceTable is a wrapper around the FWT Table widget with the following enhancements:

A Resource specific table model.
Event data return the Resource that's been actioned.

Because ResourceTable does not extend fwt:Widget it can not be added directly. Instead, add the table field which returns the wrapped FWT Table instance.

table := ResourceTable(reflux)
ContentPane() {
    it.content = table.table
}

make

Source

new make(Reflux reflux, |This? in := null)

Creates a ResourceTable. Use the ctor to pass in a table:

ResourceTable(reflux) {
    it.table = Table {
        it.border = false
    }
    it.roots = myRoots
    it.model = MyModel()
}

Note that, as shown above, the table must be set before the model and / or roots.

model

Source

ResourceTableModel model := ResourceTableModelImpl.<ctor>()

The model that customises the look of the table. Leave as is for default behaviour.

You should call refreshAll after setting a new model.

onAction

Source

EventListeners onAction()

Callback when a row is double clicked or Return/Enter key is pressed.

Event id fired:

EventId.modified

Event fields:

Event.data: the Resource actioned

onPopup

Source

EventListeners onPopup()

Callback when user invokes a right click popup action. If the callback wishes to display a popup, then set the Event.popup field with menu to open. If multiple callbacks are installed, the first one to return a nonnull popup consumes the event.

To show a menu created from the Resource, add the following:

table.onPopup.add |Event event| {
    event.popup = (event.data as Resource)?.populatePopup(Menu())
}

Event id fired:

EventId.popup

Event fields:

Event.data: the Resource selected, or null if this is a background popup.
Event.pos: the mouse position of the popup.
