    Default QML disable button after other button_click event and enable again after timer timeou

    I would disable button after other button_click event and enable again after timer timeout. I tried with Timer and States with PropertyChanged, but it doesn't work.
    How I can send a qml signal to reload/refresh the page?

    When i click on id_button_add I would disable Id_button_edit and start a timer for 3 seconds. When the timer timeouts I enable already the id_button_edit.

    Here is my code.

    Qt Code:
    1. import QtQuick 2.0
    2. import QtQuick.Layouts 1.3
    3.  
    4. import "../items"

    22. }
    23.

    25. id_button_remove.button_enabled = ui_resident_model.sourceModel.rowCount() > 1
    26. }

    I found a solution --> bind qml property with cpp model and emit also in cpp module valueChanged() signal
